I need an objective c wrapper around FFMpeg which:
1. Compiles in iOS 5/5.1.
2. Can crop an Audio/Video file in certain period.
3. Can also make the Audio/Video loop for certain amount of times.
4. Extract the audio out of a video file.
5. All outputs should be saved into any kind of audio type (mp3, amr, wav, ..).
6. Should be quick enough.
7. Should be able to run in threads.
8. Should notify of output progress in a delegate.
The output file should use as minimum categories or dependencies as possible.
I need time estimations and fixed price for that.
