When using xbmc with vdpau acceleration enabled, I get a green screen (audio works), and this appears in the kernel log : nouveau E[ PFIFO][0000:03:00.0] DMA_PUSHER - ch 6 [xbmc.bin[22420]] get 0x00200f06c8 put 0x00200f0770 ib_get 0x000000db ib_put 0x000000dc state 0x80000000 (err: INVALID_CMD) push 0x00400040 Sometimes it makes xbmc crash completely. This is on an nv50 (Chipset: MCP79/MCP7A (NVAC) ) : VGA compatible controller: NVIDIA Corporation ION VGA (rev b1) Mesa 10.1 libdrm 2.4.52 It works all right using mplayer. Just a wild guess : something to do with GL_NV_vdpau_interop? If you need any more information, I'd be happy to provide it.

Yep, it has to do with vdpau interop. I think that the DMA_PUSHER error is unrelated, but not sure. There were some patches to make it work better on nouveau, not sure if they made it to 10.1 -- try 10.2? mplayer should work fine.

Does it work fine until it crashes, or does it crash too fast for you to tell? Those errors are fairly non-sensical, at least the first, which leads me to believe that it's a fallout from sharing the screen among multiple contexts. There are lots of bugs in that area, it's something I plan on looking at over the weekend.
(In reply to comment #4) > Does it work fine until it crashes, or does it crash too fast for you to > tell? Yes, it seems to work fine. I got to watch a record 20 seconds of video, and it appeared to work fine. Mind you, it wasn't a FullHD video. I'm open to patch testing ;)
Still happens with mesa 10.3 and xbmc 13.2. Any news?
