So, I changed the API to accept the DOVI configuration record, but
actually getting that record into hevcdec isimpossible given the current
design of FFmpeg where stream-level properties are not mode available to
the decoder. Possibilities:
1. Add patch to propagate stream-level properties to
AVCodecContext.coded_side_data automatically
2. Add patch to automatically propagate stream-level properties to each
AVPacket somehow?
3. Have the code read the profile from the AVPacket even though the side
data doesn't exist for them, and let this just be an open bug.
4. Something else?
Thoughts?
