MPMoviePlayer音頻中斷問題

Question

我正在應用中的MPMoviePlayer中播放視頻，我正在從服務器中獲取視頻。 如果視頻長度約為25秒或更長，則音頻會中斷。這意味着在播放視頻時，如果達到一半，則聽不到聲音。但是，如果我搜索進度條，則會再次出現音頻。

有人可以幫我嗎？

moviePlayerController = [[MPMoviePlayerController alloc] init];
[moviePlayerController prepareToPlay];
moviePlayerController.shouldAutoplay = YES;
[moviePlayerController setScalingMode:MPMovieScalingModeAspectFit];
[[self.moviePlayerController view] setFrame:CGRectMake(0, 72, 320,180)];
[[self view] addSubview: [self.moviePlayerController view]];
self.moviePlayerController.useApplicationAudioSession = YES;

 NSString *strng = @"http://qdemo_videos.s3.amazonaws.com/1360582540.mp4";
 NSURL * adurl = [NSURL URLWithString:strng];
 moviePlayerController.contentURL = url;
 moviePlayerController.controlStyle = YES;
 self.moviePlayerController.useApplicationAudioSession = YES;
  [moviePlayerController play];

Answer 1

如果您使用Xcode 4.6或更高版本並使用iOS 6.0或更高版本，

self.moviePlayerController.useApplicationAudioSession = YES;

不會被視為不推薦使用。

就我而言，將類別設置為AVAudioSessionCategoryAmbient可以解決問題！
