+ * First version by Francois Revol revol@free.fr
+ * 
+ * Features and limitations:
+ * - reads most of the QT files I have (at least the structure), 
+ *   the exceptions are .mov with zlib compressed headers ('cmov' section). It shouldn't be hard to implement.
+ * - ffmpeg has nearly none of the usual QuickTime codecs,
+ *   although I succesfully dumped raw and mp3 audio tracks off .mov files.
+ *   Sample QuickTime files with mp3 audio can be found at: http://www.3ivx.com/showcase.html
+ * - .mp4 parsing is still hazardous, although the format really is QuickTime with some minor changes
+ *   (to make .mov parser crash maybe ?), despite what they say in the MPEG FAQ at
+ *   http://mpeg.telecomitalialab.com/faq.htm
+ * - 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/techpubs/quicktime/qtdevdocs/QTFF/qtff.html
