嗨，我正在尝试在我的 iphone 应用上播放视频。该代码播放本地文件，但在用于从服务器流式传输视频时出现错误“由于未捕获的异常‘NSInvalidArgumentException’导致应用程序终止，原因：‘一个 AVPlayerItem 不能与多个 AVPlayer 实例关联’”而崩溃。此外，该链接在浏览器中流式传输视频绝对正常，但我无法在应用程序中播放视频。请帮忙 。谢谢

Had same issue, try setting ContentURL after Setting the SourceType like below,

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

首先，您必须告知播放器您设置视频文件内容的源类型；像这样

这是两种类型的网址；如果 url 是这样的，你写这个函数

 NSString *aStr=@"http://www.my url like this.com/video/videos/review/Michale JACKSON  AUDIENCE Comment.mp4";   

aStr = [aStr stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

或（第二个）

NSString *aStr=@"http://www.normal url.com/video.mp4"

// after add your url string to this url

NSURL *url=[NSURL URLWithString:aStr];
MPMoviePlayerViewController *MPlayer = [[MPMoviePlayerViewController alloc]init];
MPlayer.moviePlayer.movieSourceType = MPMovieSourceTypeStreaming;
[MPlayer.moviePlayer setContentURL:url];
[self presentMoviePlayerViewControllerAnimated:MPlayer];

不是问题的直接答案，但如果您在尝试更新 contentURL 后收到此错误，请在解决问题之前调用 stop()。

moviePlayerController.stop()
moviePlayerController.movieSourceType = .File
moviePlayerController.contentURL = newURL
