The data references of a track constitute the track's media. Each track has a single media data structure. Specifies the media for an operation. Your application obtains a media identifier from such Movie Toolbox functions as NewTrackMedia and GetTrackMedia (described on page 2-153 of Inside Macintosh: QuickTime and page 2-206 of Inside Macintosh: QuickTime, respectively).<P><HR><P><!-- ======== INNER CLASS SUMMARY ======== --><!-- =========== FIELD SUMMARY =========== --><A
