What's New in Release 3.12.0
The following features were introduced or in some cases enhanced in release 3.12.0. For a description of new and
changed features in previous releases refer to Releases and Features .
New Streaming Features
RTMP live streaming
Your VGADVI Recorder Pro can now stream live video to a content delivery network using Real Time Messaging
Protocol (RTMP). In addition to providing high performance streaming of audio and video, when you stream your
content using RTMP, you reduce system resource usage as well as enhance your viewer's experience.
When setting your CDN, you now have a choice between streaming with RTSP announcement or RTMP push. Both
RTSP and RTMP can be used for live streaming, however not all CDNs or media servers support both formats.
See Stream content using HTTP or RTSP.
SAP Announce
Your VGADVI Recorder Pro allows you to advertise your stream over a local network using SAP Announce. To use this
feature, your stream must be setup to use UDP streaming. Local viewers can view the stream using a software or
hardware media player. Viewers are presented with a list of available channels, similar to a television listing. Viewers
need only click on a stream or channel and the video is streamed to their desktop, mobile or tablet.
See Stream content using multicast streaming.
Layout and Branding Improvements
Enhanced layout for multiple source channels
You can customize your output stream by adding a customized background image to your multiple source channel.
You can create a background that is consistent with your corporate branding and easily apply the background to your
video stream.
See Add a customized background to a multi-view channel.
Data Redundancy and Fault Tolerance Improvements
RAID 10 support
For systems configured with at least 4 storage disks, RAID 10 is now supported.
Enhanced Internal Storage Diagnostics
You can now check if storage disks are configured for RAID, the RAID configuration level, and RAID array status.

Welcome
Welcome, and thank you for buying Epiphan’s VGADVI Recorder Pro™. This guide will help you configure your new
system. The product comes into two styles, read through the overview section if you’re not sure which one you have.
This guide refers to either the compact or the rackmount server when there is a difference, or specifies system when
the details are the same.
To get started, review the VGADVI Recorder Pro Overview and What's in the Box? sections. Next, a Quick Start guide
walks you through the basic steps to get a single video (and optional audio) source configured as a streamable,
recordable output from the VGADVI Recorder Pro.
Following the quick start section, a set of task-based procedures help you to tweak the system exactly how you want it.
These procedures are broken into seven categories: Setup, Sources, Channels , Stream, Record, View, and Maintenance.
About this Guide
Warnings are depicted as follows.
This is a warning.
Tips and Notes are depicted as follows.
This is a tip.
Throughout this guide there are situations where more than one solution will complete a task. In those cases the
guide describes the simplest or most common variation first.
VGADVI Recorder Pro Overview
VGADVI Recorder Pro is a professional audio/video streaming system that captures, synchronizes and records up to
four video sources and up to three audio sources. Epiphan’s VGADVI Recorder Pro captures video signals at resolutions
up to 2048×2048 with rates of up to 80 frames per second.
This versatile system has a variety of options enabling you to create and configure any number of streaming channels.
You can choose to stream (or record) a single channel at once or a configuration of synchronized channels with
picture-in-picture or picture-with-picture multiplexing selections.
VGADVI Recorder Pro comes in a total of four styles to meet your needs. Two HD models support resolutions up to
1920×1200 and two DL models support resolutions up to 2560×1600 or 2048×2048 (2k resolutions). Each of the HD and
DL models is available in a compact, portable server or a 2U rackmount server. The rackmount systems offer more input
connections and storage space. The following table outlines the differences in connections and storage space offered.

