Detailed Description

The bitstream filter state.

This struct must be allocated with av_bsf_alloc() and freed with av_bsf_free().

The fields in the struct will only be changed (by the caller or by the filter) as described in their documentation, and are to be considered immutable otherwise.

Field Documentation

◆ av_class

const AVClass* AVBSFContext::av_class

A class for logging and AVOptions.

Definition at line 53 of file bsf.h.

◆ filter

const struct AVBitStreamFilter* AVBSFContext::filter

The bitstream filter this context is an instance of.

Definition at line 58 of file bsf.h.

Referenced by bsf_list_item_name(), ff_stream_add_bitstream_filter(), log_slave(), and write_packets_from_bsfs().

◆ internal

AVBSFInternal* AVBSFContext::internal

Opaque libavcodec internal data.

Must not be touched by the caller in any way.

Definition at line 64 of file bsf.h.

◆ priv_data

void* AVBSFContext::priv_data

Opaque filter-specific private data.

If filter->priv_class is non-NULL, this is an AVOptions-enabled struct.

◆ par_in

AVCodecParameters* AVBSFContext::par_in

◆ par_out

AVCodecParameters* AVBSFContext::par_out

◆ time_base_in
