◆ streams

AVStream** AVStreamGroup::streams

A list of streams in the group.

New entries are created with avformat_stream_group_add_stream().

  • demuxing: entries are created by libavformat on group creation. If AVFMTCTX_NOHEADER is set in ctx_flags, then new entries may also appear in av_read_frame().
  • muxing: entries are created by the user before avformat_write_header().