Quick Start
This section helps you get up and running quickly with your VGADVI Recorder Pro
l Step 1: Physical Setup and Power On
l Step 2: Admin Discovery and Login
l Step 3: Setup the Video Source
l Step 4: Configure the Channel
l Step 5: Testing the Stream
l Step 6: Recording the Stream
Before you get started, make sure you have:
l an HD source (i.e. a computer, a tablet, or a phone)
l the appropriate cables or adapters to convert the output to DVI (if needed)
l optionally, an audio source such as a microphone or the headphone jack from a laptop (note that the audio
signal sent over HDMI cables is not supported)
l ideally, a network with Dynamic Host Configuration Protocol (DHCP)
l a computer with a web browser connected to the same network (this is referred to as the “admin” computer in
the steps below)
These instructions include steps for setting up and configuring audio. Skip these optional steps if you do
not want to configure an audio source at this time.
Step 1: Physical Setup and Power On
Complete the following steps to prepare and power on the system. Refer to the Front and Back Panel View section for
your system to locate the appropriate input ports.
1. Turn on your HD source and connect the output cable to a DVI-I port on the back of the system.
2. (optional) Attach a 3.5 mm audio cable from your audio source to the system’s audio input port (blue port on
the back of the system).
3. Connect the Ethernet cable to the VGADVI Recorder Pro. Connect the Ethernet cable to your network.
4. Attach the power cable to the system and plug it into a power source.
5. Press the power button on the front panel to turn on the system.
6. Wait for the VGADVI Recorder Pro to complete the power up sequence. The power LED illuminates and the hard
drive LED flashes during start up.
Step 2: Admin Discovery and Login
The VGADVI Recorder Pro is managed from a web interface. This interface acts as a configuration utility and system
monitor. The first time you access the web interface you will not know the IP address of the system.
The steps below use DNS-based service discovery (a type of zero-configuration networking) to access the system.
Depending on the operating system on your admin computer you may need to install some software before you can
used DNS-based discovery.
Table 6 Installing Bonjour Print Services
System
Action Needed
Microsoft Windows
You must install Bonjour Print Services:
1. Use the following URL - http://support.apple.com/kb/DL999
2. Click Download.
3. Follow the system prompts to download and install the application.
Mac OS X
The Bonjour software used for service discovery is built in to the Mac OS. No special actions
needed.
Linux
The Avahi implementation used for DNS-based discovery is shipped with most Linux
distributions. If necessary, check with your administrator to ensure you have the Avahi
package installed.
This quick start is meant for systems that support DHCP and DNS, however if your system does not support
these mechanisms, refer to Connect to the Admin Interface for other discovery mechanisms. Return to
step 3 below you have completed setting up a static IP address for the VGADVI Recorder Pro.
You are able to access the system web interface on the local network by specifying its serial number in a web browser
on your admin computer.
1. Find the system’s serial number. It is printed on a sticker on the back of the unit.
2. Type the following string into the address bar of your web browser on your admin computer (where <serial> is
the serial number of your VGADVI Recorder Pro):
http://<serial>.local/admin
For example: http://95dd40d5.local/admin
3. Enter the user name and password then click OK. The administrative user is ‘admin’. Initially no password is set.
To set a password follow the procedure outlined in Setting and Changing User Passwords.
4. Optionally, navigate to the Network link under the Configuration heading and note the IP address of the
system.
Step 3: Setup the Video Source
Each video input on the back of the system is a frame grabber.
The web interface has a pre-configured list of the frame grabbers in the Sources section. Each frame grabber has one
DVI port, one S-Video port, and one audio port. The sources are listed by their frame grabber serial number.
DVI ports are listed with the suffix .vga, S-Video inputs are listed with the suffix .video, and audio inputs are listed with
the suffix _analog.
The serial numbers for your system will not be the same as the examples shown below.
1. From the web interface, scroll to the Sources section
2. For Compact Servers: Click on the DVI source (named with .vga as the suffix) and check the video preview that
appears on right side of the screen.
For Rackmount Servers: Find the DVI source that you have connected by selecting each DVI source (named with
.vga as the suffix) and verifying if the preview on the right side of the screen reflects your source material.
3. Make note of the name of the source, or optionally, change the source name to reflect the data it is capturing.
To rename the input source:
a. Click on the source name at the top of the source configuration window. The name text becomes red.
b. Edit the name. The following characters are supported: a-z; A-Z; 0-9; + (plus); - (hyphen); _ (underscore); ,
(comma), . (period); ~ (tilde); # (hash); [ ]; ( ). Although spaces are also supported, it is suggested you use
underscores to separate words.
c. Press Enter on the keyboard. The name is updated at the top of the screen and in the list of sources at the
left side.
4. Optionally, add the audio source:
a. Scroll to the Sources section again and select the audio source that is prefixed by the word audio (i.e.
aduio ALC892 Analog); the audio configuration page appears.
b. From the Input source drop-down list, select Line for the blue port at the back of the system.
c. Click Apply.
Source setup is complete. The system automatically detected and adjusted the image capture settings at start up and
will continue to adjust every 60 seconds during operation (interval is configurable). The system’s goal is to produce the
best quality captured image given the source equipment used. Generally no further configuration tweaks are needed.
Step 4: Configure the Channel
Now that you have confirmed the system sees your source it is time to add and configure a channel for output of your
source. Channels expose your sources to your streaming users and prepare the sources for recording.
By default, when you add a channel, the system names it the same name as its source. If you changed the source name
in previous steps, your new channel's name will reflect the new name.
To add a channel for your source:
1. In the web interface, click Add channel from the Channels section; a new channel is created and the channel
configuration page opens.
2. From the Use video source drop-down list, select your source.
3. Click Apply.
To review and configure the channel:
1. From the web interface, scroll to the Channels section
2. Click the link for your channel; the channel expands.
3. Click Stream Setup for your channel
4. No need to change anything right now. Review some of the default settings. The four most useful settings to
know about are codec, frame size, frame rate and bitrate.
a. The codec is set to H.264 by default.
b. The frame size should reflect the resolution provided by your source. You can set it to something different
by typing in the fields or selecting an option from the different sizes shown. Scaling the image (making it
larger, smaller, or different aspect ratio) takes some processing power, so it’s always best to leave this at
the value detected by the system unless you know it is wrong or know you need to scale the size.
c. The frame rate limit is set to 30. This means the system won’t spend extra computing time to attempt to
receive more than 30 frames per second. For perspective, NTSC TV signals use 24 frames per second and
most hand-drawn animations show only 12 unique frames per second.
d. The bitrate is set to 4000 kbit/s. This is a good starting point. Raising this value uses more system
processing power and more bandwidth.
5. Click Channel Status for your channel.
6. Notice the Stream Info section has an item named Video that reflects the four settings reviewed in prior steps
(the frame rate is specified as <resolution size>@30 for 30 frames per second). It also provides an indication of
the current actual frame rate.
You may now optionally add audio to your channel:
7. Click Media Sources for your channel; the media source page is displayed.
8. Select the audio source to which you connected your 3.5mm audio cable. If you connected to the blue line-in on
the back of the system, the audio source is the audio source without a frame grabber serial number.
9. Click Apply.
10. Click Stream Setup for your channel; the stream setup page is displayed.
11. Scroll to the bottom of the stream setup and click the Enable audio checkbox.
12. Leave the default MP3 format and audio bitrate.
13. Click Apply.
Step 5: Testing the Stream
The Channel Status page contains a link to the live broadcast stream for your channel.
To preview the channel in a browser:
1. From the web interface, scroll to the Channels section.
2. Click the link for your channel.
3. Click the Channel Status link for your channel.
4. Right-click on the Live broadcast link for your channel and select Open in a new tab or Open in a new
window.
5. The new tab or window opens with the stream displayed.
a. If the signal is not detected, reseat the DVI cable connections and try again.
Your stream setup is complete. Since most of the steps are pre-configured; you are up and running with a stream very
quickly. You can share the live broadcast link with your users.
Step 6: Recording the Stream
The stream is set up, you can begin to record the stream.
To record the stream:
1. From the web interface, scroll to the Channels section.
2. Click Files Archive for your channel; the files archive page is displayed.
3. Click the red Start button; the text at the top of the screen changes to indicate the recording is starting, then
indicates the length of time since the recording started.
4. Click the black Stop button; the recorder stops.
5. Refresh the page by clicking Files Archive again; the page reloads and a file list appears that shows your newly
recorded stream snippet.
6. Click the file name to download and view your recording.
What’s Next?

Setting and Changing User Passwords
The VGADVI Recorder Pro's three static users are: admin, operator and viewer.
None of the accounts have passwords assigned by default, but since both the admin and the operator user
have access to the web admin interface, you should always have a password for both admin and operator
accounts. Refer to your system administrator for your organization’s specific password requirements.
Passwords are case sensitive and can use all alpha-numeric keys in the ASCII range. Your password can be up
to 255 characters long, but should not include any spaces.
Setting a user’s password causes the user to be logged out. Be ready to log back in with the new
admin password or have operators and viewers log in with the appropriate new password. Viewers
may need to refresh their browser window or press play in their media player.
If you lose the admin password, refer to the section Overcoming Lost Passwords.
To set a user password:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Access passwords link in the Configuration menu; the password configuration page opens.
4. Highlight and delete the current password for your selected user (the password is currently masked as
dots).
For security reasons, the current password appears as eight dots regardless of password
length, and even if there is no password set.
5. Highlight and delete the confirmation password for the selected user.
6. Select the user’s password field and type a new password for the user.
24
VGADVI Recorder Pro User Guide

Description/Options
NTP
Network Time Protocol (NTP) is used for clock synchronization over the internet.
There are many publicly available NTP servers you can use, or your company may
have its own NTP server. For more information about NTP and to find NTP servers,
refer to http://support.ntp.org/bin/view/Servers/WebHome.
RDATE
RDATE is a tool for querying the current time from the network. It is generally
considered obsolete and has been replaced by NTP.
PTP v1
The Precision Time Protocol (PTP) is used for clock synchronization over the
internet. It has clock accuracy in the sub-microsecond range, making it more
granular than NTP.
6. Tailor the synchronization protocol with the required parameters as described below.
7. If NTP is selected:
a. Enter the IP address or server name for the NTP server in the Server IP Address field.
NTP uses UDP packets and port 123. If the system is behind a firewall and accessing an
external NTP server, UDP packets must be permitted on port 123.
8. If RDATE is selected:
a. Enter the IP address or server name for the RDATE server in the Server IP Address field.
b. Select an update interval from the drop down box.

1-5 Restrict Viewers by IP Address
1-5 Restrict Viewers by IP Address
The VGADVI Recorder Pro permits you to restrict which computers can access broadcasts by building a list of
allowed and/or denied IP addresses.
IP address restriction is valid for the viewer only and does not affect the web interface or the
mobile configuration interface.
If your viewer account has a password, your viewers must connect to the system from a computer (or gateway)
with a permitted IP address and must also supply the username and password before they can view the
broadcast.
IP Address restriction is not configurable per channel. Restrictions affect all broadcasts / streams
from the system.
To restrict access by IP address you need to know the IP addresses, or range of addresses for your viewers. By
default all IP addresses are allowed to connect to the broadcast.
If you’re not familiar with creating allow/deny lists, refer to the examples below this procedure for assistance
with crafting your lists.
To restrict viewers by IP address:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Access passwords link in the Configuration menu; the password configuration page opens.
4. Type allowed IP addresses or address ranges in the Allow IP’s field. Separate addresses with a comma.
5. Type denied IP addresses or address ranges in the Deny IP’s field. Separate addresses with a comma.
6. Click Apply.
If a user attempts to connect to the stream from a disallowed IP address, access is denied. If connecting by
internet browser, the message "IP address rejected." is displayed.
The following table describes the applicable fields.

