我想用iPhone播放視頻，速度爲2倍

-1

我用MPMoviePlayerController播放視頻。但是沒有方法/屬性以2x速度播放視頻。我想用iPhone播放視頻，速度爲2倍

是否有任何其他方式播放視頻在2x速度？

我用這種方法播放視頻。

-(void)playMovie:(NSString *)fileName 

{ 

NSLog(@" File name :: %@",fileName); 

NSBundle *bundle = [NSBundle mainBundle]; 

NSString *moviePath = [bundle pathForResource:fileName ofType:@"mp4"]; 

NSLog(@"\n\n moviePath :: %@",moviePath); 

NSURL *url = [[NSURL fileURLWithPath:moviePath] retain]; 

moviePlayer = [[MPMoviePlayerController alloc] initWithContentURL:url]; 

moviePlayer.controlStyle = MPMovieControlStyleDefault; 

moviePlayer.shouldAutoplay = YES; 

moviePlayer.view.frame = [[UIScreen mainScreen] applicationFrame]; 

[moviePlayer.view setFrame:playVideoView.bounds]; 

[playVideoView addSubview:moviePlayer.view]; 

[moviePlayer setFullscreen:YES animated:YES]; 

}

MPMoviePlayerController符合MPMediaPlaybackprotocol，它具有以下特性：

@property(nonatomic) float currentPlaybackRate
