Field Documentation

void* CodedBitstreamContext::log_ctx
const struct CodedBitstreamType* CodedBitstreamContext::codec
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.

int CodedBitstreamContext::nb_decompose_unit_types

Length of the decompose_unit_types array.

Definition at line 178 of file cbs.h.

Referenced by cbs_read_fragment_content().

int CodedBitstreamContext::trace_enable
int CodedBitstreamContext::trace_level

Log level to use for trace output.

From AV_LOG_*; defaults to AV_LOG_TRACE.
