        /* Specify the URL that points to the movie file. */
        [self.moviePlayerController setContentURL:url];


        [self.moviePlayerController setMovieSourceType:MPMovieSourceTypeStreaming]; // for streaming



        self.moviePlayerController.controlStyle = MPMovieControlStyleEmbedded;

        // [self.videoPlayer setMovieSourceType:MPMovieSourceTypeStreaming];

      // self.moviePlayerController.shouldAutoplay = YES;

        [self.moviePlayerController.view setFrame: CGRectMake(0, 0, 320,160)];



        [self.moviePlayerController setFullscreen:NO animated:YES];

        [self.moviePlayerController view].backgroundColor = [UIColor lightGrayColor];

        [self.view addSubview:self.moviePlayerController.view];

        [self.view bringSubviewToFront:self.moviePlayerController.view];
        [self.moviePlayerController prepareToPlay];

嗨,我想在我的iPhone应用程序上流式传输视频.代码播放本地文件但崩溃时出现错误"由于未捕获的异常终止应用程序'NSInvalidArgumentException',原因:'当用于从服务器流式传输视频时,'AVPlayerItem不能与多个AVPlayer实例关联'".此外,链接在浏览器中流媒体视频绝对正常但是我无法在应用中播放视频.请帮忙 .谢谢

有同样的问题,尝试在设置SourceType之后设置ContentURL,如下所示,

moviePlayerController_ = [[MPMoviePlayerViewController alloc] init];
moviePlayerController_.movieSourceType = MPMovieSourceTypeStreaming;
[moviePlayerController_.moviePlayer setContentURL:url];

这可能是一个问题MovieSourceType；您正在播放本地文件但使用MPMovieSourceTypeStreaming; 只需修改类型并重试
