I have this script as described here: YouTube Player API:
<!DOCTYPE html>
<html>
<!-- ... -->
<body>
<h1>Youtube Video</h1>
<div id="player"></div>
<script type="text/javascript">
// Load the IFrame Player API code asyncronously
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Creating an iframe and youtube player
var player;
function onYoutubeIframeAPIReady(){
console.log("Youtube API Loaded");
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'LSwbPyIP-gY',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// When video_player is ready, call this function
function onPlayerReady(event){
event.target.playVideo();
}
var done = false;
function onPlayerStateChange(event){
if (event.data == YT.PlayerState.PLAYING && !done){
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo(){
player.stopVideo();
}
</script>
</body>
</html>
After reloading the page, nothing happing. So, at the end of the script, I call this function:
onYoutubeIframeAPIReady();
Doing this, gives me an error:
(index):25 Uncaught ReferenceError: YT is not defined
But when I check the generated source code, I see this two lines before my script tag:
<script type="text/javascript" id="www-widgetapi-script" src="https://s.ytimg.com/yts/jsbin/www-widgetapi-vflWkc-3E/www-widgetapi.js" async=""></script>
<script src="https://www.youtube.com/iframe_api"></script>
If the IFrame Player API code are being loaded, why I am getting the error "YT is not defined" ? What am I missing?
To run this test, I am using Google Chrome 51.0.2704.79 (64-bit)
You don't have to call onYoutubeIframeAPIReady by yourself.
Youtube server side code call it for you.
Check in their code you will find this code:
var Sb = l("onYTReady");
Sb && Sb();
var Tb = l("onYouTubeIframeAPIReady");
Tb && Tb();
var Ub = l("onYouTubePlayerAPIReady");
Ub && Ub();
You just load the script and it call your function.

I am using youtube embed to display a video. I need to autoplay when site is opened
<iframe class="slider-image-mockup align-center" width="100%" height="750" src="https://www.youtube-nocookie.com/embed/Y-p828Jy8C8?rel=0&controls=0&autoplay=1&loop=1&playlist=Y-p828Jy8C8&showinfo=0" frameborder="0" allow="autoplay; loop; encrypted-media" allowfullscreen></iframe>
I am using this code before it was working fine but for past few days. Autoplay is not working...
It may sound crazy but I didn't change anything in my code.
its showing like below after clicking of play button only video is playing
<!DOCTYPE html>
<html>
<body>
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->

var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)

var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {

}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),

var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>
</body>
</html>
now I have changed the url
from : https://www.youtube-nocookie.com/embed/Y-p828Jy8C8?rel=0&controls=0&autoplay=1&loop=1&playlist=Y-p828Jy8C8&showinfo=0
To : https://www.youtube.com/embed/Y-p828Jy8C8?rel=0&controls=0&showinfo=0&autoplay=1&loop=1&playlist=Y-p828Jy8C8
now its working... Thank you..
Somewhat related to:
YouTube IFrame API doesn't always load?
But different in that I AM loading the YouTube script per instructions. Note, in my source, the iframe is ABOVE the script block in the load order. I based this off of these instructions (below). The example works fine if I'm on that page, but doesn't seem to work for me when I put the code on mine. I'm sure I'm missing something really simple but I'm to be missing it. Thanks!

Best way to load a Youtube Video by his API, is following this sintaxis:
<div id="video-youtube"></div>
<script id="youtube-tracking-script">
var youtubeVideoId = 'u3A7bmEOtaU'; // replace with your own video id
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementById("youtube-tracking-script");
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var video;
function onYouTubeIframeAPIReady() {
video = new YT.Player('video-youtube', {
height: '352',
width: '100%',
videoId: youtubeVideoId,
playerVars: {rel: 0, showinfo: 0},
events: {
'onStateChange': videoPlay
}
});
}
function videoPlay(event) {
if (event.data == YT.PlayerState.PLAYING) {
console.log("YouTube Video is PLAYING!!");
}
if (event.data == YT.PlayerState.PAUSED) {
console.log("YouTube Video is PAUSED!!");
}
if (event.data == YT.PlayerState.ENDED) {
console.log("YouTube Video is ENDING!!");
}
}
</script>