Table 15 IP Based Restriction Fields
Label
Description/Options
Allow IP's
Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are permitted to view broadcasts from the
system, provided their IP address is not in the Deny IP’s list.
To allow all (except IP addresses in the deny list, if any), leave the field blank.
You can use the Allow list by itself, or in conjunction with the Deny IP’s list as an exception
to a rule in the allow list.
Deny IP's
Enter individual IP Addresses or IP Address ranges, separated by commas. To specify a
range, use a hyphen (-). Optional spaces improve readability.
Users connecting from addresses in this list are not allowed to view broadcasts from the
system, unless their IP address is in the Allow IP’s list. If a specific IP address is in both lists,
access to the stream is denied.
You can use the Deny list by itself, or in conjunction with the Allow IP’s list as an exception
to a rule in the allow list.
Examples
Allow List with Distinct IP Addresses
The simplest allow/deny list is to use the list of known IP addresses to craft a list of allowed IP addresses. All
other addresses are denied access to the broadcast.
For example if your system is accessible on your local area network (LAN) and you want to make sure only the
CEO’s specific desktop, laptop and tablet computers (with IP Addresses 192.168.1.50, 192.168.1.51, and
192.165.1.75, respectively) can connect to the broadcast, construct the following allow list:
Allow: 192.168.1.50, 192.168.1.51, 192.168.1.75
Allow List with a Range of IP Addresses
Sometimes you’ll want a range of computer IP addresses to connect to your system. This may happen when
you have one range of IP addresses assigned to desktop computers (i.e. in the range 192.168.1.1 to
192.168.1.100) and another range assigned to boardroom computers (i.e. the range 192.168.1.200 to
192.168.1.250). If you only want the boardroom computers to connect to broadcasts from the system you can
40
VGADVI Recorder Pro User Guide
1-5 Restrict Viewers by IP Address
specify the range of boardroom IP addresses rather than needing to type in each individual address. The allow
list looks as follows:
Allow: 192.168.1.200-192.168.1.250
Note that we could have specified two of the IP addresses in the previous example as a range.
Allow List with a Range of IP Addresses and One or More Specific IP
Addresses
Putting the first two examples together, we want to permit access to IP addresses in the range of boardroom
computers (192.168.1.200-192.168.1.250) and also want to add the desktop, laptop and tablet computers of the
CEO (IP addresses 192.168.1.50, 192.168.1.51, and 192.168.1.75, respectively). Note the first two IP addresses are
consecutive, so they can be added as a second range. Add these IP addresses to the list as follows:
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Your list can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny List with Distinct IP Addresses
Another simple allow/deny list is to use the list of known IP addresses to list specific denied IP addresses. All
other addresses are allowed access to the broadcast.
For example imagine your system is accessible on your local area network (LAN) and you want to allow any
computer on the LAN can access the stream except your publicly-accessible boardroom (with IP address
192.168.1.211). You can use the following deny list (leave the allow list empty) to permit all computers except
the boardroom computer:
Deny: 192.168.1.211
As with Allow lists, your deny list can specify a range of IP addresses, and can specify multiple ranges or distinct
IP addresses in a comma-separated list.
Allow List with a Range of IP Addresses, Distinct IP Addresses, and an
Exception
Building on the previous examples, consider the situation where you want the CEO’s computers (192.168.1.50,
192.168.1.51, 192.168.75) and all boardroom computers (192.168.1.200-192.168.1.250) to access the broadcast,
with the exception of the public boardroom computer (192.168.1.211). Use both allow and deny lists to create
the rule as follows:
41
VGADVI Recorder Pro User Guide
1-5 Restrict Viewers by IP Address
Allow: 192.168.1.200-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75
Deny: 192.168.1.211
Both lists can have multiple ranges and multiple distinct IP addresses, provided they are separated by commas.
Deny List with a Range of IP Addresses
Converse to the previous examples, consider the situation where you want every computer on the network to
access the broadcast, with the exception of the CEO’s desktop, laptop, and tablet computers. Additionally,
boardroom computers should not be permitted with the exception of the cafeteria computer (IP address
192.168.1.222).
The deny list is an "exception" list for the allow list. So to craft the rule described above we need to allow all the
computers in the local subnet, then deny specific sub-ranges including two groups of boardroom computers
ensuring the cafeteria computer's IP address is not in the deny list:
Allow: 192.168.1.1-192.168.1.250
Deny: 192.168.1.200-192.168.1.221, 192.168.1.223-192.168.1.250, 192.168.1.50-192.168.1.51, 192.168.1.75

PART 2: Sources
PART 2: Sources
Now that you know how to connect to the admin interface, you are ready to configure your input sources. The
following sections provide an overview of the types of sources you can connect to your VGADVI Recorder Pro
and how to configure each source.
The following topics are covered:
l Identify sources
l Configure a video source
l Configure an audio source
l Fine-tune source configuration
43
VGADVI Recorder Pro User Guide
2-1 Identify sources
2-1 Identify sources
A source can be an image, video, or audio from a camera, a computer screen or any device that provides a VGA,
DVI, HDMI, S-Video and audio signal output. Prior to powering up the VGADVI Recorder Pro connect the input
sources to the following input ports on the system:
Table 16 Cable and port connections
Cable
Input Port
connect VGA, HDMI or DVl (dual or single link,
depending on your system)
DVI port
connect composite or S-video source
S-Video port
connect audio
Audio Input port
The web interface automatically discovers all input sources and displays them in the Sources section of the web
admin interface.
Each video input on the back of the system is a frame grabber. Input sources are identified by their frame
grabber serial number. Each frame grabber has one DVI port, one S-Video port, and one audio port. DVI ports
are listed with the suffix .vga, S-Video inputs are listed with the suffix .video, and audio inputs are identified by
the word audio. The input sources are immediately capable of displaying captured images, so it is a good
practice to view the images from each source to confirm what is captured.
When a source is connected, the system automatically detects and adjusts the image capture settings at start
up and continues to adjust every 60 seconds during operation (interval is configurable). The system’s goal is to
produce the best quality captured image given the source equipment used. Generally no further configuration
is needed.

Video is too bright, too dark or washed out
If the video from the source is too light, too dark or washed out, use the offset and gain controls together to
optimize image quality. Increasing the gain amplifies weak signals but also increases noise, you must balance
offset and gain values to achieve the best quality image.
Adjust these settings by the smallest values possible; compensate for a large change to one by making a large
change to the other. Setting both offset and gain to high values can result in poor video quality.

Remove the combing effect on images
When frames are interlaced, artifacts from one frame may appear on the next frame. This occurs when a fast
motion video is interlaced. Since each frame is captured from a different point in time, the action captured in
one frame is carried over to the next frame. The result is a blurred image and horizontal lines running across
the video.

