Description
Summary of the bug:
Certain VP9 bit-streams show corruption when decoding with ffvp9. Decoding with libvpx-vp9 seem to be fine.
How to reproduce:
ffplay vp9aq_corruption.webm
[Corruption is visible in certain frames]
ffplay vp9aq_corruption.webm -vcodec libvpx-vp9
[No corruption here]
The corruption may be related to the segmentation feature sinc e the bit-stream uses segmentation to achieve aq.
