How can I cut videos from multiple videos and merge them in iPhone programmatically

I have a requirement where I need to cut t开发者_如何学Che video between some selected time frames from different videos and merge them to make those a single video. How can I achieve this in iPhone programmatically. Are there any API's available?

I didnt use them my self but yes there are available APIs to help you do this.

Have a look at AV Foundation programming guideline

I also recommend you to check the WWDC 2010 video session "Editing media with AV Foundation"
