            Bug ID: 87054
           Summary: VDPAU decoding mostly fails with Assertion `0' failed.
                    (r600g, Radeon HD 8570D)
           Product: Mesa
           Version: git
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/r600
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: laszlo.kertesz@gmail.com

Building recent mesa git i found that most video players that use VDPAU 
hardware decoding fail with

vl/vl_stubs.c:45:vl_video_buffer_formats: Assertion `0' failed.
Trace/breakpoint trap

for example trying to play a 1080p h264 video that worked with hw 
decoding before:

$ mpv /media/bigdata/Videos/1080ptestvideo.mp4
Playing: /media/bigdata/Videos/1080ptestvideo.mp4
[stream] Video (+) --vid=1 (*) (h264)
[stream] Audio (+) --aid=1 --alang=und (*) (aac)
File tags:
 major_brand: mp42
 minor_version: 0
 compatible_brands: isommp42
 creation_time: 2012-09-10 21:27:25
Trying to use hardware decoding.
AO: [alsa] 44100Hz stereo 2ch float
vl/vl_stubs.c:45:vl_video_buffer_formats: Assertion `0' failed.
Trace/breakpoint trap


It happens to mpv and xbmc, but interestingly NOT to vlc (built with 
VDPAU support) when using (or attempting to use) hardware decoding. 
With hw decoding off all work.
Only player that can use VDPAU is vlc built from git.

The vl_stubs.c file is referenced in one commit,

http://cgit.freedesktop.org/mesa/mesa/commit/src/gallium/auxiliary/vl/vl_stubs.c?id=f093c1c8ec1bce50d9338533ce775b564358fbeb

auxiliary/vl: add galliumvl_stub.la

Tried to revert it and didnt work.

I use Debian Testing 64 bit with kernel, drm, mesa, llvm built from git.
Now i have  last commit a28ad9d4c0d4b95aee8c3b99e9aaa59add21ea9d in my current
build of mesa, kernel 3.18.0-rc7-00057-gebea76f.

Might be. But on my system mpv segfaults too with vdpau and mplayer shows no
video (the latter may be somewhat different issue).

Yea, I can get mpv to segfault also - when I initially tested I used 

... --hwdec=vdpau --vo=vdpau ...

which still works as it's "pure" vdapu, with current mpv ommiting the
--vo=vdpau makes it use opengl for vo and I guess the  nv_vdpau_interop that is
causing the problem.

Todays mplayer still works for me.

Well seems that you are right. I re tested with mpv and works.
I really dont know what caused the issue since i had in ~/mpv/config:

vo=vdpau
hwdec=auto
hwdec-codecs=h264,vc1,wmv3,mpeg2video,mpeg4

before and it crashed. Maybe for some reason it didnt take the vo option or
something. It still crashes if use vo=opengl but after changing it back to
vdpau it started working.
This and the fact that mplayer exhibits other issues (something related to
avcodec missing h264 decoding) leads me to think that this bug is indeed
duplicate of 86837.
