Linux Video Capture Workstation Software
6
Linux Video Capture Workstation Software
Epiphan provides the Epiphan USB device driver and the Epiphan capture API for
Linux. Epiphan does not provide a video capture application for Linux. However, the
USB device driver is compatible with Video4Linux so you can use Video4Linux
compatible applications to receive and process captured images. You can also use
the Epiphan Linux SDK to write your own custom video capture application that
receives captured images from the Epiphan capture API. The following software
components operate on a video capture workstation running Linux:

The Epiphan USB device driver

Video4Linux

The Epiphan capture API

V4L custom video capture applications
6.1 The Epiphan USB Device Driver
The Linux Epiphan USB device driver receives images from an Epiphan DVI2PCIe
and delivers the images to the Epiphan capture API and to Video4Linux. Before
delivering the images the Epiphan USB device driver also performs image adjustment
to improve the quality of the image. Image adjustments include setting the sampling
phase, PLL adjustments, and horizontal shift. The USB device driver can also change
the color depth of the captured image before sending the image to the video API. For
example, if the DVI2PCIeis capturing the frames at a color depth that is different than
that required by the video capture application, the USB device driver converts the
images to the required color depth.
The Epiphan USB device driver may not be available for your version of Linux.
Epiphan does not provide source code for the Epiphan USB device driver. But you can
contact Epiphan if you need an Epiphan USB device driver compiled for a specific
18
DVI2PCIe User Guide
Linux Video Capture Workstation Software
Linux kernel version or kernel setting. Using the Epiphan software development kit
(SDK) you can also create custom USB device drivers that incorporate the functions
that you need.
6.2 Video4Linux
Video4Linux (V4L) is a Linux video capture API. The Epiphan USB device driver can
send captured images directly to Video4Linux. This means that any Video4Linuxcompatible application can receive captured images. You can use a Video4Linuxcompatible application to record a series of captured images as a video in the video
format supported by the Video4Linux application. You can also create your own
custom Video4Linux-compatible video capture application to record captured images
from Video4Linux.
6.3 The Epiphan Capture API
The Epiphan Capture API also receives captured images from the Epiphan USB
device driver. It is optimized for processing Epiphan DVI2PCIe captured images. The
Epiphan Capture API analyzes individual images, performs on-device cropping, and
handles video mode changes. It is an alternative to using Video4Linux to capture
images on Linux video capture workstations. You can use the Epiphan software
development kit (SDK) to create your own custom video capture application to record
captured images from the Epiphan Capture API.
6.4 V4L Custom Video Capture Applications
Epiphan does not provide a video capture application for Linux. However, you can use
Video4Linux-compatible applications to perform many video capture operations such
as recording images or video, copying, printing and saving images, or broadcasting
images across the Internet. You can also use the Epiphan Linux SDK to create your
own custom video capture application. The SDK along with some example

Append suffix…
When you start a video recording session you
are prompted to enter a file name. If the file
exceeds the AVI file size limit, the DVI2PCIe
user interface starts another file named with the
original file name appended with a sequential
numeric suffix. Use the append suffix options to
specify the format of this suffix.
Each suffix starts with a % sign and can include
the following characters:
02, 04, 06, or 08 indicates the number of digits
to use in numbering the suffix. You can specify
2, 4, 6, or 8 digits.
“d” means decimal numbers are used in the
suffix.
“X” means hexadecimal numbers are used in
the suffix.
The suffix %02d means the saved file names
would end with two-digit decimal numbers, for
example: 01, 02, 03, ..., 10, 11 and so on. The
suffix %04X means the saved file names would
end with 4-digit hexadecimal numbers, for
example: 0001, 0002, 0003, ..., 000A, 000B
and so on.

10 Web Broadcasting
You can use the information in this chapter to share or broadcast the images captured
by your DVI2PCIe over the Internet. Note that web broadcasting is available only on
video capture workstations running Windows.
To broadcast captured images over the Internet, the video capture application sends
captured images to an Epiphan web broadcasting portal. Each web broadcast session
is labelled with the serial number of the DVI2PCIe that is capturing the images. The
card’s serial number appears on the video capture application title bar.
Web broadcasting sends the currently captured image only. You cannot broadcast
saved recordings and the DVI2PCIe’s web broadcasting feature does not include
sound.
Note: The web broadcasting feature included with the Epiphan video capture
application is intended as a demonstration only and has a 10-hour time limit.
It is important to note that the images broadcasted over the Internet are not secure.
Potentially anyone can view the web broadcast if they know the correct URL. The web
broadcasting supported by the video capture application is a relatively limited feature.
Epiphan’s broadcasting products provide a richer web broadcasting feature set.
10.1 To set the display format for web broadcasting
1.
Open the DVI2PCIe capture tool application on a video capture workstation
running Windows.

