/*
* First version by Francois Revol revol@free.fr
* Seek function by Gael Chardon gael.dev@4now.net
- *
- * Features and limitations:
- * - reads most of the QT files I have (at least the structure),
- * Sample QuickTime files with mp3 audio can be found at: http://www.3ivx.com/showcase.html
- * - the code is quite ugly... maybe I won't do it recursive next time :-)
- *
- * Funny I didn't know about http://sourceforge.net/projects/qt-ffmpeg/
- * when coding this :) (it's a writer anyway)
- *
- * Reference documents:
- * http://www.geocities.com/xhelmboyx/quicktime/formats/qtm-layout.txt
- * Apple:
- * http://developer.apple.com/documentation/QuickTime/QTFF/
- * http://developer.apple.com/documentation/QuickTime/QTFF/qtff.pdf
- * QuickTime is a trademark of Apple (AFAIK :))