PART 3: Channels
Channels organize and display content captured from DVI, VGA, HDMI, audio and camera input sources. A
channel can be set up to display the content from one input source, or may capture, stream and record
content from multiple input sources. You can identify your channel by adding a corporate logo, company
information, corporate color and time stamps.
Through channel configuration and fine tuning you can maximize your stream quality, minimize your
processing requirements and bandwidth and specify how the video is presented and streamed to a sharing
destination/viewer.

Create a single source channel
A single source channel displays the output from one source in one viewing screen. By default, channels are
automatically configured with the same name as their source. If you change the name of a source, the channel
name will reflect the new source name. Best practice is to rename the sources as required and leave the
channels to reflect the name. However, to change a channel’s name go to Rename a channel In this section you
can choose settings that maximize your stream quality, while minimizing your processing requirements and
bandwidth by adjusting frame rate, resolution and bit rate.

10. Click the Stream Setup link for your channel; the stream configuration page opens.
11. If you're not sure what Codec to pick, keep the default, H.264. For help selecting a codec, refer to Finetune channel configuration
12. Keep the default video encoding preset and video encoding profile for help selecting these values,
refer to Fine-tune channel configuration
13. Check the checkbox for HTTP Live Streaming to enable HLS streaming. When this feature is enabled
the Stream info section on the Channel Status page displays an HLS stream link. Using the HLS link,
viewers can access the stream using a tablet or smart phone device.
14. Set the Frame size to reflect the same dimensions as your source or as sharing destination. Default
values cover popular resolutions of cameras and display devices such as monitors or choose one of the
following:
a. Type a frame size in the field; or
b. Select an option from the sizes shown, the dimensions will appear in the frame size field.
Making the dimensions larger, smaller, or a different aspect ratio than the source takes
some processing power, so it’s always best to leave at the value detected by the system
unless you want to specify a particular size.
15. Click on the Key frame interval drop-down box to choose how often a key frame (a frame that contains
all the pixels) is used when streaming the video. The longer the key frame interval the smaller the video
file size, and vice versa. The higher the value the faster a user moves through the frames of the video
when using the search function of their media player. For more information on adjusting this feature to
reduce bandwidth and system resources, see Fine-tune channel configuration .

16. Change the Limit frame rate. The default should be adequate in most applications. While decreasing
the limit may improve system performance, you may need to test different values to balance video
smoothness and processing power.
17. Increase or decrease image quality by increasing or decreasing the target Bitrate value when H.264 and
MPEG4 codecs are used. Video with a high level of motion and high resolution, such as a sporting event,
requires a high bitrate.
Raising this value uses more system processing power and bandwidth.

In addition to adjusting typical features such as frame rate, resolution and bit rate to reduce bandwidth and
system resource usage, choose the following settings to maximize your stream quality, while minimizing your
processing requirements and bandwidth:
l Choose a codec to maximize your stream quality
l Codec and file format compatibility
l Adjust video quality
l Upscale or downscale your video image
l Control the matte (black bars) in the video output
l Unstretch the output video
l Limit the frame rate
l Adjust key frame interval
Choose a codec to maximize your stream quality
Before you begin recording and streaming content from a channel, you must select the codec that will be used
to compress the channel’s video and audio content. Deciding on which codec to use depends on how you
prioritize the following criteria:
l Compatibility with streaming formats and file playback options
l Size of the compressed file
l Compression speed
l Image quality
For example, if you require a high quality image, the trade-off might be a larger file size, or slower compression
speed. If you require live streaming and therefore cannot tolerate slow compression, the trade-off might be a
lower resolution. The table below highlights the advantages and disadvantages of supported codecs.
Once you select video and audio codecs a list of available video format and standards specific to the selected
codec is generated and displayed. You can provide the URLs and files to participants to view the broadcast, see

Adjust video quality
After sources are connected and channels are created, adjustments can be made to address the different
bandwidth and devices used by the sharing destinations. Ideally you want to choose formats that will reach the
majority of your participants.
Default values have been carefully selected to provide maximum performance in most
environments. In most cases it is not necessary to change the encoding settings.
To encode your video stream:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, select a channel; the menu expands.
4. Click Stream setup: a Stream setup page opens.

Default
Choose this option when video is viewed for broadcast and disk storage
applications, particularly for high definition television application such as Blu-ray
disk storage format and HDTV broadcast service.
Video encoding profile and preset can be set when H.264 codec is selected.
7. Set the Rate Control mode when H.264 and MPEG4 codecs are set. The values define how strictly the
codec adheres to the specified bitrate. Choose one of the following options from the Rate control mode
drop-down menu.
Value
Description
Relaxed
Choose Relaxed when streaming multimedia content and there is available
bandwidth, the quality of the multimedia stream must be constant and the bit
rate can vary.
Balanced
Choose Balanced when streaming multimedia content that has periods of high
and low bit rates. The target bit rate is met by averaging the bit rate.
Strong
Choose Strong when streaming multimedia content when limited bandwidth is
available and a constant frame rate is required. There may be a decrease in video
quality if there is a lot of motion.
8. Click Apply.
Upscale or downscale your video image
If your source input is larger than your desired output frame size or if you want to stream a less bandwidthhungry version of the content, you can downscale the source by specifying a frame size that uses the same
aspect ratio. By contrast you can also enlarge the image by selecting a value that is larger than the source
resolution.
The VGADVI Recorder Pro conveniently provides a list of common aspect ratios and different frame sizes at
each ratio on the Stream Setup page.
71
VGADVI Recorder Pro User Guide
3-3 Fine-tune channel configuration
For example:
l input signal resolution is 1920×1080 (a 16:9 aspect ratio)
l select another 16:9 frame size such as 1280×720
The smaller frame size will downscale the image and use less bandwidth to transmit.
If you select a frame size that is not the same aspect ratio as your source, the result is one of having a matte (bars) appear around the image, or the image is stretched. See Control the matte (black bars) in the video
output for details.
Resizing a video can be more resource intensive rather than leaving the video at a native
resolution. Although you can change the resolution at the VGADVI Recorder Pro level, it is less of a
burden on your system resources if you can change the resolution at the source level.
To change the frame size of your video, follow the steps below.
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select a channel; the menu expands.
4. Click Stream Setup; the stream setup page opens.
5. Scroll to the frame size parameter.
6. Choose a resolution from the links on the right, or type a frame size into the Frame size fields.
7. Click Apply.
Control the matte (black bars) in the video output
By default, the VGADVI Recorder Pro makes sure that the aspect ratio of input signals is preserved when the
output is streamed. If an input video signal doesn't match the encoded frame aspect ratio, bars are added to
the sides or top and bottom of the encoded stream when the output is streamed and recorded. The color of
72
VGADVI Recorder Pro User Guide
3-3 Fine-tune channel configuration
the bars is defined by the Background color selected on the Stream Setup page. See Select the background
color for your channel.
For example:
l Input signal resolution is 720×480 (a 3:2 aspect ratio)
l encoded resolution is 640×480 (a 4:3 aspect ratio that is narrower than the input resolution)
Borders are added to the top and bottom of the image to preserve the wider ratio of the input.
For example:
l Input signal resolution is 720×480 (a 3:2 aspect ratio)
l encoded resolution is 1280×800 (a 16:10 aspect ratio that is wider than the input resolution)
Borders are added to the left and right of the image to preserve the narrower ratio of the input.
73
VGADVI Recorder Pro User Guide
3-3 Fine-tune channel configuration
If you are seeing bars on your image but would rather have the image fill the whole screen you have to options:
1. Change the output frame size to match the aspect ratio of the input.
2. Stretch the image to fit the output frame size aspect ratio.
These two options are described below.
Match the output frame size to the aspect ratio of the source signal
To change the output frame size to match the aspect ratio of the source:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select a channel; the menu expands.
4. Click Media Sources; the media sources page opens.
5. Find the name of the media source used for the channel.
6. Click this source under the Sources menu.
7. Make note of the input signal resolution.
8. Click the channel's Stream Setup; the stream setup page opens.
9. Scroll to the frame size parameter.
10. Look for the source aspect ratio in the list of aspect ratios provided.
a. If the source resolution is on the list, choose another resolution on the same line (i.e. with the
same aspect ratio).
b. If the source resolution is not on the list, use a calculator to get a factor of the source resolution
and enter it in the Frame size fields.
11. Click Apply.

