transmuxVideo

Sets whether to transmux the media items' video tracks.

The default value is false.

If the Composition contains one MediaItem, the value set is ignored. The video track will only be transcoded if necessary.

If the input Composition contains multiple media items, all the video tracks are transcoded by default. They are all transmuxed if transmuxVideo is true. Transmuxed tracks must be compatible (typically, all the MediaItem instances containing the track to transmux are concatenated in a single EditedMediaItemSequence and have the same sample format for that track).
