mov_codec_id is now able to set AVMEDIA_TYPE_DATA to the st->codec->codec_type field when the input is of type AVMEDIA_TYPE_DATA; previously it used AVMEDIA_TYPE_SUBTITLE as the value to set in that case. Signed-off-by: Erkki Seppälä Signed-off-by: OZOPlayer --- libavformat/mov.c | 18 +

It does it only when the chnl box is to be written.

It has the codec id AV_CODEC_ID_META and type of AVMEDIA_TYPE_DATA. This codec basically passes the data forward and is used for referring timed meta data tracks by a codec. It is useful for dealing with the metadata in a similar way as other kinds of codecs. Signed-off-by: Erkki Seppälä Signed-

[FFmpeg-devel] [PATCH v2 01/18] avformat/movenc: added ability to use original stream ids as track ids instead of regenerating them

Sometimes it's useful to be able to define the exact track numbers in the generated track, instead of always beginning at track id 1. Using the option use_stream_ids_as_track_ids now copies the use stream ids to track ids. Dynamically generated tracks (ie. tmcd) have their track numbers defined as
