Answer 1

有同样的问题，尝试设置后，像下面的SourceType设置ContentURL，

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

Answer 2

这可能是一个MovieSourceType的问题; 你正在播放本地文件，但使用MPMovieSourceTypeStreaming ; 只需修改types，然后重试

Answer 3

我已经使用moviePlayerController.movi​​eSourceType = MPMovieSourceTypeUnknown其作品为我..试试吧..

Answer 4

首先你必须通知玩家你设定的video文件内容的来源types; 喜欢这个

这里有两种types的url。 如果url是这样的，你可以写这个函数

  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]; 

Answer 5

不是对问题的直接回答，但是如果在尝试更新contentURL后出现此错误，则在解决问题之前先调用stop（）。

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