Stretch the image
To remove the matte (black bars) by stretching the image to fit your output frame size:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select a channel; the channel menu expands.
4. Click Media Sources; the media sources page opens.
5. Deselect Keep aspect ratio.
6. Click Apply.
Unstretch the output video
By default, the VGADVI Recorder Pro makes sure that the aspect ratio of input signals is preserved when the
output is streamed. If this default was overridden or if the channel was created in a version of the software
earlier than 3.11.0, the image is stretched to match the output frame size. The effect may be subtle and may not
be problematic for you, but if you want to resolve this it is very simple to do.
To preserve the source aspect ratio:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Click Media Sources; the media sources page opens.
4. Select Keep aspect ratio.
5. Click Apply.
75
VGADVI Recorder Pro User Guide
3-3 Fine-tune channel configuration
Unstretching the image causes a matte (black bars) to appear on the sides or top and bottom of
the output. To remove these see Control the matte (black bars) in the video output.
Limit the frame rate
Limiting the frame rate sets a frame rate value that is lower than the maximum frame rate at which the device
can encode images (the maximum is 30). Reducing the frame rate reduces the number of images captured by
the device and reduces bandwidth usage.
The device's ability to maintain a set frame rate is based on several factors, for example:
l overall system load affects the ability for the device to process pixels;
l available bandwidth;
l the resolution value;
l the type of motion that is captured; and
l number of users accessing the stream.
When adjusting the frame rate, you may need to try different values to achieve the best outcome. The following
table provides the performance expectations when typical settings are used.
To change the frame rate:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, select a channel; the menu expands.
4. Click Stream Setup; a Stream setup page opens.
5. Enter a value in the Limit frame rate field.
6. Click Apply.
Adjust key frame interval
The key frame interval feature specifies how often a key frame (a frame that contains all the pixels) is used when
streaming the video. This setting also impacts how quickly a video moves through the frames when a viewer
uses the search function of their media player.
Increasing the number of seconds between key frames can significantly reduce your bandwidth and system
resource usage with minor impact to your video quality. A good rule of thumb is to keep the interval between 2
to 3 seconds and decrease the key frame interval as the motion increases. Try different settings and note
76

changes in the video quality. If your video quality is poor and jittery you may need to decrease the interval
between key frames. If you have unlimited bandwidth and system resources you can choose an option to
stream key frames only.
To adjust the key frame interval:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. From the web interface, select a channel; the menu expands.
4. Click Stream Setup; a Stream setup page opens.
5. Scroll to the Key frame interval drop-down menu. Choose the number of seconds before the system
streams a key frame.

Each method of streaming media has strengths and weaknesses depending on your audience location,
hardware resources and bandwidth. To help you to decide how to publish your content, you must first identify
the number of viewers and how viewers will access your content. Are you streaming live video, or recorded
video. Do you need to stream the content to one client (peer-to-peer), deliver a single stream to multiple clients
(multicast), or provide web-based streaming where multiple clients can access the broadcast (Content
Distribution Network).
The following table gives you a brief outline of the distribution options. A procedure to configure each
distribution option follows the table.
Publishing Options
Use this option to...
HTTP
Quickly stream content to viewers simultaneously. No set up is required. The
VGADVI Recorder Pro is ready to stream content as soon as it is has power
and a configured channel. No other settings are required. Your audience
need only access the URL of the broadcast and they are instantly connected.
This viewing method is ideal for a small number of viewers since streaming
uses your system resources and bandwidth. However a small amount of
overhead is used for each viewer. For more information about using a HTTP
streaming, refer to Stream content using HTTP or RTSP.
RTSP
Quickly stream content to viewers. No set up is required. The VGADVI
Recorder Pro is ready to stream content as soon as it has power and a
configured channel. No other settings are required. Your audience need
only copy and paste the URL of the stream into a media player. For more
information about using a RTSP and HTTP streaming, refer to Stream
content using HTTP or RTSP.
HTTP Live Streaming
(HLS)
Stream live over the standard HTTP port 80, making it possible to cross
firewalls and proxies that are normally accessible to other HTTP traffic and
facilitates content delivery to CDNs.
There is a 30 second delay when streaming using HLS.

Content Distribution
Network
Stream web content to many viewers simultaneously to any geographical
location. A viewer accesses the broadcast from a website using a user name
and password, if required. Using a CDN to host your broadcast is highly
scalable and makes financial sense to website owners since you do not pay
for additional server hardware or routing should your network traffic
increase or decrease.
Using a CDN to stream live content allows you to reach a large
geographically diverse audience and because CDNs perform format
conversion, the stream is platform independent.
For more information about streaming to a CDN, see Stream content using a
Content Distribution Network.
The following options are available to stream video to a CDN:
Epiphan TV - test your video stream using Epiphan’s portal
using RTSP announce - stream live video to a content delivery network
using RTMP push - stream live video to a content delivery network
RTSP and RTMP streaming provides the following advantages:
l viewers can watch the action as it unfolds;
l video quality automatically changes to adjust to changes in
bandwidth;
l reduced bandwidth usage since the player maintains a smaller buffer;
and
l viewers can scroll back through later sections of the video while the
video is streaming.

Multicast Streaming
Stream content to a multicast IP address where it can be shared with
multiple viewers within the same LAN. All viewers receive the same stream at
the same time. Similar to turning on a radio station, all listeners hear the
same music at the same time.
This delivery method relies on network equipment that supports
multicasting and is usually used in high bandwidth corporate LANs and not
on Internet-based architectures.
This delivery method is useful for training sessions, when there is a specific
timeframe when the audience will view the content. For more information
about using multicasting for streaming your content, see: Stream content
using multicast streaming
l RTP/UDP transport standard is used to stream H.264 video when
unicast or multicast streaming is used. Each viewer retrieves an SDP
file. SDP files can be stored on a streaming server, or opened by a
media player. For multicast, the destination address is
l MPEG-TS UDP transport standard is used to stream MPEG-4 video
when unicast or multicast streaming is used. Each viewer retrieves a
UDP address to add to their media player.
l MPEG-TS RTP/UDP transport standard is used to stream video when a
single port is used to stream video and audio via unicast or multicast.
Each viewer retrieves a RTP address to add to their media player.
This option can be used to stream video and audio to an IP TV or set top box
playlist.
To stream video outside of your LAN, use a CDN or configure port forwarding on your router. Refer
to your Network Administrator; network configuration is beyond the scope of this guide.
The Publish Stream feature is available when the H.264 codec is set.
Retrieve stream URLs
The quickest and simplest way to deliver your content is to send the broadcast's URL to your viewers. You can
provide separate URLs for each channel being streamed. Alternatively, one URL can be provided that includes
all streams from all input sources. The format of the URL depends on the method you used to access the
system, either through network discovery using the serial number or IP address.

