播放内存使用最少的视频

Question

使用MPMoviePlayerController在我的捆绑中播放视频文件，并使用重复模式MPMovieRepeatModeOne。在视频播放时间内，在运行时需要50mb的大内存。请帮我解决这个问题。哪个是一个非常大的问题。一旦视频播放器被删除，消耗的内存就会消失

NSString *filepath   =   [[NSBundle mainBundle] pathForResource:@"ConnectorAnimation.mp4" ofType:nil];
    NSURL    *fileURL    =   [NSURL fileURLWithPath:filepath];
    mediaPlayer = [[MPMoviePlayerController alloc] initWithContentURL:fileURL];
    mediaPlayer.fullscreen = YES;
    mediaPlayer.repeatMode = MPMovieRepeatModeOne;
    mediaPlayer.controlStyle = MPMovieControlStyleNone;
    [_contentView addSubview:mediaPlayer.view];
    CGRect frame = _contentView.bounds;
    mediaPlayer.view.frame = frame;

    mediaPlayer.view.autoresizingMask = UIViewAutoresizingFlexibleWidth | UIViewAutoresizingFlexibleHeight | UIViewAutoresizingFlexibleTopMargin | UIViewAutoresizingFlexibleLeftMargin | UIViewAutoresizingFlexibleRightMargin | UIViewAutoresizingFlexibleBottomMargin;
    [mediaPlayer play];
