X-Video is an X-server extension that provides functions for
hardware colorspace conversion and scaling, also it can provide
mechanisms to get images from video devices into a window. Most
of these are hardware-specific features and the X-Video extension's
presence depends on drivers. Running the "xvinfo" program that
comes with XFree86 will report the X-Video capabilities of the
X-Server.
I believe xawtv can operate without it, but in a hackish sort of way.
