1 /*
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.
7 *
8 * references: http://openquicktime.sf.net/, http://www.heroinewarrior.com/
9 * http://www.geocities.com/SiliconValley/Lakes/2160/fformats/files/mov.pdf
10 * (above URL no longer works, file mirrored somewhere? ::atmos)
11 * The QuickTime File Format PDF from Apple:
12 * http://developer.apple.com/techpubs/quicktime/qtdevdocs/PDF/QTFileFormat.pdf
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
15 * as well as .mov specific stuff.
16 *
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
20 * of the MP4-File Format and the MPEG4 Specific extensions. ::atmos
