The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
Chapter 1. Introduction
11
1. Introduction
1.1. Welcome
This is the manual for Rockbox. Rockbox is an open source firmware replacement
for a growing number of digital audio players. Rockbox aims to be considerably more
functional and efficient than your device’s stock firmware while remaining easy to use
and customisable. Rockbox is written by users, for users. Not only is it free to use, it
is also released under the GNU General Public License (GPL), which means that it will
always remain free both to use and to change.
Rockbox has been in development since 2001, and receives new features, tweaks and
fixes each day to provide you with the best possible experience on your digital audio
player. A major goal of Rockbox is to be simple and easy to use, yet remain very
customisable and configurable. We believe that you should never need to go through a
series of menus for an action you perform frequently. We also believe that you should
be able to configure almost anything about Rockbox you could want, pertaining to
functionality. Another top priority of Rockbox is audio playback quality – Rockbox,
for most models, includes a wider range of sound settings than the device’s original
firmware. A lot of work has been put into making Rockbox sound the best it can, and
improvements are constantly being made. All models have access to a large number
of plugins, including many games, applications, and graphical “demos”. You can load
different configurations quickly for different purposes (e.g. a large font for in your car,
different sound settings for at home). Rockbox features a very wide range of languages,
and all supported models also have the ability to talk to you – menus can be voiced and
filenames spelled out or spoken.
1.2. Getting more help
This manual is intended to be a comprehensive introduction to the Rockbox firmware.
There is, however, more help available. The Rockbox website at http://www.rockbox.org/
contains very extensive documentation and guides written by members of the Rockbox
community and this should be your first port of call when looking for further help.
If you cannot find the information you are searching for on the Rockbox website there
are a number of support channels you should have a look at. You can try the Rockbox
forums located at http://forums.rockbox.org/. The mailing lists are another option, and
can be found at http://www.rockbox.org/mail/. From that page you can subscribe to
the lists and browse the archives. To search the list archives simply use the search field
that is located on the left side of the website. Furthermore, you can ask on IRC. The
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
Chapter 1. Introduction
12
main channel for Rockbox is #rockbox on irc://irc.freenode.net. Many helpful developers
and users are usually around. Just join and ask your question (don’t ask to ask!) – if
someone knows the answer you’ll usually get an answer pretty quickly. More information
including IRC logs can be found at http://www.rockbox.org/irc/. We also have a web
client so that you can join the Rockbox IRC channel without needing to install additional
software onto your computer.
If you think you have found a bug please make sure it actually is a bug and is still
present in the most recent version of Rockbox. You should try to confirm that by using
the above mentioned support channels first. After that you can submit that issue to our
tracker. Refer to section G (page 204) for details on how to use the tracker.
1.3. Naming conventions and marks
We have some conventions (especially for naming) that are intended to be consistent
throughout this manual.
Manufacturer and product names are formatted in accordance with the standard rules
of English grammar, e.g. “Samsung playback is currently unsupported”. Manufacturer
and model names are proper nouns, and thus are written beginning with a capital letter.
This manual has some parts that are marked with icons on the margin to help you
finding important parts or parts you could skip. The following icons are used:
Note: This indicates a note. A note starts always with the text “Note”. In order to
make finding notes easier each one is accompanied by an icon in the margin as here.
Notes are used to mark useful information that may help you to get the most out of
Rockbox.
b
Warning: This is a warning. In contrast to notes mentioned above, a warning should
be taken more seriously. Whereas ignoring notes will not cause any serious damage,
ignoring warnings could cause serious damage to your player. You really should read the
warnings, especially if you are new to Rockbox.
!
This icon marks a section that is intended especially for the blind and visually impaired. As they cannot read the manual in the same way sighted people do we have
added some additional descriptions. If you are not blind or visually impaired you can
probably completely skip these blocks. To make this easier, there is an icon shown in
the margin on the right.
Links to the wiki are abbreviated by the name of the wiki page. Those names are still
linked so you can simply follow them like any other link in this manual. If you want to
access a wiki page manually go to Z http://www.rockbox.org/wiki/ and type the page
name in the “Go” box at the top of the page. Links to wiki pages are also indicated by
the symbol Z in front of the page name.

Chapter 2. Installation
2. Installation
Installing Rockbox is generally a quick and easy procedure. However before beginning
there are a few important things to know.
2.1. Before Starting
USB connection. To transfer Rockbox to your player you need to connect it to your
computer. For manual installation/uninstallation, or should autodetection fail
during automatic installation, you need to know where to access the player. On
Windows this means you need to know the drive letter associated with the player.
On Linux you need to know the mount point of your player. On Mac OS X you
need to know the volume name of your player.
The installation requires you to use UMS mode. In order to start up your YH-820
in UMS mode you need to:
1. Turn off the player (Original Firmware).
2. Connect your YH-820 to the computer using the data cable.
The player will now appear as a regular disk on your computer.
2.2. Installing Rockbox
There are two ways to install Rockbox: automated and manual. The automated way is
the preferred method of installing Rockbox for the majority of people. Rockbox Utility
is a graphical application that does almost everything for you. However, should you
encounter a problem, then the manual way is still available to you.
There are three separate components, two of which need to be installed in order to
run Rockbox:
The Samsung bootloader. The Samsung bootloader is the program that tells your
player how to load and start the original firmware. It is also responsible for any
emergency, recovery, or disk modes on your player. This bootloader is stored
in special flash memory in your Samsung and comes factory-installed. It is not
necessary to modify this in order to install Rockbox.
The Rockbox bootloader. The Rockbox bootloader is loaded from disk by the Samsung
bootloader. It is responsible for loading the Rockbox firmware and for providing
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820

Chapter 2. Installation
the dual boot function. It directly replaces the Samsung firmware in the player’s
boot sequence.
The Rockbox firmware. Similar to the Samsung firmware, most of the Rockbox code is
contained in a “build” that resides on your player’s drive. This makes it easy to
update Rockbox. The build consists of a directory called .rockbox which contains
all of the Rockbox files, and is located in the root of your player’s drive.
Apart from the required parts there are some addons you might be interested in
installing.
Fonts. Rockbox can load custom fonts. The fonts are distributed as a separate package
and thus need to be installed separately. They are not required to run Rockbox
itself but a lot of themes require the fonts package to be installed.
Themes. The appearance of Rockbox can be customised by themes. Depending on your
taste you might want to install additional themes to change the look of Rockbox.
2.2.1. Automated Installation
To automatically install Rockbox, download the official installer and housekeeping tool
Rockbox Utility. It allows you to:
• Automatically install all needed components for using Rockbox (“Minimal Installation”).
• Automatically install all suggested components (“Complete Installation”).
• Selectively install optional components.
• Install additional fonts and themes.
• Install voice files and generate talk clips.
• Uninstall all components you installed using Rockbox Utility.
Prebuilt binaries for Windows, Linux and Mac OS X are available at the ZRockboxUtility
wiki page.
When first starting Rockbox Utility run “Autodetect”, found in the configuration
dialog (File → Configure). Autodetection can detect most player types. If autodetection
fails or is unable to detect the mountpoint, make sure to enter the correct values. The
mountpoint indicates the location of the player in your filesystem. On Windows, this is
the drive letter the player gets assigned, on other systems this is a path in the filesystem.

Chapter 2. Installation
Choosing a Rockbox version
There are three different versions of Rockbox available from the Rockbox website: Release version, current build and archived daily build. You need to decide which one you
want to install and get the appropriate version for your player. If you select either “Minimal Installation” or “Complete Installation” from the “Quick Start” tab, then Rockbox
Utility will automatically install the release version of Rockbox. Using the “Installation”
tab will allow you to select which version you wish to install.
Release. The release version is the latest stable release, free of known critical bugs.
For a manual install, the current stable release of Rockbox is available at http:
//www.rockbox.org/download/.
Development Build. The development build is built at each change to the Rockbox
source code repository and represents the current state of Rockbox development.
This means that the build could contain bugs but most of the time is safe to use.
For a manual install, you can download the current build from http://build.rockbox.
org/.
Archived Build. In addition to the release version and the current build, there is also
an archive of daily builds available for download. These are built once a day from
the latest source code in the repository. For a manual install, you can download
archived builds from http://www.rockbox.org/daily.shtml.
Note: Because current and archived builds are development versions that change frequently, they may behave differently than described in this manual, or they may introduce new (and potentially annoying) bugs. Unless you wish to try the latest and
greatest features at the price of possibly greater instability, or you wish to help with
development, you should stick with the release.
Please now go to section 2.2.3 (page 16) to complete the installation procedure.
2.2.2. Manual Installation
The manual installation method is still available to you, should you need or desire it by
following the instructions below. If you have used Rockbox Utility to install Rockbox,
then you do not need to follow the next section and can skip straight to section 2.2.3
(page 16)
Installing the firmware
1. Download your chosen version of Rockbox from the links in the previous section.
2. Connect your player to the computer via USB in MSC mode as described in the
manual that came with your player.

3. Take the .zip file that you downloaded and use the “Extract all” command of
your unzip program to extract the files onto your player.
Note: The entire contents of the .zip file should be extracted directly to the root of
your player’s drive. Do not try to create a separate directory on your player for the
Rockbox files! The .zip file already contains the internal structure that Rockbox needs.
b
If the contents of the .zip file are extracted correctly, you will have a directory called
.rockbox, which contains all the files needed by Rockbox, in the main directory of your
player’s drive.
Installing the bootloader

1. Download http://download.rockbox.org/bootloader/samsung/yh820/FW_YH820.
mi4
2. Connect your YH-820 to the computer using UMS mode.
3. Rename the FW_YH820.mi4 file to OF.mi4 in the System directory on your YH-820.
Note: You should keep a safe backup of this file for use if you ever wish to switch
back to the Samsung firmware.
b
Note: If you cannot see the System directory, you will need to make sure your
operating system is configured to show hidden files and directories.
b
4. Copy the FW_YH820.mi4 file you downloaded to the System directory on your
player.
2.2.3. Finishing the install
Safely eject / unmount the USB drive, unplug the cable and restart.
2.2.4. Enabling Speech Support (optional)
If you wish to use speech support you will also need a voice file. Voice files allow Rockbox
to speak the user interface to you. Rockbox Utility can install an English voice file, or
you can download it from http://www.rockbox.org/daily.shtml and unzip it to the root
of your player. Rockbox Utility can also aid you in the creation of voice files with
different voices or in other languages if you have a suitable speech engine installed on
your computer. Voice menus are enabled by default and will come into effect after a
reboot. See section 8.10 (page 74) for details on voice settings. Rockbox Utility can also
aid in the production of talk files, which allow Rockbox to speak file and folder names.

Chapter 2. Installation
2.3. Running Rockbox
When you turn the unit on, Rockbox should load.
2.4. Updating Rockbox
Rockbox can be easily updated with Rockbox Utility. You can also update Rockbox
manually – download a Rockbox build as detailed above, and unzip the build to the root
directory of your player as in the manual installation stage. If your unzip program asks
you whether to overwrite files, choose the “Yes to all” option. The new build will be
installed over your current build.
The bootloader only changes rarely, and should not normally need to be updated.
Note: If you use Rockbox Utility be aware that it cannot detect manually installed
components.
b
2.5. Uninstalling Rockbox
Note: The Rockbox bootloader allows you to choose between Rockbox and the original
firmware. (See section 3.1.3 (page 20) for more information.)
2.5.1. Automatic Uninstallation
You can uninstall Rockbox automatically by using Rockbox Utility. If you installed
Rockbox manually you can still use Rockbox Utility for uninstallation but will not be
able to do this selectively.
2.5.2. Manual Uninstallation
If you would like to go back to using the original Samsung software, connect the player to
your computer, and delete the FW_YH820.mi4 file and rename OF.mi4 to FW_YH820.mi4
in the System directory on your YH-820. As in the installation, it may be necessary to
first put your device into UMS mode.
If you wish to clean up your disk, you may also wish to delete the .rockbox directory
and its contents. Turn the Samsung off. Turn the player back on and the original
Samsung software will load.
2.6. Troubleshooting
“File Not Found” If you receive a “File Not Found” from the bootloader, then the
bootloader cannot find the Rockbox firmware. This is usually a result of not

extracting the contents of the .zip file to the proper location, and should not
happen when Rockbox has been installed with Rockbox Utility.
To fix this, either install Rockbox with the Rockbox Utility which will take care
of this for you, or recheck the Manual Install section to see where the files need to
be located.

Throughout this manual, the buttons on the player are labelled according to the
picture above. Whenever a button name is prefixed by “Long”, a long press of approximately one second should be performed on that button. The buttons are described in
detail in the following paragraph. Additional information for blind users is available on
the Rockbox website at ZBlindFAQ.
Hold or lay the player so that the side with the controls and LCD is facing towards
you. Directly below the bottom edge of the screen are three buttons: Rewind on the
left, Play in the middle and Forward on the right. Below them is a four-way pad which
contains the Down, Up, Left and Right controls.
At the top of the right hand side of the player is the Rec button.
On the top panel of the player, from left to right, you can find the following: headphone
socket, line-in socket, internal microphone, and the Hold switch. Note that when the
Hold switch is moved towards the center of the player, hold is turned on and all the
other controls are disabled. Be sure Hold is off before trying to use your player.
At the top of the back side of the player, just under the Hold button is the reset hole,
if you need to perform a hardware reset.

Chapter 3. Quick Start
The USB/dock connector that is used to connect your player to your computer is on
the bottom panel of the player.
3.1.2. Turning the player on and off
To turn on and off your Rockbox enabled player use the following keys:
Key
Action
Long Play
Long Play
Start Rockbox
Shutdown Rockbox
On shutdown, Rockbox automatically saves its settings.
In the unlikely event of a software failure, a hardware reset can be performed by
inserting a paperclip gently into the Reset hole.
3.1.3. Starting the original firmware
Rockbox has a dual-boot feature. It loads the original firmware from the file /System/OF.mi4.
To boot into the original firmware, press and hold for awhile the Play button and then
immediately after the Samsung logo appears, press the Left button and keep it pressed
until the original firmware starts.
3.1.4. Putting music on your player
Note: Due to a bug in some OS X versions, the player can not be mounted, unless the
USB HID feature is disabled. See section 8.5.6 (page 68) for more information.
With the player connected to the computer as an MSC/UMS device (like a USB
Drive), music files can be put on the player via any standard file transfer method that
you would use to copy files between drives (e.g. Drag-and-Drop). Files may be placed
wherever you like on the player, but it is strongly suggested NOT to put them in the
/.rockbox folder and instead put them in any other folder, e.g. /, /music or /audio.
The default directory structure that is assumed by some parts of Rockbox (album art
searching, and missing-tag fallback in some WPSes) uses the parent directory of a song
as the Album name, and the parent directory of that folder as the Artist name. WPSes
may display information incorrectly if your files are not properly tagged, and you have
your music organized in a way different than they assume when attempting to guess the
Artist and Album names from your filetree. See section C (page 179) for the requirements
for Album Art to work properly. See section B.1 (page 173) for a list of supported
audio formats.

3.1.5. The first contact
After you have first started the player, you’ll be presented by the Main Menu. From
this menu you can reach every function of Rockbox, for more information (see section 5.1
(page 39)). To browse the files on your player, select Files (see section 4.1 (page 23)),
and to browse in a view that is based on the meta-data1 of your audio files, select
Database (see section 4.2 (page 27)).
3.1.6. Basic controls
When browsing files and moving through menus you usually get a list view presented.
The navigation in these lists are usually the same and should be pretty intuitive. In the
tree view use Down and Up to move around the selection. Use Right to select an item.
When browsing the file system selecting an audio file plays it. The view switches to the
“While playing screen”, usually abbreviated as “WPS” (see section 4.3 (page 30). The
dynamic playlist gets replaced with the contents of the current directory. This way you
can easily treat directories as playlists. The created dynamic playlist can be extended
or modified while playing. This is also known as “on-the-fly playlist”. To go back to
the File Browser stop the playback with the Long Play button or return to the file
browser while keeping playback running using Right. In list views you can go back one
step with Left.
3.1.7. Basic concepts
Playlists
Rockbox is playlist oriented. This means that every time you play an audio file, a socalled “dynamic playlist” is generated, unless you play a saved playlist. You can modify
the dynamic playlist while playing and also save it to a file. If you do not want to use
playlists you can simply play your files directory based. Playlists are covered in detail
in section 4.4 (page 35).
Menu
From the menu you can customise Rockbox. Rockbox itself is very customisable. Also
there are some special menus for quick access to frequently used functions.
Context Menu
Some views, especially the file browser and the WPS have a context menu. From the file
browser this can be accessed with Long Right. The contents of the context menu vary,
depending on the situation it gets called. The context menu itself presents you with
some operations you can perform with the currently highlighted file. In the file browser
this is the file (or directory) that is highlighted by the cursor. From the WPS this is

the currently playing file. Also there are some actions that do not apply to the current
file but refer to the screen from which the context menu gets called. One example is the
playback menu, which can be called using the context menu from within the WPS.
3.2. Customising Rockbox
Rockbox’ User Interface can be customised using “Themes”. Themes usually only affect
the visual appearance, but an advanced user can create a theme that also changes various
other settings like file view, LCD settings and all other settings that can be modified
using .cfg files. This topic is discussed in more detail in section 13.3 (page 166). The
Rockbox distribution comes with some themes that should look nice on your player.
Note: Some of the themes shipped with Rockbox need additional fonts from the fonts
package, so make sure you installed them. Also, if you downloaded additional themes
from the Internet make sure you have the needed fonts installed as otherwise the theme
may not display properly.
b
3.3. USB Charging
To charge your player over USB, hold any button while plugging it in. This will prevent
it from connecting to your computer and let you continue to use it normally. Your player
must already be in Rockbox for this to function.
Note: Be aware that this button may still perform its normal function, so it is recommended to use a button without harmful side effects, such as Rewind.

4.1. File Browser
Figure 4.1.: The file browser
Rockbox lets you browse your music in either of two ways. The File Browser lets
you navigate through the files and directories on your player, entering directories and
executing the default action on each file. To help differentiate files, each file format is
displayed with an icon.
The Database Browser, on the other hand, allows you to navigate through the
music on your player using categories like album, artist, genre, etc.
You can select whether to browse using the File Browser or the Database Browser
by selecting either Files or Database in the Main Menu. If you choose the File
Browser, the Show Files setting lets you select what types of files you wish to view.
See section 8.2 (page 63) for more information on the Show Files setting.
Note: The File Browser allows you to manipulate your files in ways that are not
available within the Database Browser. Read more about Database in section 4.2
(page 27). The remainder of this section deals with the File Browser.

