◆ codec

const struct CodedBitstreamType* CodedBitstreamContext::codec

Internal codec-specific hooks.

Definition at line 166 of file cbs.h.

◆ priv_data

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.
