6cea494e | 45 | * Features and limitations: |
5ca1d879 | 46 | * - reads most of the QT files I have (at least the structure), |
6cea494e | 47 | * Sample QuickTime files with mp3 audio can be found at: http://www.3ivx.com/showcase.html |
6cea494e | 48 | * - the code is quite ugly... maybe I won't do it recursive next time :-) |

50 | * Funny I didn't know about http://sourceforge.net/projects/qt-ffmpeg/ |
