**  To play the visual component of an asset, you need a view 

**  containing an AVPlayerLayer layer to which the output of an 

**  AVPlayer object can be directed. You can create a simple 

**  subclass of UIView to accommodate this. Use the view’s Core 

**  Animation layer (see the 'layer' property) for rendering.  

**  This class, AVPlayerDemoPlaybackView, is a subclass of UIView  

**  that is used for this purpose.