Stream content using UPnP
Using the Universal Plug and Play (UPnP) networking protocol, your VGADVI Recorder Pro can be discovered
and can stream to software and hardware media players, set-top-boxes and Smart TVs with ease. If UPnP is
enabled, the system automatically establishes communication with media players on the network.
UPnP uses MPEG-TS over HTTP with the H.264 codec and MP3 or AAC audio encoding (or no audio). You can
only access live streams or recordings that meet these requirements.
For security reasons the default behavior prevents UPnP access to live streams and recorded files.
This section covers the following topics:
l Enable UPnP
l Disable UPnP
l Stream your video
l Auto-restart playback to a UPnP Device
l Change UPnP device name
Some players will not be able to access the stream or saved recordings if a view password is set. If
needed, see Removing User Passwords to clear the viewer password.
The topics in this chapter include how to enable and disable UPnP and how to control media players from the
VGADVI Recorder Pro. To choose recordings or live streams from your media player, see Viewing with UPnP .

When choosing your stream settings it is important to consider the stream content. When streaming fast
moving video it's best to choose a higher bitrate and frame rate versus streaming a slide presentation where
you can save on bandwidth and system processing by lower the bitrate and frame rate. Stream setup is a
matter of balancing quality and system resource usage.
To help you to achieve this balance the following tables list the recommended settings when streaming video
and slide content from a PC, Mac or tablet.

Recording can also be controlled via the tablet interface. See Control recording via the tablet interface.
Recording basics
While recording a channel or recorder, a new file is created each time the maximum time or size limit is met. Additionally,
when recording a multi-channel recorder or a multi-view channel, a new file is created if an additional source is added
to the recorder.
Recording is stopped if the channel, or all channels in a recorder, are made inactive by removing their source (i.e.
setting the source to "no source"). An interrupted signal to the source does not affect recording, and the recording will
include the configured No Signal image.
Each channel that has a source present uses some CPU power to encode the stream. You can avoid CPU overload by
setting up channels you intend to use but setting the source to No Source. When you are ready to use the channel
again, simply set the source and all your other configuration is already set. This doesn't apply for multi-view channels
which will always have at least one source to keep its configuration settings.
Record a channel via the web interface
Each channel has a configuration page that allows you to start, stop and configure recordings.
To start and stop channel recording:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin or operator.
3. Click the name of the desired channel; the channel menu expands.
4. Click the Files Archive link for the channel; the Files Archive page appears.
5. To Start Recording:
a. Click the Start button; the recording starts and a timer indicates how long it has been recording.
If the start button is not active, there are no active sources for this channel or recorder. Check
your inputs to ensure signals are working as expected.
b. You may browse away from the page without affecting the recording. When the page refreshes, the
channel number is displayed in red to indicate recording is underway.
c. The system continues to record this channel (and any concurrent recordings) until it is stopped. If the
system runs out of storage space, the oldest recorded file is deleted to make room for the new recording.
The recording is broken into multiple files as defined by the channel configuration. See Configure the type
and length of recording files.
6. To Stop Recording:
a. Click the Stop button on the given channel’s Files Archive page. The channel number changes to black
next time the web interface is refreshed (by clicking a link or refreshing the page).
Record with a recorder via the web interface
Recorders are stopped and started via their configuration page. Multiple recorders and channel recordings can occur
concurrently.
A new recording file is generated each time a configured source in the recorder comes online. For example if the
recorder has two configured sources but when the recording starts and only one source is active, it will start a singletrack recording. When a second source starts sending signal, the first recording file is closed and a new multi-track file
is opened. If a source that is being recorded becomes inactive, the recorder continues to record the source with the no
signal image.
The number of active sources is displayed above the recording stop/start buttons during recording.
To start and stop recorder:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin or operator.
3. Click the name of the desired recorder; the recorder configuration page appears.
4. To Start Recording:
a. Click the Start button; the recording starts and a timer indicates how long it has been recording.
b. You may browse away from the page without affecting the recording. When the page refreshes, the
recorder number is displayed in red to indicate recording is underway.
c. The system continues to record this recorder (and any concurrent recordings) until it is stopped. If the
system runs out of storage space, the oldest recorded file is deleted to make room for the new recording.
The recording is broken into multiple files as defined by the recorder configuration. See Configure
the type and length of recording files.
5. To Stop Recording:
a. Click the Stop button on the given recorder's configuration page. The recorder number changes to black
next time the web interface is refreshed (by clicking a link or refreshing the page).
Configure the type and length of recording files
By default, recorders and channels record to AVI files. When the recording reaches 30 minutes in length or a file size of
500 MB (whichever occurs first), the system closes the current recording file and opens a new one. This is done
seamlessly with no loss in recorded data.
You may find it useful to have recordings divided this way for ease of download, but you may also want to change the
recording limits to be larger or smaller to meet your individual situation.
Additionally you can configure the prefix for all recordings (the suffix is the date and time of the recording) and you can
exclude a channel or recorder’s recordings from automatic upload.
To change the recording configuration:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. For a channel recording:
a. Click the desired channel; the channel menu expands.
b. Click the Files Archive link for the channel; the Files Archive page opens.
4. For a recorder:
a. Click the desired recorder link from the Recorders section; the recorder configuration page opens.
5. Click the change link under Recorder Setup; the recorder setup section expands. (The setup page looks slightly
different for Recorders, but the options are the same.)
6. Select a time limit for the recording from the Time limit drop down.
7. Select a file size limit from the Size limit drop down.
Tip: If you don’t know what size to select, do some test recordings to get an idea of the file sizes you
can expect. If you want to guarantee the recording lasts to a given time limit, select a file size that is
far larger than you saw in your tests.
8. Select a file type from the File type drop down.
9. If desired, enter a prefix for the recordings. All new recording files for this channel or recorder will be prefixed
with the text you enter.
Tip: It’s best to avoid spaces in file names. Use underscores or hyphens to separate words.
10. If desired, click the check box to exclude this channel or recorder from automatic file uploads. (See File and
Recording Transfer for information on automatic uploads.)
11. Click Apply; the changes are saved and the recorder setup displays the new configuration.
The table below describes the options available for recording file configuration.

Viewing with UPnP
Using a software or hardware media player, you can browse for files or streams with Universal Plug and Play
(UPnP). UPnP uses MPEG-TS over HTTP with the H.264 codec and MP3 or AAC audio encoding (or no audio). You
can only access live streams or recordings that meet these requirements.
For security reasons the default behavior prevents UPnP access to live streams and recorded files.
To enable UPnP, see Stream content using UPnP
Some players cannot access the stream or saved recordings if a viewer password is set. If needed,
see Removing User Passwords to clear the viewer password.
When browsing via UPnP your VGADVI Recorder Pro is displayed by the server name you set, or it's product
serial number.
For example, when browsing from a Windows computer, you will see a list of media devices that includes the
VGADVI Recorder Pro:
154
VGADVI Recorder Pro User Guide

Live Streams
When you open the device from Windows Media Player, you'll see a list of the available channels you can stream
under the Videos tab. The channel names are the same as they are in the admin interface. From other digital
media players, the channel list can be under a Live Streams folder.
With Windows Media Player, double click to open any channel and press Play to start the stream. Using your
digital media player, select a live stream and press play.
Recorded Files
Recorded files are shown in the Recorded Files folder. Files are organized by the channel or recorder from
which they were recorded. Windows Media Player shows the recorder files side by side with the channels and
other digital media players show the recorded files in a file tree format, see below.
UPnP can also be used to directly play a recording to the digital media player, or to set a media player to
automatically play a particular live stream after reboot of the VGADVI Recorder Pro. See Stream content using
UPnP and Auto-restart playback to a UPnP Device.

