2 * QuickTime MOV file parser
3 * copyright(c) 2001 A'rpi
4 * additional work by Atmos
5 * based on TOOLS/movinfo.c by A'rpi & Al3x
6 * compressed header support from moov.c of the openquicktime lib.

13 * (Complete list of documentation at http://developer.apple.com/quicktime/)
14 * MP4-Lib sources from http://mpeg4ip.sf.net/ might be useful for .mp4

17 * All sort of Stuff about MPEG4:
18 * http://www.cmlab.csie.ntu.edu.tw/~pkhsiao/thesis.html
19 * I really recommend N4270-1.doc and N4270-2.doc which are exact specs
