Re: Stubborn VBLANK with vdpau (fullscreen?)
VDPAU's presentation queue will display each frame for at least one vblank. It's up to the application to query the presentation queue, find out when the frame was presented, and compare that to the requested timestamp. If it detects too much drift, it should drop frames to compensate. It sounds like that algorithm is not working in mplayer. As far as I know, there is no way to disable sync-to-vblank in VDPAU.
