I can make vdpauinfo work with two patches, but I haven't looked at making
anything play yet!

one patch is for libvdpau and one patch for mesa.

Thanks airlied, it works for me.

However, on KWin, I have to minimize and then maximize again the video in order
to have the video rolling. Otherwise, I only see an empty/black window.

I've tried both patches. It seems like everything works pretty well. So
vdpainfo now shows the supported formats. The 1080p video plays without any
problem (I also use kwin, xrender in particular) in mplayer. Top showed
decrease in CPU usage while using VDPAU.
Dave, thank you for the fast fix.

Sounds like we can close the bug as soon as the proposed patches are upstream.

I applied Dave's patch to libvdpau:
http://cgit.freedesktop.org/~aplattner/libvdpau/commit/?id=22a2f15f3e5f36641f72211da9f786b6778d0481

I'll make an 0.7 release to pick up this and a file descriptor leak fix soon,
unless something else crops up before then.

@Martin Peres, I've done a little bit of investigation. 
 So if I don't use any desktop effects in kwin, the video on mplayer+VDPAU is
choppy and not visible sometimes (except fullscreen). Also in this case I
cannot exit fullscreen. Basically double click doesn't have any effect as well
as alt+tab. Or to be more precise it seems like a window is minimized but the
video is on top of desktop. 
 If I use desktop effects+Xrender everything works like a charm. 
 The desktop effects+OpenGL render behave exactly like you described in your
message. 
 By the way I use KDE 4.10.5 (OpenSUSE 12.3). Is it possible that this issue a
bug in kwin? Which options do you use in KDE?

@Hohahiu: I always use GL, so I guess we are seeing consistency here. This is
good. We should try with other compositors and see if it helps.

would these patches work for a "muxed" hybrid laptop as well ? 
Otherwise, what would be needed to have libvdpau automatically pick up the
right driver on muxed systems ?
