Ios MPMovieplayercontroller缓冲区状态和流时暂停

我正在制作一个视频播放应用程序，在我的服务器上播放视频。我通过以下代码启动应用程序

    var url:NSURL = NSURL(string: "http://download1.mp4mobilemovies.net/Bollywood/Baahubali%20-%20The%20Beginning%20-%20DvdScr/Baahubali%20-%20The%20Beginning%20-%20DvdScr%20-%201.mp4")!

    self.moviePlayer = MPMoviePlayerController()
    moviePlayer.movieSourceType = MPMovieSourceType.Streaming
    self.moviePlayer = MPMoviePlayerController(contentURL: url)
    self.moviePlayer.prepareToPlay()
    self.moviePlayer.shouldAutoplay = true
    self.moviePlayer.stop()
    self.moviePlayer.view.frame = self.view.frame
    self.view.addSubview(self.moviePlayer.view)
    self.moviePlayer.fullscreen = true
    self.moviePlayer.setFullscreen(true, animated: true)
    self.moviePlayer.controlStyle = MPMovieControlStyle.Embedded
    self.moviePlayer.scalingMode = MPMovieScalingMode.AspectFit
    self.moviePlayer.play()

甚至我有一个HUD，当视图出现时，它开始显示进度指示器，在那里我还设置了两个通知对象，以查看视频的playbackstate更改以及电影的加载状态。播放状态更改工作正常。视频开始播放，一段时间后进入暂停状态，加载状态不会变为暂停或未知，这样我就知道这是缓冲状态。请告知如何处理缓冲区状态和缓冲区完成时的自动播放

 NSNotificationCenter.defaultCenter().addObserver(self, selector: "videoCanPlay:", name: MPMoviePlayerLoadStateDidChangeNotification, object: nil)
 NSNotificationCenter.defaultCenter().addObserver(self, selector: "playbackchanged:", name:MPMoviePlayerPlaybackStateDidChangeNotification, object: nil)

func videoCanPlay(notification: NSNotification){
    var moviePlayerController = notification.object
        as! MPMoviePlayerController
    if(self.moviePlayer?.loadState == MPMovieLoadState.Playable)
    {
       // let value = UIInterfaceOrientation.LandscapeLeft.rawValue
       // UIDevice.currentDevice().setValue(value, forKey: "orientation")
      //  NSLog("Play");
        MBProgressHUD.hideAllHUDsForView(self.view, animated: true)
    }

///这些状态不会被调用

    if(self.moviePlayer?.loadState == MPMovieLoadState.Stalled)
    {
        NSLog("stalled");
    }

     if (self.moviePlayer?.loadState == MPMovieLoadState.Unknown)
    {
        NSLog("unknown");
    }

}

您可以使用此方法检查播放机是否正在缓冲：

self.moviePlayer?.playableDuration

我没有测试答案，但我认为如果playableDuration为0，那么玩家当前正在缓冲
