I created a Youtube player and added a onStateChange listener, it works for the first video.
var o = new Object;
o.videoId = 'videoid1';
player = new YT.Player('div1', o);
player.addEventListener("onStateChange", "stateChangeListener", false);
function stateChangeListener(e) {
console.log(e.data);
}
But after load a new video, onStateChange event doesn't fire anymore.
function nextVideo() {
player.cueVideoById('div2');
}
Even if I added a new listener to it.
function nextVideo() {
player.cueVideoById('div2');
player.addEventListener("onStateChange", "stateChangeListener", false);
}
What's the problem? How to fire onStateChange event if there're many videos on one page?
I think the problem is it doesn't attach the event handler to the correct Youtube player.
<iframe id="video" src="http://www.youtube.com/embed/XXXX"></iframe>
<a href="http://www.youtube.com/embed/XXXX" />

I am having a very frustrating experience trying to get videos to loop consistently using a basic iframe. I am not interacting with the API via code. I simply have an iframe with autoplay=1,mute=1,loop=1. I've tried using stand-alone videos and I've tried playlists (with list=[ID],listType=playlist) and I keep running into the same problem. Sometimes the player will loop the video and sometimes it will not. Every time I think I have it figured out and I'm ready to deploy the app, I test it again and the video fails to loop.
Windows 10
Chrome 71.0.3578.98
Angular 6.0.3
You can choose any of these options:
Check my answer where I described how you can set your URL for create a playlist (using a single videoId) and simulate a loop.
Use the YouTube iframe Player API for set your video and (once the video ended), call the playVideo() function for play the current video = hence, creating a loop.
This is the code: - unfortunately, you can't see it working here, but, you can see the working jsfiddle1
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Variables of the divs (where the YouTube iframe will load):
var player;
function onYouTubeIframeAPIReady() {
// Div player:
player = new YT.Player('player', {
height: '360',
width: '640',
videoId: 'xPCZEoGJi_4',
playerVars: {
'autoplay': 1,
'loop': 1,
'mute': 1
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
// 5. The API calls this function when the player's state changes.
function onPlayerStateChange(event) {
// When the video ends, it will play again.
// See: https://developers.google.com/youtube/iframe_api_reference?hl=en#Events
if (event.data == YT.PlayerState.ENDED) {
player.playVideo();
}
}
// Div "player" - The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.playVideo();
}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/1.8.2/jquery.min.js"></script>
<div id="player"></div>
1 If the video (once has loaded) hasn't play, you have to play manually the video - this is due some kind of restrictions that jsfiddle has.
There seems to be a lot of discussion around onStateChange event not firing but I cannot seem to find the answer my specific problem. In my case, I can connect fine with the API and load the video. The API ready event fires, followed by onPlayerReady and then onStateChange. When I closer the viewer (iFrame in which the video is embedded) and open it up again, the API ready event fires, followed by the onPlayerReady however the onStateChange does not fire when the video starts playing...
I have to refresh the browser and load the script again for the same or a different video to work which obviously in my case is not an acceptable solution.
I have also tried manually adding the listener but unfortunately I have the opposite issue with that, as multiple events are then fired as there is no way to remove that listener on closing the viewer.
I should also add that the behaviour is the same in Chrome and Firefox (latest versions)
Your help in this matter will be really appreciated.
Thanks,
Okay so I dug into the code a little bit more and minimized it to the exact problem. It's an issue with the iFrame set url call. Jeff, I modified your example on JSfiddle (http://jsfiddle.net/jeffposnick/yhWsG/3/) as follows:
HTML Code:
<div id="DIVTAG">
<iframe class="gwt-Frame" id="player" width="640" height="360" src="https://www.youtube.com/embed/M7lc1UVf-VE?wmode=transparent&enablejsapi=1&modestbranding=1&rel=0&showinfo=0&fs=0;autoplay=1"></iframe>
</div>
<button onclick="hide()">Hide Player</button>
<button onclick="show()">Show Player</button>
JavaScript Code:
var tag = document.createElement('script');
tag.src = "https://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', {
height: '390',
width: '640',
events: {
'onReady': onReady,
'onStateChange': onPlayerStateChange
}
});
}
function onReady() {
alert("player ready");
}
// The API will call this function when the video player state changes.
function onPlayerStateChange(event) {
alert("player state changed");
}
function hide() {
player.stopVideo();
document.getElementById("player").style.display="none";
}
function show() {
document.getElementById("player").style.display="block";
document.getElementById("player").src="https://www.youtube.com/embed/M7lc1UVf-VE?wmode=transparent&enablejsapi=1&modestbranding=1&rel=0&showinfo=0&fs=0;autoplay=1";
}
You can choose to ignore the "hide player" button and just click on "show player" once the video loads and you will see that the stateChange events will not fire once the player is loaded the second time.
I am simply setting the source of the iframe on which the onReady event is fired both times but the onStateChange is not. Hope this helps to suggest a fix.
That's not how you load a new video into an existing player. You should be calling player.loadVideoById('VIDEOID') instead of trying to change the src attribute of the existing iframe.
And as mentioned, please don't hide the player by setting display: none. You can move the player offscreen (negative x/y position) if needed.
We are embedding a youtube player into our page. Easy implementation of code and html5 support driven us to use the youtube iframe player.
Problem is that view count does not work with the api. No video does not autoplay and we are playing the video with youtube's default play button.
When I revert back to a AS3 player view count seems to work.
Is it a bug in the iframe api?
Anyone come across a solve?
Thanks!!!
Views that originate as a result of clicking on one of the native player UI elements (either the play button in the control bar or on the static player image) will normally count towards incrementing the views for a video. There are obviously other signals that could come into play, but all things being equal, there's no reason why using an <iframe> embed vs. an ActionScript 3 embed should prevent views from being counted.
If you have a specific example of your implementation that you want to pass along, I can take a look and see if you're doing anything unorthodox.
we have created a simple test html file with a video using the YouTube iFrame API, as the idea is to have the videoplayer fall back to the HTML5 videoplayer on mobile devices. However views are not being counted on click to play video:
http://www.youtube.com/watch?v=-LHUt9FGgys
In the body of the html we have the following:
<div id="player"></div>
<script>
var tag = document.createElement('script');
tag.src = "//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', {
height: '390',
width: '640',
videoId: '-LHUt9FGgys',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
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>
It would be interesting to see if you or someone else has a solution for this. Thanks!
Let me explain my scenario. I want to use Youtube IFrame API to embed some videos on my website.
I tested the video with id wdGZBRAwW74 (https://www.youtube.com/watch?v=wdGZBRAwW74) on this page: Youtube IFrame Player Demo. And it works OK.
I try this example code:
<!DOCTYPE html>
<html>
<body>
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
// 2. This code loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "//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: 'wdGZBRAwW74',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange,
'onError': onPlayerError
}
});
}
// 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 onPlayerError(event){
console.log(event.data);
}
function stopVideo() {
player.stopVideo();
}
</script>
</body>

