DESCRIPTION

27       MP4AddTrack adds a user defined track to the mp4 file. Care  should  be
28       taken  to avoid any of the standardized track type names. A useful con‐
29       vention is use only uppercase characters for user defined track  types.
30       The string should be exactly four characters in length, e.g. "MINE".
31
32       Note  this  should  not  be  used  to  add any of the known track types
33       defined in the MP4 standard (ISO/IEC 14496-1:2001).
