this (rather large) procedure is more or less explained in a paragraph in
"The MPEG-4 Book", dealing with the MP4 file format. If you take a look at
the history of this list, you will probably find some interesting tools that
can help you (to be more specific, look at
http://lists.mpegif.org/pipermail/mp4-tech/2003-January/001629.html).
