[VDPAU] Can only get MPEG1/2 decoding to work

OpenGL renderer string: Gallium 0.4 on AMD RV770

The is no UVD support on RV770 at this time.

ah ok thx, that explains everything

$ mplayer test.mp4
[...]
Starting playback...
[VD_FFMPEG] Trying pixfmt=0.
Movie-Aspect is 1.78:1 - prescaling to correct movie aspect.
VO: [vdpau] 1280x720 => 1280x720 H.264 VDPAU acceleration 
[VD_FFMPEG] XVMC-accelerated MPEG-2.
A:  18.1 V:  18.1 A-V:  0.000 ct: -0.001   0/  0  3%  1%  1.4% 3 0

I find this a bit confusing: H264/MPEG2, VDPAU/XVMC - which is it then?

I think it's using VDPAU... But I'm not sure, don't know too much about mplayer's outputs, that is confusing...

mpv's output (thanks for the suggestion!) seems to be far more sane in that regard:

$ mpv test.mp4
Playing: test.mp4

VO: [vdpau] 1280x720 => 1280x720 vdpau 
[vo/vdpau] Compositing window manager detected. Assuming timing info is inaccurate.

Anyway, thanks for all the help. With this and hardware accelerated flash working at last I couldn't be happier.

Thanks again for everything!

Yes, mpv's outputs are nice and clean, and to use hardware video decoding with vdpau on mpv all you need is --vo=vdpau and --hwdec=vdpau
