          Priority: medium
            Bug ID: 63090
          Assignee: dri-devel@lists.freedesktop.org
           Summary: mesa 9.2git: qvdpautest fails to work with UVD but
                    also fails with shader decoding
          Severity: normal
    Classification: Unclassified
                OS: All
          Reporter: arekm@maven.pl
          Hardware: Other
            Status: NEW
           Version: git
         Component: Drivers/Gallium/r600
           Product: Mesa

Tried to test vdpau using
https://github.com/robertmassaioli/qvdpautest

but it failed with:
qvdpautest 0.5.2
AMD E-350 Processor
Unknown GPU

VDPAU API version : 1
VDPAU implementation : G3DVL VDPAU Driver Shared Library version 1.0

FATAL: get_bits failed : No backend implementation could be loaded.!!

and very bad framerate (MPEG DECODING (1920x1080): 53 frames/s)

"No backend implementation could be loaded" happened with shaders decoding and
also with UVD decoding (while mplayer -vo vdpau worked fine on both cases)

"No backend implementation could be loaded" is mesa
VDP_STATUS_NO_IMPLEMENTATION



Test environment:
- kernel from drm-fixes + radeon UVD patches
(http://lists.freedesktop.org/archives/dri-devel/2013-April/036766.html +
http://paste.debian.net/247063/)

- mesa 9.2 from master as of 302df7cc85b0e2ce47c40048f30bd116b0d692fc + patches
http://comments.gmane.org/gmane.comp.video.mesa3d.devel/55622 and
http://lists.freedesktop.org/archives/mesa-dev/2013-April/037089.html

- E350 AMD APU with [AMD] nee ATI Wrestler [Radeon HD 6310] GPU

- vdpauinfo with UVD working: http://pastebin.com/FjpLyMqr

--- Comment #1 from ryszardzonk@yahoo.com ---
I have same platform as Arkadiusz [E-350] and I can confirm his results of 53
frames/s. 

software used:
Kernel 3.9-rc6 + drm uvd patches
libdrm Git 08.04.2013
xorg-server 1.13.3
Mesa Git 08.04.2013 + uvd patch

On the other hand mplayer -vo vdpau was not enough to get smooth playback of
H264 content. I had to specify "mplayer -vo vdpau -vc ffh264vdpau" with perfect
results. Using standard combination of "mplayer -vo vdpau -vc
ffmpeg12vdpau,ffvc1vdpau,ffh264vdpau,ffodivxvdpau" on the H264 content made
mplayer use ffmpeg12vdpau which resulted in jerky playback. 
Using XBMC from FernetMenta tree https://github.com/FernetMenta/xbmc which has
number of vdpau playback fixes resulted in jerky playback for high bitrate
content at 1920@1080.

As of VC1 content any player I used created either dark screen with green
artifacts at playback

Please let me know if You need any logs (dmesg/Xorg/lspci) or configs
(kernel/Xorg) or any other for that matter

--- Comment #2 from Christian König <deathsimple@vodafone.de> ---
That's a bug in qvdpautest. It tries to get the surface data in YUYV format,
which is simply not supported by the hardware.

We could implement a software fallback, but mesuring that would be pretty much
nonsense.
