[Bug 87054] VDPAU decoding mostly fails with Assertion `0' failed. (r600g, Radeon HD 8570D)

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_stu...
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.

--- Comment #2 from Kertesz Laszlo laszlo.kertesz@gmail.com --- 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.
