YouTube API loadVideoById startSeconds not working - iframe

Question

I created a chapter selector for some youtube videos I was embedding. This method used to work but has stopped recently. I can't figure out what's going on.
I'm using their recommended format but use loadVideoById to show each chapter
<div class="wrapper">
<div id="player"></div>
<script type="text/javascript">
var tag = document.createElement('script');
tag.src = "http://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
width: '625',
videoId: 'FE5jN0rqMtM',
events: {
'onStateChange': onPlayerStateChange
},
playerVars:{
rel: 0,
wmode: "opaque"
}
});
}
function onPlayerStateChange(evt) {
if (evt.data == 0) {
$('#video_popup').removeClass('hide_pop');
$('#video_popup').addClass('display_pop');
}
else if (evt.data == -1) {
$('#video_popup').removeClass('display_pop');
$('#video_popup').addClass('hide_pop');
}
else {
$('#video_popup').removeClass('display_pop');
$('#video_popup').addClass('hide_pop');
}
}
function chapter1() {
player.loadVideoById({'videoId': 'FE5jN0rqMtM', 'startSeconds': 0});
}
function chapter2() {
player.loadVideoById({'videoId': 'FE5jN0rqMtM', 'startSeconds': 63});
}
function chapter3() {
player.loadVideoById({'videoId': 'FE5jN0rqMtM', 'startSeconds': 135});
}
</script>
<div id="video_popup" class="hide_pop">
<div class="video_layover">
<div class="promo">Thank you for watching!<br /><br /></div>
<div class="link">Replay Video</div>
</div>
</div>
<div style="margin: 0 auto 20px auto; width:625px; height:98px; text-align:center;">
<ul class="player">
<li>Chapter 1</li>
<li>Chapter 2</li>
<li>Chapter 3</li>
</ul>
</div>

Answer 1

I'm guessing it is a bug though I wasn't able to find it documented. You could report the bug if you want.
Regardless, I think cueVideoById is a better method which is working for me in all browsers:
Example: JS Bin
function chapter2() {
player.cueVideoById('FE5jN0rqMtM', 63); // BETTER WAY
player.playVideo();
}

If you experienced an error like "TypeError: ytPlayer.loadVideoById is not a function",
then I believe you have to wait for the onReady event to fire.
Here is the sample code (part of) I use:
var ytPlayer;
var ytPlayerIsReady = false;
// this methods only works if defined in the global scope !!
window.onYouTubeIframeAPIReady = function () {
ytPlayer = new YT.Player('ytplayer', {
playerVars: {
enablejsapi: 1,
controls: 0,
fs: 1,
autoplay: 1,
rel: 0,
showinfo: 0,
modestbranding: 1
},
events: {
onReady: onReady,
onError: onError,
onStateChange: onStateChange
}
});
};
// youtube code for calling the iframe api
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
function onError(event) {
console.log("error with code" + event.data);
}
function onStateChange(event) {
console.log("change state to " + event.data);
}
function onReady(event) {
ytPlayerIsReady = true;
console.log("I'm ready");
}
window.myVideoPlayer = {
init: function (options) {
// some arbitrary code...
// the trick is to fire options.callback,
// which contains all the logic needed
function timeout() {
setTimeout(function () {
if (false === ytPlayerIsReady) {
timeout();
}
else {
if (options.callback) {
options.callback();
}
}
}, 1000);
}
timeout();
}
};
myVideoPlayer.init({
callback: function(){
// now the youtube api is ready, you should be able to call
// loadVideoById without problems (at least it worked for me)
// ytPlayer.removeEventListener('onStateChange');
// ytPlayer.addEventListener('onStateChange', '_myYtPlayerOnChange');
// ytPlayer.loadVideoById({
// videoId: 'xxxx',
// startSeconds: 12
// });
}
});

You need to make sure var player is ready before calling loadVideoById
If(player != null)
{
loadVideoById ..
}
