I was complaining about the fact that the definitions for the V4l2 pixel formats have very little to in common with the way that the xvideo extensions defines them. Since it is at least somewhat logical to display captured video using xvideo, it would be nice if there was a bit of linking. And this may be pie in the sky, because I don't know about how dma transfers work and the such, but it would be super sweet if you could get shared memory from X windows to use with the xvideo extension, and then get the capture card to capture straight to those buffers. I realize that it would only cut out a little bit (one memcpy per display), but it would still be sweet. Would that be possible? Chris
