|When cloning a hint track, this parameter specifies the track id of the reference track in the destination file.|

MP4CloneTrack creates a new track to an mp4 file that is a copy of an existing track with respect to the track media type, and other control information.
Note this function does not copy the media samples of the source track to the new track. If you want to do that use MP4CopyTrack() instead.
