 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
 }}}
