7 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 tool 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

7.1 The Epiphan USB Device Driver

The Linux Epiphan USB device driver receives images from an Epiphan DVI2PCIe Duo 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 DVI2PCIe Duo is 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 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 you need.

7.2 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 Video4Linux-compatible application can receive captured images. You can use a Video4Linux-compatible 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.

7.3 The Epiphan Capture API

The Epiphan Capture API receives captured images from the Epiphan USB device driver. It is optimized for processing Epiphan DVI2PCIe Duo 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.

7.4 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 applications is available from the downloads page of the Epiphan Web Site. To download the latest version, browse to http://www.epiphan.com/products and locate the downloads page for your product.

supported by the Epiphan Capture Tool is a relatively limited feature. Epiphan's streaming products provide a richer web streaming feature set.

13.1 To set the display format for web streaming

1. Open the capture tool on a video capture workstation running Windows.
2. From the Tools menu select Options.
3. Select the Display tab.
4. Set Display Format to RGB 24 bits per pixel.

A second web browser window appears displaying the message Applet is loading. Please wait... The streamed image should appear within 10 to 20 seconds.

The first web browser window in which the web stream URL address was entered, displays a message indicating that the web presentation has been opened in a new window. Use the first window to refresh the stream or re-open the stream window if it is accidentally closed.

13.4 Changing web streaming compression and performance

Normally you should not need to change the default web streaming compression settings. The default settings reduce the amount of Internet bandwidth used for web streaming by applying a combination of lossless and lossy compression to the images being broadcasted.

To change the web streaming compression, from the Tools menu of the DVI2PCIe

- If the video capture workstation CPU usage is too high during web streaming or if viewers of the web stream 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 data. Lossless compression increases CPU usage, so you can reduce CPU usage during web streaming by reducing lossless compression.

Note: You cannot change web streaming compression during a web broadcast. You must stop the stream, adjust the settings and then start the stream again.

Changes made to default web stream compression settings are only visible to viewers of the web stream. Changing these settings does not change how the video capture application displays, records, or prints captured images.

Advanced Topics

When you connect a DVI2PCIe Duo to a video source, the video source sees the DVI2PCIe Duo as a monitor. Just like a monitor, the DVI2PCIe Duo contains EDID that is used by the video source to determine the video signal to send to the DVI2PCIe Duo.

Usually you would operate a DVI2PCIe Duo using the factory installed default EDID. However, in some cases when you connect a DVI2PCIe Duo to a video source, the video source may operate using video settings at which you do not want to operate. For instance, you can control the video source output settings by uploading a custom EDID file to the DVI2PCIe Duo. The EDID information in the file restricts the video signal that can be accepted by the DVI2PCIe Duo. For example, you can upload a custom EDID file to your DVI2PCIe Duo that limits the DVI2PCIe Duo to operate at 1040x768. When the video source reads the EDID from the DVI2PCIe Duo, 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 Duo frame grabber from the frame grabber product page of the Epiphan web site. This page contains custom EDIDs for single video

1. Disconnect any input cables from the DVI2PCIe Duo. Keep the DVI2PCIe Duo connected to the video capture workstation USB port.
2. From the video capture application Tools menu, select Upload EDID and select the EDID file.
3. Wait for the EDID update to complete. This can take several minutes.
4. Reconnect input cables to the DVI2PCIe Duo.
5. Set the required resolution on the video source. You may need to disable/re-enable or reset the DVI or SDI input port.

14.1.3 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 Duo, the system changed to produce video images at a screen resolution of 720x400.

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 Duo supported 720x400 so the system changed to this resolution when the DVI2PCIe Duo 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 DVI2PCIe Duo that excluded support for 720x400. When the user uploaded the custom EDID to the DVI2PCIe Duo, the video source returned to operating at 640x480.
