_itemFailedToPlayToEnd: {
   kind = 1;
   new = 2;
   old = 0;
  }

以下是我的代码,

NSURL *fileURL = [NSURL URLWithString:_videoUrl];
NSLog(@" fileURL: %@",fileURL);
_moviePlayer =  [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
_moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
UIWindow *backgroundWindow = [[UIApplication sharedApplication] keyWindow];
[_moviePlayer.view setFrame:backgroundWindow.frame];
[backgroundWindow addSubview:_moviePlayer.view];
[_moviePlayer prepareToPlay];
[_moviePlayer play];

我该如何解决这个问题？
