Overview
Version 3.1
During the preparation of the MPEG-4 file for streaming, one hint track
is added to the MPEG-4 file for each track whose media will be streamed
over RTP. The hint tracks within the MPEG-4 file provide the
information needed to turn the media into RTP packets.
These hint tracks are part of the MPEG-4 atom structure, and are similar
to Apples QuickTime file format.