Optionally limit the frame rate to reduce the number of images sent over the
Internet reducing the amount of bandwidth being used. Depending on your
requirements you may not have to change any other display settings. Refer
to section, Configuring Display Options for all available display settings.
6.
Select OK to save your changes.
10.2 Starting a web broadcasting session
No special setup is required for web broadcasting except that the video capture
workstation must be able to connect to the Internet. The video capture workstation can
be connected directly to the Internet or to a LAN that is connected to the Internet.
Before broadcasting captured images over the Internet you need to set the display
format to 24 bits per pixel. Please refer to the previous section To set the display
format for web broadcasting.
To start a web broadcast:
1.
Connect the Epiphan Frame Grabber to the video source that you want to
broadcast and to the video capture workstation.
2.
Start the Epiphan capture tool application.
3.
Select Web Broadcasting from the Tools menu or from the toolbar select
.

10.3 Viewing a web broadcasting session
You can view a web broadcasting session from a web browser running under
Windows 2000, XP, Vista and 7 versions. The following browsers are now supported:
- Internet Explorer
- Firefox
- Opera
- Chrome
- Safari.
Mobile browsers are also supported if the mobile device is compatible with Java SE.
The working station and web browser should be running the most recent version of the
Java plug-in. You can download the plug-in’s latest version from http://www.java.com.
To view a web broadcast:
1.
Open a web browser and browse to the required URL, for example:
http://www.vga2web.com/D2P00000. This URL is supplied by the vga2web
application as shown on the Figure 20 Start Web Broadcasting Dialog and
can be advertised to potential viewers of the broadcast.
A second web browser window appears displaying the message Applet is
loading. Please wait… The broadcasted image should appear within 10 to 20
seconds.
53
DVI2PCIe User Guide
Web Broadcasting
The first web browser window in which the web broadcast URL address was
entered, displays a message indicating that the web presentation has been
opened in a new window. You can also use the first window to refresh the
broadcast or re-open the broadcast window if it is accidentally closed.
10.4 Changing web broadcasting compression and
performance
Normally you should not need to change the default web broadcasting compression
settings. The default settings reduce the amount of Internet bandwidth used for web
broadcasting by applying a combination of lossless and lossy compression to the
images being broadcasted.
To change the web broadcasting compression, from the Tools menu of the DVI2PCIe
capture tool select Options and then select Sharing. Select Override default
compression settings and adjust the Lossless and Lossy settings.
10.5 Troubleshooting web broadcasting performance
Here are three typical reasons for adjusting web broadcasting compression:

If you have a slow Internet connection or if viewers of the web broadcasts
notice delays you can increase lossless or lossy compression to reduce
Internet bandwidth usage.

If viewers of the web broadcast notice poor image quality you can reduce the
amount of lossy compression.

If the video capture workstation CPU usage is too high during web
broadcasts or if viewers of the web broadcasts notice delays and you have
determined that the delays are not caused by low Internet bandwidth. The
delays could be caused by high CPU usage on the video capture workstation
resulting in the video capture workstation not being able to process all image
54
DVI2PCIe User Guide
Web Broadcasting
data. Lossless compression increases CPU usage, so you can reduce CPU
usage during web broadcasting by reducing lossless compression.
Note: You cannot change web broadcasting compression during a web broadcast.
You must stop the broadcast, adjust the settings and then start the broadcast again.
Changes made to default web broadcast compression settings are only visible to
viewers of the web broadcast. Changing these settings does not change how the
video capture application displays, records, or prints captured images.

11.1 EDID
Extended display identification data (EDID) is data provided by a video display device
(usually a monitor) to describe its capabilities to a video source. The video source
uses the EDID to determine the capabilities of the monitor and, therefore, to
determine the resolution, color depth and other settings that the monitor will accept.
11.1.1
About EDID
EDID is defined by a standard published by the Video Electronics Standards
Association (VESA). The EDID includes manufacturer name, product type, phosphor
or filter type, timings supported by the display device, display size, luminance data and
(for digital displays only) pixel mapping data. EDID is crucial for DVI sources but
mostly ignored by VGA sources.
When you connect a DVI2PCIe to a video source, the video source sees the
DVI2PCIe as a monitor. Just like a monitor, the DVI2PCIe contains EDID that is used
by the video source to determine the video signal to send to the DVI2PCIe.
Usually you would operate a DVI2PCIeusing the factory installed default EDID.
However, in some cases when you connect a DVI2PCIe to a video source, the video
source may operate using video settings that you do not want it to operate at. For
instance, you can control the video source output settings by uploading a custom
EDID file to the DVI2PCIe. The EDID information in the file restricts the video signal
that can be accepted by the DVI2PCIe. For example, you can upload a custom EDID
file to your DVI2PCIethat reports that the DVI2PCIeonly operates at 1040x768. When
the video source reads the EDID from the DVI2PCIe, the video source will reset to
operate at 1024x768 as set in the EDID.

