Using a DirectShow application to

record video files

This section describes how to use the VirtualDub freeware

application to capture images from an Epiphan Frame Grabber

and record the captured images as *.avi video files. You can

download and install VirtualDub from

http://www.virtualdub.org/

.

This is not a detailed description of how to use VirtualDub. This

section provides a basic example of how to use a DirectShow-

compatible application to capture images using an Epiphan

Frame Grabber. Even though these instructions are specific to

Virtual Dub, you can apply them to any third-party video capture

application that can get images from DirectShow. For more

information about DirectShow, see

“DirectShow” on page 37

.

Epiphan Frame Grabbers communicate with VirtualDub using

the DirectShow API. Any DirectShow-compatible image capture

application installed on a video capture workstation that is

connected to an Epiphan Frame Grabber can also receive

captured images from the Frame Grabber.
The key to capturing images from an Epiphan Frame Grabber

using a DirectShow-compatible capture application is to find the

Frame Grabber from the capture application. To be able to find

the Frame Grabber, you must install the Epiphan USB device

driver on the video capture workstation and connect the Frame

Grabber to the video capture workstation.