with some virtual host domains on my localhost and i got result:
with domain app.centaur.com/youtube/index.htm: IFrame API work OK, the video play without problems.
with domain app.music.com/youtube/index.html: IFrame API work OK, but the video can not play, API fires onError with error 150 and the embedded player show message "This video contains content from VEVO, who has blocked it from display on this website. Watch on Youtube"
with domain app.musiccentaur.com/youtube/index.htm: like first case, everything work ok
with domain app.centaurmusic.com/youtube/: like first case, everything work ok
As i know error 150 stand for "The owner of the requested video does not allow it to be played in embedded players". But i see it still work in case 1, 3, 4, so what is it mean ?
Seem all of videos by Vevo related to this problems. I'm not sure if Vevo defined some policy for embedding their videos.
Maybe the problem come from my domain music.com, but i'm not sure there is some rules of domain to embed Vevo's video on websites.
What if i buy a domain for my website then i got error 150, this is so bad. :(
Is there anyone deal with this before? Please give me some solutions. Thanks in advance.
Note: this error only occurs on Vevo's videos.
Content owners are allowed to set up a white/black list of domain names on which embedding is allowed/denied. There is no way to work around these restriction.
This blog post has a bit more info about content restrictions in general: http://apiblog.youtube.com/2011/12/understanding-playback-restrictions.html
Currently I'm using the new iframe API to embed a YouTube video inside the uiwebview on the iPad and I've been able to make it auto play without user interactions.
In the iframe API it is described how to use the onstatechange event but in my application it doesn't seem to work and unfortunately I can't see any debug in uiwebview.
I just want to able able to detect when the video ends, have you got any advice on it?
Has anyone got it to work?
Have you tried (from the documentation) to assign an integer to the event of a movie ending?:
onStateChange This event fires whenever the player's state changes.
The data property of the event object that the API passes to your
event listener function will specify an integer that corresponds to
the new player state. Possible data values are:
-1 (unstarted)
0 (ended)
1 (playing)
2 (paused)
3 (buffering)
5 (video cued).
When the player first loads a video, it will broadcast an unstarted
(-1) event. When a video is cued and ready to play, the player will
broadcast a video cued (5) event. In your code, you can specify the
integer values or you can use one of the following namespaced
variables:
YT.PlayerState.ENDED
YT.PlayerState.PLAYING
YT.PlayerState.PAUSED
YT.PlayerState.BUFFERING
YT.PlayerState.CUED
So, something like:
if(event.data==YT.PlayerState.ENDED){
//do stuff here
}
To detect when the video ends then the video has the state of 0 or YT.PlayerState.ENDED

May this http://code.google.com/apis/youtube/js_api_reference.html#SubscribingEvents can help you
It may be connected with autoplay-policy in your browser (it's disabled by default in mobile browsers).
If your browser is chrome you can start it with additional commandline flag --autoplay-policy=no-user-gesture-required - it worked for me.
you need to make use of JavaScript for that.
