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*.

Field Documentation

For streams with AV_DISPOSITION_ATTACHED_PIC disposition, this packet will contain the attached picture.

decoding: set by libavformat, must not be modified by the caller. encoding: unused

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.

Real base framerate of the stream.

This is the lowest framerate with which all timestamps can be represented accurately (it is the least common multiple of all framerates in the stream). Note, this value is just a guess! For example, if the time base is 1/90000 and all frames have either approximately 3600 or 1800 timer ticks, then r_frame_rate will be 50/1.
