title: Assigning AVAsset from NSData
body: <p>Can I initialise <code>AVAsset</code> from <code>NSData</code>.. I know i can initialise <code>AVData</code> from url using the function like</p>
  
  <pre><code> [[AVURLAsset alloc] initWithURL:url options:nil];
  </code></pre>
  
  <p>Can any one suggest me a similar way of assigning <code>AVAsset</code> directly from <code>NSData</code>?</p>
