VP9 decoding broken by webrtc
.org 49 update - YCb Cr pointers are off
Seen on AppRTC
This is the video from Canary -> Firefox I also see the same thing on Chrome Release -> Firefox.
Caused by the Webrtc 49 update. pc_test.html has been updated to include a force-vp9 option which shows the problem. The plane pointers for YCbCr on VP9 decode appear to be wrong.
Depends on: 1250356
Priority: -- → P1
