The numbers of streams are already known before selecting a track (see bgav_num_audio_streams and bgav_num_video_streams. Note that by default, all streams are muted, which means that you cannot skip the stream selection in your application.
◆ bgav_stream_action_t
Stream action.
This is used to tell the decoder, what to do with the stream. Only supported actions right now are mute (default) and decode.