You should replace your <iframe> </iframe> to <div id= "js_youTubeFrame"> </div>, in my case it works.
I think that Youtube Iframe Api needs that div to convert it on iframe after.
I am trying to implement the example youtube api html page described here: https://developers.google.com/youtube/iframe_api_reference in a meteor application.
I have read that you can use Template.<template name>.rendered to implement traditional javascript functionality within a meteor application.
So I attempted to implement that youtube example in meteor by putting it into a rendered function.
However No video will display.
I worry I am not understanding meteors capabilities. Is something like this even possible in meteor?
Code:
home.html:
enter code here
<template name="home">
<h1> Home</h1>
This is the home page
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
</script>
</template>
home.js:
Template.home.rendered = function() {
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// 3. This function creates an <iframe> (and YouTube player)
// after the API code downloads.
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
// 5. The API calls this function when the player's state changes.
// The function indicates that when playing a video (state=1),
// the player should play for six seconds and then stop.
var done = false;
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
}
P.s. I am aware of adrianliaw:youtube-iframe-api and do not want to use that. I would like a better understanding of how to implement this on my own. Hopefully doing so will further my knowledge of javascript and meteor.
I think the problem here is that after https://www.youtube.com/iframe_api loads, it will try to call the onYouTubeIframeAPIReady function but it can't find it. The code works if you change the functions to anonymous functions stored in variables that are available across the entire application.
home.html:
<head>
<title>test</title>
</head>
<body>
{{> home}}
</body>
<template name="home">
<h1> Home</h1>
This is the home page
<div id="player"></div>
</template>
home.js:
Template.home.rendered = function() {
/* 2. This code loads the IFrame Player API code asynchronously. */
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
/* 3. This function creates an <iframe> (and YouTube player) */
/* after the API code downloads. */
var player;
onYouTubeIframeAPIReady = function() {
player = new YT.Player('player', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
};
/* 4. The API will call this function when the video player is ready. */
onPlayerReady = function(event) {
event.target.playVideo();
};
/* 5. The API calls this function when the player's state changes. */
/* The function indicates that when playing a video (state=1), */
/* the player should play for six seconds and then stop. */
var done = false;
onPlayerStateChange = function(event) {
if (event.data == YT.PlayerState.PLAYING && !done) {
setTimeout(stopVideo, 6000);
done = true;
}
};
stopVideo = function() {
player.stopVideo();
};
};
Notice the function declaration changes:
function onYouTubeIframeAPIReady() has been changed to
onYouTubeIframeAPIReady = function()
function onPlayerReady(event) has been changed to onPlayerReady
= function(event)
function onPlayerStateChange(event) has been changed to
onPlayerStateChange = function(event)
function stopVideo() has been changed to stopVideo = function()
These global variables are now callable by the injected YouTube script.
So from what I can gather one or two things are going from with my youtube video's either the seekTo function has stopped working or the hole API has....(Or youtube has changed something) Now please take in mind my codes were working flawlessly without fault untill yesterday... (code usually doesn't break over night).
Here are 2 sites with the SeekTo function that loops the video via PlayerState ENDED:
http://imvu.url.ph/aattpx/DC_MAR/Base/XML/COMPIC_X1/2014/LayDStroke/maintemp/index.html
http://imvu.url.ph/FTP/2013/System/Core/Int/Warning/Dont_Not_Touch/DKLAY2013BLUE/Layout/Infuriate/index.html
The codes for the youtube video are more or less identical so I'll just post 1 of the codes:
view-source:imvu.url.ph/aattpx/DC_MAR/Base/XML/COMPIC_X1/2014/LayDStroke/maintemp/video.html

I have used the code refering https://developers.google.com/youtube/iframe_api_reference#Getting_Started. I have copied the same code as provided in above url. But, it gives me a blank page.

setTimeout(stopVideo, 6000);
done = true;
}
}
function stopVideo() {
player.stopVideo();
}
</script>
Can anyone please help me to resolve this issue?
This code seems good. What did you paste it in? Maybe it's an unrelated syntax error...