The Context Menu contains the following options (unless otherwise noted, each
option pertains both to files and directories):
Playlist. Enters the Playlist Submenu (see section 4.4.3 (page 36)).
Playlist Catalogue. Enters the Playlist Catalogue Submenu (see section 4.4.2 (page 36)).
Rename. This function lets the user modify the name of a file or directory.
Cut. Copies the name of the currently selected file or directory to the clipboard and
marks it to be ‘cut’.
Copy. Copies the name of the currently selected file or directory to the clipboard and
marks it to be ‘copied’.
Paste. Only visible if a file or directory name is on the clipboard. When selected it will
move or copy the clipboard to the current directory.
Delete. Deletes the currently selected file. This option applies only to files, and not to
directories. Rockbox will ask for confirmation before deleting a file. Press Right
to confirm deletion or any other key to cancel.
Delete Directory. Deletes the currently selected directory and all of the files and subdirectories it may contain. Deleted directories cannot be recovered. Use this feature
with caution!
Set As Backdrop. Set the selected bmp file as background image. The bitmaps need to
meet the conditions explained in section 13.1.6 (page 159).
Open with. Runs a viewer plugin on the file. Normally, when a file is selected in Rockbox, Rockbox automatically detects the file type and runs the appropriate plugin.
The Open With function can be used to override the default action and select a
viewer by hand. For example, this function can be used to view a text file even if
the file has a non-standard extension (i.e., the file has an extension of something
other than .txt). See section 12.3 (page 121) for more details on viewers.
Create Directory. Create a new directory in the current directory on the disk.
Properties. Shows properties such as size and the time and date of the last modification
for the selected file. If used on a directory, the number of files and subdirectories
will be shown, as well as the total size.
Set As Recording Directory. Save recordings in the selected directory.
Start File Browser Here. This option allows users to set the currently selected directory
as the default start directory for the file browser. This option is not available for
files.
Note: If you have Auto-Change Directory and Constrain Auto-Change

enabled, the directories returned will be constrained to the directory you have
chosen here and those below it. See section 7.12 (page 59)
Add to Shortcuts. Adds a link to the selected item in the shortcuts.link file. If the
file does not already exist it will be created in the root directory. Note that if you
create a shortcut to a file, Rockbox will not open it upon selecting, but simply
bring you to its location in the File Browser.
4.1.3. Virtual Keyboard
Figure 4.3.: The virtual keyboard
This is the virtual keyboard that is used when entering text in Rockbox, for example
when renaming a file or creating a new directory. The virtual keyboard can be easily
changed by making a text file with the required layout. More information on how to
achieve this can be found on the Rockbox website at ZLoadableKeyboardLayouts.
Also you can switch to Morse code input mode by changing the Use Morse Code

4.2. Database
4.2.1. Introduction
This chapter describes the Rockbox music database system. Using the information
contained in the tags (ID3v1, ID3v2, Vorbis Comments, Apev2, etc.) in your audio
files, Rockbox builds and maintains a database of the music files on your player and
allows you to browse them by Artist, Album, Genre, Song Name, etc. The criteria the
database uses to sort the songs can be completely customised. More information on how
to achieve this can be found on the Rockbox website at ZDataBase.
4.2.2. Initializing the Database
The first time you use the database, Rockbox will scan your disk for audio files. This can
take quite a while depending on the number of files on your player. This scan happens
in the background, so you can choose to return to the Main Menu and continue to listen
to music. If you shut down your player, the scan will continue next time you turn it on.
After the scan is finished you may be prompted to restart your player before you can
use the database.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
28
Chapter 4. Browsing and playing
Ignoring Directories During Database Initialization
You may have directories on your player whose contents should not be added to the
database. Placing a file named database.ignore in a directory will exclude the files in
that directory and all its subdirectories from scanning their tags and adding them to the
database. This will speed up the database initialization.
If a subdirectory of an ‘ignored’ directory should still be scanned, place a file named
database.unignore in it. The files in that directory and its subdirectories will be
scanned and added to the database.
4.2.3. The Database Menu
Auto Update If Auto update is set to on, each time the player boots, the database
will automatically be updated.
Initialize Now You can force Rockbox to rescan your disk for tagged files by using the
Initialize Now function in the Database Menu.
Warning: Initialize Now removes all database files (removing runtimedb data
also) and rebuilds the database from scratch.
!
Update Now Update now causes the database to detect new and deleted files
Note: Unlike the Auto Update function, Update Now will update the database
regardless of whether the Directory Cache is enabled. Thus, an update using
Update now may take a long time.
Unlike Initialize Now, the Update Now function does not remove runtime
database information.
Gather Runtime Data When enabled, rockbox will record how often and how long a
track is being played, when it was last played and its rating. This information can
be displayed in the WPS and is used in the database browser to, for example, show
the most played, unplayed and most recently played tracks.
Export Modifications This allows for the runtime data to be exported to the file
/.rockbox/database_changelog.txt, which backs up the runtime data in ASCII
format. This is needed when database structures change, because new code cannot
read old database code. But, all modifications exported to ASCII format should
be readable by all database versions.
Import Modifications. Allows the /.rockbox/database_changelog.txt backup to be
conveniently loaded into the database. If Auto Update is enabled this is performed automatically when the database is initialized.

4.2.4. Using the Database
Once the database has been initialized, you can browse your music by Artist, Album, Genre, Song Name, etc. To use the database, go to the Main Menu and select
Database.
Note: You may need to increase the value of the Max Entries in File Browser
setting (Settings → General Settings → System → Limits) in order to view long
lists of tracks in the ID3 database browser.
There is no option to turn off database completely. If you do not want to use it just
do not do the initial build of the database and do not load it to RAM.

4.3. While Playing Screen
The While Playing Screen (WPS) displays various pieces of information about the currently playing audio file. The appearance of the WPS can be configured using WPS
configuration files. The items shown depend on your configuration – all items can be
turned on or off independently. Refer to section D (page 181) for details on how to
change the display of the WPS.
• Status bar: The Status bar shows Battery level, charger status, volume, play mode,
repeat mode, shuffle mode and clock. In contrast to all other items, the status bar
is always at the top of the screen.
• (Scrolling) path and filename of the current song.
• The ID3 track name.
• The ID3 album name.
• The ID3 artist name.
• Bit rate. VBR files display average bitrate and “(avg)”
• Elapsed and total time.
• A slidebar progress meter representing where in the song you are.
• Peak meter.
See section 13.2 (page 160) for details of customising your WPS (While Playing

Delete
Delete the currently playing file. The file will be deleted but the playback of the file will
not stop immediately. Instead, the part of the file that has already been buffered (i.e.
read into the player’s memory) will be played. This may even be the whole track.
Pitch
The Pitch Screen allows you to change the rate of playback (i.e. the playback speed
and at the same time the pitch) of your player. The rate value can be adjusted between
50% and 200%. 50% means half the normal playback speed and a pitch that is an octave
lower than the normal pitch. 200% means double playback speed and a pitch that is an
octave higher than the normal pitch.
The rate can be changed in two modes: procentual and semitone. Initially, procentual
mode is active.
If you’ve enabled the Timestretch option in Sound Settings and have since rebooted, you can also use timestretch mode. This allows you to change the playback
speed without affecting the pitch, and vice versa.
In timestretch mode there are separate displays for pitch and speed, and each can be
altered independently. Due to the limitations of the algorithm, speed is limited to be
between 35% and 250% of the current pitch value. Pitch must maintain the same ratio
as well as remain between 50% and 200%.
The value of the rate, pitch and speed is not persistent, i.e. after the player is turned
on it will always be set to 100%. However, the rate, pitch and speed information will be
stored in any bookmarks you may create (see section 8.7 (page 71)) and will be restored
upon playing back those bookmarks.

4.4. Working with Playlists
4.4.1. Playlist terminology
Some common terms that are used in Rockbox when referring to playlists:
Directory. A playlist! One of the keys to getting the most out of Rockbox is understanding that Rockbox always considers the song that it is playing to be part of a
playlist, and in some situations, Rockbox will create a playlist automatically. For
example, if you are playing the contents of a directory, Rockbox will automatically
create a playlist containing all songs in it. This means that just about anything
that is described in this chapter with respect to playlists also applies to directories.
Dynamic playlist. A dynamic playlist is a playlist that is created “On the fly.” Any
time you insert or queue tracks using the Playlist submenu (see section 4.4.3
(page 36)), you are creating (or adding to) a dynamic playlist.
Insert. In Rockbox, to Insert an item into a playlist means putting an item into a
playlist and leaving it there, even after it is played. As you will see later in this
chapter, Rockbox can Insert into a playlist in several places.
Queue. In Rockbox, to Queue a song means to put the song into a playlist and then
to remove the song from the playlist once it has been played. The only difference
between Insert and Queue is that the Queue option removes the song from the
playlist once it has been played, and the Insert option does not.
4.4.2. Creating playlists
Rockbox can create playlists in four different ways.
By selecting (“playing”) a song from the File Browser
Whenever a song is selected from the File Browser with Right, Rockbox will automatically create a playlist containing all of the songs in that directory and start playback
with the selected song.
Note: If you already have created a dynamic playlist, playing a new song will erase the
current dynamic playlist and create a new one. If you want to add a song to the current
playlist rather than erasing the current playlist, see the section below on how to add
music to a playlist.
By using Insert and Queue functions
If playback is stopped, the Insert and Queue functions can be used as described in
4.4.3 to create a new playlist instead of adding to an existing one. This will erase any
dynamic playlist.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
b
Chapter 4. Browsing and playing
36
By using the Playlist catalogue
The Playlist catalogue makes it possible to modify and create playlists that are
not currently playing. To do this select Playlist catalogue in the Context Menu.
There you will have two choices, Add to playlist adds the selected track or directory
to an existing playlist and Add to a new playlist creates a new playlist containing
the selected track or directory.
Note: All playlists in the Playlist catalogue are stored by default in the /Playlists
directory in the root of your player’s disk and playlists stored in other locations are not
included in the catalogue. It is however possible to move existing playlists there (see
section 4.1.2 (page 24)).
By using the Main Menu
To create a playlist containing all music on your player, you can use the Create
Playlist command in the Playlists menu found in the Main Menu. The created
playlist will be named root.m3u8 and saved in the root of your player’s disk.
4.4.3. Adding music to playlists
Adding music to a dynamic playlist
Figure 4.5.: The Playlist Submenu
The Playlist Submenu is a submenu in the Context Menu (see section 4.1.2 (page 24)),
it allows you to put tracks into a “dynamic playlist”. If there is no music currently playing, Rockbox will create a new dynamic playlist and put the selected track(s) into it.
If there is music currently playing, Rockbox will put the selected track(s) into the current playlist. The place in which the newly selected tracks are added to the playlist is
determined by the following options:
Insert. Add track(s) immediately after any tracks added via the most recent Insert
operation. If no tracks have yet been added via an Insert, new tracks will be
added immediately after the current playing track. If playback is stopped a new
dynamic playlist will get created with the selected tracks.

Chapter 4. Browsing and playing
Insert Next. Add track(s) immediately after current playing track, no matter what else
has been inserted.
Insert Last. Add track(s) to end of playlist.
Insert Shuffled. Add track(s) to the playlist in a random order.
Insert Last Shuffled. Add tracks in a random order to the end of the playlist.
Queue. Queue is the same as Insert except queued tracks are deleted immediately from
the playlist after they have been played. Also, queued tracks are not saved to the
playlist file (see section 5.9 (page 43)).
Queue Next. Queue track(s) immediately after current playing track.
Queue Last. Queue track(s) at end of playlist.
Queue Shuffled. Queue track(s) in a random order.
Queue Last Shuffled. Queue tracks in a random order at the end of the playlist.
Play Next. Replaces all but the current playing track with track(s). Current playing
track is queued.
The Playlist Submenu can be used to add either single tracks or entire directories
to a playlist. If the Playlist Submenu is invoked on a single track, it will put only
that track into the playlist. On the other hand, if the Playlist Submenu is invoked
on a directory, Rockbox adds all of the tracks in that directory to the playlist.
Note: You can control whether or not Rockbox includes the contents of subdirectories
when adding an entire directory to a playlist. Set the Settings → General Settings
→ Playlist → Recursively Insert Directories setting to Yes if you would like
Rockbox to include tracks in subdirectories as well as tracks in the currently-selected
directory.
b
Dynamic playlists are saved so resume will restore them exactly as they were before
shutdown.
Note: To view, save or reshuffle the current dynamic playlist use the Playlist sub
menu in the WPS context menu or in the Main Menu.
4.4.4. Modifying playlists
Reshuffling
Reshuffling the current playlist is easily done from the Playlist sub menu in the WPS,
just select Reshuffle.

Moving and removing tracks
To move or remove a track from the current playlist enter the Playlist Viewer by
selecting View Current Playlist in the Playlist submenu in the WPS context
menu or the Main Menu. Once in the Playlist Viewer open the context menu on
the track you want to move or remove. If you want to move the track, select Move in
the context menu and then move the blinking cursor to the place where you want the
track to be moved and confirm with Right. To remove a track, simply select Remove
in the context menu.
4.4.5. Saving playlists
To save the current playlist either enter the Playlist submenu in the WPS Context
Menu (see section 4.3.3 (page 32)) and select Save Current Playlist or enter the
Playlist Options menu in the Main Menu and select Save Current Playlist.
Either method will bring you to the Virtual Keyboard (see section 4.1.3 (page 26)),
enter a filename for your playlist and accept it and you are done.
4.4.6. Loading saved playlists
Through the File Browser
Playlist files, like regular music tracks, can be selected through the File Browser.
When loading a playlist from disk it will replace the current dynamic playlist.
Through the Playlist catalogue
The Playlist catalogue offers a shortcut to all playlists in your player’s specified
playlist directory. It can be used like the File Browser.
4.5. Hotkeys
Hotkeys are shortcut keys for use in the File Browser and WPS screen. To use one,
press Rec within the File Browser or Rec within the WPS screen. The assigned
function will launch with reference to the current file or directory, if applicable. Each
screen has its own assignment. If there is no assignment for a given screen, the hotkey
is ignored.
The default assignment for the File Browser hotkey is Off, while the default for the
WPS hotkey is View Playlist.
The hotkey assignments are changed in the Hotkey menu (see section 8.11 (page 76))
under General Settings.

The Main Menu is the screen from which all of the Rockbox functions can be accessed.
This is the first screen you will see when starting Rockbox. To return to the Main
Menu, press the Long Left+Long Up button.
All settings are stored on the unit. However, Rockbox does not access the hard disk
solely for the purpose of saving settings. Instead, Rockbox will save settings when it
accesses the hard disk the next time, for example when refilling the music buffer or
navigating through the File Browser. Changes to settings may therefore not be saved
unless the player is shut down safely (see section 3.1.2 (page 20)).

The Settings menu allows you to set or adjust many parameters that affect the way
your player works. There are many submenus for different parameter areas. Every time
you are setting a value of a parameter, and that value is selected from a list of some
predefined available values, you can press Long Right, and the selection cursor will
jump to the default value for the parameter. You can then confirm or cancel the value.
This is useful if you have changed the value of the parameter from the default to some
other value and would like to restore the default value.

Selecting the Recording option in the Main Menu enters the Recording Screen,
whilst pressing Long Right enters the Recording Settings (see section 10 (page 79)).
The Recording Screen shows the time elapsed and the size of the file being recorded.
A peak meter is present to allow you set gain correctly. There is also a volume setting,
this will only affect the output level of the player and does not affect the recorded sound.
If enabled in the peak meter settings, a counter in front of the peak meters shows the
number of times the clip indicator was activated during recording. The counter is reset
to zero when starting a new recording.
Note: When you start a recording, the hard disk will spin up. This will cause the peak
meters to freeze in the process. This is expected behaviour, and nothing to worry about.
The recording continues during the spin up.

5.9. Playlists
This menu allows you to work with playlists. Playlists can be created in three ways.
Playing a file in a directory causes all the files in it to be placed in a playlist. Playlists can
be created manually by either using the Context Menu (see section 4.1.2 (page 24))
or using the Playlist menu. Both automatically and manually created playlists can be
edited using this menu.
Create Playlist: Rockbox will create a playlist with all tracks in the current directory
and all sub-directories. The playlist will be created one directory level “up” from
where you currently are.
View Current Playlist: Displays the contents of the playlist currently stored in memory.
Save Current Playlist: Saves the current dynamic playlist, excluding queued tracks, to
the specified file. If no path is provided then playlist is saved to the current
directory.
View Catalogue: Provides a simple interface to maintain several playlists (see section 4.4 (page 35)).
5.10. Plugins
With this option you can load and run various plugins that have been written for Rockbox. There are a wide variety of these supplied with Rockbox, including several games,
some impressive demos and a number of utilities. A detailed description of the different
plugins is to be found in section 12 (page 84).

to do so in the course of fixing a problem with Rockbox. If you think you have
messed up your settings by use of this menu please try to reset all settings before
asking for help.
5.12. Quick Screen
Although the Quick Screen is accessible from nearly everywhere, not just the Main
Menu, it is worth mentioning here. It allows rapid access to your four favourite settings.
The default settings are Shuffle (section 7 (page 55)), Repeat (section 7 (page 55))
and the Show Files (section 8.2 (page 63)) options, but almost all configurable options
in Rockbox can be placed on this screen. To change the options, navigate through the
menus to the setting you want to add and press Long Right. In the menu which appears
you will be given options to place the setting on the Quick Screen.
Press Long Left+Long Down to access it and Play or Forward to exit. The direction
buttons will modify the individual setting values as indicated by the arrow icons. Please
note that the settings at opposite sides of the screen cycle through the available options
in opposite directions. Therefore if you select the same setting at e.g. the top and
bottom of the quickscreen, then pressing up and down will cycle through this setting in
opposite directions.

