title: Direct link of Youtube video
body: <p>I would like to get from the link <a href="http://www.youtube.com/watch?v=GzmpH7eaA4k" rel="noreferrer">http://www.youtube.com/watch?v=GzmpH7eaA4k</a> the direct link of the video, something like: <a href="http://www.youtube.com/(...).mp4" rel="noreferrer">http://www.youtube.com/(...).mp4</a></p>
  
  <p>Is it possible? I have seen a lot of threads that use "www.youtube.com/get_video_info" and other ways but I think that all of them are obsolete right now.</p>
  
  <p>How can I get the URL that I need?</p>
