title: URL to get the video file or stream from YouTube?
body: <p>This url returns a huge html page which is for watching the video.</p>
  
  <pre><code>http://www.youtube.com/watch?v=some_id
  </code></pre>
  
  <p>I can't go through all the HTML tags and get the right url to the actual video. I believe there is a url from where the actual video stream is coming. I expect it to be something like,</p>
  
  <pre><code>http://www.youtube.com/get_the_video?id=some_id
  Or,
  http://www.youtube.com/get_the_video/some_id.mp4
  </code></pre>
  
  <p>I can't find any information about the correct url for the video. </p>
  
  <p>Is this how YouTube maintain it's video link or their is something else? </p>
  
  <p>Do they always change the url?</p>
  
  <p>I want to do something like this in HTML to play the video.</p>
  
  <pre><code>&lt;video width="320" height="240" controls autoplay&gt;
          &lt;source src="http://www.youtube.com/get_the_video?id=some_id" type="video/mp4"&gt;
  &lt;/video&gt;
  </code></pre>
  
  <p><em>(I am new to how YouTube works. Need some guidance)</em></p>
