◆ nb_interleaved_streams

int FFFormatContext::nb_interleaved_streams

Number of streams relevant for interleaving.

Muxing only.

◆ interleave_packet

int(* FFFormatContext::interleave_packet) (struct AVFormatContext *s, AVPacket *pkt, int flush, int has_packet)

The interleavement function in use.

Always set for muxers.

PacketList FFFormatContext::packet_buffer

This buffer is only needed when packets were already buffered but not decoded, for example to get the codec parameters in MPEG streams.

◆ data_offset

int64_t FFFormatContext::data_offset

offset of the first packet

◆ raw_packet_buffer

PacketList FFFormatContext::raw_packet_buffer

Raw packets from the demuxer, prior to parsing and decoding.

This buffer is used for buffering packets until the codec can be identified, as parsing cannot be done without knowing the codec.

◆ parse_queue

PacketList FFFormatContext::parse_queue

Packets split by the parser get queued here.

◆ parse_pkt

AVPacket* FFFormatContext::parse_pkt

The generic code uses this as a temporary packet to parse packets or for muxing, especially flushing.

For demuxers, it may also be used for other means for short periods that are guaranteed not to overlap with calls to av_read_frame() (or ff_read_packet()) or with each other. It may be used by demuxers as a replacement for stack packets (unless they call one of the aforementioned functions with their own AVFormatContext). Every user has to ensure that this packet is blank after using it.