6. Sound Settings
Figure 6.1.: The sound settings screen
The sound settings menu offers a selection of sound settings you may change to customise
your listening experience.
6.1. Volume
This setting adjusts the volume of your music. Like most professional audio gear and
many consumer audio products, Rockbox uses a decibel scale where 0 dB is a reference that indicates the maximum volume that the player can produce without possible
distortion (clipping). All values lower than this reference will be negative and yield a
progressively softer volume. Values higher than 0 dB are available and can be used to
raise the volume more than would otherwise be possible. These volume levels will ordinarily lead to distorted sound, but might work nicely for music that has an otherwise low
volume level. The volume can be adjusted from a minimum of -128 dB to a maximum
of 0 dB.
6.2. Bass
This setting emphasises or suppresses the lower (bass) frequencies in the sound. A value
of 0 dB means that bass sounds are unaltered (flat response). The minimum setting is
-24 dB and the maximum is 24 dB.
6.3. Volume Limit
This setting adjusts the maximum volume of your music. The setting is by default set
to the maximum volume which equals to no limit. To set a volume limit, select a volume

(version rUnversioned directory-141114)

Chapter 6. Sound Settings
48
from the list and the maximum volume will be limited to the selected value all over the
system.
6.4. Treble
This setting emphasises or suppresses the higher (treble) frequencies in the sound. A
value of 0 dB means that treble sounds are unaltered (flat response). The minimum
setting is -24 dB and the maximum is 24 dB.
6.5. Balance
This setting controls the balance between the left and right channels. The default, 0,
means that the left and right outputs are equal in volume. Negative numbers increase
the volume of the left channel relative to the right, positive numbers increase the volume
of the right channel relative to the left.
6.6. Channels
A stereo audio signal consists of two channels, left and right. The Channels setting
determines if these channels are to be combined in any way, and if so, in what manner
they will be combined. Available options are:
Stereo. Leave the audio signal unmodified.
Mono. Combine both channels and send the resulting signal to both stereo channels,
resulting in a monophonic output.
Custom. Allows you to manually specify a stereo width with the Stereo Width setting
described later in this chapter.
Mono Left. Plays the left channel in both stereo channels.
Mono Right. Plays the right channel in both stereo channels.
Karaoke. Removes all sound that is common to both channels. Since most music is
recorded with vocals being equally present in both channels to make the singer
sound centrally placed, this often (but not always) has the effect of removing the
voice track from a song. This setting also very often has other undesirable effects
on the sound.
6.7. Stereo Width
Stereo width allows you to manually specify the effect that is applied when the Channels setting is set to “custom”. All values below 100% will progressively mix the contents
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
49
Chapter 6. Sound Settings
of one channel into the other. This has the effect of gradually centering the stereo image, until you have monophonic sound at 0%. Values above 100% will progressively
remove components in one channel that is also present in the other. This has the effect
of widening the stereo field. A value of 100% will leave the stereo field unaltered.
6.8. Crossfeed
Crossfeed attempts to make the experience of listening to music on headphones more
similar to listening to music with stereo speakers. When you listen to music through
speakers, each ear will hear sound originating from both speakers. However, the sound
from the left speaker reaches your right ear slightly later than it does your left ear, and
vice versa.
The human ear and brain together are very good at interpreting the time differences
between direct sounds and reflected sounds and using that information to identify the
direction that the sound is coming from. On the other hand, when listening to headphones, each ear hears only the stereo channel corresponding to it. The left ear hears
only the left channel and the right ear hears only the right channel. The result is that
sound from headphones does not provide the same spatial cues to your ear and brain as
speakers, and might for that reason sound unnatural to some listeners.
The crossfeed function uses an algorithm to feed a delayed and filtered portion of the
signal from the right channel into the left channel and vice versa in order to simulate the
spatial cues that the ear and brain receive when listening to a set of loudspeakers placed
in front of the listener. The result is a more natural stereo image that can be especially
appreciated in older rock and jazz records, where one instrument is often hard-panned
to just one of the speakers. Many people will find such records tiring to listen to using
earphones and no crossfeed effect.
Crossfeed has the following settings:
Crossfeed. Selects whether the crossfeed effect is to be enabled or not.
Direct Gain. How much the level of the audio that travels the direct path from a speaker
to the corresponding ear is supposed to be decreased.
Cross Gain. How much the level of the audio that travels the cross path from a speaker
to the opposite ear is to be decreased.
High-Frequency Attenuation. How much the upper frequencies of the cross path audio
will be dampened. Note that the total level of the higher frequencies will be a
combination of both this setting and the Cross Gain setting.
High-Frequency Cutoff. Decides at which frequency the cross path audio will start to
be cut by the amount described by the High-Frequency Attenuation setting.
The Rockbox manual

Most users will find the default settings to yield satisfactory results, but for the more
adventurous user the settings can be fine-tuned to provide a virtual speaker placement
suited to ones preference. Beware that the crossfeed function is capable of making the
audio distort if you choose settings which result in a too high output level.
6.9. Equalizer
Figure 6.2.: The graphical equalizer
Rockbox features a parametric equalizer (EQ). In contrast to non-parametric equalizers,
a parametric EQ enables adjusting the center frequency, gain, and width of EQ bands
separately. The ability to adjust the frequency and width of bands enables more precise
control of the EQ frequency response while avoiding the use of a large number of bands
(often 12+) needed in a non-parametric EQ.
The graphic below illustrates how the width of 10kHz band can be adjusted to cover
a wider (lower Q) or narrower (higher Q) range of frequencies.
In some ways the EQ is similar to the Bass and Treble settings described earlier, but
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
51
Chapter 6. Sound Settings
the EQ allows you to control the sound much more carefully. Note that the parameteric
EQ bands will be applied in addition to any bass or treble tone controls.
Note: A maximum of 10 EQ bands are possible on most devices, but using more than
are required will waste battery and introduce additional rounding noise. For best results,
use the fewest number of bands required.
Rockbox’s parametric EQ is composed of up to ten different bands:
Band 0: Low shelf filter. The low shelf filter boosts or lowers all frequencies below a
certain frequency limit, much as the “bass” control found on ordinary stereo systems does. Adjust the “cutoff” frequency parameter to decide where the shelving
starts to take effect. For example, a cutoff frequency of 50 Hz will adjust only very
low frequencies. A cutoff frequency of 200 Hz, on the other hand, will adjust a
much wider range of bass frequencies. The “gain” parameter controls how much
the loudness of the band is adjusted. Positive numbers make the EQ band louder,
while negative numbers make that EQ band quieter. The “Q” parameter should
always be set to 0.7 for the shelving filters. Higher values will add a small boost
around the cutoff frequency that is almost always undesirable.
Bands 1-8: Peaking filters. Peaking EQ filters boost or lower a frequency range centered at the centre frequency chosen. Graphic equalizers in home stereos are usually
peaking filters. The peaking filters in Rockbox’s EQ lets you adjust three different
parameters for EQ bands 1 through 8. The “centre” parameter controls the centre
frequency of the frequency range that is affected as described above. The “gain”
parameter controls how much each band is adjusted, and works as for the low shelf
filter. Finally, the “Q” parameter controls how wide or narrow the affected frequency range is. Higher Q values will affect a narrower band of frequencies, while
lower Q values will affect a wider band of frequencies.
Band 9: High shelf filter. A high shelf filter boosts or lowers all frequencies above a
certain frequency limit, much as the “treble” control found on ordinary stereo
systems does. The high shelf filter is adjusted the same way as the low shelf filter,
except that it works on the high end of the frequency spectrum rather than the
low end.
As a general guide, EQ band 0 should be used for low frequencies, EQ bands 1 through
8 should be used for mids, and EQ band 9 should be used for highs.
Enable EQ. This option controls whether the EQ is on or off.
Graphical EQ. This option brings up a graphic EQ screen, which allows adjustment of
each of the three parameters described above (gain, centre frequency, and Q) for
each of the five EQ bands.

Pre-cut. If too much positive gain is added through the graphical EQ, your music may
distort. The Precut setting allows you to apply a global negative gain to decoded
audio, cancelling out positive gain from the EQ. This will prevent distortion when
boosting certain frequency ranges, at the expense of making audio quieter.
Alternatively, precut can be used with a flat EQ curve to implement a volume cap.
For example, on a player that allows overdriving the headphone output to +6dB,
maximum volume can be capped to +0dB by applying 6dB of precut. Note that
precut is not applied if EQ is disabled.
Simple EQ. This option provides an easier alternative for those who are daunted by all
of the parameters that can be adjusted using the graphical EQ. With the Simple
EQ, the only parameter that can be adjusted is the gain.

operation of a parametric EQ may wish to use the presets instead of trying to

6.10. Dithering
This setting controls the dithering and noise shaping functionality of Rockbox.
Most of Rockbox’ audio file decoders work at a higher bit depth than the 16 bits used
for output on the player’s audio connectors. The simplest way to convert from one bit
depth to another is simply discarding all the surplus bits. This is the default behaviour,
and adds distortion to the signal that will vary in character along with the desired sound.
Dithering adds low-level noise to the signal prior to throwing away the surplus bits,
which gives the resulting signal a uniform noise floor which is independent of the sig-
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
Chapter 6. Sound Settings
53
nal. Most people find this noise preferable to the time-varying noise heard when not
performing dithering.
After dithering, noise shaping is performed. This basically just pushes the dithering
noise to the parts of the frequency spectrum humans cannot hear so easily. In Rockbox’
case, some of the noise is pushed up to above 10 kHz.
This setting will be put to its best use when listening to dynamic music with frequently
occuring quiet parts, classical music being a typical example. It is worth noting that the
effects of dithering and noise shaping are very subtle, and not easily noticable.
Rockbox uses highpass triangular distribution noise as the dithering noise source, and
a third order noise shaper.
6.11. Timestretch
Enabling Timestretch allows you to change the playback speed without it affecting
the pitch of the recording. After enabling this feature and rebooting, you can access
this via the Pitch Screen. This function is intended for speech playback and may
significantly dilute your listening experience with more complex audio. See section 4.3.3
(page 34) for more details about how to use the feature.
6.12. Compressor
The Compressor reduces, or compresses, the dynamic range of the audio signal. This
makes the quieter and louder sections closer to the same volume level by progressively
reducing the gain of louder signals. When subsequently amplified, this has the effect of
making the quieter sections louder while keeping the louder sections from clipping. This
allows listening to the quiet sections of dynamic material in noisy environments while
preventing sudden loud sections from being overbearing.
There are several settings associated with the compressor. The first, and most important, is the Threshold. The threshold is the audio input level at which the compressor
begins to act. Any level louder than the threshold will be compressed to some extent.
The maximum amount of compression, or the quietest level at which the compressor will
operate, is -24 dB. The default of Off disables the compressor.
The Makeup Gain setting has two options: Off and Auto. Off means that the
compressed audio will not be amplified after compression. The default of Auto will
amplify the signal so that the loudest possible signal after compression will be just
under the clipping limit. This is desirable because the compressed signal without makeup
gain is quieter than the input signal. Makeup Gain in Auto restores the signal to the
maximum possible level and brings the quieter audio up with it. This is what makes it
possible to hear the quieter audio in noisy environments.
The Ratio setting determines how aggressively the compressor reduces gain above
the threshold. For example, the 2:1 setting means that for each two decibels of input
signal above the threshold, the compressor will only allow the output to appear as one
decibel. The higher the ratio, the harder the signal is compressed. The ratio setting of
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
Chapter 6. Sound Settings
54
Limit means essentially a ratio of infinity to one. In this case, the output signal is not
allowed to exceed the threshold at all.
The Knee setting determines how abrupt the transition is from a non-compressed
signal to a compressed signal. Hard Knee means that the transition occurs precisely at
the threshold. The Soft Knee setting smoothes the transition from plus or minus three
decibels around the threshold.
The Attack Time setting sets the delay in milliseconds between the input signal
exceeding the activation threshold and acting upon it.
The Release Time setting sets the recovery time after the signal is compressed. Once
the compressor determines that compression is necessary, the input signal is reduced
appropriately, but the gain isn’t allowed to immediately return to normal levels. This is
necessary to reduce artifacts such as “pumping.” Instead, the gain is allowed to return
to normal at the chosen rate. Release Time is the time for the gain to recover by 10 dB.

7.1. Shuffle
Turning shuffle on will cause Rockbox to randomly re-order the playlist. Thus, to shuffle
all of the audio files on the player, you first need to create a playlist containing all of
them. For more information on creating playlists refer to section 4.4 (page 35).
Options: Yes/No.
7.2. Repeat
Configures settings related to repeating of directories or playlists.
Options: Off / All / One / Shuffle / A-B:
Off. The current playlist will not repeat when it is finished.
Note: If you have the Auto-Change Directory option set to Yes, Rockbox
will move on to the next directory on your hard drive. If the Auto-Change
Directory option is set to No, playback will stop when the current directory or
playlist is finished.
All. The current playlist will repeat when it is finished.
One. Repeat one track over and over.
Shuffle. When the current playlist has finished playing, it will be shuffled and then
repeated.
A-B. Repeats between two user defined points within a track, typically used by musicians when attempting to learn a piece of music. This option is more complicated
to use than the others as the player must first be placed into A-B repeat mode and
then the start and end points defined.
To set the Start Point (A) press Play + Left. Setting the End Point (B) is done

Rockbox has trouble reading from the disk. This can happen if the player is knocked,
shaken or jogged heavily while Rockbox is trying to read the hard drive.
The anti-skip buffer can be set to various values between 5 seconds and 10 minutes.
Note: Having a large anti-skip buffer tends to use more power, and may reduce your
battery life. It is recommended to always use the lowest possible setting that allows
correct and continuous playback.
7.6. Fade on Stop/Pause
Enables and disables a fade effect when you pause or stop playing a song. If the Fade
on Stop/Pause option is set to Yes, your music will fade out when you stop or pause
playback, and fade in when you resume playback.
7.7. Party Mode
Enables unstoppable music playback. When new songs are selected, they are queued at
the end of the current dynamic playlist instead of being played immediately. Pausing
and stopping playback is disabled as well as skipping songs and launching plugins.
7.8. Crossfade
This section controls the behavior of the crossfader. The crossfader, when enabled,
smoothly fades one track into the next. This can occur in two situations: an automatic
track change or a manual track skip. An automatic track change occurs at the end of

the track, moving to the next track in the playlist without user intervention. A manual track skip goes to the next track immediately when the appropriate button is pressed.
Options for crossfade settings are:
Enable Crossfade. If set to Off, crossfade is disabled and all track changes are gapless.
If set to Automatic Track Change Only, crossfade occurs for automatic track
changes, but not for manual track skips. The next setting, Manual Track Skip
Only, is the opposite: tracks will only crossfade when manually skipped. If set to
Shuffle, crossfade is enabled for all track changes, automatic or manual, when
the shuffle feature is set to Yes, but disabled otherwise. If set to Shuffle or
Manual Track Skip then crossfade will be active either when shuffle is set to
Yes or the track is manually skipped. If set to Always, tracks will always crossfade
into one another.
Fade In Delay. The “fade in delay” is the length of time between when the crossfade
process begins and when the new track begins to fade in.
Fade In Duration. The length of time, in seconds, that it takes your music to fade in
once the Fade In Delay has ended.
Fade Out Delay. The “fade out delay” is the length of time between when the crossfade
process begins and when the old track begins to fade out.
Fade Out Duration. The length of time, in seconds, that it takes your music to fade
out once the Fade Out Delay has ended.
Fade Out Mode. If set to Crossfade, one song will fade out and the next song will
simultaneously fade in. If set to Mix, the ending song will not fade out at all, and
will continue to play as normal until its end with the starting song fading in from
under it. Mix mode is not used for manual track skips, even if it is selected here.
Note: The rules above apply except in the instance where Fade Out Delay plus Fade
Out Duration is less then Fade In Delay (which would create a gap in the audio).
In this case, the Fade In Delay is reduced to eliminate the gap.
The graphic below illustrates how the different settings work in practice.

7.9. Replaygain
This allows you to control the replaygain function. The purpose of replaygain is to
adjust the volume of the music played so that all songs (or albums, depending on your
settings) have the same apparent volume. This prevents sudden changes in volume when
changing between songs recorded at different volume levels. For replaygain to work, the
songs must have been processed by a program that adds replaygain information to the
ID3 tags (or Vorbis tags).
Options for replaygain are:
Replaygain Type. Choose the type of replaygain to apply:
Album Gain. Maintain a constant volume level between albums, but keep any
intentional volume variations between songs in an album. (If album gain
value is not available, uses track gain information).
Track Gain. Maintain a constant volume level between tracks. If track gain value
is not available, no replaygain is applied.
Track Gain If Shuffling. Maintains a constant volume between tracks if Shuffle
is set to Yes. Reverts to album mode if Shuffle is set to No.
Off. Do not process replaygain information, i.e. turn off the replaygain function.
Prevent Clipping. Avoid clipping of a song’s waveform. If a song would clip during
playback, the volume is lowered for that song. Replaygain information is needed
for this to work.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
Chapter 7. Playback Settings

Pre-amp. This allows you to adjust the volume when replaygain is applied. Replaygain
often lowers the volume, sometimes quite much, so here you can compensate for
that. Please note that a (large) positive pre-amp setting can cause clipping, unless
prevent clipping is enabled. The pre-amp can be set to any decibel (dB) value
between -12 dB and +12 dB, in increments of 0.5 dB.
7.10. Track Skip Beep
Controls the volume of the beep that is heard when skipping forward or backward between tracks. The beep is disabled when set to Off.
7.11. Auto-Change Directory
Control what Rockbox does when it reaches the end of a directory. If Auto-Change Directory is set to Yes, Rockbox will continue to the next directory. If Auto-Change
Directory is set to No, playback will stop at the end of the current playlist. Using
the Random feature requires you to first generate a folder list via the Random Folder
Advance Configuration plugin (see section 12.4.15 (page 150)).
Note: You must have the Repeat option set to No for Auto-Change Directory to
function properly.
b
Note: This feature only works when songs have been played from the file browser. Using
it with the database may cause unexpected behaviour.
b
7.12. Constrain Auto-Change
If enabled and you have set Start File Browser Here to a directory other than root,
Auto-Change Directory will be constrained to the directory you have chosen and
those below it. See section 4.1.2 (page 25).
7.13. Last.fm Log
Enables logging of your played tracks for submittal to http://www.last.fm. This service
was formerly known as Audioscrobbler. When you enable this option, you’ll have to
reboot to start the logging. The log-file is called .scrobbler.log,and is to be found in
the root directory of your player.
Note: See ZLastFMLog for a further description, and for tools you can use to submit
your Last.fm log.

7.14. Cuesheet Support
Enables reading of cuesheet files for played tracks. If a cuesheet is found for a track,
track markers are displayed on the progressbar and it is possible to skip between the
tracks within the cuesheet. Also the information found in the cuesheet file will replace
the information from the ID3 tags. When you enable this option, you’ll have to reboot
for it to come into effect.
Cuesheet files should have the same file name as the audio file they reference, except
with the extension .cue. This file can either reside in the same directory as the audio
file (checked first), or within the .rockbox/cue directory.
The contents of a cuesheet file can also be embedded within the metadata of an audio
file. There is currently support for the FLAC tag/ Vorbis comment CUESHEET or the
ID3v2 TXXX CUESHEET tag.
7.15. Skip Length
Designed to speed up navigation when listening to long audio tracks, Skip Length
changes the behaviour of the Rewind and Forward buttons so that they skip by a
given time instead of skipping to a new track. The Skip to Outro option changes the
behaviour so that the buttons skip to just before the end of the track, so that the last
few seconds are played before the next track.
7.16. Prevent Track Skipping
If this option is enabled, the ability to manually skip tracks is disabled in order to avoid
accidental track skips. It does not prevent changing tracks if a track ends, which can be
achieved by combining this option with Repeat set to One
7.17. Rewind Before Resume
When restarting a track or a bookmark, a short rewind can be done before the playback
is started. This can be useful when listening to speech material, to help remember what
was being said just before playback was stopped. The size of the rewind can be set to
various values between 0 (off) and 60 seconds.
Note: This option does not apply to resuming a paused track. Use the next option for
rewinding on pause.
Note: The actual rewind distance may differ a little from the requested value, depending
on the file in question.

7.18. Rewind on Pause
This option rewinds the current track by a small amount whenever it is paused (not
stopped). The amount to rewind can be set between 0 and 15 seconds.
7.19. Frequency
This is the sampling frequency used for the rockbox playback engine. Audio at a different
sampling rate will be converted to this sampling rate prior to mixing using a cubic
Hermite polynomial resampler.
Note: For best quality and battery life, select the sampling rate used by your audio.
This is typically 44.1kHz.
Note: Opus files are always 48kHz.

Recursively Insert Directories. If set to On, then when a directory is inserted or queued
into a dynamic playlist, all subdirectories will also be inserted. If set to Ask,
Rockbox will prompt the user about whether to include sub-directories.
Warn When Erasing Dynamic Playlist. If set to Yes, Rockbox will provide a warning
if the user attempts to take an action that will cause Rockbox to erase the current
dynamic playlist.
8.2. File View
The File View menu deals with options relating to how the File Browser displays files.
Sort Case Sensitive. If this option is set to Yes, all files that start with upper case
letters will be listed first, followed by all files that begin with lower case letters. If
this option is set to NO, then case will be ignored when sorting files.
Sort Directories. This option controls how Rockbox sorts directories. The default is to
sort them alphabetically. By date sorts them with the oldest directory first. By
newest date sorts them with the newest directory first.
Sort Files. This option controls how Rockbox sorts files. All of the options for Sort
Directories are available in this option. In addition, there is a By type option
which sorts files alphabetically by their type (such as .mp3) then alphabetically
within each type.

Interpret numbers when sorting. As whole numbers enables a sorting algorithm which
is similar to the default sorting of, for example, Windows Explorer, Mac OS X’s
Finder or Nautilus, with regards to numbers at the beginning or within filenames.
It combines consecutive digits to a number used for sorting, taking leading zeros
into account.
As digits disables this algorithm, and causes every digit to be compared separately. The following table demonstrates the two sorting methods.

