View Source Membrane.MP4.MovieBox.MovieExtendsBox (Membrane MP4 plugin v0.22.1)

The module provides a function that assembles an MPEG-4 movie extends box (mvex atom).

The movie extends box provides information about movie fragment boxes in case when media data is fragmented (for example in CMAF). It has to contain as many track extends box (trex atoms) as there are tracks in the movie box.

For more information about the movie extends box, refer to ISO/IEC 14496-12.
