Reply To: Embed video autoplay quix

Due to autoplay policy changes, your iframe code should be

<div id="player"></div>
<script>
  var tag = document.createElement('script');
  tag.src = "https://www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
  var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      height: '390',
      width: '640',
      videoId: 'i6qMyrm0JuA',
      events: {
        'onReady': onPlayerReady,
        'onStateChange': onPlayerStateChange
      }
    });
  }
  function onPlayerReady(event) {
    event.target.playVideo();
  }
  var done = false;
  function onPlayerStateChange(event) {
    if (event.data == YT.PlayerState.PLAYING && !done) {
    
      done = true;
    }
  }
  function stopVideo() {
    player.stopVideo();
  }
</script>

Just replace videoid with your video id