Show Files. This option controls which files are displayed in the File Browser.
All. The File Browser displays all files and directories. Extensions are shown.
No files or directories are hidden.
Supported. The File Browser displays all directories and files supported by
Rockbox (see section A.1 (page 172)). Files and directories starting with .
(dot) or with the hidden flag set are hidden.
Music. The File Browser displays only directories, playlists and the supported
audio file formats. Extensions are stripped. Files and directories starting
with . or with the “hidden” flag set are hidden.
Playlists. The File Browser displays only directories and playlists, for simplified
navigation.
Show Filename Extensions. This option controls how file extensions are shown in the
File Browser.
Off. The file extensions are never shown.
On. The file extensions are always shown.
Only unknown types. Only the extensions of unknown filetypes are shown.
Only when viewing all types. Only show file extensions when Show Files is set
to All.
Follow Playlist. This option determines what directory the File Browser displays
first. If Follow Playlist is set to Yes, when you enter the File Browser from
the WPS, you will find yourself in the same directory as the currently playing file.

File Browser.
Show Path. If this setting is set to Full Path the full path to the current directory
will be displayed on the first line in the File Browser. If set to Current
Directory Only only the name of the current directory will be displayed.
This has a similar effect on the Database browser. If set to Current Directory
Only or Full Path, then the title of each menu will be displayed on the first line
in the Database Browser.
8.3. Database
This sub menu allows you to configure the database. See section 4.2 (page 27) for more
information about using the database.
8.4. Display
LCD Settings. This sub menu contains settings that relate to the display of the player.
Backlight. The amount of time the backlight shines after a key press. If set to
Off, the backlight will not light when a button is pressed. If set to On, the
backlight will never shut off. If set to a time (1 to 90 seconds), the backlight
will stay lit for that amount of time after a button press.
Backlight (While Plugged In). This setting is equivalent to the Backlight setting except it applies when the player is plugged into the charger.
Backlight on Hold. This setting controls the behavior of the backlight when the
Hold switch is toggled. If set to Normal the backlight will behave as usual.
If set to Off the backlight will be turned off immediately when the Hold
switch is engaged and if set to On the backlight will be turned on and stay
on while the Hold switch is engaged.
Caption Backlight. This option turns on the backlight a number of seconds before
the start of a new track, and keeps it on for the same number of seconds after
the beginning so that the display can be read to see song information. The
amount of time is determined by the value of the backlight timeout setting,
but is no less than 5 seconds.
First Keypress Enables Backlight Only. With this option enabled the first keypress while the backlight is turned off will only turn the backlight on without
having any other effect. When disabled the first keypress will also perform
its appropriate action.
Contrast. Changes the contrast of your LCD display.

LCD Mode. This setting lets you invert the colours of the display.
Scrolling. This feature controls how text will scroll in Rockbox. You can configure the
following parameters:
Scroll Speed. Sets how many times per second the automatic horizontal scrolling
text will move a step.
Scroll Start Delay. Controls how many milliseconds Rockbox should wait before
a new text begins automatically scrolling.
Scroll Step Size. Defines the number of pixels the text should move for each step,
as used by the Scroll Speed setting.
Bidirectional Scroll Limit. Rockbox has two different automatic horizontal scrolling
methods: 1) always scrolling the text to the left until the line has ended and
then beginning again at the start, and 2) moving to the left until you can
read the end of the line and then scrolling right until you see the beginning
again. Rockbox chooses which method it should use depending of how much
it has to scroll to the left. This setting lets you tell Rockbox where that limit
is, expressed in percentage of the line length.
Screen Scrolls Out of View. Screens can be manually scrolled horizontally by
pressing Long Right/Left. Setting this option to Yes will keep the list
entries at their fixed positions and allow them to be scrolled out of view,
whereas No will only scroll those entries which surpass the right margin.
Screen Scroll Step Size. Defines the number of pixels the horizontal manual screen
scroll should move for each step.
Paged Scrolling. When set to Yes scrolling vertically on pages that surpass the
screen size will page up/down instead of simply changing lines. This can be
useful on slow displays.
List Acceleration Start Delay. This setting enables the acceleration of scroll speed
in lists when holding Up or Down. When set to Off the acceleration is
disabled. When any other value is set the acceleration will start to accelerate
after holding Up or Down for the chosen time (in seconds).
List Acceleration Speed. This setting controls how fast the scroll speed accelerates. The scroll speed will increase every N seconds. For example, selecting
Speed up every 3s will increase the scroll speed every 3 seconds while Up
or Down is held.
Peak Meter. The peak meter can be configured with a number of parameters.
Peak Release. This determines how fast the bar shrinks when the music becomes
softer. Lower values make the peak meter look smoother. Expressed in scale
units per 10 ms.

Peak Hold Time. Specifies the time after which the peak indicator will reset. For
example, if you set this value to 5 s, the peak indicator displays the loudest
volume value that occurred within the last 5 seconds. Larger values are useful
if you want to find the peak level of a song, which might be of interest when
copying music from the player via the analogue output to some other recording
device.
Clip Hold Time. The number of seconds that the clipping indicator will be visible
after clipping is detected.
Clip Counter. Show the number of times the clip indicator went active during
recording in front of the peak meters.
Scale. Select whether the peak meter displays linear or logarithmic values. The
human ear perceives loudness on a logarithmic scale. If the Scale setting is
set to Logarithmic (dB) scale, the volume values are scaled logarithmically.
The volume meters of digital audio devices usually are scaled this way. On
the other hand, if you are interested in the power level that is applied to
your headphones you should choose Linear display. This setting cannot
be displayed in units like volts or watts because such units depend on your
headphones.
Minimum and maximum range. These two options define the full value range
that the peak meter displays. Recommended values for the Logarithmic
(dB) setting are -40 dB for minimum and 0 dB for maximum. Recommended
values for Linear display are 0 and 100%. Note that -40 dB is approximately 1% in linear value, but if you change the minimum setting in linear
mode slightly and then change to the dB scale, there will be a large change.
You can use these values for ‘zooming’ into the peak meter.
Default Codepage. A codepage describes the way extended characters that are not
available within the ASCII character set are encoded. ID3v1 tags do not have a
codepage encoding contained so Rockbox needs to know what encoding has been
used when generating these tags. This should be “ISO-8859-1” but to support languages outside Western Europe most applications use the setting of your operating
system instead. If your operating system uses a different codepage and you are
getting garbled extended characters you should adjust this settings. In most cases
sticking to “ISO-8859-1” would be sufficient.
8.5. System
8.5.1. Battery
Options relating to the battery in the player.
Battery Capacity. This setting can be used to tell Rockbox what capacity (in mAh) the
battery being used has. The default is 650 mAh, which is the capacity value for

the standard battery shipped with the player. Rockbox uses this value for runtime
estimation, not battery percentage calculation. Changing this setting has no effect
whatsoever on actual battery life. This setting only affects the accuracy of the
runtime estimation as shown on screen.
8.5.2. Disk
Options relating to the hard disk.
Disk Spindown. Rockbox has a timer that makes it spin down the hard disk after it is
idle for a certain amount of time. This setting controls the amount of time between
the last user activity and the time that the disk spins down. This idle time is only
affected by user activity, like navigating through the File Browser. When the
hard disk spins up to fill the audio buffer, it automatically spins down afterwards.
Directory Cache. Rockbox has the ability to cache the contents of your drive in RAM.
The Directory Cache takes a small amount of memory away from Rockbox
that would otherwise be used to buffer music, but it speeds up navigation in the
file browser by eliminating the slight pause between the time a navigation button
is pressed and the time Rockbox responds. Turning this setting on activates the
directory cache, and turning it off deactivates the directory cache.
Note: The first time you enable the directory cache, Rockbox will request a reboot
of the player and upon restarting take a few minutes to scan the drive. After this,
the directory cache will work in the background.
8.5.3. Limits
This sub menu relates to limits in the Rockbox operating system.
Max Entries in File Browser. This setting controls the limit on the number of files that
you can see in any particular directory in the file browser. You can configure the
size to be between 50 and 10,000 files in steps of 50. The default is 400. Higher
values will shorten the music buffer, so you should increase this setting only if you
have directories with a large number of files.
Max Playlist Size. This setting controls the maximum size of a playlist. The playlist
size can be between 1,000 and 32,000 files, in steps of 1,000 (default is 10,000).
Higher values will shorten the music buffer, so you should increase this setting only
if you have very large playlists.
Glyphs To Cache. This sets the default memory allocation size for fonts in unique
glyphs. This should be set to the number of unique language glyphs and punctuation marks that are frequently displayed. The default is 250.

8.5.4. Use Shortcuts Menu Instead of Quick Screen
This option activates the shortcuts menu instead of opening the quick screen when
enabled.
8.5.5. Keyclick
This menu controls key clicks on button presses.
Keyclick. This setting controls how strong the keyclicks are. If set to Off, the keyclicks

Keyclick repeats. This setting turns keyclick repeats On and Off. If set to On, the
keyclicks will be repeated when you hold down a button. If set to Off, you will
hear only one click.
8.5.6. USB HID
This option turns the USB HID feature On and Off. When this feature is enabled, the
player enumerates as a Human Interface Device (HID), composed of several HID sub
devices. Since the player also enumerates as a Mass Storage Device, it becomes a USB
Composite Device, which contains both these devices.
8.5.7. USB Keypad Mode
This setting control the keypad mode when the player is attached to a computer through
USB. Pressing a key on the player sends a keystroke the computer the player is attached
to, according to the mapping set by the keypad mode. There are different modes which
provide different functionality. Switching modes back and forth is done by pressing the
Rec+Rewind and Rec+Forward keys, respectively.
The following modes are available:

Restart Sleep Timer On Keypress: If set, when a Sleep Timer is active and a key is
pressed, the Sleep Timer will be restarted with the initial duration.
8.7. Bookmarking
Bookmarks allow you to save your current position within a track so that you can return
to it at a later time. Bookmarks also store rate, pitch and speed information from the
Pitch Screen (see section 4.3.3 (page 34)). Bookmarks are saved on a per directory

basis or for individual (saved) playlists. You can store multiple bookmarks, even for the
same track. When there’s already a bookmark for a directory or playlist, new bookmarks
are added before existing ones.
Bookmarks are stored next to the directory or playlist they reference, in a file with the
same name as the directory or playlist and a “.bmark” extension. To load a bookmark,
select the bookmark file and then select the bookmark to load. There are other ways to
load a bookmarks mentioned below.
Note: Bookmarking only works when tracks are launched from the file browser, and
does not work for tracks launched via the database. In addition, they do not work with
dynamic playlists.
b
Bookmark on Stop. This option controls whether Rockbox creates a bookmark when
playback is stopped manually.
No. Do not create bookmarks.
Yes. Always create bookmarks.
Ask. Ask if a bookmark should be created.
Yes – Recent Only. Always create a bookmark, but only in the recent bookmarks
list.
Ask – Recent Only. Ask if a bookmark should be created, but only add it to the
recent bookmarks list.
When either Yes – Recent Only or Ask – Recent Only is selected, bookmarks
are only created if the Maintain a List of Recent Bookmarks is enabled.
Note: The Resume function remembers your position in the most recently accessed track regardless of how the Bookmark on Stop option is set.
Update on Stop. If set to “No”, this setting has no effect and does not affect any other
settings. If set to “Yes”, and the file to which a new bookmark would be added
already exists, this option overrides the previous setting (Bookmark on Stop)
and unconditionally creates a bookmark. This is useful if you don’t generally want
to create bookmarks but only want to add them to already existing bookmark

8.8. Automatic resume
The automatic resume feature stores and recalls resume positions for all tracks without
user intervention. These resume points are stored in the database, and thus automatic
resume only works when the database has been initialized.
When automatic resume is enabled, manually selected tracks resume playback at their
last playback position. It does not matter in which way you start the track; tracks are
resumed whether they are navigated to through the database browser or file browser,
by starting a playlist, or by skipping through tracks in the current playlist. (As an
exception, when a track is resumed by loading a bookmark, the playback position saved
in the bookmark takes precedence.)
Optionally, you can also enable automatic resume for automatic track transitions.
In this case, the next track will be resumed as well instead of starting playback at its
beginning. This is most useful for podcasts, and can be enabled on a per-directory basis.

A track’s resume position is updated whenever playback of that track stops, including
when explicitly stopping the track, powering off the player, or starting playback of
another track.
If you intend to start a track from its beginning but notice that it was resumed, you
can press Rewind in the WPS to skip back to its beginning. When pressing Rewind
again in the first few seconds of a track to go to the previous track, the previously
(on first button press) saved resume position is retained. Therefore, you can also use
Rewind and Forward to skip across tracks in a playlist without losing their resume
position.
Automatic resume. This option enables or disables automatic resume globally. When
Rockbox detects that the database (which is needed for this feature) has not been
initialized yet, it asks whether it should be initialized right away.
Resume on automatic track change. Controls whether the next track in an automatic
track transition should be resumed at its last playback position as well.
No. Automatic resume works only for manual track selection.
Yes. Always attempt to resume – for both manual and automatic track changes.
In custom directories only. Configure directories in which to enable resume on
automatic track change. Selecting this option starts the text editor, in which
you can enter the (absolute, case-insensitive) directory names separated by
colons (“:”).
A typical value is “/podcast”, which matches all files in directories /PODCAST,
/Podcast or /podcast and their subdirectories, but not in directories /podcasts
(mind the trailing “s”) or /audio/podcast.
8.9. Language
This setting controls the language of the Rockbox user interface. Selecting a language
will activate it. The language files must be in the /.rockbox/langs/ directory. See
section 13.1.4 (page 158) for further details about languages.
8.10. Voice
Voice Menus. This option controls the voicing of menus/settings as they are selected
by the cursor. In order for this to work, a voice file must be present in the
/.rockbox/langs/ directory on the player. Voice files are large and are not
shipped with Rockbox by default. The voice file is the name of the language
for which it is made, followed by the extension .voice. So for English, the file
name would be english.voice. This option is on by default, but will do nothing
unless the appropriate voice file is installed in the correct place on the player. The
Voice Menus have several limitations:

Chapter 8. General Settings
• Setting the Sound Option Channels to Karaoke may disable voice menus.
• Plugins and the wake up alarm do not support voice features.
Voice Directories. This option controls voicing of directory names. A voice file must be
present for this to work. Several options are available.
Spell. Speak the directory name by spelling it out letter by letter. Support is
provided only for the most common letters, numbers and punctuation.
Numbers. Each directory is assigned a number based upon its position in the file
list. They are then announced as “Directory 1”, “Directory 2” etc.
Off. No attempt will be made to speak directory names.
You can use pre-generated .talk clips to have directory names spoken properly, but
you must enable this explicitly (see below).
Use Directory .talk Clips. This option turns on the use of .talk clips for directories.
On. Use special pre-recorded files (_dirname.talk) in each directory. These must
be generated in advance, and are typically produced synthetically using a
text-to-speech engine on a PC.
Off. No checking is made for directory .talk clips; they are not used even if present.
This can reduce disk activity.
Use of a .talk clip takes precedence over other directory name voicing. Otherwise
(e.g. if a .talk clip is not available), voicing uses the method set under Voice
Directories above.
Voice Filenames. This option controls voicing of filenames. Again, a voice file must be
present for this to work. The options provided are Spell, Numbers, and Off
which function the same as for Voice Directories. You can use pre-generated
.talk clips to have filenames spoken properly, but you must enable this explicitly
(see below).
Use File .talk Clips. This option turns on the use of .talk clips for files.
On. Use special pre-recorded files for each file. This functions the same as for
directories except that the .talk clip file must have the same name as the
described file with an extra .talk extension (e.g. Punkadiddle.mp3 would
require a file called Punkadiddle.mp3.talk).
Off. No checking is made for file .talk clips; they are not used even if present. This
can reduce disk activity.
Use of a .talk clip takes precedence over other filename voicing. Otherwise (e.g. if
a .talk clip is not available), voicing uses the method set under Voice Filenames
above.
Say File Type. This option turns on voicing of file types when Voice Filenames is set
to Spell or Numbers. When Voice Directories is set to Spell, “Directory”
will be voiced after each spelled out directory.

Note: Themes do not have to be purely visual. It is quite possible to create a theme
that switches between audio configurations for use in the car, with headphones and
when connected to an external amplifier. See section 13.2.2 (page 160) for more
details.
Font. Browse the installed fonts on your player. Selecting one will activate it. See
section 13.1.3 (page 157) for further details about fonts.
While Playing Screen. Opens the File Browser in the /.rockbox/wps directory and
displays all .wps files. Selecting one will activate it, Left or Long Left will exit
back to the menu. For further information about the WPS see section 4.3 (page 30).

Options: Off, Main unit only, Main and remote unit, Remote unit only.
10.11. Trigger
When you record a source you often are only interested in the sound and not the silence
in between. The recording trigger provides you with a tool to automatically distinguish
between sound and silence and record the sound only. Unfortunately it is not very easy
to make this distinction between silence and sound because you hardly ever encounter
real silence. There always are background noises. What is considered as background
noise depends on the situation. For example during a lecture the very low noise of
rustling paper might be considered as background noise. During a rock concert the
murmur of the audience might be considered background noise which is much louder
compared to rustling paper. Also the duration of the signal matters. When you record
speech you want to record every syllable. When you record live music you may not be
interested in that chord the guitarist plays for two minutes before the show to verify his
amp is turned on. The trigger features numerous parameters to adapt its behaviour to
the desired situation.
Trigger. This parameter specifies the trigger mode. When set to Off the recording must
be started manually and apart from the Prerecord time no other parameter has
any effect. Once will have the trigger start one recording only; after the recording
has finished the input signal will not start another recording. Repeat will have
the trigger start multiple recordings.
Trigtype. Add description of Trigtype Options: Stop, Pause, New File.
Prerecord Time. This specifies the time that is included into the recording before the
trigger event occurs. This is very useful if you record a signal that fades in. Usually
you want to set the prerecord time greater than or equal to the start duration. That
ensures that you record the entire sound. Strictly speaking the prerecord time is
not a special parameter of the trigger. It is available during normal recordings too.
Start Above. The start threshold defines the minimal volume a sound must have to start
the recording. It is displayed numerically in the line “Start Above”. Note that the
unit of the threshold depends on the settings of the peak meter. (i.e. When the
peak meter displays dB you can adjust the level in dB and when the peak meter
is set to linear the threshold is displayed as percentage.) In the peak meter at the
bottom of the screen the start threshold is displayed graphically by a little triangle

Chapter 10. Recording Settings

pointing to the right. There are two special values. The value Off turns the start
condition off. With this setting you have to start the recording manually and the
trigger only stops the recording according to the stop condition. The setting -inf
sets the trigger to the absolute minimum. This setting only makes sense when you
record via a digital input as even the noise of the device itself would exceed this
threshold immediately.
for at least. The start duration defines the minimal duration that a signal must exceed the start threshold to start the recording. Depending on your situation you
may want to set this setting to 0 (e.g. when copying a song from a commercial
medium) or to quite big values. Because sound is not continuous by nature (think
of percussion) negligible dropouts are tolerated during this start duration.
Stop Below. When the sound level drops below the stop threshold the recording is
stopped. It is displayed numerically in the line “Stop Below”. Just like the start
threshold the unit of the stop threshold depends on the settings of the peak meter.
There’s also a small triangular marker in the peak meter at the bottom of the
screen. In contrast to the start threshold marker it points to the left. The value
Off turns the stop condition off. With this setting you have to stop the recording
manually.
for at least. This time specifies the duration the signal must drop below the stop threshold to stop the recording. By selecting high values you can ensure that, for example,
trailing fade-outs are recorded entirely.
Presplit Gap. When the signal drops below the stop threshold for the time specified by
the presplit gap a new recording may be started when the signal raises above the
start threshold. Thus the value of the presplit gap should be smaller than the stop
hold time. Otherwise the recording would stop anyway and the presplit gap has
no effect. For most uses I recommend to set this parameter equal to the stop hold
time. Sometimes you may encounter a sound source (e.g. a CD) where the songs
have fade outs and hardly any gaps between the tracks. Here you can set the stop
hold time to long values to ensure that all fade outs are recorded completely. By
specifying a short presplit gap you still can split the recording into separate tracks
whenever the trigger start condition is met.

