I'm using AVFoundation to crop and rotate a video, but I'm getting a SIGABRT error when setting the AVAssetExporter's videoComposition property.

assetExport.videoComposition = videoComposition;

Any ideas?

Thanks, Daniel.

Are you setting the video composition on your AVPlayer's playerItem as well? Temporarily setting your playerItem.videoComposition to nil should prevent the crash. AVFoundation doesn't seem to like sharing the same composition between two different objects. I know this is an old question, but I've spent 2 days debugging this, hope it will help someone out in the future.
