title: Cocoa: AVAsset from raw data (i.e. NSData)
body: <p>I'd like to use <strong>AVFoundation</strong> to display a video on osx. I would like to initialize the movie from raw data at runtime. According to this document: <a href="https://developer.apple.com/library/mac/#technotes/tn2300/_index.html">https://developer.apple.com/library/mac/#technotes/tn2300/_index.html</a> <code>AVAsset</code> is the equivalent of <strong>QTKit's</strong> <code>QTMovie</code>. <code>QTMovie</code> has the function <code>movieWithData:error:</code> to load  the video from data, while i could not find anything similar in <code>AVAsset</code>. So, is it possible to do the same thing in <strong>AVFoundation</strong> at all?</p>
  
  <p>Thank you</p>