Plugins are programs that Rockbox can load and run. Only one plugin can be loaded at
a time. Plugins have exclusive control over the user interface. This means you cannot
switch back and forth between a plugin and Rockbox. When a plugin is loaded, you need
to exit it to return to the Rockbox interface. Most plugins will not interfere with music
playback but some of them will stop playback while running. Plugins have the file extension .rock. Most of them can be started from Browse Plugins in the Main Menu.
Viewer plugins get started automatically by opening an associated file (i.e. text files,
chip8 games), or from the Open with option on the Context Menu.

12.1.1. 2048
2048 is a simple, addictive puzzle game played by moving tiles in around on a 4x4 grid.
Tiles slide as far as possible in the direction chosen by the player each turn until they
are stopped by either another tile or the edge of the grid. If two tiles of the same number
collide while moving, they merge into a tile with the total value of the two tiles that
collided. The resulting tile cannot merge with another the same move. After each move,
a tile with the value of 2 or 4 is created in an empty spot on the grid.
The game is won when a tile with a value of 2048 is created, and the player loses when
there are no more possible moves.

will show the list of matches included in the file and allow you to select the one you want
to watch. After that, you can scroll back and forth through the moves of the game. If
the menu is invoked while in the viewer, the user is allowed to select a new match from
the same file or quit the game.
“Force play” while the computer is thinking will cause it to make its move immediately.
If done while it’s your turn, the computer will move for you and flip the board so that
you are playing from the other side. If you want, you can force play an entire game and
watch the artificial intelligence fight against itself.
When you quit the game the current state will be saved and restored when you resume
the game. The menu also allows the user to reload the last game saved, save the current
position and start a new game without having to quit the game.

12.1.12. Goban
Figure 12.10.: Goban
Goban is a a plugin for playing, viewing and recording games of Go (also known as
Weiqi, Baduk, Igo and Goe). It uses standard Smart Game Format (SGF) files for saving and loading games. You can find a short introduction to Go at http://senseis.xmp.
net/?WhatIsGo and more information about SGF files can be read at http://senseis.xmp.
net/?SmartGameFormat or the SGF specification at http://www.red-bean.com/sgf/.
This plugin can load all modern SGF files (file format 3 or 4) with few problems. It
attempts to preserve SGF properties which it doesn’t understand, and most common
SGF properties are handled fully. It is possible to view (and edit if you like) Kogo’s
Joseki Dictionary (http://waterfire.us/joseki.htm) with this plugin, although the load
and save times can be on the order of a minute or two on particularly slow devices.
Large SGF files may stop audio playback for the duration of the plugin’s run in order to
free up more memory and some very large SGF files will not even load on devices with
little available memory.
Note: The plugin does NOT support SGF files with multiple games in one file. These
are rare, but if you have one don’t even try it (the file will most likely be corrupted if
you save over it). You have been warned.

The file /sgf/gbn_def.sgf is used by the plugin to store any unsaved changes in
the most recently loaded game. This means that if you forget to save your changes, you
should load /sgf/gbn_def.sgf immediately to offload the changes to another file. If you
load another file first then your changes will be lost permanently. The /sgf/gbn_def.sgf

The game
Use the control keys of your worm to navigate around obstacles and find food. Worms
do not stop moving except when dead. Dead worms are no fun. Be careful as your worm
will try to eat anything that you steer it across. It won’t distinguish whether it is edible
or not.
Food. The small square hollow pieces are food. Move the worm over a food tile to eat
it. After eating the worm grows. Each time a piece of food has been eaten a new
piece of food will pop up somewhere. Unfortunately for each new piece of food
that appears two new “argh” pieces will appear, too.
Argh. An “argh” is a black square poisoned piece - slightly bigger than food - that
makes a worm say “Argh!” when run into. A worm that eats an “argh” is dead.
Thus eating an “argh” must be avoided under any circumstances. “Arghs” have
the annoying tendency to accumulate.
Worms. Thou shall not eat worms. Neither other worms nor thyself. Eating worms is
blasphemous cannibalism, not healthy and causes instant death. And it doesn’t
help anyway: the other worm isn’t hurt by the bite. It will go on creeping happily
and eat all the food you left on the table.
Walls. Don’t crash into the walls. Walls are not edible. Crashing a worm against a wall
causes it a headache it doesn’t survive.
Game over. The game is over when all worms are dead. The longest worm wins the
game.
Pause the game. Press Play to pause the game. Press it again to resume the game.
Stop the game. There are two ways to stop a running game.
• If you want to quit Wormlet entirely simply hit Rec. The game will stop
immediately and you will return to the game menu.
• If you want to stop the game and still see the screen hit Rewind. This freezes
the game. If you hit Rewind button again a new game starts with the same
configuration. To return to the games menu you can hit Rec. A stopped
game can not be resumed.
The scoreboard
On the right side of the game field is the score board. For each worm it displays its
status and its length. The top most entry displays the state of worm 1, the second worm
2 and the third worm 3. When a worm dies its entry on the score board turns black.
Len: Here the current length of the worm is displayed. When a worm is eating food it
grows by one pixel for each step it moves.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820

Chapter 12. Plugins
Hungry: That’s the normal state of a worm. Worms are always hungry and want to eat.
It is good to have a hungry worm since it means that your worm is alive. But it is
better to get your worm growing.
Growing: When a worm has eaten a piece of food it starts growing. For each step it
moves over food it can grow by one pixel. One piece of food lasts for 7 steps. After
your worm has moved 7 steps the food is used up. If another piece of food is eaten
while growing it will increase the size of the worm for another 7 steps.
Crashed: This indicates that a worm has crashed against a wall.
Argh: If the score board entry displays “Argh!” it means the worm is dead because it
tried to eat an “argh”. Until we can make the worm say “Argh!” it is your job to
say “Argh!” aloud.
Wormed: The worm tried to eat another worm or even itself. That’s why it is dead
now. Making traps for other players with a worm is a good way to get them out
of the game.
Hints
• Initially you will be busy with controlling your worm. Try to avoid other worms
and crawl far away from them. Wait until they curl up themselves and collect the
food afterwards. Don’t worry if the other worms grow longer than yours - you can
catch up after they’ve died.
• When you are more experienced watch the tactics of other worms. Those worms
controlled by artificial stupidity head straight for the nearest piece of food. Let
the other worm have its next piece of food and head for the food it would probably
want next. Try to put yourself between the opponent and that food. From now
on you can ‘control’ the other worm by blocking it. You could trap it by making
a 1 pixel wide U-turn. You also could move from food to food and make sure you
keep between your opponent and the food. So you can always reach it before your
opponent.

12.2.10. PictureFlow
Figure 12.36.: PictureFlow
PictureFlow provides a visualisation of your albums with their associated cover art. It is
possible to start playback of the selected album from PictureFlow. Playback will start
from the selected track. The PictureFlow plugin will continue to run while your tracks
are played.
Requirements
PictureFlow uses both the album art (see section C (page 179)) and database (see
section 4.2 (page 27)) features of Rockbox. It is therefore important that these are
working correctly before attempting to use PictureFlow. In addition, there are some
other points of which to be aware:
• PictureFlow will accept album art larger than the dimensions of the screen, but
the larger the dimensions, the longer they will take to scale.

12.3.1. Shortcuts
The Shortcuts Plugin allows you to jump to places within the file browser without having
to navigate there manually. The plugin works with .link files. A .link file is just a
text file with every line containing the name of the file or the directory you want to
quickly jump to. All names should be full absolute names, i.e. they should start with a
/. Directory names should also end with a /.
How to create .link files
You can use your favourite text editor to create a .link file on the PC an then copy
the file to the player. Or you can use the context menu on either a file or a directory in
the file browser tree, and use the “Add to shortcuts” menu option. This will append a
line with the full name of the file or the directory to the shortcuts.link file in the root
directory of the player. (The file will be created if it does not exist yet.) You can later
rename the automatically created shortcuts.link file or move it to another directory
if you wish. Subsequent calls of the context menu will create it again.
How to use .link files, i.e. jump to desired places
To use a .link file just “play” it from the file browser. This will show you a list with the
entries in the file. Selecting one of them will then exit the plugin and leave you within
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
123
Chapter 12. Plugins
the directory selected, or with the file selected in the file browser. You can then play
the file or do with it whatever you want. The file will not be “played” automatically.
If the .link file contains only one entry no list will be shown, you will directly jump
to that location. The file shortcuts.link in the root directory is an exception. After
“playing” it, the list will be shown even if the file contains just one entry.
If the list you are seeing is from shortcuts.link in the root directory, you can delete
the selected entry by pressing Long Left+Long Up. Deleting entries from other .link
files is not possible.
Advanced Usage
Placing the line “#Display last path segments=n” (where n is a number) in the beginning
of a .link file will leave just the last n segments of the entries when they are shown. For
example, if n is chosen to be 1, then the entry /MyMusic/collection/song.mp3 will be
shown as song.mp3. This allows you to hide common path prefixes.
You can also provide a custom display name for each entry individually. To do so,
append a tabulator character after the entry’s path followed by your custom name. That
name will then be used for showing the entry. For example:
Example
/MyMusic/collection/song.mp3<TAB>My favourite song!
12.3.2. Chip-8 Emulator
Chip8 is a kind of assembly language for a long-gone architecture. This plugin runs
games written using the chip8 instructions. To start a game open a .ch8 file in the File
Browser
There are lots of tiny Chip8 games (usually only about 256 bytes to a couple of KB)
which were made popular by the HP48 calculator’s emulator for them. The original
Chip8 had 64×32 pixel graphics, and the new superchip emulator supports 128×64
graphics.
The only problem is that they are based on a 4×4 keyboard, but since most games do
not use all of the buttons, this can easily be worked around.
To do this, one may put a .c8k file with the same name as the original program
which contains new key mappings (for BLINKY.ch8, one writes a BLINKY.c8k file). That
.c8k file contains 16 characters describing the mapping from the Chip8 keyboard to
the default key mapping (that way, several Chip8 keys can be pressed using only one
Rockbox key). For example, a file containing the single line:
Code
0122458469ABCDEF
would correspond to the following non-default mappings:
3 → 2, 6 → 8, 7 →4, 8 → 6.
The default keymappings are:

12.3.3. Frotz
Frotz is a Z-Machine interpreter for playing Infocom’s interactive fiction games, and
newer games using the same format. To start a game open a .z1 - .z8 file in the File
Browser. Most modern games are in the .z5 or .z8 format but the older formats used
by Infocom are supported.
Z-Machine games are text based and most depend heavily on typed commands. The
virtual keyboard is used for text entry, both for typing entire lines and for typing single
characters when the game requires single character input.
Sounds, pictures, colour and Unicode are not currently supported, but the interpreter
informs the game of this and almost all games will adapt so that they are still playable.
This port of Frotz attempts to be compliant with the Z-Machine Specification version
1.0.
Some places where you can find Z-Machine games, and information about interactive
fiction:
• The Interactive Fiction Archive, where many free modern works can be downloaded: http://www.ifarchive.org/
• The specific folder on the if-archive containing Z-Machine games: http://www.

• The Infocom homepage, with information about how to get the classic commercial
Infocom games: http://www.csd.uwo.ca/Infocom/

12.3.5. Lua scripting language
To quote from the Lua website (http://www.lua.org), Lua is a “powerful, fast, lightweight,

more information on programming in Lua, please see http://www.lua.org/manual/5.1/
and http://www.lua.org/pil/.
There are a few exceptions/additions to the Lua support in Rockbox:
No floating point support. The number type in Lua is usually float, however in the
Rockbox implementation it is integer.
Non-supported libraries. The coroutine, debug and math libraries are not supported.
Partially-supported libraries. The os and package libraries are only partially supported.
Additional libraries. The bitlib library is integrated to support bitwise operators. See
http://luaforge.net/projects/bitlib and http://lua-users.org/wiki/BitwiseOperators.
Documentation of the API is still a work in progress, and the API itself is not finalised.
For the latest information, see ZPluginLua.
Note: Please note that if a script does not provide a way to exit, then the only way to
exit will be to reset the player.

12.3.8. MP3 Encoder
This plugin encodes a .wav file to MP3 format. The supported input format is uncompressed, linear PCM with 16 bit per sample and a maximum of 2 channels. Allowed
sample rates are 16, 22.05, 24, 32, 44.1 and 48 kHz. The user will be asked to select the
desired output bitrate of the compressed MP3 file.
Select Bitrate The following bitrates can be selected: 64, 80, 96, 112, 128, 160, 192,
224, 256, 320 kbps.
Remark: Bitrates above 160 kbps cannot be used in MPEG 2 Layer 3 bitstreams.
The encoder plugin automatically limits the output bitrate to 160 kbps for input
files with a sample rate of 16, 22.05 or 24 kHz. The same limitation is valid for
mono files.
The output .mp3 file is written to the same path as the .wav file using the same
filename. To use this plugin, open the Context Menu (see section 4.1.2 (page 24)) on
a .wav file and select Open With. . . → mp3_encoder.
Note: The encoder will choose the appropriate bitstream format from the sample rate of
the input file. The output bitstream format is MPEG 1 Layer 3 for 32, 44.1 and 48 kHz,
and MPEG 2 Layer 3 for 16, 22.05 and 24 kHz. MPEG 2.5 Layer 3 is not supported.

Hacking graphics
Due to ZXBox’s simple (but fast) scaling to the screen by dropping lines and columns
some games can become unplayable. It is possible to hack graphics to make them better
visible with the help of an utility such as the “Spectrum Graphics Editor”. Useful tools
can be found at the “World of Spectrum” site (http://www.worldofspectrum.org/utilities.

12.4.2. Battery Benchmark
The Battery Benchmark plugin enables you to test your battery’s performance whilst
using your player normally. Results can be submitted to the ZBatteryRuntime wiki
page.

Samsung YH-820

Chapter 12. Plugins
How it works
Once loaded, Battery Benchmark runs in the background recording various information about your battery to memory. A new point is written to memory every minute.
Every time the disk is accessed for any reason (such as refilling the audio buffer, opening a directory or entering USB mode etc.) then the information in memory is written
to disk. Once the memory becomes full (after many hours), then the data are written
to disk anyway. This is done so that the data are not biased by excessive additional
disk accesses. The file is written to the root directory of your player and is called
battery_bench.txt. The plugin will continue to log info until:
• Another plugin is loaded.
• The player is shut down.
• The battery is empty.
Benchmarks can be resumed if you accidentally load a plugin, or turn off your player,
so long as the log file battery_bench.txt is not deleted.
Information explained
At the top of the battery_bench.txt file is various information on how to use the
plugin, followed by the data themselves.
Time This column reports the total time of operation of the player. It is not the time
that you started the plug-in. If you have your player on for 5 minutes and then
start the plugin, it will start measuring from 5 minutes.
Seconds The same as Time, except measured in seconds.
Level The percent level of the battery estimated by Rockbox, and not the actual battery
level. The actual battery level can be seen from the Voltage column
Time Left This shows the time remaining until the battery is empty, again as estimated
by Rockbox.
Voltage The battery voltage in mV at the moment the measurement was taken.
C This stands for Charger. An “A” in that column shows if the power adapter was
attached to the unit at the time of the measurement.
U USB powered. Only for targets that support this. A “U” will indicate if the unit was
using the USB port for power at the time of the measurement.

Chapter 12. Plugins
Usage
The log file can be used to tell you how long the battery lasted (with some limitations, see
below), but it is most useful for graphing discharge curves in order to improve Rockbox’s
estimation of battery level and time remaining. The battery log (battery_bench.txt)
is in CSV format (comma separated variables) and thus can be easily imported into a
spreadsheet or similar program.
Limitations
As Battery Benchmark needs to write the data held in memory to disk in order to
save them, it is possible that should Rockbox shut down due to low battery then there
will not be enough power remaining to write the data to disk. Therefore all measurements
since the previous save will be lost.

2. For each of the above directories, the plugin searches for a subdirectory named
“Lyrics”.
3. Finally, the plugin will search as above, but within a directory called “/Lyrics”.
The name of this directory can be customized, see below.
If the audio file currently playing is /Music/Artist/Album/Title.mp3, then the following files will be searched for, in this order. .ext is one of the supported extensions
from the list above, and will be searched for in the same order as in that list.

In Resistance to Colour mode, use the menus to select the unit that you would like to
use (choose from Ohms, Kiloohms, Megaohms), and use the on-screen keyboard to input
the value of the resistor that you would like to know the colour code of. The colour codes
are presented graphically and textually.
LED resistance
LED resistance calculator is used to determine the resistor necessary to light an LED
safely at a given voltage. First, select the voltage that the LED will use (the first
option is the most common and a safe bet), and the current that it will draw (likewise
with the first option). Then, use the onscreen keyboard to type in the supply voltage
and, if selected, the custom forward current. This function produces safe estimates, but

12.4.17. Rockpaint
Figure 12.51.: Rockpaint
Rockpaint is a bitmap (.bmp) editor for Rockbox. It can open any .bmp file whose dimensions are the same size as your device’s screen or smaller; it can also create empty
bitmaps for you to work with.
Opening A File
To open a file, you may use either the context menu option “Open With” in the File
Browser, or you may enter Rockpaint first using the Plugins menu and open a file from
there. To perform the latter, simply press Rockpaint’s Menu button or move the cursor
beyond the bottom of the screen; then move the cursor onto “Menu” and select it. Finally, select “Load” and navigate to the image you wish to open.
Tools
Rockpaint offers several tools to aid you in editing; you can view them by either pressing
Rockpaint’s “Menu” key or by attempting to move the cursor beyond the bottom of the
screen. From top to bottom and left to right, and by section, they are as follows:
Colour Picker The top left tool shows your colours that are at the ready. To swap them,
“click” on the background colour. To edit the foreground colour, click on it.
Preset Palette Several preset colours are available. Clicking on one changes the foreground of the Colour Picker to the selected colour.
Pencil Draws as you move the cursor. You can change the brush size with the Menu
option “Brush Size”. Use the Select key to toggle the tool while editing the image.
Selection tool Allows you to select a rectangular region; once you do, you will be shown
a menu of options (including “cancel” if you make a mistake).

