Field Documentation

nb_interleaved_streams

int AVFormatInternal::nb_interleaved_streams

Number of streams relevant for interleaving.

Muxing only.

Definition at line 77 of file internal.h.

packet_buffer

struct PacketList* AVFormatInternal::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.

Definition at line 84 of file internal.h.

Referenced by avformat_find_stream_info().

packet_buffer_end

struct PacketList* AVFormatInternal::packet_buffer_end

Definition at line 85 of file internal.h.

Referenced by avformat_find_stream_info().

data_offset

int64_t AVFormatInternal::data_offset

offset of the first packet

Definition at line 88 of file internal.h.

Referenced by estimate_timings_from_bit_rate().

raw_packet_buffer

struct PacketList* AVFormatInternal::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.

Definition at line 96 of file internal.h.

raw_packet_buffer_end

struct PacketList* AVFormatInternal::raw_packet_buffer_end

Definition at line 97 of file internal.h.

parse_queue

struct PacketList* AVFormatInternal::parse_queue

Packets split by the parser get queued here.

Definition at line 101 of file internal.h.

parse_queue_end

struct PacketList* AVFormatInternal::parse_queue_end

Definition at line 102 of file internal.h.

parse_pkt

AVPacket* AVFormatInternal::parse_pkt

The generic code uses this as a temporary packet to parse packets; 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.

Definition at line 115 of file internal.h.

pkt

AVPacket* AVFormatInternal::pkt

Used to hold temporary packets.

Definition at line 120 of file internal.h.

Referenced by avformat_find_stream_info(), and estimate_timings_from_pts().

raw_packet_buffer_remaining_size

int AVFormatInternal::raw_packet_buffer_remaining_size

Definition at line 125 of file internal.h.

Referenced by avformat_alloc_context().

offset

int64_t AVFormatInternal::offset

Offset to remap timestamps to be non-negative.

Expressed in timebase units.

initialized

int AVFormatInternal::initialized

Whether or not avformat_init_output has already been called.

Definition at line 155 of file internal.h.
