Example of the garbage with the video "Test_1440x576_WVC1_6Mbps.wmv"
Playing WVC1 encoded videos with VDPAU hardware acceleration in a Radeon
platform causes the playback to show a lot of garbage.
This happens occasionally: sometimes it works perfectly and sometimes it shows
the garbage.
It happens with videos encoded in either simple, main or advanced.
This thread in the mailing list talks about the same behaviour, but we couldn't
find a bug reported about this, and this happens to advanced profile too:
<a href="https://lists.freedesktop.org/archives/mesa-dev/2015-September/095144.html">https://lists.freedesktop.org/archives/mesa-dev/2015-September/095144.html</a>
Testing with the same videos in the thread:
<a href="http://samples.ffmpeg.org/V-codecs/WVC1/Test_1440x576_WVC1_6Mbps.wmv">http://samples.ffmpeg.org/V-codecs/WVC1/Test_1440x576_WVC1_6Mbps.wmv</a>
<a href="http://samples.ffmpeg.org/asf-wmv/asf_with_chapters.wmv">http://samples.ffmpeg.org/asf-wmv/asf_with_chapters.wmv</a>
We reproduce this with the command found in the mailing list:
mpv --hwdec=vdpau --vo=vdpau
And with a gstreamer pipeline using the Fluendo video acceleration codec:
gst-launch-0.10 playbin2 uri=file://[...]
Both ways reproduce the same garbage, when it happens.</pre>