13.1. Customising the User Interface
13.1.1. Customising The Main Menu
It is possible to customise the main menu, i.e. to reorder or to hide some of its items
(only the main menu can be customised, submenus can not). To accomplish this,
load a .cfg file (as described in section 13.3 (page 166)) containing the following line:
root menu order:items, where “items” is a comma separated list (no spaces around
the commas!) of the following words: bookmarks, files, database, wps, settings,
recording, playlists, plugins, system_menu, shortcuts. Each of the words, if it
occurs in the list, activates the appropriate item in the main menu. The order of the
items is given by the order of the words in the list. The items whose words do not occur
in the list will be hidden, with one exception: the menu item Settings will be shown
even if its word is not in the list (it is added as the last item then).
The following configuration example will change the main menu so that it will contain
only the items for the file browser, for resuming the playback, and for changing the
settings (the latter will be added automatically).
Example
root menu order:files,wps
To reset the menu items to the default, use root menu order:- (i.e. use a hyphen
instead of “items”).
This configuration entry can only be created and edited with a text editor. It is not
possible to change this setting via the settings menu.
13.1.2. Getting Extras
Rockbox supports custom fonts. A collection of fonts is available for download in the
font package at http://www.rockbox.org/daily.shtml.
13.1.3. Loading Fonts
Rockbox can load fonts dynamically. Simply copy the .fnt file to the player and “play”
it in the File Browser. If you want a font to be loaded automatically every time you
start up, it must be located in the /.rockbox/fonts directory and the filename must
be at most 24 characters long. You can browse the fonts in /.rockbox/fonts under
Settings → Theme Settings → Font in the Main Menu.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
Chapter 13. Advanced Topics
158
Note: Advanced Users Only: Any BDF font should be usable with Rockbox. To convert
from .bdf to .fnt, use the convbdf tool. This tool can be found in the tools directory
of the Rockbox source code. See ZCreateFonts#ConvBdf for more details. Or just run
convbdf without any parameters to see the possible options.
b
13.1.4. Loading Languages
Rockbox can load language files at runtime. Simply copy the .lng file (do not use the
.lang file) to the player and “play” it in the Rockbox directory browser or select Settings → General Settings → Language from the Main Menu.
Note: If you want a language to be loaded automatically every time you start up, it
must be located in the /.rockbox/langs directory and the filename must be a maximum
of 24 characters long.
b
If your language is not yet supported and you want to write your own language file
find the instructions on the Rockbox website: ZLangFiles
13.1.5. Changing Filetype Colours
Rockbox has the capability to modify the File Browser to show files of different types
in different colours, depending on the file extension.
Set-up
There are two steps to changing the filetype colours – creating a file with the extension
.colours and then activating it using a config file. The .colours files must be stored
in the /.rockbox/themes/ directory. The .colours file is just a text file, and can be
edited with your text editor of choice.
Creating the .colours file
The .colours file consists of the file extension (or folder) followed by a colon and then
the colour desired as an RGB value in hexadecimal, as in the following example:
folder:808080
mp3:00FF00
ogg:00FF00
txt:FF0000
???:FFFFFF
The permissible extensions are as follows:
folder, m3u, m3u8, cfg, wps, lng, rock, bmark, cue, colours, mpa, mi4, mp1,
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
Chapter 13. Advanced Topics
159
mp2, mp3, ogg, oga, wma, wmv, asf, wav, flac, ac3, a52, mpc, wv, m4a, m4b,
mp4, mod, shn, aif, aiff, spx, sid, adx, nsf, nsfe, spc, ape, mac, sap, mpg,
mpeg, bmp, fnt, kbd
All file extensions that are not either specifically listed in the .colours files or are
not in the list above will be set to the colour given by ???. Extensions that are in the
above list but not in the .colours file will be set to the foreground colour as normal.
Activating
To activate the filetype colours, the .colours file needs to be invoked from a .cfg configuration file. The easiest way to do this is to create a new text file containing the
following single line:
filetype colours:
/.rockbox/themes/filename.colours
where filename is replaced by the filename you used when creating the .colours file.
Save this file as e.g. colours.cfg in the /.rockbox/themes directory and then activate
the config file from the menu as normal (Settings → Theme Settings→ Browse
Theme Files).
Editing
The built-in Text Editor (see section 12.4.20 (page 155)) automatically understands
the .colours file format, but an external text editor can also be used. To edit the
.colours file using Rockbox, “play” it in the File Browser. The file will open in the
Text Editor. Upon selecting a line, the following choices will appear:
Extension
Colour
If Extension is selected, the virtual keyboard (see section 4.1.3 (page 26)) appears,
allowing the file extension to be modified. If Colour is selected, the colour selector screen
appears. Choose the desired colour, then save the .colours file using the standard Text
Editor controls.
13.1.6. Loading Backdrops
Rockbox supports showing an image as a backdrop in the File Browser and the menus.
The backdrop image must be a .bmp file of the exact same dimensions as the display
in your player (128×96×16 with the last number giving the colour depth in bits). To
use an image as a backdrop browse to it in the File Browser and open the Context
Menu (see section 4.1.2 (page 24)) on it and select the option Set As Backdrop. If
you want rockbox to remember your backdrop the next time you start your player the
backdrop must be placed in the /.rockbox/backdrops directory.

Chapter 13. Advanced Topics
13.1.7. UI Viewport
By default, the UI is drawn on the whole screen. This can be changed so that the UI is
confined to a specific area of the screen, by use of a UI viewport. This is done by adding
the following line to the .cfg file for a theme:
ui viewport:
X,Y,[width],[height],[font],[fgcolour],[bgcolour]
Only the first two parameters have to be specified, the others can be omitted using
‘-’ as a placeholder. The syntax is very similar to WPS viewports (see section 13.2.2
(page 161)). Briefly:
• ‘fgcolour’ and ‘bgcolour’ are 6-digit RGB888 colours, e.g. FF00FF.
• ‘font’ is a number: 0 is the built-in system font, 1 is the user-selected font.
Example
ui viewport: 15,20,100,150,-,-,-
This displays the menu starting at 15px from the left of the screen and 20px from the top
of the screen. It is 100px wide and 150px high. The font and the foreground/background
colours are defined in the theme .cfg file or in the Theme Settings menu.
13.2. Configuring the Theme
13.2.1. Themeing – General Info
There are various different aspects of the Rockbox interface that can be themed – the
WPS or While Playing Screen, the FMS or FM Screen (if the player has a tuner),
and the SBS or Base Skin. The WPS is the name used to describe the information
displayed on the player’s screen whilst an audio track is being played, the FMS is the
screen shown while listening to the radio, and the SBS lets you specify a base skin that is
shown in the menus and browsers, as well as the WPS and FMS. The SBS also allows you
to control certain aspects of the appearance of the menus/browsers. There are a number
of themes included in Rockbox, and you can load one of these at any time by selecting
it in Settings → Theme Settings → Browse Theme Files. It is also possible to
set individual items of a theme from within the Settings → Theme Settings menu.
13.2.2. Themes – Create Your Own
The theme files are simple text files, and can be created (or edited) in your favourite
text editor. To make sure non-English characters display correctly in your theme you
must save the theme files with UTF-8 character encoding. This can be done in most
editors, for example Notepad in Windows 2000 or XP (but not in 9x/ME) can do this.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
161
Chapter 13. Advanced Topics
Files Locations: Each different “themeable” aspect requires its own file – WPS files
have the extension .wps, FM screen files have the extension .fms, and SBS files
have the extension .sbs. The main theme file has the extension .cfg. All files
should have the same name.
The theme .cfg file should be placed in the /.rockbox/themes directory, while the
.wps, .fms and .sbs files should be placed in the /.rockbox/wps directory. Any
images used by the theme should be placed in a subdirectory of /.rockbox/wps
with the same name as the theme, e.g. if the theme files are named mytheme.wps,
mytheme.sbs etc., then the images should be placed in /.rockbox/wps/mytheme.
All full list of the available tags are given in appendix section D (page 181); some of
the more powerful concepts in theme design are discussed below.
• All characters not preceded by % are displayed as typed.
• Lines beginning with # are comments and will be ignored.
Note: Keep in mind that your player’s resolution is 128×96×16 (with the last number
giving the colour depth in bits) when designing your own WPS, or if you use a WPS
designed for another target.
Viewports
By default, a viewport filling the whole screen contains all the elements defined in each
theme file. The elements in this viewport are displayed with the same background/
foreground colours and the text is rendered in the same font as in the main menu. To
change this behaviour a custom viewport can be defined. A viewport is a rectangular
window on the screen with its own foreground/background colours. This window also
has variable dimensions. To define a viewport a line starting %V(... has to be present
in the theme file. The full syntax will be explained later in this section. All elements
placed before the line defining a viewport are displayed in the default viewport. Elements
defined after a viewport declaration are drawn within that viewport. Loading images
(see Appendix section D.21 (page 190)) should be done within the default viewport.
A viewport ends either with the end of the file, or with the next viewport declaration
line. Viewports sharing the same coordinates and dimensions cannot be displayed at the
same time. Viewports cannot be layered transparently over one another. Subsequent
viewports will be drawn over any other viewports already drawn onto that area of the
screen.
Viewport Declaration Syntax
%V(x,y,[width],[height],[font]) %Vf([fgcolour]) %Vb([bgcolour]) %Vg(start,
end [,text])
• %Vf and %Vb set the foreground and background colours respectively.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
b
162
Chapter 13. Advanced Topics
• ‘fgcolour’ and ‘bgcolour’ are 6-digit RGB888 colours, e.g. FF00FF.
• %Vg defines a gradient fill that can then be used with the %Vs tag. ‘start’ and
‘end’ set the initial and final colours, and the optional ‘text’ sets the text colour.
Colours are 6-digit RGB888, e.g. FF00FF.
• ‘font’ is a number: 0 is the built-in system font, 1 is the current menu font, and
2-9 are additional skin loaded fonts (see section 13.2.4 (page 164)).
• Only the coordinates have to be specified. Leaving the other definitions blank will
set them to their default values.
Note: The correct number of commas with hyphens in blank fields are still needed.
Example
%V(12,20,-,-,1) %Vf(000000) %Vb(FFFFFF) %Vg(FFC0CB, FF0000, FFFF00)
%sThis viewport is displayed permanently. It starts 12px from the left and
%s20px from the top of the screen, and fills the rest of the screen from
%sthat point. The lines will scroll if this text does not fit in the viewport.
%sThe user font is used, and the foreground and background are set to black
%sand white respectively. The line gradient is set to pink to red with yellow
%text.

Conditional Viewports
Any viewport can be displayed either permanently or conditionally. Defining a viewport
as %V(... will display it permanently.
• %Vl(’identifier’,...) This tag preloads a viewport for later display. ‘identifier’
is a single lowercase letter (a-z) and the ‘. . . ’ parameters use the same logic as the
%V tag explained above.
• %Vd(’identifier’) Display the ‘identifier’ viewport.
Viewports can share identifiers so that you can display multiple viewports with one
%Vd line.
Example
%?C<%Vd(a)|%Vd(b)>
%Vl(a,10,10,50,50,-)
%Cl(0,0,50,50,c,c)
%Cd
%Vl(a,0,70,70,14,1)
%s%acThere you have it: Album art.
%Vl(b,20,14,50,14,1) %Vf(ff0000) %Vb(ffffff)
%t(1)%acWarning:;%t(.1)
%Vl(b,20,30,50,50,1) %Vf(000000) %Vb(ffffff)
%sNo album art found
%scheck your filenames.
This example checks for album art. Album art will be displayed in viewport ‘a’, if it is
found. Otherwise a red flashing warning will be displayed in viewport ‘b’.
Note: The tag to display conditional viewports must come before the tag to preload the
viewport in the .wps file.
13.2.3. Info Viewport (SBS only)
As mentioned above, it is possible to set a UI viewport via the theme .cfg file. It is also
possible to set the UI viewport through the SBS file, and to conditionally select different
UI viewports.
• %Vi(’label’,...) This viewport is used as Custom UI Viewport in the case that
the theme doesn’t have a ui viewport set in the theme .cfg file. Having this is
strongly recommended since it makes you able to use the SBS with other themes.
If label is set this viewport can be selectivly used as the Info Viewport using the
%VI tag. The ‘. . . ’ parameters use the same logic as the %V tag explained above.
• %VI(’label’) Set the Info Viewport to use the viewport called label, as declared
with the previous tag.

13.2.4. Additional Fonts
Additional fonts can be loaded within each screen file to be used in that screen. In this
way not only can you have different fonts between e.g. the menu and the WPS, but you
can use multiple fonts in each of the individual screens.
%Fl(’id’,filename,glyphs)
• ‘id’ is the number you want to use in viewport declarations, 0 and 1 are reserved
and so can’t be used.
• ‘filename’ is the font filename to load. Fonts should be stored in /.rockbox/fonts/
• ‘glyphs’ is an optional specification of how many unique glyphs to store in memory.
Default is from the system setting Glyphs To Load.
An example would be: %Fl(2,12-Nimbus.fnt,100)
Conditional Tags
If/else: Syntax: %?xx<true|false>
If the tag specified by “xx” has a value, the text between the “<” and the “|” is
displayed (the true part), else the text between the “|” and the “>” is displayed
(the false part). The else part is optional, so the “|” does not have to be specified
if no else part is desired. The conditionals nest, so the text in the if and else part
can contain all % commands, including conditionals.
Enumerations: Syntax: %?xx<alt1|alt2|alt3|...|else>
For tags with multiple values, like Play status, the conditional can hold a list of
alternatives, one for each value the tag can have. Example enumeration:
Example
%?mp<Stop|Play|Pause|Ffwd|Rew>
The last else part is optional, and will be displayed if the tag has no value. The
WPS parser will always display the last part if the tag has no value, or if the list
of alternatives is too short.
Next Song Info
You can display information about the next song – the song that is about to play after
the one currently playing (unless you change the plan).
If you use the upper-case versions of the three tags: F, I and D, they will instead refer
to the next song instead of the current one. Example: %Ig is the genre name used in
the next song and %Ff is the mp3 frequency.
Note: The next song information will not be available at all times, but will most likely
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
b
165
Chapter 13. Advanced Topics
be available at the end of a song. We suggest you use the conditional display tag a lot
when displaying information about the next song!
Alternating Sublines
It is possible to group items on each line into 2 or more groups or “sublines”. Each subline
will be displayed in succession on the line for a specified time, alternating continuously
through each defined subline.
Items on a line are broken into sublines with the semicolon ‘;’ character. The display
time for each subline defaults to 2 seconds unless modified by using the ‘%t’ tag to
specify an alternate time (in seconds and optional tenths of a second) for the subline to
be displayed.
Subline related special characters and tags:
; Split items on a line into separate sublines
%t Set the subline display time. The ‘%t’ is followed by either integer seconds (%t5),
or seconds and tenths of a second within () e.g. (%t(3.5)).
Each alternating subline can still be optionally scrolled while it is being displayed, and
scrollable formats can be displayed on the same line with non-scrollable formats (such
as track elapsed time) as long as they are separated into different sublines. Example
subline definition:
Example
%s%t(4)%ia;%s%it;%t(3)%pc %pr : Display id3 artist for 4 seconds,
Display id3 title for 2 seconds,
Display current and remaining track time
for 3 seconds,
repeat...
Conditionals can be used with sublines to display a different set and/or number of
sublines on the line depending on the evaluation of the conditional. Example subline
with conditionals:
Example
%?it<%t(8)%s%it|%s%fn>;%?ia<%t(3)%s%ia|%t(0)>
The format above will do two different things depending if ID3 tags are present. If
the ID3 artist and title are present:
• Display id3 title for 8 seconds,
• Display id3 artist for 3 seconds,
• repeat. . .
If the ID3 artist and title are not present:
• Display the filename continuously.
Note that by using a subline display time of 0 in one branch of a conditional, a subline
can be skipped (not displayed) when that condition is met.

Using Images
You can have as many as 52 images in your WPS. There are various ways of displaying
images:
1. Load and always show the image, using the %x tag
2. Preload the image with %xl and show it with %xd. This way you can have your
images displayed conditionally.
3. Load an image and show as backdrop using the %X tag. The image must be of the
same exact dimensions as your display.
Example on background image use:
Example
%X(background.bmp)
The image with filename background.bmp is loaded and used in the WPS.
Example on bitmap preloading and use:
Example
%x(a,static_icon.bmp,50,50)
%xl(b,rep_off.bmp,16,64)
%xl(c,rep_all.bmp,16,64)
%xl(d,rep_one.bmp,16,64)
%xl(e,rep_shuffle.bmp,16,64)
%?mm<%xd(b)|%xd(c)|%xd(d)|%xd(e)>
Four images at the same x and y position are preloaded in the example. Which image
to display is determined by the %mm tag (the repeat mode).
Example File
Example
%s%?in<%in - >%?it<%it|%fn> %?ia<[%ia%?id<, %id>]>
%pb%pc/%pt
That is, “tracknum – title [artist, album]”, where most fields are only displayed if available. Could also be rendered as “filename” or “tracknum – title [artist]”.
13.3. Managing Rockbox Settings
13.3.1. Introduction to .cfg Files
Rockbox allows users to store and load multiple settings through the use of configuration
files. A configuration file is simply a text file with the extension .cfg.
A configuration file may reside anywhere on the disk. Multiple configuration files are
permitted. So, for example, you could have a car.cfg file for the settings that you use

while playing your jukebox in your car, and a headphones.cfg file to store the settings
that you use while listening to your player through headphones.
See section 13.3.2 (page 167) below for an explanation of the format for configuration
files. See section 13.3.3 (page 168) for an explanation of how to create, edit and load
configuration files.
13.3.2. Specifications for .cfg Files
The Rockbox configuration file is a plain text file, so once you use the Save .cfg file
option to create the file, you can edit the file on your computer using any text editor
program. See Appendix section E (page 197) for available settings. Configuration files
use the following formatting rules:
1. Each setting must be on a separate line.
2. Each line has the format “setting: value”.
3. Values must be within the ranges specified in this manual for each setting.
4. Lines starting with # are ignored. This lets you write comments into your configuration files.
Example of a configuration file:
Example
volume: 70
bass: 11
treble: 12
balance: 0
time format: 12hour
volume display: numeric
show files: supported
wps: /.rockbox/car.wps
lang: /.rockbox/afrikaans.lng
Note: As you can see from the example, configuration files do not need to contain all
of the Rockbox options. You can create configuration files that change only certain settings. So, for example, suppose you typically use the player at one volume in the car,
and another when using headphones. Further, suppose you like to use an inverse LCD
when you are in the car, and a regular LCD setting when you are using headphones. You
could create configuration files that control only the volume and LCD settings. Create a
few different files with different settings, give each file a different name (such as car.cfg,
headphones.cfg, etc.), and you can then use the Browse .cfg files option to quickly
change settings.
A special case configuration file can be used to force a particular setting or settings
every time Rockbox starts up (e.g. to set the volume to a safe level). Format a new
configuration file as above with the required setting(s) and save it into the /.rockbox
directory with the filename fixed.cfg.

13.3.3. The Manage Settings menu
The Manage Settings menu can be found in the Main Menu. The Manage Settings menu allows you to save and load .cfg files.
Browse .cfg Files Opens the File Browser in the /.rockbox directory and displays
all .cfg (configuration) files. Selecting a .cfg file will cause Rockbox to load the
settings contained in that file. Pressing Left or Long Left will exit back to the
Manage Settings menu. See the Write .cfg files option on the Manage
Settings menu for details of how to save and edit a configuration file.
Reset Settings This wipes the saved settings in the player and resets all settings to
their default values.
Note: You can also reset all settings to their default values by turning off the
player, turning it back on, and holding the Rec button immediately after the
player turns on.
Save .cfg File This option writes a .cfg file to your player’s disk. The configuration
file has the .cfg extension and is used to store all of the user settings that are
described throughout this manual.
Hint: Use the Save .cfg File feature (Main Menu → Manage Settings) to
save the current settings, then use a text editor to customize the settings file. See
Appendix section E (page 197) for the full reference of available options.
Save Sound Settings This option writes a .cfg file to your player’s disk. The configuration file has the .cfg extension and is used to store all of the sound related
settings.
Save Theme Settings This option writes a .cfg file to your player’s disk. The configuration file has the .cfg extension and is used to store all of the theme related
settings.
13.4. Firmware Loading
13.4.1. Using ROLO (Rockbox Loader)
Rockbox is able to load and start another firmware file without rebooting. You just
“play” a file with the extension
.mi4.
This can be used to test new firmware
versions without deleting your current version.
13.5. Optimising battery runtime
Rockbox offers a lot of settings that have high impact on the battery runtime of your
player. The largest power savings can be achieved through disabling unneeded hardware

Chapter 13. Advanced Topics
169
components – for some of those there are settings available. Another area of savings is
avoiding or reducing CPU boosting through disabling computing intense features (e.g.
sound processing) or using effective audio codecs.
The following provides a short
overview of the most relevant settings and rules of thumb.
13.5.1. Display backlight
The active backlight consumes a lot of power. Therefore choose a setting that disables
the backlight after timeout (for setting Backlight see section 8.4 (page 64)). Avoid to
have the backlight enabled all the time.
13.5.2. Anti-Skip Buffer
Having a large anti-skip buffer tends to use more power, and may reduce your battery
life. It is recommended to always use the lowest possible setting that allows correct and
continuous playback (see section 7.5 (page 56)).
13.5.3. Replaygain
Replaygain is a post processing that equalises the playback volume of audio files to
the same perceived loudness. This post processing applies a factor to each single PCM
sample and is therefore consuming additional CPU time. If you want to achieve some
(minor) savings in runtime, switch this feature off (see section 7.9 (page 58)).
13.5.4. Peak Meter
The peak meter is a feature of the While Playing Screen and will be updated with a
high framerate. Depending on your player this might result in a high CPU load. To
save battery runtime you should switch this feature off (see section 4.3.2 (page 31)).
13.5.5. Audio format and bitrate
In general the fastest decoding audio format will be the best in terms of battery runtime
on your player. An overview of different codec’s performance on different players can be
found at ZCodecPerformanceComparison.
Your target uses a hard disk which consumes a large amount of power while spinning
– up to several hundred mA. The less often the hard disk needs to spin up for buffering
and the shorter the buffering duration is, the lower is the power consumption. Therefore
the bitrate of the audio files does have an impact on the battery runtime as well. Lower
bitrate audio files will result in longer battery runtime.
Please do not re-encode any existing audio files from one lossy format to another based
upon the above mentioned. This will reduce the audio quality. If you have the choice,
select the best suiting codec when encoding the original source material.

