Epiphan Frame Grabber

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

that you need.

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.

The Epiphan capture API

The Epiphan capture API also receives captured images from the

Epiphan USB device driver. The Epiphan capture API is

optimized for processing Epiphan Frame Grabber captured

images. The Epiphan capture API analyzes individual images,

performs on-device cropping, handles video mode changes and

also supports KVM functions if you are using a KVM2USB Frame

Grabber.
The Epiphan capture API 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.
