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*.

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, remuxing.c, and transcode_aac.c.
