how do i program the youtube embed player to unmute when clicked

Question

How do I set the youtube embedded player to unmute upon clicking it. You can see the embedded player i'm referring to at http://www.harvestarmy.org home page. It's the one at the right where it says "Latest Videos from YouTube. I set it up to be muted by default, but I want it to automatically unmute when someone clicks it.

Here is the code I used:

<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>

<script>
  // 2. This code loads the IFrame Player API code asynchronously.
  var tag = document.createElement('script');

  // This is a protocol-relative URL as described here:
  //     http://paulirish.com/2010/the-protocol-relative-url/
  // If you're testing a local page accessed via a file:/// URL, please set tag.src to
  //     "https://www.youtube.com/iframe_api" instead.
  tag.src = "//www.youtube.com/iframe_api";
  var firstScriptTag = document.getElementsByTagName('script')[0];
  firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);

  // 3. This function creates an <iframe> (and YouTube player)
  //    after the API code downloads.
  var player;
  function onYouTubeIframeAPIReady() {
    player = new YT.Player('player', {
      height: '98',
      width: '175',
      playerVars: {
        'list': 'UUFwY5Al1Doy7f0MdKnJ-gaw',
        'modestbranding': 1,
        'showinfo': 0,
        'autoplay': 1
      },
      events: {
        'onReady': onPlayerReady
      }
    });
  }

  // 4. The API will call this function when the video player is ready.
  function onPlayerReady(event) {
    event.target.mute();
  }

</script>

Thank you for that answer! I implemented it a little differently, adding it to the onYouTubeIframeAPIReady function.

I also reversed the initialized value of the isUnMuted variable. Functionally it is the same, but makes more sense this way.

var player;
var isUnMuted = false;
window.onYouTubeIframeAPIReady = function() {
    player = new YT.Player('youTube', {
        videoId: '[myVideoId]',
        playerVars: {
            'rel': 0,
        },
        events: {
            'onReady': function() {
                player.mute();
                player.playVideo();
            },
            'onStateChange': function () {
                if (player.isMuted() && player.getPlayerState() == 2 && !isUnMuted) {
                    player.unMute();
                    player.playVideo();
                    isUnMuted = true;
                }
            }
        }
    });
}

This mimics closely the behavior of embedded videos in a Facebook newsfeed.

I don't think it is possible, because there is not such thing as a 'click' or 'activate' event. However, you may try adding an event handler to the "onStateChange" event and unmute and unpause your player. I haven't tried it, but give it a try and see if this works:

var isUnMuted = true;

player.addEventListener("onStateChange", function(event) {
     if( player.isMuted() && player.getPlayerState() == 2 && isUnMuted ) {
          player.unMute();
          player.playVideo(); // resume playback
          isUnMuted = false;  // you want to run this once only! 
     }
});

This works. But unfortunately the pause icon fades in when the video is clicked. Even the video continues to run it is not a clean solution. I fixed it by placing a <div> with exactly the same size above the actual video iframe and use its click() function to unmute the video.

HTML:

  <div class="video-container">
    <div class="video-dummy">
    </div>
    <div id="player">
    </div>
  </div>

CSS:

.video-container {
  position: relative;
  width: 640px;
  height: 390px;
}

.video-dummy {
  width: 640px; 
  height: 390px;
  position: absolute;
}

Javascript:

$('.video-dummy').click(function(){
  player.unMute();
});

This works out well for me.
