Hey @parvendraintigate did you find any solution for this? I also faced the same issue on my side.

harjeetk commented 6 years ago

I have test it takes maximum 16 images to merge so you can create the different video of different images set and them merge according to them.

But have to make final video of more than 16 selected images and video to combine at a time

Finally I found out the cause and was my bad! The problem was that I was looping through AVMutableCompositionTrack. So that each video was on a different track and probably that caused a lack of resources. Right now I created only 2 tracks: 1 for video and 1 for audio. All my videos are stitched with time ranges.

Just put this following code top of the loop

let videoCompositionTrack = mixComposition.addMutableTrack(withMediaType: AVMediaType.video, preferredTrackID: Int32(kCMPersistentTrackID_Invalid))
