Box Type: 'tref'
Container: {@link TrackBox} ('trak')
Mandatory: No
Quantity: Zero or one
This box provides a reference from the containing track to another track in the presentation. These references
are typed. A 'hint' reference links from the containing hint track to the media data that it hints. A content
description reference 'cdsc' links a descriptive or metadata track to the content which it describes.
Exactly one Track Reference Box can be contained within the Track Box.
If this box is not present, the track is not referencing any other track in any way. The reference array is sized
to fill the reference type box. |
