Merging two m4v Movie Files Using AVMutableComposition - Videos Will Not Merge

Question

I am using the below code to try and merge two m4v files stored in the documents folder :

CMTime insertionPoint = kCMTimeZero;
NSError * error = nil;

AVMutableC         


        

Answer 1

Ok - so I eventually got this working by using individual AVMutableComposition tracks and then setting a mutablecomposition for audio and one for video.
