Changes in v4:
- Always insert SEI from extradata before IRAP (same approach as original
code). New SEIs are inserted before IRAP, or forwarded after the nal unit.
- Before writing each VCL, I check whether the PPS has already been
signalled in the CVS. If it hasn't been signalled, I append the PPS
before the nal
unit.
- Use raw pointers instead of AVBufferRef for storing parameter sets.
- Parse extradata directly from HVCC.
- Added extra fate tests where the parameter sets are changing.
For testing I looked at all the datasets from fate-suite/hevc-conformance. I
used the same approach as the current fate test (i.e. put the data into mp4
container and then back to annexb)
