Programmatically make video from UIImages for play

问题:

How can I programmatically create a video file from a bunch of UIImages?

I want to do this so I can play back a slideshow with MPMoviePlayer and stream via AirPlay.

Ideally I'd like to be able to set a duration for each image and do simple fade transitions between them.

Check out the AVAssetWriter documentation for encoding your own movies on an iOS device.

Another hint might be this question on SO: How do I use AVAssetWriter?
