title: How to get source url of youtube video?
body: <p>I am trying to get youtube url from this code ...</p>
  
  <pre><code>&lt;div class="html5-video-container" data-layer="0"&gt;
      &lt;video tabindex="-1" class="video-stream html5-main-video" controlslist="nodownload" src="blob:https://www.youtube.com/654261e0-472e-42b8-baac-951c85f8bb18" style="width: 514px; height: 289px; left: 0px; top: 0px;"&gt;&lt;/video&gt;
  &lt;/div&gt;
  </code></pre>
  
  <p>I can get src from this blob:<a href="https://www.youtube.com/654261e0-472e-42b8-baac-951c85f8bb18" rel="nofollow noreferrer">https://www.youtube.com/654261e0-472e-42b8-baac-951c85f8bb18</a>. But i cant render video by this url. The question is how to get reference link to video source ? Or maybe exist youtube API to get source of video ?</p>
