A module providing a function assembling an MPEG-4 movie box.

The movie box (moov) is a top-level box that contains information about a presentation as a whole. It consists of:

  The movie header contains media-independent data, such as the number of tracks, volume, duration or timescale (presentation-wide).

• one or more track box (trak atom)

• zero or one movie extends box (mvex atom)

For more information about movie box and its contents, refer to documentation of Membrane.MP4.MovieBox submodules or to ISO/IEC 14496-12.
