Hi there, I have some issues with playing back HD (720p) material with mplayer and using the GL video output backend.
Usually my system is fast enough to playback 720p if the material is not subtitled. In case ASS style subtitles are used, using the standard Xv output is not fast enough. Therefore I tried to improve the display performance by switching to the GL output backend, which should perform better. It does perform better but I now loose AV-sync. >From the mplayer manpage: swapinterval=<n> Minimum interval between two buffer swaps, counted in displayed frames (default: 1). 1 is equivalent to enabling VSYNC, 0 to disabling VSYNC. Values below 0 will leave it at the system default. This limits the framerate to (horizontal refresh rate / n). Requires GLX_SGI_swap_control support to work. With some (most/all?) implementations this only works in fullscreen mode. I'm using these components: gentoo-sources-2.6.30 libdrm git master mesa git master xf86-video-intel-2.9.1 Could this be a DRI2 related problem? IIRC the vsync stuff for DRI2 is currently in flux and probably not working correctly. I should mention that the AV-sync is lost both with windowed and fullscreen mode. So it doesn't really matter if I start the player with -fs or not. Also the CPU utilization is clearly lower than the one when using Xv and it's also clearly lower than 100% (somewhere around 70%). So the system should be fast enough to do the task, but somehow GLX_SGI_swap_control isn't working like it should. Can somebody comment on this issue?
