title: Getting vk.com embed code automatically
body: <p>I want to automatically get vk.com embed code.  I've already figured out how to get part of it</p>
  
  <pre class="lang-none prettyprint-override"><code>http://vk.com/video_ext.php?oid=3145131&amp;id=159485516&amp;hash=d821df23b7dc0b54&amp;hd=1
  </code></pre>
  
  <p>I've got the oid and id from the page source but the hash is being computed once i click on the video and what i want is that given a link like this <code>http://vk.com/video56612186</code> i want to get the embed codes of the videos in the folder.  Is this possible?</p>
