I have a YouTube player that sits in a slide of a Bootstrap carousel that sits in a template (the below doesn't include the html for the carousel):
<script type="text/html> <div class="video-container" id="introVideoTmpl">
 <iframe width="640" height="480" src="//www.youtube.com/embed/Kn-7OlEVdNM?rel=0&enablejsapi=1" id="videoOne" frameborder="0" allowfullscreen></iframe>
</script>
I render this by making a JavaScript call:
renderPageOne = function(){
var introVideoTmpl= $("#introVideoTmpl").html();
$("#container").empty();
$("#container").append(_.template(introVideoTmpl, ""));
getPlayerOne();
getPlayerOne() generates an instance of the player:
function getPlayerOne() {
    playerOne = new YT.Player('videoOne', {});
}
This playerOne has a pauseVideo() method which I call when needed.
It works fine most of the times but sometimes, with low bandwith the API seems not to load properly and the pauseVideo() does not work.
How can I check that the API is loaded properly so that the video can be paused when necessary?
