- * 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),
- *   the exceptions are .mov with zlib compressed headers ('cmov' section). It shouldn't be hard to implement.
- *   FIXED, Francois Revol, 07/17/2002
- * - 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 :-)
- * - seek is not supported with files that contain edit list
- *
- * Funny I didn't know about http://sourceforge.net/projects/qt-ffmpeg/
- * when coding this :) (it's a writer anyway)
- *
