Hevc decoder reports invalid cu_qp_delta
|Reported by:||Jovasa||Owned by:|
|Blocking:||Reproduced by developer:||no|
|Analyzed by developer:||no|
Summary of the bug:
HEVC decoder incorrectly reports a invalid cu_qp_delta when it claiming it should be in range [-26, 25], additionally the video is decoded incorrectly creating green artifacts or in extreme cases turning the video completely green. However the reference decoder has no problem decoding the video implying the HEVC decoder in ffmpeg is incorrect.
How to reproduce:
% ffmpeg -i input output ffmpeg version: master

Note: See TracTickets for help on using tickets.
After further investigation into the issue and looking through the standard it seems that ffmpeg and OpenHEVC are in fact working correctly and the reference encoder is incorrect.
