I think the steps would be something like:
1. Use a NAL parser to find and remove the SPS and PPS NALs in the sample data
and build lists of them
2. Patch codec_data to remove any existing SPS entries, PPS entries, the
numberOfSequenceParameterSets and the numberOfPictureParameterSets fields
3. Append (numberOfSequenceParameterSets | 0xE0) to codec_data
4. For each SPS NAL: append sequenceParameterSetLength and SPS NAL to
codec_data
5. Append numberOfPictureParameterSets to codec_data
6. For each PPS NAL: append pictureParameterSetLength and PPS NAL to codec_data
7. Push new codec_data downstream
8. profit! :)
