title: Autoplay an embeded youtube livestream
body: <p>There are many answers on how to autoplay a regular youtube video but this doesn't work for a livestream.  I've also tried autoclicking the embedded link using something like</p>
  
  <pre><code>&lt;script&gt;
  var els = document.querySelectorAll(".ytp-large-play-button ytp-button")
  [].forEach.call(els, function (el) {el.click()});
  &lt;/script&gt;
  </code></pre>
  
  <p>but the class selector returns undefined. fyi "ytp-large-play-button ytp-button" is what I see as the class for the button when I inspect using chrome. </p>
  
  <p>As per the comment below, adding ?autoplay=true makes the embedded livestream autoplay</p>
