Youtube Iframe API not working in Internet Explorer (11)

Question

Since my Youtube API code did not work i´ve decided to start from the beginning and tried the example code from https://developers.google.com/youtube/iframe_api_reference?hl

Answer 1

I ran into this same issue where YouTube Player API events would not fire on IE.

I fixed it by loading the source over SSL.

Before (Worked in Chrome, FF, Safari... NOT IE 10/11)

var tag = document.createElement('script');
tag.src = "http://www.youtube.com/iframe_api";

After (Works in IE10+)

var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";

Answer 2

I was able to reproduce in http://jsfiddle.net/77PJB/3/.

function onPlayerReady(event) {
    event.target.playVideo();
}

I filed this internally. You can file it in public issue tracker if it's not filed already, to be notified once it's fixed.