13.5.6. Sound settings
In general all kinds of sound processing will need more CPU time and therefore consume
more power. The less sound processing you use, the better it is for the battery runtime
(for options see section 6 (page 47)).

Appendix C. Album Art
C. Album Art
Rockbox allows you to put the album art, or another image related to the music on your
player to display it in the PictureFlow plugin or in the theme. For this feature to work,
there are a few requirements.
C.1. Limitations
Rockbox supports embedded album art only for some specific formats, see section B.2.1
(page 177) for full details. It additionally supports loading images located on the hard
disk. PictureFlow is currently unable to use embedded album art. The image files must
be in either BMP or JPEG format, while embedded album art is currently limited to
JPEG. Embedded JPEG images must not be unsynchronized. Rockbox does not support
RLE-compressed BMP files, nor does it support progressive and multi-scan JPEG files.
JPEG files must consist of a single scan with interleaved components, as progessive and
multi-scan images require much more memory to decode.
C.2. Where to put album art
The pictures can be named a number of different ways, and placed to a number of
different locations. You can have pictures specific to the file or the album or use a
generic picture. You can place the picture in the same directory as the file, in the parent
directory or in a fixed directory named /.rockbox/albumart/. The order Rockbox uses
when looking for a picture is as follows (a list in braces means that those file extensions
are tried in that order):
1. embedded (JPEG images in ID3v2 or MP4 tags only)
2. ./filename.{jpeg,jpg,bmp}
3. ./albumtitle.{jpeg,jpg,bmp}
4. ./cover.{jpeg,jpg,bmp}
5. ./folder.jpg
6. /.rockbox/albumart/albumartist-albumtitle.{jpeg,jpg,bmp}
7. ../albumtitle.{jpeg,jpg,bmp}
8. ../cover.{jpeg,jpg,bmp}

Appendix D. Theme Tags
D. Theme Tags
Themeing is discussed in detail in section section 13.2 (page 160), what follows is a list
of the available tags.
Note: The “bar-type tags” (such as %pb, %pv, %bl etc.) can be further themed – see
section D.27 (page 194).
D.1. Status Bar
Tag
Description
%we
%wd
%wi
Display Status Bar
Hide Status Bar
Display the inbuilt Status Bar in the current viewport
These tags override the player setting for the display of the status bar. They must be
noted on their own line (which will not be shown in the WPS).
D.2. Hardware Capabilities
Tag
Description
%cc
Check for presence of a real time clock, returns “c” when used
unconditionally
Does this target have a radio?
Indicates that the target has a touchscreen
%tp
%Tp
With the above tags it is possible to find out about the presence of certain hardware
and make the theme adapt to it. This can be very useful for designing a theme that
works on multiple targets with differing hardware capabilities, e.g. targets that do and
do not have a clock. When used conditionally, the “true” branch is completely ignored
if it does not apply.
Example: %?cc<%cH:%cM|No clock detected>

Playlist position
Remaining time in song
“s” if shuffle mode is enabled
Total track time
Current volume (in dB). Can also be used in a conditional:
%?pv<Mute|...|0 dB|Above 0 dB>
Mute is 0% volume, . . . is the values between Mute and max,
0 dB is max volume, and Above 0 dB is amplified volume
This can also be used like %pb to provide a continuous scale:
%pv(x,y,[width],[height],image.bmp)
Track is starting. An optional number gives how many seconds
the tag remains true for after the start of the track. The default is 10 seconds if no number is specified. %?pS(7)<in the
first 7 seconds of track|in the rest of the track>
Track is ending. An optional number gives how many seconds
before the end of the track the tag becomes true. The default
is 10 seconds if no number is specified. %?pE(7)<in the last
7 seconds of track|in the rest of the track>

• ‘start’ is the offset relative to the currently playing track for the playlist to display
from (0 the current track, 1 is the next track, etc.).
• ‘code to render’ is a line of skin code which will be displayed for each line in the
viewer. All text tags are supported (including conditionals and sublines)
The entire viewport will be used, so don’t expect other tags in the same viewport to
work well. Supported tags are %pp, all tags starting with %i, most tags starting with
%f, %pt and %s.
Example: %Vp(1,%pp - %it,%pp - %fn) – Display the playlist position, then either
the track title (from the tags) or the filename. The viewer will display as many tracks
as will fit in the viewport.

screens don’t show a title when they shouldn’t
Title icon. This uses the same order as custom icons (see
ZCustomIcons in the wiki) except that here 0 is “no icon”
%Li
This tag can be used to give custom formatting to list titles. Define a viewport with
the font and formatting desired, and then use %?Lt<%Lt> to display the title within the
viewport. If %Lt is present anywhere in the .sbs, then the %Vi viewport will not show
the title.

D.19. Changing Volume
Tag
Description
%mv(t)
“v” if the volume is being changed
The tag produces the letter “v” while the volume is being changed and some amount of
time after that, i.e. after the volume button has been released. The optional parameter
t specifies that amount of time, in seconds. If it is not specified, 1 second is assumed.
The tag can be used as the switch in a conditional tag to display different things
depending on whether the volume is being changed. It can produce neat effects when
used with conditional viewports.
Example: %?mv(2.5)<Volume changing|%pv>
The example above will display the text “Volume changing” if the volume is being
changed and 2.5 seconds after the volume button has been released. After that, it will
display the volume value.

Note:
• The images must be in BMP format
• The image tag must be on its own line
• The ID is case sensitive
• The size of the LCD screen for each player varies. See table below for appropriate
sizes of each device. The x and y coordinates must respect each of the player’s
limits.
D.21.1. How to display the album art
Once the album art files are present on your player, they can be displayed as follows.
Tag
Description
%Cl(x,y,[maxwidth],
[maxheight],
hor_align,
vert_align)
Define the settings for album art
x: x coordinate
y: y coordinate
maxwidth: Maximum height
maxheight: Maximum width
hor_align: Horizontal alignment, enter as ‘l’, ‘c’ or ‘r’ for
left, centre or right. Centre is default
vert_align: Vertical alignment, enter as ‘t’, ‘c’ or ‘b’ for top,
centre or bottom. Centre is default
Display the album art as configured.
Use in a conditional to determine if an image is available.
%Cd
%C
The picture will be rescaled, preserving aspect ratio to fit the given maxwidth and
maxheight. If the aspect ratio doesn’t match the configured values, the picture will be
placed according to the alignment flags.
Examples:
1. Load albumart at position 20,40 and display it without resizing:
%Cl(20,40„)
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
192
Appendix D. Theme Tags
2. Load albumart at position 0,20 and resize it to be at most 100×100 pixels. If the
image isn’t square, align it to the bottom-right corner:
%Cl(0,20,100,100,r,b)
For general information where to put album art see section C (page 179).
D.22. Alignment and language direction
Tag
Description
%al
%aL
%ac
%ar
%aR
%ax
Align the text left
Align the text left, or to the right if RTL language is in use
Centre the text
Align the text right
Align the text right, or to the left if RTL language is in use
The next tag should follow the set language direction. When
prepended to a viewport declaration, the viewport will be
horizontally mirrored if the user language is set to a RTL
language. Currently the %Cl, %V and %Vl tags support this.
Use as a conditional to define options for left to right, or right
to left languages. %?Sr<RTL|LTR>
%Sr
All alignment tags may be present in one line, but they need to be in the order left –
centre – right. If the aligned texts overlap, they are merged.
Example: %ax%V(...)

%if(tag,
operator,
operand, [option
count])
%and(tag1, tag2,
..., tagN)
If / Else: Evaluate for true or false case
Enumerations: Evaluate for first / second / third / . . . / last
condition
Allows very simple comparisons with other tags.
tag: the tag to check against.
operator: the comparison to perform - possible options are
=, !=, >, >=, <, <=
operand: either a second tag, a number, or text.
[option count]: optional parameter used to select which parameter of a tag to use when the tag has multiple options, e.g.
%?pv<a|b|c|d>
Logical “and” operator. Will be evaluate to true if all the tag
parameters are true.
%or(tag1, tag2,
..., tagN)
Logical “or” operator. Will be evaluate to true if any of the
tag parameters are true.
Examples of the %if tag:
%?if(%pv, >=, 0)<Clipping possible|Volume OK> will display “Clipping possible”
if the volume is higher than or equal to 0 dB, “Volume OK” if it is lower.
%?if(%ia, =, %Ia)<same artist> – this artist and the next artist are the same.
Note: When performing a comparison against a string tag such as %ia, only = and !=
work, and the comparison is not case sensitive.
D.24. Subline Tags
Tag
Description
%t(time)
;
Set the subline display cycle time (%t(5) or %t(3.4) formats)
Split items on a line into separate sublines
Allows grouping of several items (sublines) onto one line, with the display cycling
round the defined sublines. See section 13.2.4 (page 165) for details.

D.27. Bar Tags
Some tags can be used to display a bar which draws according to the value of the tag.
To use these tags like a bar you need to use the following parameters (%XX should be
replaced with the actual tag).

(version rUnversioned directory-141114)
Samsung YH-820
b
195
Appendix D. Theme Tags
Tag
Description
%XX(x, y,
width, height,
[options])
Draw the specified tag as a bar
x: x co-ordinate at which to start drawing the bar.
y: y co-ordinate at which to start drawing the bar (- to make
the bar appear on the line of the tag, as if it was a text tag) .
width: width of the bar (- for the full viewport width).
height: height of the bar (- to set to the font height for
horizontal bars and to the viewport height for vertical bars).
options: any of the options set out below.
D.27.1. Options
image – the next option is either the filename or image label to use for the fill image.
horizontal – force the bar to be drawn horizontally.
vertical – force the bar to be drawn vertically.
invert – invert the draw direction (i.e. right to left, or top to bottom).
slider – draw a preloaded image over the top of the bar so that the centre of the image
matches the current position. This must be followed by the label of the desired
image.
backdrop – draw a preloaded image under the bar. The full image will be displayed
and must be the same size as the bar. This must be followed by the label of the
desired image.
nofill – don’t draw the bar, only its frame (for use with the “slider” option).
noborder – don’t draw the border for image-less bars, instead maximise the filling over
the specified area. This doesn’t work for bars which specify an image.
nobar – don’t draw the bar or its frame (for use with the “slider” option).
setting – Specify the setting name to draw the bar from (bar must be %St type), the
next param is the settings config name.
Example: %pb(0,0,-,-,-,nofill, slider, slider_image, invert) – draw a horizontal progressbar which doesn’t fill and draws the image “slider_image” which moves
right to left.
Note: If the slider option is used, the bar will be shrunk so that the slider fits inside
the specified width and height. Example: A 100px bar image with a 16px slider image
needs the bar to be 116px wide, and should be offset 8px left of the backdrop image to
align correctly.

G. User feedback
G.1. Bug reports
If you experience inappropriate performance from any supported feature, please file a
bug report on our web page. Do not report missing features as bugs, instead file them
as feature ideas (see below).
For open bug reports refer to http://www.rockbox.org/tracker/index.php?type=2
G.1.1. Rules for submitting new bug reports
1. Check that the bug has not already been reported
2. Always include the following information in your bug report:
• Which exact player you have.
• Which exact Rockbox version you are using (Menu → System → Rockbox
Info → Version)
• A step-by-step description of what you did and what happened
• Whether the problem is repeatable or a one-time occurrence
• All relevant data regarding the problem, such as playlists, MP3 files etc.
(IMPORTANT!)
G.2. Feature ideas
To suggest an idea for a feature or to read those made by others, see http://forums.
rockbox.org/index.php?board=49.0. Please keep in mind that this forum is for the discussion of feature ideas - they are not requests and there is no guarantee they will be
acted upon.
G.2.1. Rules for submitting a new feature idea
1. Check that the feature has not already been suggested. Duplicates are really
boring!
2. Check that the feature has not already been implemented. Download the latest
current/daily build and/or search the mail list archive.
3. Check that the feature is possible to implement (see section G.2.2 (page 205)).

G.2.2. Features we will not implement
This is a list of Feature Requests we get repeatedly that we simply cannot do. View it
as the opposite of a TODO!
• Interfacing with other USB devices (like cameras) or 2 player games over USB.
The USB system demands that there is a master that talks to a slave. The player
can only serve as a slave, as most other USB devices such as cameras can. Thus,
without a master no communication between the slaves can take place. If that is
not enough, we have no way of actually controlling the communication performed
over USB since the USB circuit in the player is strictly made for disk-access and
does not allow us to play with it the way we’d need for any good communication
to work.
• Support other file systems than FAT32 (like NTFS or ext2 etc.).
No. support for more file systems will just take away valuable ram for unnecessary
features. You can partition your player fine, just make sure the first one is FAT32
and then make the other ones whatever file system you want. Just do not expect
Rockbox to understand them.
• Add scandisk-like features.
It would be a very slow operation that would drain the batteries and take a lot of
useful ram for something that is much better and faster done when connected to
a host computer.
• Alphabetical list skipping.
Skipping around the lists by jumping letters (i.e skip all C’s and go straight to the
first D). This isn’t feasible with the current list implementation, if you really want
this you can get similar effects using the database (see section 4.2 (page 27)).
• Add support for non standard tag formats.
APE tags in MP3 files has been rejected a few times already. Its not something
we want.
• Implementing the ability to playback DRM files.
Firstly, this would be extremely difficult to implement legally - Rockbox is not
legal entity as such, and therefore is unable to enter into license agreements with
providers of DRM technology. Secondly, Rockbox is open source, which would
mean that any DRM technology we incorporated into our codebase would suddenly become visible to the whole world, completely defeating its purpose. Remember, DRM achieves part of its security through obscurity, and publishing the
keys necessary to decrypt DRM’d media would essentially render it useless.

I.1. GNU Free Documentation License
Version 1.2, November 2002
Copyright c 2000,2001,2002 Free Software Foundation, Inc.
51 Franklin St, Fifth Floor, Boston, MA 02110-1301 USA
Everyone is permitted to copy and distribute verbatim copies of this license document,
but changing it is not allowed.
Preamble
The purpose of this License is to make a manual, textbook, or other functional and
useful document “free” in the sense of freedom: to assure everyone the effective freedom
to copy and redistribute it, with or without modifying it, either commercially or noncommercially. Secondarily, this License preserves for the author and publisher a way to
get credit for their work, while not being considered responsible for modifications made
by others.
This License is a kind of “copyleft”, which means that derivative works of the document
must themselves be free in the same sense. It complements the GNU General Public
License, which is a copyleft license designed for free software.
We have designed this License in order to use it for manuals for free software, because free software needs free documentation: a free program should come with manuals
providing the same freedoms that the software does. But this License is not limited to
software manuals; it can be used for any textual work, regardless of subject matter or
whether it is published as a printed book. We recommend this License principally for
works whose purpose is instruction or reference.
1. APPLICABILITY AND DEFINITIONS
This License applies to any manual or other work, in any medium, that contains a notice
placed by the copyright holder saying it can be distributed under the terms of this
License. Such a notice grants a world-wide, royalty-free license, unlimited in duration,
to use that work under the conditions stated herein. The “Document”, below, refers
to any such manual or work. Any member of the public is a licensee, and is addressed
as “you”. You accept the license if you copy, modify or distribute the work in a way
requiring permission under copyright law.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
211
Appendix I. Licenses
A “Modified Version” of the Document means any work containing the Document
or a portion of it, either copied verbatim, or with modifications and/or translated into
another language.
A “Secondary Section” is a named appendix or a front-matter section of the Document that deals exclusively with the relationship of the publishers or authors of the
Document to the Document’s overall subject (or to related matters) and contains nothing
that could fall directly within that overall subject. (Thus, if the Document is in part a
textbook of mathematics, a Secondary Section may not explain any mathematics.) The
relationship could be a matter of historical connection with the subject or with related
matters, or of legal, commercial, philosophical, ethical or political position regarding
them.
The “Invariant Sections” are certain Secondary Sections whose titles are designated,
as being those of Invariant Sections, in the notice that says that the Document is released
under this License. If a section does not fit the above definition of Secondary then it is
not allowed to be designated as Invariant. The Document may contain zero Invariant
Sections. If the Document does not identify any Invariant Sections then there are none.
The “Cover Texts” are certain short passages of text that are listed, as Front-Cover
Texts or Back-Cover Texts, in the notice that says that the Document is released under
this License. A Front-Cover Text may be at most 5 words, and a Back-Cover Text may
be at most 25 words.
A “Transparent” copy of the Document means a machine-readable copy, represented
in a format whose specification is available to the general public, that is suitable for revising the document straightforwardly with generic text editors or (for images composed
of pixels) generic paint programs or (for drawings) some widely available drawing editor, and that is suitable for input to text formatters or for automatic translation to a
variety of formats suitable for input to text formatters. A copy made in an otherwise
Transparent file format whose markup, or absence of markup, has been arranged to
thwart or discourage subsequent modification by readers is not Transparent. An image
format is not Transparent if used for any substantial amount of text. A copy that is not
“Transparent” is called “Opaque”.
Examples of suitable formats for Transparent copies include plain ASCII without
markup, Texinfo input format, LaTeX input format, SGML or XML using a publicly
available DTD, and standard-conforming simple HTML, PostScript or PDF designed
for human modification. Examples of transparent image formats include PNG, XCF
and JPG. Opaque formats include proprietary formats that can be read and edited only
by proprietary word processors, SGML or XML for which the DTD and/or processing
tools are not generally available, and the machine-generated HTML, PostScript or PDF
produced by some word processors for output purposes only.
The “Title Page” means, for a printed book, the title page itself, plus such following
pages as are needed to hold, legibly, the material this License requires to appear in the
title page. For works in formats which do not have any title page as such, “Title Page”
means the text near the most prominent appearance of the work’s title, preceding the
beginning of the body of the text.
A section “Entitled XYZ” means a named subunit of the Document whose title ei-