You can obtain custom EDID files from Epiphan Support. You can also download
custom EDID files for DVI2PCIe frame grabber from the frame grabber product page
of the Epiphan web site. This page contains custom EDIDs for single video resolutions
(for example, 640x480 only, 800x600 only, and 1024x768 only) for each DVI2PCIe.
This page also contains default EDIDs for each DVI2PCIe. You can use the custom
EDIDs to restrict the video resolution of the video source connected to the DVI2PCIe.
You can use the default EDIDs to return your DVI2PCIe to normal operation.
11.1.2
Changing the EDID on your Frame Grabber
Use the following steps to upload a new EDID to your DVI2PCIe. The uploaded EDID
is permanently installed in the DVI2PCIe and the DVI2PCIe will always share this
EDID with the video source.
1.
Download an EDID file from the Epiphan web site or obtain an EDID file from
Epiphan Support.
2.
Disconnect the DVI cable from the DVI2PCIe. Keep the DVI2PCIe connected to
the video capture workstation USB port.
3.
From the video capture application Tools menu, select Upload EDID and select
the EDID file.
4.
Wait for the EDID update to complete. This can take several minutes.
5.
Reconnect the DVI cable to the DVI2PCIe.
6.
Set the required resolution on the video source. You may need to disable/reenable or reset the DVI port.
11.1.3
An EDID example
In this example, a user was viewing the video output from a system using a flat panel
monitor. The monitor displayed video images at a screen resolution of 640x480. When
the user replaced the flat panel monitor with a DVI2PCIe, the system changed to
produce video images at a screen resolution of 720x400.
57
DVI2PCIe User Guide
Advanced Topics
It turned out that the video source preferred to output 720x400, but because the
original monitor did not support 720x400, the video source was forced to operate at
640x480. The DVI2PCIe supported 720x400 so the system changed to this
resolution when the DVI2PCIe was connected to it.
The user wanted to return the video source to operating at 640x480 but could not
manually adjust the screen resolution. To solve the problem, Epiphan created a
custom EDID for the DVI2PCIethat excluded support for 720x400. When the user
uploaded the custom EDID to the DVI2PCIe, the video source returned to operating at
640x480.
11.2 Windows command line options
You can use the following command line options to control how the Windows video
capture application starts up. You can add as many command line options as you
want in any order. All command line options must start with two dashes. Separate
command line options with spaces.
--borderless
Start the video capture application in image only
mode. You can press Esc to exit from image only
mode.
--sn <sn>
To specify which Frame Grabber to use if more than
one Frame Grabber is connected to the PC. Similar
to the Capture menu Select Device command.
<sn> is the serial number of the Frame Grabber.
--hs <#>
Set the horizontal shift*. The range is -100 to 100.
--vs <#>
Set the vertical shift*. The range is -80 to 80.
--phase <#>
Set the sampling Phase*. The range is 0 to 31.
--pll <#>

11.2.1
Creating a Windows Shortcut that Uses Command Line Options
You can use video capture application command line options by creating a Windows
shortcut to the video capture application executable file and editing the shortcut to add
command line options. In the following procedure, the video capture application
executable file v2ugui2.exe has been installed in the folder C:\Program
Files\DVI2USB30:
1.
Open Windows Explorer and navigate the following path:
C:\Program Files\DVI2USB30
2.
Right click on the file v2ugui2.exe and select Create Shortcut. Windows creates a
shortcut file that, depending on your Windows settings, may be named “Shortcut
to v2ugui2.exe.lnk”. The “.lnk” may not appear if Windows does not display file
extensions. You can change the name of this file and copy it to another location if
required. Don’t change the file extension.
3.
Right click on the shortcut file and select Properties.
4.
Edit the Target field and add command line options after the closing quote. For
example, to add the --topmost command line option:
"C:\Program Files\DVI2USB30\v2ugui2.exe" –topmost
For example, to add --topmost and --borderless, set the horizontal shift to -67,
and the vertical shift to 10:
"C:\Program Files\DVI2USB30\v2ugui2.exe" –topmost --borderless --hs -67 --vs
10
5.
Select OK to save your changes to the shortcut.
6.
Double-click on the shortcut to start the video capture application with the
command line options.
