title: How to detect if Chrome/Safari/Firefox prevented autoplay for video?
body: <h2>Background</h2>
  <p>Since Chrome version 66, videos that should autoplay on my site may be prevented from playing if the user hasn't been on my site before.</p>
  <pre class="lang-html prettyprint-override"><code>&lt;video src=&quot;...&quot; autoplay&gt;&lt;/video&gt;
  </code></pre>
  <h2>Question</h2>
  <p>How do I detect if the video autoplay was disabled? And what can I do about it?</p>