Appendix I. Licenses
ther is precisely XYZ or contains XYZ in parentheses following text that translates XYZ
in another language. (Here XYZ stands for a specific section name mentioned below,
such as “Acknowledgements”, “Dedications”, “Endorsements”, or “History”.)
To “Preserve the Title” of such a section when you modify the Document means that
it remains a section “Entitled XYZ” according to this definition.
The Document may include Warranty Disclaimers next to the notice which states that
this License applies to the Document. These Warranty Disclaimers are considered to be
included by reference in this License, but only as regards disclaiming warranties: any
other implication that these Warranty Disclaimers may have is void and has no effect
on the meaning of this License.
2. VERBATIM COPYING
You may copy and distribute the Document in any medium, either commercially or
noncommercially, provided that this License, the copyright notices, and the license notice
saying this License applies to the Document are reproduced in all copies, and that you
add no other conditions whatsoever to those of this License. You may not use technical
measures to obstruct or control the reading or further copying of the copies you make
or distribute. However, you may accept compensation in exchange for copies. If you
distribute a large enough number of copies you must also follow the conditions in section
3.
You may also lend copies, under the same conditions stated above, and you may
publicly display copies.
3. COPYING IN QUANTITY
If you publish printed copies (or copies in media that commonly have printed covers) of
the Document, numbering more than 100, and the Document’s license notice requires
Cover Texts, you must enclose the copies in covers that carry, clearly and legibly, all
these Cover Texts: Front-Cover Texts on the front cover, and Back-Cover Texts on the
back cover. Both covers must also clearly and legibly identify you as the publisher of
these copies. The front cover must present the full title with all words of the title equally
prominent and visible. You may add other material on the covers in addition. Copying
with changes limited to the covers, as long as they preserve the title of the Document
and satisfy these conditions, can be treated as verbatim copying in other respects.
If the required texts for either cover are too voluminous to fit legibly, you should put
the first ones listed (as many as fit reasonably) on the actual cover, and continue the
rest onto adjacent pages.
If you publish or distribute Opaque copies of the Document numbering more than 100,
you must either include a machine-readable Transparent copy along with each Opaque
copy, or state in or with each Opaque copy a computer-network location from which
the general network-using public has access to download using public-standard network
protocols a complete Transparent copy of the Document, free of added material. If
you use the latter option, you must take reasonably prudent steps, when you begin

Appendix I. Licenses
distribution of Opaque copies in quantity, to ensure that this Transparent copy will
remain thus accessible at the stated location until at least one year after the last time
you distribute an Opaque copy (directly or through your agents or retailers) of that
edition to the public.
It is requested, but not required, that you contact the authors of the Document well
before redistributing any large number of copies, to give them a chance to provide you
with an updated version of the Document.
4. MODIFICATIONS
You may copy and distribute a Modified Version of the Document under the conditions
of sections 2 and 3 above, provided that you release the Modified Version under precisely
this License, with the Modified Version filling the role of the Document, thus licensing
distribution and modification of the Modified Version to whoever possesses a copy of it.
In addition, you must do these things in the Modified Version:
A. Use in the Title Page (and on the covers, if any) a title distinct from that of the
Document, and from those of previous versions (which should, if there were any,
be listed in the History section of the Document). You may use the same title as
a previous version if the original publisher of that version gives permission.
B. List on the Title Page, as authors, one or more persons or entities responsible for
authorship of the modifications in the Modified Version, together with at least five
of the principal authors of the Document (all of its principal authors, if it has fewer
than five), unless they release you from this requirement.
C. State on the Title page the name of the publisher of the Modified Version, as the
publisher.
D. Preserve all the copyright notices of the Document.
E. Add an appropriate copyright notice for your modifications adjacent to the other
copyright notices.
F. Include, immediately after the copyright notices, a license notice giving the public
permission to use the Modified Version under the terms of this License, in the form
shown in the Addendum below.
G. Preserve in that license notice the full lists of Invariant Sections and required Cover
Texts given in the Document’s license notice.
H. Include an unaltered copy of this License.
I. Preserve the section Entitled “History”, Preserve its Title, and add to it an item
stating at least the title, year, new authors, and publisher of the Modified Version as
given on the Title Page. If there is no section Entitled “History” in the Document,
create one stating the title, year, authors, and publisher of the Document as given
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
214
Appendix I. Licenses
on its Title Page, then add an item describing the Modified Version as stated in
the previous sentence.
J. Preserve the network location, if any, given in the Document for public access to
a Transparent copy of the Document, and likewise the network locations given in
the Document for previous versions it was based on. These may be placed in the
“History” section. You may omit a network location for a work that was published
at least four years before the Document itself, or if the original publisher of the
version it refers to gives permission.
K. For any section Entitled “Acknowledgements” or “Dedications”, Preserve the Title
of the section, and preserve in the section all the substance and tone of each of the
contributor acknowledgements and/or dedications given therein.
L. Preserve all the Invariant Sections of the Document, unaltered in their text and
in their titles. Section numbers or the equivalent are not considered part of the
section titles.
M. Delete any section Entitled “Endorsements”. Such a section may not be included
in the Modified Version.
N. Do not retitle any existing section to be Entitled “Endorsements” or to conflict in
title with any Invariant Section.
O. Preserve any Warranty Disclaimers.
If the Modified Version includes new front-matter sections or appendices that qualify
as Secondary Sections and contain no material copied from the Document, you may at
your option designate some or all of these sections as invariant. To do this, add their
titles to the list of Invariant Sections in the Modified Version’s license notice. These
titles must be distinct from any other section titles.
You may add a section Entitled “Endorsements”, provided it contains nothing but
endorsements of your Modified Version by various parties–for example, statements of
peer review or that the text has been approved by an organization as the authoritative
definition of a standard.
You may add a passage of up to five words as a Front-Cover Text, and a passage of up
to 25 words as a Back-Cover Text, to the end of the list of Cover Texts in the Modified
Version. Only one passage of Front-Cover Text and one of Back-Cover Text may be
added by (or through arrangements made by) any one entity. If the Document already
includes a cover text for the same cover, previously added by you or by arrangement
made by the same entity you are acting on behalf of, you may not add another; but you
may replace the old one, on explicit permission from the previous publisher that added
the old one.
The author(s) and publisher(s) of the Document do not by this License give permission
to use their names for publicity for or to assert or imply endorsement of any Modified
Version.

Appendix I. Licenses
5. COMBINING DOCUMENTS
You may combine the Document with other documents released under this License,
under the terms defined in section 4 above for modified versions, provided that you
include in the combination all of the Invariant Sections of all of the original documents,
unmodified, and list them all as Invariant Sections of your combined work in its license
notice, and that you preserve all their Warranty Disclaimers.
The combined work need only contain one copy of this License, and multiple identical
Invariant Sections may be replaced with a single copy. If there are multiple Invariant
Sections with the same name but different contents, make the title of each such section
unique by adding at the end of it, in parentheses, the name of the original author or
publisher of that section if known, or else a unique number. Make the same adjustment
to the section titles in the list of Invariant Sections in the license notice of the combined
work.
In the combination, you must combine any sections Entitled “History” in the various
original documents, forming one section Entitled “History”; likewise combine any sections Entitled “Acknowledgements”, and any sections Entitled “Dedications”. You must
delete all sections Entitled “Endorsements”.
6. COLLECTIONS OF DOCUMENTS
You may make a collection consisting of the Document and other documents released
under this License, and replace the individual copies of this License in the various documents with a single copy that is included in the collection, provided that you follow the
rules of this License for verbatim copying of each of the documents in all other respects.
You may extract a single document from such a collection, and distribute it individually under this License, provided you insert a copy of this License into the extracted
document, and follow this License in all other respects regarding verbatim copying of
that document.
7. AGGREGATION WITH INDEPENDENT WORKS
A compilation of the Document or its derivatives with other separate and independent
documents or works, in or on a volume of a storage or distribution medium, is called an
“aggregate” if the copyright resulting from the compilation is not used to limit the legal
rights of the compilation’s users beyond what the individual works permit. When the
Document is included in an aggregate, this License does not apply to the other works in
the aggregate which are not themselves derivative works of the Document.
If the Cover Text requirement of section 3 is applicable to these copies of the Document, then if the Document is less than one half of the entire aggregate, the Document’s
Cover Texts may be placed on covers that bracket the Document within the aggregate,
or the electronic equivalent of covers if the Document is in electronic form. Otherwise
they must appear on printed covers that bracket the whole aggregate.

Appendix I. Licenses
8. TRANSLATION
Translation is considered a kind of modification, so you may distribute translations of the
Document under the terms of section 4. Replacing Invariant Sections with translations
requires special permission from their copyright holders, but you may include translations
of some or all Invariant Sections in addition to the original versions of these Invariant
Sections. You may include a translation of this License, and all the license notices in the
Document, and any Warranty Disclaimers, provided that you also include the original
English version of this License and the original versions of those notices and disclaimers.
In case of a disagreement between the translation and the original version of this License
or a notice or disclaimer, the original version will prevail.
If a section in the Document is Entitled “Acknowledgements”, “Dedications”, or “History”, the requirement (section 4) to Preserve its Title (section 1) will typically require
changing the actual title.
9. TERMINATION
You may not copy, modify, sublicense, or distribute the Document except as expressly
provided for under this License. Any other attempt to copy, modify, sublicense or
distribute the Document is void, and will automatically terminate your rights under
this License. However, parties who have received copies, or rights, from you under this
License will not have their licenses terminated so long as such parties remain in full
compliance.
10. FUTURE REVISIONS OF THIS LICENSE
The Free Software Foundation may publish new, revised versions of the GNU Free Documentation License from time to time. Such new versions will be similar in spirit to
the present version, but may differ in detail to address new problems or concerns. See
http://www.gnu.org/copyleft/.
Each version of the License is given a distinguishing version number. If the Document specifies that a particular numbered version of this License “or any later version”
applies to it, you have the option of following the terms and conditions either of that
specified version or of any later version that has been published (not as a draft) by the
Free Software Foundation. If the Document does not specify a version number of this
License, you may choose any version ever published (not as a draft) by the Free Software
Foundation.
ADDENDUM: How to use this License for your documents
To use this License in a document you have written, include a copy of the License in the
document and put the following copyright and license notices just after the title page:

Appendix I. Licenses
Copyright c YEAR YOUR NAME. Permission is granted to copy, distribute
and/or modify this document under the terms of the GNU Free Documentation License, Version 1.2 or any later version published by the Free Software
Foundation; with no Invariant Sections, no Front-Cover Texts, and no BackCover Texts. A copy of the license is included in the section entitled “GNU
Free Documentation License”.
If you have Invariant Sections, Front-Cover Texts and Back-Cover Texts, replace the
“with...Texts.” line with this:
with the Invariant Sections being LIST THEIR TITLES, with the FrontCover Texts being LIST, and with the Back-Cover Texts being LIST.
If you have Invariant Sections without Cover Texts, or some other combination of the
three, merge those two alternatives to suit the situation.
If your document contains nontrivial examples of program code, we recommend releasing these examples in parallel under your choice of free software license, such as the
GNU General Public License, to permit their use in free software.

Version 2, June 1991
Copyright c 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license document,
but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and
change it. By contrast, the GNU General Public License is intended to guarantee your
freedom to share and change free software—to make sure the software is free for all its
users. This General Public License applies to most of the Free Software Foundation’s
software and to any other program whose authors commit to using it. (Some other Free
Software Foundation software is covered by the GNU Library General Public License
instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General
Public Licenses are designed to make sure that you have the freedom to distribute copies
of free software (and charge for this service if you wish), that you receive source code or
can get it if you want it, that you can change the software or use pieces of it in new free
programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you
these rights or to ask you to surrender the rights. These restrictions translate to certain
responsibilities for you if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee,
you must give the recipients all the rights that you have. You must make sure that they,
too, receive or can get the source code. And you must show them these terms so they
know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this
license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author’s protection and ours, we want to make certain that everyone
understands that there is no warranty for this free software. If the software is modified
by someone else and passed on, we want its recipients to know that what they have is not
the original, so that any problems introduced by others will not reflect on the original
authors’ reputations.
Finally, any free program is threatened constantly by software patents. We wish to
avoid the danger that redistributors of a free program will individually obtain patent
licenses, in effect making the program proprietary. To prevent this, we have made it
clear that any patent must be licensed for everyone’s free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.

Appendix I. Licenses
Terms and Conditions For Copying, Distribution and
Modification
0. This License applies to any program or other work which contains a notice placed
by the copyright holder saying it may be distributed under the terms of this General
Public License. The “Program”, below, refers to any such program or work, and
a “work based on the Program” means either the Program or any derivative work
under copyright law: that is to say, a work containing the Program or a portion of
it, either verbatim or with modifications and/or translated into another language.
(Hereinafter, translation is included without limitation in the term “modification”.)
Each licensee is addressed as “you”.
Activities other than copying, distribution and modification are not covered by
this License; they are outside its scope. The act of running the Program is not
restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running
the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program’s source code as
you receive it, in any medium, provided that you conspicuously and appropriately
publish on each copy an appropriate copyright notice and disclaimer of warranty;
keep intact all the notices that refer to this License and to the absence of any
warranty; and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at
your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus
forming a work based on the Program, and copy and distribute such modifications
or work under the terms of Section 1 above, provided that you also meet all of
these conditions:
a) You must cause the modified files to carry prominent notices stating that you
changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or
in part contains or is derived from the Program or any part thereof, to be
licensed as a whole at no charge to all third parties under the terms of this
License.
c) If the modified program normally reads commands interactively when run,
you must cause it, when started running for such interactive use in the most
ordinary way, to print or display an announcement including an appropriate
copyright notice and a notice that there is no warranty (or else, saying that
you provide a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this License.
(Exception: if the Program itself is interactive but does not normally print
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
220
Appendix I. Licenses
such an announcement, your work based on the Program is not required to
print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections
of that work are not derived from the Program, and can be reasonably considered
independent and separate works in themselves, then this License, and its terms,
do not apply to those sections when you distribute them as separate works. But
when you distribute the same sections as part of a whole which is a work based on
the Program, the distribution of the whole must be on the terms of this License,
whose permissions for other licensees extend to the entire whole, and thus to each
and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to
work written entirely by you; rather, the intent is to exercise the right to control
the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with
the Program (or with a work based on the Program) on a volume of a storage or
distribution medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section
2) in object code or executable form under the terms of Sections 1 and 2 above
provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code,
which must be distributed under the terms of Sections 1 and 2 above on a
medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any
third party, for a charge no more than your cost of physically performing
source distribution, a complete machine-readable copy of the corresponding
source code, to be distributed under the terms of Sections 1 and 2 above on
a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute
corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or
executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making
modifications to it. For an executable work, complete source code means all the
source code for all modules it contains, plus any associated interface definition files,
plus the scripts used to control compilation and installation of the executable.
However, as a special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary form) with the
major components (compiler, kernel, and so on) of the operating system on which
the executable runs, unless that component itself accompanies the executable.
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
221
Appendix I. Licenses
If distribution of executable or object code is made by offering access to copy from
a designated place, then offering equivalent access to copy the source code from
the same place counts as distribution of the source code, even though third parties
are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your
rights under this License. However, parties who have received copies, or rights,
from you under this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However,
nothing else grants you permission to modify or distribute the Program or its
derivative works. These actions are prohibited by law if you do not accept this
License. Therefore, by modifying or distributing the Program (or any work based
on the Program), you indicate your acceptance of this License to do so, and all its
terms and conditions for copying, distributing or modifying the Program or works
based on it.
6. Each time you redistribute the Program (or any work based on the Program),
the recipient automatically receives a license from the original licensor to copy,
distribute or modify the Program subject to these terms and conditions. You may
not impose any further restrictions on the recipients’ exercise of the rights granted
herein. You are not responsible for enforcing compliance by third parties to this
License.
7. If, as a consequence of a court judgment or allegation of patent infringement or
for any other reason (not limited to patent issues), conditions are imposed on you
(whether by court order, agreement or otherwise) that contradict the conditions
of this License, they do not excuse you from the conditions of this License. If
you cannot distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you may not
distribute the Program at all. For example, if a patent license would not permit
royalty-free redistribution of the Program by all those who receive copies directly
or indirectly through you, then the only way you could satisfy both it and this
License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular
circumstance, the balance of the section is intended to apply and the section as a
whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other
property right claims or to contest validity of any such claims; this section has the
sole purpose of protecting the integrity of the free software distribution system,
which is implemented by public license practices. Many people have made generous
contributions to the wide range of software distributed through that system in
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
222
Appendix I. Licenses
reliance on consistent application of that system; it is up to the author/donor to
decide if he or she is willing to distribute software through any other system and
a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either
by patents or by copyrighted interfaces, the original copyright holder who places
the Program under this License may add an explicit geographical distribution
limitation excluding those countries, so that distribution is permitted only in or
among countries not thus excluded. In such case, this License incorporates the
limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the
General Public License from time to time. Such new versions will be similar in
spirit to the present version, but may differ in detail to address new problems or
concerns.
Each version is given a distinguishing version number. If the Program specifies
a version number of this License which applies to it and “any later version”, you
have the option of following the terms and conditions either of that version or of
any later version published by the Free Software Foundation. If the Program does
not specify a version number of this License, you may choose any version ever
published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose
distribution conditions are different, write to the author to ask for permission. For
software which is copyrighted by the Free Software Foundation, write to the Free
Software Foundation; we sometimes make exceptions for this. Our decision will be
guided by the two goals of preserving the free status of all derivatives of our free
software and of promoting the sharing and reuse of software generally.
No Warranty
11. Because the program is licensed free of charge, there is no warranty
for the program, to the extent permitted by applicable law. Except
when otherwise stated in writing the copyright holders and/or other
parties provide the program “as is” without warranty of any kind,
either expressed or implied, including, but not limited to, the implied
warranties of merchantability and fitness for a particular purpose.
The entire risk as to the quality and performance of the program is
with you. Should the program prove defective, you assume the cost
of all necessary servicing, repair or correction.
12. In no event unless required by applicable law or agreed to in writing will any copyright holder, or any other party who may modify
The Rockbox manual
(version rUnversioned directory-141114)
Samsung YH-820
223
Appendix I. Licenses
and/or redistribute the program as permitted above, be liable to
you for damages, including any general, special, incidental or consequential damages arising out of the use or inability to use the
program (including but not limited to loss of data or data being
rendered inaccurate or losses sustained by you or third parties or a
failure of the program to operate with any other programs), even
if such holder or other party has been advised of the possibility of
such damages.
End of Terms and Conditions
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to
the public, the best way to achieve this is to make it free software which everyone can
redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to
the start of each source file to most effectively convey the exclusion of warranty; and
each file should have at least the “copyright” line and a pointer to where the full notice
is found.
<one line to give the program’s name and a brief idea of what it does.>
Copyright (C) <year> <name of author>
This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free
Software Foundation; either version 2 of the License, or (at your option) any
later version.
This program is distributed in the hope that it will be useful, but WITHOUT
ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General
Public License for more details.
You should have received a copy of the GNU General Public License along
with this program; if not, write to the Free Software Foundation, Inc., 51
Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in
an interactive mode:
Gnomovision version 69, Copyright (C) <year> <name of author>
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type

Appendix I. Licenses
‘show w’.
This is free software, and you are welcome to redistribute it under certain
conditions; type ‘show c’ for details.
The hypothetical commands show w and show c should show the appropriate parts
of the General Public License. Of course, the commands you use may be called something other than show w and show c; they could even be mouse-clicks or menu items—
whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if
any, to sign a “copyright disclaimer” for the program, if necessary. Here is a sample;
alter the names:

This General Public License does not permit incorporating your program into proprietary programs. If your program is a subroutine library, you may consider it more useful
to permit linking proprietary applications with the library. If this is what you want to
do, use the GNU Library General Public License instead of this License.
