How to detect if a video file was recorded in portrait orientation, or landscape in iOS

Question

I am using AlAssetsGroup enumerateAssetsAtIndexes to list the assets in the Photos (Camera) app. For a given video asset I want to determine whether it was shot

If you do not want to use AVFoundation Framework just to get the orientation of the recorded video then try it out

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo: (NSDictionary *)info {

   NSString *orientation;

   NSString *videoPath = [[info objectForKey:UIImagePickerControllerMediaURL] path];
   NSURL *myURL = [[NSURL alloc] initFileURLWithPath:videoPath];

   self.movieController = [[MPMoviePlayerController alloc] initWithContentURL:myURL];       
   UIImage *thumbImage = [movieController thumbnailImageAtTime:1.0 timeOption:MPMovieTimeOptionNearestKeyFrame];

   float width = thumbImage.size.width;
   float height = thumbImage.size.height;

   if (width > height){

        orientation  = @"Landscape";

      }else{

         orientation  = @"Portrait";
      }

 [self dismissViewControllerAnimated:YES completion:nil];

}
