   asset = AVAsset.FromUrl (NSUrl.FromFilename ("sample.m4v"));
   playerItem = new AVPlayerItem (asset);
   

6. Create an AVPlayer and pass it the AVPlayerItem created above.

   player = new AVPlayer (playerItem);
   

7. Create an AVPlayerLayer from the AVPlayer instance and add as a sublayer to the view’s layer.

   playerLayer = AVPlayerLayer.FromPlayer (player);
   playerLayer.Frame = View.Frame;
   View.Layer.AddSublayer (playerLayer);
