AVFoundationErrorDomain Code=-11832 "Cannot Open"

I'm using GPUImage to process a video and then save it as a Mov file, once the video is processed, it saves correctly to my video library.

UISaveVideoAtPathToSavedPhotosAlbum (pathToMovie, self, @selector(video:didFinishSavingWithError:contextInfo:), NULL);

in the didFinishSavingWithError function take the video URL and try to run it through NSGIF

• (void)video: (NSString *) videoPath didFinishSavingWithError: (NSError *) error contextInfo: (void *) contextInfo;

  NSURL *fileURL = [NSURL fileURLWithPath:videoPath];
  [NSGIF createGIFfromURL:fileURL withFrameCount:30 delayTime:.010 loopCount:0 completion:^(NSURL *GifURL) {
  NSLog(@"Finished generating GIF: %@", GifURL);
  }];

  if (error) {
  NSLog(@"Error Saving Video To Library: %@", error);
  // Do anything needed to handle the error or display it to the user
  } else {
  NSLog(@"Saved Video To Library:");
  }

}

However I constantly get the following error

Error copying image: Error Domain=AVFoundationErrorDomain Code=-11832 "Cannot Open" UserInfo={NSUnderlyingError=0x12750ed50 {Error Domain=NSOSStatusErrorDomain Code=-12431 "(null)"}, NSLocalizedFailureReason=This media cannot be used., NSLocalizedDescription=Cannot Open}
2016-03-24 16:06:37.191 PhotoBooth[1123:444110] Error copying image and no previous frames to duplicate

Any idea what is causing this?

Were you able to solve this yet? Im having the same problem.

This definitely sounds like an issue with your source video. Can you put a breakpoint before attempting to convert it to GIF and check the actual video file?

Same error here as well, used to work until I upgraded to ios11, but might be code changes too I don't know.

native video (iphone make) is OK when convert to gif, but my mov is created from a group
of images, it goes wrong at - (nullable CGImageRef)copyCGImageAtTime:(CMTime)requestedTime actualTime:(nullable CMTime *)actualTime error:(NSError * _Nullable * _Nullable)outError

I compare their exif info, is different, maybe the problem
