您好，我正在尝试在我的 iPhone 应用程序上播放视频。该代码播放本地文件但因错误而崩溃 “由于未捕获的异常‘NSInvalidArgumentException’而终止应用程序，原因:‘AVPlayerItem 不能与多个 AVPlayer 实例相关联’”当用于从服务器流式传输视频时。此外，该链接在浏览器中流式传输视频绝对没问题，但我无法在应用程序中播放视频。请帮忙 。 谢谢

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

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