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
