Why not to use SDL? This would give you much better cross-platform
compatability.

SDL does not (yet?) support the yuv-things that the xvideoextension support.
That would be one reason…

I have written a small testprogram that uses the xvideo extension. It
tests the available video adapters, outputs its informations and
displays a window with a small color effect. It uses hardware yuv->rgb
colorspace conversation and scaling/filtering if available.
(the url is: “http://www.cs.uni-potsdam.de/~wertmann/xv/”)
There are also some docs about the xvideo extension I found in the xf4
distribution.

You can also look into xawtv version 3.x. It uses the xv extension to
display image data, to do the colorspace conversation and to scale the
image data.

I hope this helps a bit.
bye,
