Which frame work I have to use for video format conversion

I have a requirement to conver开发者_如何转开发t the format of video to another format such as .mov file to .wmv format, .mov to mp4/mp3/mpeg-1 etc, which frame work I have to use in cocoa for video format conversion.

can I use QuickTime Framework for this purpose.

Any help would be appreciated.

Thanks, Akbar

If you want to stay with pure Cocoa then you will need QTKit framework. However, unless things have changed with Lion, a lot of functionality is missing from QuickTime framework.

If you go with QuickTime then you probably need to use the CoreVideo framework as well.

Alternatively, you could consider the LGPL libavcodec library.
