title: Youtube caching on Chrome app
body: <p>Does anyone knows a solution to cache YouTube videos on a chrome app ?</p>
  
  <p>I know there are ways to write data and access it later, but i can't find a way to do it with Youtube.
  I'm aiming at be able to display those videos Offline or just to consume a small amount of bandwidth.</p>
  
  <p>Thanks in advance.</p>
