Nouveau - Mar 2014 - [Bug 76173] New: xbmc green screen with vdpau enabled

https://bugs.freedesktop.org/show_bug.cgi?id=76173

          Priority: medium
            Bug ID: 76173
          Assignee: nouveau at lists.freedesktop.org
           Summary: xbmc green screen with vdpau enabled
          Severity: normal
    Classification: Unclassified
                OS: Linux (All)
          Reporter: serafean at gmail.com
          Hardware: x86-64 (AMD64)
            Status: NEW
           Version: 10.1
         Component: Drivers/DRI/nouveau
           Product: Mesa

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.

xbmc stdout on first crash

I just installed mesa from git [Mesa 10.2.0-devel (git-f9901f1)] and while the
green display is gone, yet xbmc still crashes.

relevant dmesg output :

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.

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?