Viewing with Session Announcement Protocol (SAP)
When SAP Announce is configured for a stream that uses UDP streaming, the stream is advertised over the
local network. Local viewers can view the stream using a software or hardware media player. Viewers are
presented with a list of available channels, similar to a television menu. Viewers need only click on a stream and
the video is streamed to their desktop, mobile or tablet. To configure SAP announce, go to Stream content
using multicast streaming.
Your VGADVI Recorder Pro is advertised by the metadata title, if one was configured under Stream Branding,
otherwise it is identified by it's channel identifier. For a description of how to set the metadata, refer to Add
your logo and company information to your channel.
When browsing from a VLC media player, streams are advertised by their channel identifier and are organized
by the group name. When browsing from an XBMC media player, streams are advertised by the stream's
metadata title, if configured, otherwise streams are advertised by their channel identifier.
1. Ensure the stream has SAP announcement enabled, otherwise it is not advertised in the media player's
playlist.
2. Ensure the SAP announcement IP is a multicast IP address.
3.
Some media players, for example Exterity receivers, listen for SAP announcements on a
specific multicast address 239.255.255.255. If your audience is using Exterity to view your
stream, you must change the SAP announcement IP address to 239.255.255.255.
4. Launch a media player. The following steps are based on a VLC media player and may be different for
other media players.
5. Click View from the menu; a drop-down menu opens.
6. Select Playlist. A Playlist window opens. The right-hand panel indicates the playlist is empty.
7. From the side menu, click Network streams (SAP). The playlist is populated with all streams in your
network that are SAP announcement enabled. If you specified a Group Name when you configured the
publish stream the stream will be listed in folder identified by the group name.

7-7 Storage Disk Maintenance
7-7 Storage Disk Maintenance
Your VGADVI Recorder Pro is equipped with one or more hard drives for storage of recordings. Occasionally,
maintenance is required for these disks. This section describes procedures for the following topics:
l Check disk storage space
l Schedule disk check
l Perform disk check
l Rebuild storage disks
l Verify RAID storage
Check disk storage space
The VGADVI Recorder Pro has a finite amount of storage This storage space holds a lot of recordings, but it can
get full. It’s a good idea to monitor your current disk usage.
If available storage is low, consider removing some unneeded recordings or setting up an automatic file
transfer with deletion after transfer. See File Maintenance and File and Recording Transfer.
Disk space can also be checked via the tablet interface. See Verify disk space via the tablet
interface.
To check disk storage space:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin or operator.
3. Check the Internal Storage section at the bottom of the menu column. The bar will be mostly green if
there is lots of space left, or mostly red if storage space is nearly full.
4. If available storage is low, take action to remove files as discussed in File Maintenance and File and
Recording Transfer.

7-7 Storage Disk Maintenance
Schedule disk check
A disk maintenance schedule is used to check the system storage drives for errors. Two values are supplied,
one to specify the number of system restarts that should occur before disk check, and the second to specify
the number of months before performing a disk check. The disk check happens based on whichever event
occurs first.
For example, the restart setting is set to 50 and the months setting is set to 6. If six months pass and less than
50 restarts happened, a disk check will occur on the next restart. However if you do 50 restarts in one month,
the disk check will happen after the fiftieth restart.
Disk check occurs during start up and can cause a lengthy delay in starting up the system.
To set the disk check schedule:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.
2. Login as admin.
3. Select the Disk Check link in the Configuration menu; the disk maintenance page opens.
4. Set the number of restarts to occur before the next check. Set to 0 if you don’t want to force a disk
check after a specific number of restarts.
5. Set the number of months to pass before the next check. Set to 0 if you don’t want to force a disk
check after a specific number of months.
6. Click Save.
Perform disk check
A disk maintenance schedule is used to periodically check the system storage drives for errors. If you prefer,
you can run the disk check manually at a time that is convenient for you.
Running the disk check manually resets the timers for the scheduled disk check (i.e. next check won’t happen
automatically until either the number of restarts or months passes).
If the system is recording when you start a disk check, it will stop recording and resume after the
check is complete. Frames presented during the disk check are not captured and are not part of
any recording.
To start a manual disk check:
1. Connect to the admin interface using your preferred connection mechanism. See Connect to the Admin
Interface.

5. Click Apply.
Control the VGADVI Recorder Pro with RS-232
You can use the null-modem cable and your control terminal software to issue commands to the VGADVI
Recorder Pro such as when to start or stop recording, or to retrieve or set the value for various settings.
Note: A line feed (ASCII code 10) is needed at the end of each command.
Some commands require a channel or recorder name as an argument. In those commands, the channel or
recorder name is separated from the command name by a period, as shown in the table. The channel name
value can be either the name or the index of the recorder or channel. Use of the index is recommended. A
channel’s index is found on the Channel Status page. In the screen capture below, the channel index is 2.
For commands requiring a recorder index, determine your recorder's index by combinging the recorder's
number with the prefix m. The recorder's number is found in the URL of the Recorder page. In the example
below, the recorder's number is 1. To access this recorder via RS232 commands, use the index m1.

7-9 Control with HTTP Commands
The VGADVI Recorder Pro has an HTTP API interface for configuration and control by a third party application
or with a script that sends commands to the system as a series of URLs. This section covers the following topics:
l HTTP Command Syntax
l HTTP Command Examples
HTTP Command Syntax
Control of the VGADVI Recorder Pro by HTTP is done by sending commands to one of two URLs and specifying
the target configuration item. Syntax for the get and set commands follows.
To Get configuration settings:
http://<address>/admin/channel<N>/get_params.cgi?key
To Set configuration settings:
http://<address>/admin/channel<N>/set_params.cgi?key=value
Where <address> is the IP address of the system, channel<N> is the channel number (i.e. channel2 for channel
number two), key is the key for the configuration item being checked or changed (see the list in
Configuration Keys for Third Party APIs ), and value is the value to set for the configuration item.
Multiple Requests at Once
You can include multiple key/value pairs in a single command by separating the statements with &.
For example, the key for product name is product_name and the key for firmware version is firmware_version.
To send a request for both the product name and the firmware version, use the following command:
http://<address>/admin/channel1/get_params.cgi?product_name&firmware_version
Or, to set the stream type (streamtype) to ASF and the bitrate (vbitrate) to 256,000:
http://<address>/admin/channel1/set_params.cgi?streamtype=2&vbitrate=256K

Using HTTP or RS-232, you can send commands to the system to query or configure the system. For the RS-232
and HTTP syntax see Control with RS-232 / Serial Port and Control with HTTP Commands.
When setting keys to values with spaces use the following syntax.
For RS-232:
Enclose in quotes: SET.2.framesize="640 x 480"
For HTTP:
Encode each space as %20: set_params.cgi?framesize=640%20x%20480

