26 | /* |
27 | * First version by Francois Revol revol@free.fr | |
28 | * | |
29 | * Features and limitations: | |
30 | * - reads most of the QT files I have (at least the structure), | |
31 | * the exceptions are .mov with zlib compressed headers ('cmov' section). It shouldn't be hard to implement. | |
0147f198 | 32 | * FIXED, Francois Revol, 07/17/2002 |
6cea494e ZK |
33 | * - ffmpeg has nearly none of the usual QuickTime codecs, |
34 | * although I succesfully dumped raw and mp3 audio tracks off .mov files. | |
35 | * Sample QuickTime files with mp3 audio can be found at: http://www.3ivx.com/showcase.html | |
36 | * - .mp4 parsing is still hazardous, although the format really is QuickTime with some minor changes | |
37 | * (to make .mov parser crash maybe ?), despite what they say in the MPEG FAQ at | |
38 | * http://mpeg.telecomitalialab.com/faq.htm | |
39 | * - the code is quite ugly... maybe I won't do it recursive next time :-) | |
40 | * | |
41 | * Funny I didn't know about http://sourceforge.net/projects/qt-ffmpeg/ | |
42 | * when coding this :) (it's a writer anyway) | |
43 | * | |
