title: AVPlayerViewController works in iOS8 but not in IOS7
body: <p>I've been trying to get this to work for a while and i can't seem to figure out what the problem is. This code works fine on IOS8 but in IOS7 i get an error. I can see this error when i follow the debug navigator.
  In the debug area i only get an (lldb) error</p>
  
  <pre><code>Thread 1: EXC_BAD_ACCESS (code=1, address=0x10)
  </code></pre>
  
  <p>Here is my (on IOS8) working code of the videoViewController</p>
  
  <pre><code>import UIKit
  import AVKit
  import AVFoundation
  import MediaPlayer
  
  class VideoVC: UIViewController {
  override func viewDidLoad() {
      super.viewDidLoad()
  
      var url:NSURL = NSURL(string: "http://jplayer.org/video/m4v/Big_Buck_Bunny_Trailer.m4v")!
      let player = AVPlayer(URL: url)
      let playerController = AVPlayerViewController()
  
      playerController.player = player
      self.addChildViewController(playerController)
      self.view.addSubview(playerController.view)
      playerController.view.frame = self.view.frame
  
      player.play()
  }
  
  override func didReceiveMemoryWarning() {
      super.didReceiveMemoryWarning()
      // Dispose of any resources that can be recreated.
  }
  }
  </code></pre>
