如何在xamarin iOS中使用AVPlayerViewController (AVKit)播放视频

Question

如何在xamarin iOS中使用AVPlayerLayer和AVPlayerViewControler播放视频？

playerItem = new AVPlayerItem(new NSUrl("https://clips.vorwaerts-gmbh.de/big_buck_bunny.mp4"));
        player = new AVPlayer(playerItem);
        AVcontroller.Player = player;
        AVcontroller.View.Layer.Frame = this.View.Bounds;
        this.View.AddSubview(AVcontroller.View);
        //AVcontroller.SetFullscreen(true, true);
        AVcontroller.Player.Play();

Answer 1

AVPlayer avp;
AVPlayerViewController avpvc;


var url = NSUrl.FromString(yourURL);
            avp = new AVPlayer(url);
            avpvc = new AVPlayerViewController();
            avpvc.Player = avp;
            AddChildViewController(avpvc);
            View.AddSubview(avpvc.View);
            avpvc.View.Frame = View.Frame;
            avpvc.ShowsPlaybackControls = true;
            avp.Play();

这一切都是在viewDidLoad中完成的，现在它工作得很好。

有两种播放视频的方法，选择其中一种，如代码所示：

 public override void ViewDidLoad ()
    {
        //Set the movie file path
        string moviePath = NSBundle.MainBundle.PathForResource ("loadingAnimation", "mov");
        NSUrl movieUrl = NSUrl.FromFilename (moviePath);

        //Using MPMoviePlayerController(using MediaPlayer)
        MPMoviePlayerController mpC = new MPMoviePlayerController (movieUrl);
        mpC.ControlStyle = MPMovieControlStyle.None;
        mpC.View.Frame = new CGRect (50, 50, 200, 200);
        mpC.View.BackgroundColor = UIColor.Clear;
        mpC.ShouldAutoplay = true;
        this.Add (mpC.View);
        mpC.Play ();

        //Using AVPlayer(using AVFoundation)
        AVPlayer avPlayer;
        AVPlayerLayer playerLayer;
        AVAsset asset;
        AVPlayerItem playerItem;
        asset = AVAsset.FromUrl (movieUrl);
        playerItem = new AVPlayerItem (asset);
        avPlayer = new AVPlayer (playerItem);
        playerLayer = AVPlayerLayer.FromPlayer (avPlayer);
        playerLayer.Frame = new CGRect (50, 300, 200, 200);
        View.Layer.AddSublayer (playerLayer);
        avPlayer.Play ();
    }

希望能对你有所帮助。
