title: How Does VideoToolbox.framework work?
body: <p>iOS8 just released beta version, I'm very interested in Video directly Encoding / Decoding.</p>
  
  <blockquote>
    <p><strong>Video Toolbox Framework</strong></p>
    
    <p>The Video Toolbox framework (VideoToolbox.framework) includes direct
    access to hardware video encoding and decoding.</p>

  <p>but I can not find any tutorial documents for this right now</p>
  
  <p>as I know it's a private framework before, and some people already using it in some JB apps</p>
  
  <p>so does anyone can share a very simple tutorial code for this ?</p>
