Hi I am trying to stream a video on my iphone app. The code plays a local file but crashes with an error " Terminating app due to uncaught exception 'NSInvalidArgumentException', reason: 'An AVPlayerItem cannot be associated with more than one instance of AVPlayer'" when used to stream a video from a server. Also the link streams the video absolutely fine in a browser but however i am not able to play the video in the app. Please Help . Thanks

推荐答案

如果出现同样的问题，请在设置SourceType之后尝试设置ContentURL，如下所示

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

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