To fix this properly I need to get mplayer's frame playback locked to the frame VSYNC of the video card. (Or, perhaps, lock the video card to mplayer's frame playback?). I believe that with this done, a Linux box could give video playback indistinguishable from broadcast.
What are my options? Are there any facilities in Xv/X to sense display card vsync? Have I missed the obvious fix for this?
Allthough the api might be a bit proprietary, if you have a matrox card, you can use syncfb which consists of a kernel and a library that allows you to upload yuv data the gfx card and copy it into the overlay triggered by the VSYNC interrupt from the gfx card. It works with both X11 and fb.
