你好我想在我的iPhone应用程序流的视频。 该代码可播放本地文件但有错误崩溃“终止应用程序由于未捕获的异常‘NSInvalidArgumentException’，理由是：‘一个AVPlayerItem不能AVPlayer的多个实例相关联的’”用于从服务器流式播放视频的时候。 另外，链接流的视频在浏览器中的精绝，但不过我不能够在应用程序中播放视频。 请帮忙 。 谢谢

Answer 1:

有同样的问题，请尝试设置sourceType像下面后设置的contentURL，

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

Answer 2:

这可能是一个问题MovieSourceType ; 您正在播放本地文件，但使用MPMovieSourceTypeStreaming ; 刚刚修改的类型，然后再试一次

Answer 3:

我已经使用moviePlayerController.movi​​eSourceType = MPMovieSourceTypeUnknown其作品对我..试试吧..

Answer 4:

首先，你必须通知到玩家源类型ofter您设置视频文件的内容; 像这样

下面是两种类型的网址; 如果URL是这样你写此功能

 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];

Answer 5:

如果你不尝试更新的contentURL，呼吁停止后出现此错误（）直接回答这个问题，但在此之前解决问题。

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