Disabling pause and all the visual information of an embeded youtube video.

Unfortunately I'm not sure how to handle the pause button in full screen.
But I do have a tip for advancing the question. Instead of using a timer, I would ask YT if the video has finished playing. That way in case there is a pause the video doesn't end to soon.
var qobj = this // qobj is now the qualtrics question
var element = document.getElementById("iframe1") // this is your player


function onPlayerStateChange(event) { // This function is called by the
 // event listener
// You can do more with this with other event codes
 // source for info: https://developers.google.com/youtube/iframe_api_reference?csw=1#Getting_Started
// (ctrl + f for onStateChange)
if (event.data == 0) { finished(); } // 0 means the video ended
}
function finished() {
//alert("finished") // Uncomment this to check if the finished fx is
// being called
qobj.clickNextButton(); // goes to next question after video end
}

// this will "listen" for the element to give a onStateChange event and then
// run the onPlayerStateChange fx
element.addEventListener("onStateChange",onPlayerStateChange);

Hope this helps!
