I have an app that has some video editing tools. I mix photos and videos and I am running into an odd issue. When i arrange a video composition with a video, then a photo, then back to the video it plays fine until the transition back to the video at which point it freezes! I still hear the audio, and if i seek around the video starts playing again. I dont know how I can error check this! Anyone have any ideas?

Are you evaluating **ALL** possible return values and `NSError` instances that are possibly filled by the `AVFoundation` methods? – Till Oct 31 '12 at 21:05

The only method that Im using that uses NSError is the insertTimeRange: timeRangeInAsset method, and the error i pass is always comes bak nil – box86rowh Oct 31 '12 at 22:01

OK, in my tests, my video plays properly if the track i set aside for the photo has at least 1 video asset on it. So it breaks it if I have transition to or from a video track with nothing on it. – box86rowh Oct 31 '12 at 22:07

The fix more my situation, I created a 1 second clip of blackness and injected that into my composition at the photo spot and now it works fine
