NAME

       MP4AddTrack - Add a user defined track

SYNTAX

       #include <mp4.h>

       MP4TrackId MP4AddTrack(
            MP4FileHandle hFile,
            const char* type
       )

ARGUMENTS

       hFile  Specifies the mp4 file to which the operation applies.

       type   Specifies the type of track to be added.

RETURN VALUES

       Upon   success,  the  track  id  of  the  new  track.  Upon  an  error,
       MP4_INVALID_TRACK_ID.

DESCRIPTION

       MP4AddTrack adds a user defined track to the mp4 file. Care  should  be
       taken  to  avoid  any  of  the  standardized track type names. A useful
       convention is use only uppercase  characters  for  user  defined  track
       types.  The  string  should  be exactly four characters in length, e.g.
       "MINE".

       Note this should not be used to  add  any  of  the  known  track  types
       defined in the MP4 standard (ISO/IEC 14496-1:2001).
