title: Does YouTube js API has uncompressed version?
body: <p>My Windows metro app need to embed YouTube videos. Couple months ago, I embed YouTube videos in my app using  tag and YouTube Iframe/js API, the scheme is 'ms-appx-web'. It runs well. 
    But now, I find the same code that runs well before does not work any more. It's may YouTube's internal update that leads to the problem. Because the release note of YouTube API mentioned nothing.</p>
  
  <p>I want to debug YouTube API and find what happens. Where can I find the uncompressed YouTube js API? </p>
