Heavy artifacts during hw accelerated playback of wmv files

Heavy artifacts during hw accelerated playback of wmv files

[Jan Burgmeier]

Hi,

with versions newer than libdrm-2.4.66 I have heavy artifacts during hw
accelerated playback of wmv files vaapi/vdpau tested with gstreamer-
0.10 and ffmpeg based mpv.

Bisect result:
db138b9ba12a0de5d6140832c0679c2418e3e7e0 is the first bad commit
commit db138b9ba12a0de5d6140832c0679c2418e3e7e0
Author: Michel Dänzer <michel.daenzer@amd.com>
Date:   Thu Jan 21 18:08:49 2016 +0900

    radeon: Pass radeon_bo_open flags to the DRM_RADEON_GEM_CREATE 	
ioctl
    
    Not doing so makes it impossible for radeon_bo_open callers to set
any
    RADEON_GEM_* flags for the newly created BO.

If I revert this commit on the current master branch the artefacts are
gone.

System environment:
-- chipset: AMD GX-217GA SOC with Radeon(tm) HD Graphics
-- system architecture: 32-bit
-- xserver: 1.19.1
-- mesa: 13.0.3, 13.0.6, 17.0.2
-- libdrm: 2.4.74
-- kernel: 4.4.11
-- Linux distribution: eLux
-- Machine or mobo model: HP t620 dual core thin client

Without this change, the flags passed to radeon_bo_open are ignored. The
question is which flag passed from where is causing the trouble.

Hi Jan,

very interesting. Sounds like we somehow mess up the buffer placement so 
that it won't work any more with UVD.

But this only happens with WMV files? Not with H264 or anything else?

Anyway please open up a bug report on https://bugs.freedesktop.org/.

Thanks,
Christian.

Hi,

the error only occurs with wmv, h264 works.

I created a bug report:
https://bugs.freedesktop.org/show_bug.cgi?id=100510

Regards,
Jan
