DESCRIPTION

27       MP4DeleteTrack  deletes  the  control  information  associated with the
28       specified track. The trackId will become invalid if this call succeeds.
29
30       Note that the samples associated with this track are not  deleted  with
31       this  call.  This can be accomplished via MP4Optimize(). The reason for
32       this is that multiple tracks can reference the same samples so a global
33       view must be taken when deleting them.
