This section documents the reading and writing of ISOBMF (MP4, 3GPP, AVC, HEVC HEIF ...) The library supports:
All the READ function in this API can be used in EDIT/WRITE mode. However, some unexpected errors or values may happen in that case, depending on how much modifications you made (timing, track with 0 samples, ...). On the other hand, none of the EDIT/WRITE functions will work in READ mode.
The output structure of a edited file will sometimes be different from the original file, but the media-data and meta-data will be identical. The only change happens in the file media-data container(s) during edition
When editing the file, you MUST set the final name of the modified file to something different. This API doesn't allow file overwriting.