PART 7: Releases and Features
This section outlines the features introduced with each product release.
Release 3.11 Features
Recording Features
Multiple multi-track, multi-channel recorders
Save time in post-processing by specifying exactly which channels are included in a recording or choose to create an allin-one recorder to include all channels in a single multi-track file. Include the same channel in multiple recordings
wherever needed. Record all-in-one videos simultaneously with other needed recordings.
See Recorders.
Multiple audio sources
The VGADVI Recorder Pro now supports one audio input per DVI input in addition to the system's main line-in or
microphone. No need to pre-mix audio before routing it to the device for recording.
To support this change, the Audio menu tab has been removed and audio sources are now listed under the Sources
section. Audio inputs are named according to the capture card on which they reside. I.e. the audio input next to the
DVI input D2P83659.vga is called D2P83659_analog. Audio inputs from the server's main board have no product serial
number and are prefixed by audio.
Audio source mixing
Recorders and channels can contain multiple audio sources, resulting in any number of configurations of single source
or combined audio output. Incoming audio signals are mixed in software and levels are reduced proportionally to avoid
audio clipping.
The new mobile interface displays an overall audio input meter.
Precision time protocol (PTP) synchronization
Ensuring multiple sources are synchronized and time-stamped precisely is easier than ever. with support for PTP time
synchronization.
See Configure Date and Time.
Custom recording file names
Starting with release 3.11.0, you can customize the prefix used for recorded files. Use this to identify files being autouploaded from various rooms at a conference, or to keep track of which source is being recorded.
See Configure the type and length of recording files
Streaming Features
AAC audio codec
AAC is now supported for audio encoding. The system uses simplest and most commonly used AAC audio codec
profile: Low Complexity (LC). Mono audio only.
MPEG-TS streaming for IPTV
VGADVI Recorder Pro now supports MPEG-TS streaming over RTP/UPD and UDP for easy integration with IPTVs. Simply
provide the IPTV's or IPTV gateway's IP address in the channel's publishing configuration menu to enable transmission
of the MPEG-TS stream.
See Choose a codec to maximize your stream quality.
Universal plug and play (UPnP) support for streaming media players
Your system can now be discovered and streamed through software and hardware media players, set-top-boxes and
Smart TVs with ease. UPnP uses MPEG-TS over HTTP with the H.264 codec and MP3 or AAC audio encoding.
See Stream content using UPnP.
Layout and Branding Improvements
Visual stream feedback and simplified picture-in-picture layout
Video source previews are now available for each input. The preview function takes a single frame from the source every
three seconds and is visible from the Frame Grabber configuration pages.
If a given input has no signal a No Signal message is displayed. Previews are also visible via the new tablet interface. See
Configure a video source and Mobile / Tablet Operator Interface for details.
Creating multi-source layouts has never been easier! The new layout configuration screen shows you a live preview of
your configuration. Each added source can be clicked and dragged to a new location.
See Merge multiple videos into a single channel.
Stream branding and custom no signal image
You can customize output streams by adding your company logo or other overlay image to the encoded stream and by
providing a custom image to display prior to broadcast or other times when a source has no signal. Images in JPEG and
PNG format are accepted. Image transparency is not currently supported.
Preservation of source aspect ratio
A new feature, enabled by default, makes sure that the aspect ratio of input signals is preserved when encoded and
streamed. If an input video signal doesn't match the encoding ratio, a matte is applied and bars are visible at the sides
or top and bottom of the encoded stream. The color of the matte is customizable.
Customizable stream background color (matte)
You can select the matte color displayed when a layout results in pillarbox or letterbox effect due to input aspect ratio
preservation or when a multi-view layout has areas with no video.
Personalized stream metadata
Each channel has its own content metadata that you can configure to ensure proper attribution, content description
and copyright information is sent with your audio/video stream.
Mobile and Tablet Features
Introducing the mobile / tablet operator interface
Use your mobile device or tablet for confidence monitoring of channels, streams and audio levels. You can now start
and stop recordings from an interface designed for a touch-screen device. Point your smartphone or tablet to
http://<system IP address>/admin/m.
See Mobile / Tablet Operator Interface.
Discovery of Epiphan devices
Use the new Epiphan Connect application on Android and iOS as an alternative to the desktop based discovery utility.
The application has built-in support for opening the tablet operator interface and can be configured to automatically
open the tablet interface if connected to the VGADVI Recorder Pro by USB.
Mobile tethering
Release 3.11.0 introduces the option to use mobile tethering for recording control, confidence monitoring and mobile
network file transfers. Configure mobile data tethering and turn on automatic file uploads to automatically transfer
files to a remote site using the public mobile network. Alternatively, choose to tether for confidence monitoring and
recording control only.
Configure the VGADVI Recorder Pro to use no mobile data, to use Ethernet normally and switch to mobile data if the
Ethernet becomes unavailable, or to mobile data as the preferred transmission method.
Other Improvements:
l Based on the video encoder type, source resolution and stream frame size, the device now automatically
calculates a suggested bitrate that provides the best performance and quality trade off. Examples for H.264:
l 640×480, 15 fps, - 1.4 Mbps
l 1280×720, 20 fps - 2.6Mbps
l 1920×1080, 30 fps - 6.5 Mbps
l When using auto-file upload, you can choose to exclude specific channels from upload. This is useful if you
have one channel used for lower-quality streaming and another for higher-quality recording. Save space on your
network server by not uploading the lower-quality recordings automatically.
l You can now select what happens when you insert a USB drive: nothing; a one-time copy or transfer to the
drive; a manual copy or transfer to the drive; or automatic continuous copy or transfer of recorded files to the
drive.
l As of 3.11.0, you can configure the system to automatically upload recorded files to an attached USB drive.
Choose to either have it work the same way as uploading via FTP, CIFS, or RSYNC; or as a one-time download of
all the recordings on the system. Auto-file upload to USB drives supports storing recordings from each channel
in its own subfolder. See Upload to an External USB Drive
l Each audio and video input now indicates which channel(s) are using it, or if the input is not used. This can help
you determine if you have any inputs that are not being streamed or to assess which channels would be
affected by downtime for a given input.
l The HTTP Live Streaming (HLS) link is now displayed on the Channel Status page. HLS allows access to live
streams over the standard HTTP port 80, making able to traverse firewalls and proxies that are able access the
internet for other HTTP traffic.
l MPEG-TS format recording. This robust encoding mechanism has no index or trailer structures making it the
most fault tolerant format supported by the VGADVI Recorder Pro. MPEG-TS files are ready for streaming over
HTTP, RTP and UDP.
l Enjoy the new live stream resume feature to ensure a digital media player automatically gets the stream
when it becomes available after the VGADVI Recorder Pro restarts. Simply choose a stream and the UPnPenabled media player to control. See Stream content using UPnP.
l Direct your digital media player to play a recorded MPEG-TS files from the systeme. Browse to the Files
Archive and press the play button to choose from accessible uPnP media players.SeeStream content using UPnP
l Fast encoding has been removed and replaced with video encoding presets. New values are Default, High
Quality, and High Speed.
l H.263 (an older Flash implementation) is replaced with MPEG-4. As of Flash Player 9, update 3 (in December
2007), Flash supports H.264 encoding. If H.264 does not suit your needs, you can still support older players with
the MPEG-4 codec. The exact codec supported is Microsoft MPEG-4 version 2.
