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 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
7.1 The Epiphan USB Device Driver
The Linux Epiphan USB device driver receives images from an Epiphan DVI2USB 3.0
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 DVI2USB 3.0 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.
