Detailed Description

Stream structure.

New fields can be added to the end with minor version bumps. Removal, reordering and changes to existing fields require a major version bump. sizeof(AVStream) must not be used outside libav*.

Examples:
demuxing_decoding.c, muxing.c, qsvdec.c, remuxing.c, transcode_aac.c, and transcoding.c.

int AVStream::id
AVCodecContext* AVStream::codec

Codec context associated with this stream.

Allocated and freed by libavformat.

  • decoding: The demuxer exports codec information stored in the headers here.
  • encoding: The user sets codec information, the muxer writes it to the output. Mandatory fields as specified in AVCodecContext documentation must be set even if this AVCodecContext is not actually used for encoding.
Examples:
demuxing_decoding.c, filtering_audio.c, filtering_video.c, muxing.c, qsvdec.c, remuxing.c, transcode_aac.c, and transcoding.c.

AVRational AVStream::time_base

This is the fundamental unit of time (in seconds) in terms of which frame timestamps are represented.

decoding: set by libavformat encoding: May be set by the caller before avformat_write_header() to provide a hint to the muxer about the desired timebase. In avformat_write_header(), the muxer will overwrite this field with the timebase that will actually be used for the timestamps written into the file (which may or may not be related to the user-provided one, depending on the format).

Examples:
filtering_audio.c, filtering_video.c, muxing.c, remuxing.c, transcode_aac.c, and transcoding.c.

AVPacketSideData* AVStream::side_data

An array of side data that applies to the whole stream (i.e.

the container does not allow it to change between packets).

There may be no overlap between the side data in this array and side data in the packets. I.e. a given side data is either exported by the muxer (demuxing) / set by the caller (muxing) in this array, then it never appears in the packets, or the side data is exported / sent through the packets (always in the first packet where the value becomes known or changes), then it does not appear in this array.

  • demuxing: Set by libavformat when the stream is created.
  • muxing: May be set by the caller before avformat_write_header().
