MPMoviePlayerController显示黑屏 [英] MPMoviePlayerController showing black empty screen

问题描述

我使用MPMoviePlayerController播放我已经下载了服务器URL的Application Document文件夹中的本地文件:

I use MPMoviePlayerController to play a local file in my Application Document folder which have I have downloaded for a server URL:

itemMoviePlayerController = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
 [self.view addSubview:itemMoviePlayerController.view];
 itemMoviePlayerController.fullscreen = YES;
 itemMoviePlayerController.movieSourceType = MPMovieSourceTypeFile;
 itemMoviePlayerController.initialPlaybackTime = -1.0;
 [itemMoviePlayerController play];

下载文件后立即播放.mov文件时，它会显示黑屏和空白.应用程序用户界面不可用. 但是，如果下次播放相同的本地文件，则可以正常播放. 我什至验证了playState& localState对于MPMoviePlayerController，它们似乎不错. 黑屏的原因可能是什么?

When I play .mov file just after I downloaded it, It shows up a black empty screen & app UI is unusable. But if play same local file next time, it plays fine. I even verified playState & localState for MPMoviePlayerController they seems fine. What could be reason for black empty screen?
