Bug#743701: libva1=1.3.0-1 with i965 makes all video "solid black" with mpv --hwdec=vaapi

[Kevin Mitchell]

Package: i965-va-driver
Version: 1.2.2-2
Severity: normal

With the 1.3.0-1 version currently in unstable and i965-va-driver=1.2.2-2 on ivy bridge chip,

$ mpv vc1.mkv --no-config --no-resume-playback --hwdec=vaapi --vo=opengl

results in a solid black screen while the sound works. The vc1.mkv
clip can be found at [1]. I found this happens with every hardware
decodable clip I tried including h264 clips. The vc1 clip however
neatly demonstrates that the problem is specifically with hardware
decoding as seeking with left and right keys leads to (unrelated) decoding errors
and a fallback to software decoding, at which point the video
reappears!

The problem goes away on downgrading to libva1=1.2.1-2.
