[FFmpeg-devel] [PATCH V2] ffmpeg: fix video_delay warning for HEVC/MPEG4 decoding

[Jun Zhao]

For HEVC/MPEG4, we also need video_delay from the decoder, when decoding
some HEVC/MPEG4 clips, got numerous log like:
"video_delay is larger in decoder than demuxer", similar ticket: #3711

fix ticket: #6019
