Fire an event on play of youtube iframe embed

• DEMO: https://so.lucafilosofi.com/fire-an-event-on-play-of-youtube-iframe-embed/

<script src="https://www.youtube.com/iframe_api"></script>

<div class="module module-home-video">
    <span class="module-strip">Latest Product Video</span>
    <div id="video"></div>
</div>

<script>
    var player, playing = false;
    function onYouTubeIframeAPIReady() {
        player = new YT.Player('video', {
            height: '360',
            width: '640',
            videoId: 'RWeFOe2Cs4k',
            events: {
                'onStateChange': onPlayerStateChange
            }
        });
    }

    function onPlayerStateChange(event) {

      if (event.data == YT.PlayerState.PLAYING) {
         alert('video started');
         playing = true;
        }

      else if(event.data == YT.PlayerState.PAUSED){
            alert('video paused');
            playing = false;
       }
}
</script>

You should be able to use the youtube javascript api, doing something like this:

var ytplayer = null;

// event that will be fired when the player is fully loaded
function onYouTubePlayerReady(pid) {
   ytplayer = document.getElementById("ytplayer");
   ytplayer.addEventListener("onStateChange", "onPlayerStateChange");
}

// event that will be fired when the state of the player changes
function onPlayerStateChange(state) {
  // check if it's playing
  if(state == 1) {
    // is playing
  }
}

To load your video in a embedded player you would use the following url:

http://www.youtube.com/v/RWeFOe2Cs4k?version=3&enablejsapi=1

I also think you should be able to add the iframe directly like this:

<iframe id="ytplayer" type="text/html" width="640" height="360" 
 src="https://www.youtube.com/embed/RWeFOe2Cs4k?enablejsapi=1"
 frameborder="0" allowfullscreen>
