title: AVPlayerLayer not bounds to UIView frame
body: <p>I'm trying to add AVPlayerLayer to UIView</p>
  
  <pre><code>    self.player = AVPlayer(URL: NSURL(fileURLWithPath: path!))
      self.playerLayer = AVPlayerLayer(player: player);
      self.playerLayer.videoGravity = AVLayerVideoGravityResizeAspectFill;
      self.playerLayer.frame =  ctrVideo.bounds;
      self.ctrVideo.layer.addSublayer(playerLayer);
      player.play();
  </code></pre>
  
  <p>This is the video's container (in blue):</p>

  <p>Constraints:
  <a href="https://i.stack.imgur.com/TaAtK.png" rel="noreferrer"><img src="https://i.stack.imgur.com/TaAtK.png" alt="Constraints:"></a></p>
  
  <p>Final result:

  <p>I can't figure out why video is not bounds to UIVIew coordinates. If i bounds it into controller's superview, it is ok.</p>
