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.

- @UnLoCo that relates to the video itself, what I seek is in no way dependent on the video but rather on the embedded player. – Mikulas Dite Commented Aug 17, 2012 at 22:59
- Seems it is not possible with conventional means. Could it be done via checking dom of html5 player? The captions should be there, right? – Mikulas Dite Commented Aug 19, 2012 at 18:20
- @MikulasDite HTML5 player will be embedded in an iframe, so you won't be able to access its content [same origin policy] – Hrant Khachatrian Commented Aug 22, 2012 at 12:21
- @MikulasDite: You would have to use postMessage to municate with the iframe of the HTML5 player (direct access won't be possible due to same-origin policy), the API exposed there is the same as for the Flash player. – Wladimir Palant Commented Aug 27, 2012 at 9:24

Reset to default 6I have not found this anywhere in their api docs, but with your youtube player object you should be able to do:
player.getOptions("captions") || player.getOptions("cc") //detects if captions were ever loaded at one point.
You can also turn it on via js by:
player.loadModule("captions"); //Works for html5 ignored by AS3
player.loadModule("cc"); //Works for AS3 ignored by html5
to turn it off:
player.unloadModule("captions"); //Works for html5 ignored by AS3
player.unloadModule("cc"); //Works for AS3 ignored by html5
to change which language if the module is loaded:
player.setOption("captions", "track", {"languageCode": "es"}); //Works for html5 ignored by AS3
player.setOption("cc", "track", {"languageCode": "es"}); //Works for AS3 ignored by html5
Easy as pie, you can ;)

You need Flash player 8+ and JavaScript enabled to view this video.

<script type="text/javascript">
var params = { allowScriptAccess: "always" };
var atts = { id: "myytplayer" };
swfobject.embedSWF("http://www.youtube./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>

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 ;)
