| void* CodedBitstreamContext::priv_data |
Internal codec-specific data.
This contains any information needed when reading/writing bitsteams which will not necessarily be present in a fragment. For example, for H.264 it contains all currently visible parameter sets - they are required to determine the bitstream syntax but need not be present in every access unit.

| CodedBitstreamUnitType* CodedBitstreamContext::decompose_unit_types |
Array of unit types which should be decomposed when reading.
Types not in this list will be available in bitstream form only. If NULL, all supported types will be decomposed.
