Is it possible to detect whether youtube captions are on or off in an embedded player?

There is currently no way to suppress the captions if users choses to display them. I would like to show a customized message if the captions are on.

In the documentation there is no mention of this as far as I can say.

    Easy as pie, you can 😉

    <!DOCTYPE html>
<html>
<head>
<title>test</title>
</head>
<body>
<script src="//ajax.googleapis.com/ajax/libs/swfobject/2.2/swfobject.js"></script>
  <div id="ytapiplayer">
    You need Flash player 8+ and JavaScript enabled to view this video.
  </div>

  <script type="text/javascript">

    var params = { allowScriptAccess: "always" };
    var atts = { id: "myytplayer" };
    swfobject.embedSWF("http://www.youtube.com/v/QRS8MkLhQmM?enablejsapi=1&playerapiid=ytplayer&version=3",
                       "ytapiplayer", "640", "480", "8", null, null, params, atts);

    var stateChange = function(a) {
            if (ytplayer.getOptions().indexOf("cc") !== -1) {
        alert("closed captions are on");
      } else {
        alert("closed captions are off");
      }
    }
   function onYouTubePlayerReady(playerId) {
      ytplayer = document.getElementById("myytplayer");
      ytplayer.addEventListener("onStateChange","stateChange");
    }
  </script></body>
</html>

    BTW: Google rocks 😉

    this should do the trick – please don’t use it in production mode – it was just a quick sum-up. You need to listen to the state you want, I’m just alerting at any event 😉
