我正在从库中选择一个视频。视频不在 iphone 4s(ios5) 中播放，它在 iphone 4(ios4) 中播放。视频为 .mov 格式。我正在静态拍摄 mp4 视频，它正在播放。有没有原因？请给任何建议。提前致谢

movieplayer=[[MPMoviePlayerController alloc] initWithContentURL:videourl];

    NSLog(@"url--%@",videourl);
if([movieplayer respondsToSelector:@selector(view)])
 {
    movieplayer.controlStyle = MPMovieControlStyleFullscreen;
    [movieplayer.view setFrame:self.view.bounds];
    [self.view addSubview:movieplayer.view];
     movieplayer.shouldAutoplay=true;
    [movieplayer play];
 }

它显示黑屏
