New description:
Summary of the bug:
When FFmepg is demuxing MP4 where the STSD information does not match the
bitstream PPS/SPS information a corrupted bitstream is generated when
trying to extract the video bitstream.
I assume the demuxer is passing the PPS/SPS from the MP4 container instead
of the HEVC bitstream. Perhaps it is passing the PPS/SPS of the HEVC
before the one from the STSD.
Setup:
Ubuntu 24.04
FFmpeg 6.1.1
