First video is loaded in 1080p than when I press a button with class="quality" It should change the quality to 720p but it's not working in HTML5 player.
It works on Flash Player but not in HTML5. I'm using JavaScript Player API.
Note: None of these solutions worked for me. YouTube iFrame API "setPlaybackQuality" or "suggestedQuality" not working
function onPlayerReady(event) {
event.target.playVideo();
event.target.setPlaybackQuality('hd1080'); //works
}
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING) {
$(".quality").click(function() {
event.target.setPlaybackQuality('hd720'); //doesn't work
});
}
}
The problem is you can not downgrade quality. Once you set to 1080p for ex you can not go back to 720p.
I have taken the example from this site YouTube Player API Reference for iframe Embeds.
I have manually added one button to change the quality which is working absolutely fine, Here is the working code.
<!DOCTYPE html>
<html>
<head>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
</head>
<body>
<button id="change_quality">Change Quality</button>
<div id="player"></div>
<script>
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',
videoId: 'M7lc1UVf-VE',
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(event) {
event.target.playVideo();
event.target.setPlaybackQuality('360p');
}
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.PLAYING) {
$("#change_quality").click(function() {
event.target.setPlaybackQuality('240p');
});
}
}
</script>
</body>
</html>
Initially onPlayerReady the quality is set to 360p.
After clicking on Change Quality button the quality is set to 144p.
Try stopping the video, then setting the playback quality, then resuming playback.
function onPlayerStateChange(event) {
$(".quality").click(function() {
event.target.stopVideo();
event.target.setPlaybackQuality('hd720');
event.target.playVideo();
});
}

I want to load a YouTube video on a button click using the Player API. The goal is that a user can input a video url, click a button, and then the video loads below (I excluded the form input below to make it a little simpler).
I've tried using location.reload(); to force reload the page, and checked out some other similar questions which aren't entirely helpful because they don't use the API (which I need to use for later when functionality added)
This example from the docs works fine:
<!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 = "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();
}
</script>
</body>
</html>
I want to get something like this (very similar version) to work. I'm not sure why it doesn't currently.
<!DOCTYPE html>
<html>
<body>
<input type="submit" value="Submit" id="submit">
<!-- 1. The <iframe> (and video player) will replace this <div> tag. -->
<div id="player"></div>
<script>
document.getElementById("submit").addEventListener("click", function() {
location.reload();
// 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();
}
});
</script>
</body>
</html>
You have two issues.
1) onYouTubeIframeAPIReady is never called because it is defined after the youtube API loads. You can see this by adding a console.log.
2) When you reload the page, the page reloads; i.e. your previous variables and video and everything are gone.
Here's a minimal example to load & play a youtube video on button click:
<input type="submit" value="Submit" id="submit">
<div id="player"></div>
<script src="https://www.youtube.com/iframe_api"></script>
<script>
document.getElementById('submit').addEventListener('click', () => {
new YT.Player('player', {
height: '390',
width: '640',
videoId: 'M7lc1UVf-VE',
events: {
onReady: e => e.target.playVideo()
}
});
});
</script>
Note, the youtube code samples are either trying to be backwards compatible or just haven't been rigorously updated. They don't follow modern styles (e.g. they use var instead of let, == instead of ===, " instead of ', etc.
I'm trying to defer the loading of YouTube CSS and JavaScript on my site for performance purposes. However, running a scan of my page with Google's Page Speed Insights indicates that the YouTube CSS file https://www.youtube.com/yts/cssbin/www-player-sprite-mode-vflixBY8E.css is not being deferred. I also tested removing the JavaScript to make sure the CSS file was not being requested by some other resource but that was not the case.
Here is the code I am using:
In my main.js file (which is deferred)
function init() {
var vidDefer = document.getElementsByClassName('youtube');
for (var i=0; i<vidDefer.length; i++) {
if(vidDefer[i].getAttribute('data-src')) {
vidDefer[i].setAttribute('src',vidDefer[i].getAttribute('data-src'));
}
}
}
window.onload = init;
Then, the iframe looks like this:
<iframe class="youtube" id="home-youtube" src="" data-src="https://www.youtube.com/embed/QHfgMrpMOm4" frameborder="0" allowfullscreen></iframe>
Thanks in advance
You could always try using Youtube's javascript API and

I am trying to change the video playing in the YouTube iframe in the cleanest way possible and a few months ago I had this code working, but YouTube changed their API and it stopped working for me. Now the onPlayerStateChange event is not firing after I switch out the video's SRC attribute to switch the video that is playing. I'm an amateur to coding so I may be missing something simple here, but any input would be greatly appreciated.
Below is a code that loads a YouTube video and when it ends, there's an alert that automatically pops up for you. However, when you click the button and switch the video by switching out the SRC attribute, the alert function stops working and its as if the entire onPlayerStateChange function stops working. I could not get it working in jsfiddle, but a link to a live demo can be found at http://thetunedrop.com/test.html

The fiddle here : http://jsfiddle.net/QtBlueWaffle/8bpQ8/1/
Hope this helps
I had kind of the same problem (I Think)... I wanted the user to be able to change the content for multiple players, and this is what works for me: I call the youtube api with a onload function additional to the new Youtubelink, so that reloads every time the iframe changes.
MY HTML:
<iframe onload="floaded1()" id="player1" width="240" height="220"
src="http://www.youtube.com/embed/0Bmhjf0rKe8
?enablejsapi=1&rel=0&showinfo=2&iv_load_policy=3&modestbranding=1"
frameborder="0" allowfullscreen> </iframe>
MY JS:
function floaded1() {
player1 = new YT.Player('player1', {
events: {
'onStateChange': function (event) {
if (event.data == 0) {
alert('done');
};
}
}
});
}
WHAT I LOAD WITH A VIDEO PICKER:
html += '<iframe onload="floaded1()" id="player1" width="240" height="220"
src="http://www.youtube.com/embed/'+YouTubeVideoId+'?enablejsapi=1&rel=0&
showinfo=2&iv_load_policy=3&modestbranding=1" frameborder="0" allowfullscreen>
</iframe>';
I have YouTube API which I got from this link...
https://developers.google.com/youtube/iframe_api_reference
It's working okay, but I am looking for a way for it to play a random video based on a tag...is this possible? Is there a tutorial on it?
Here is my code
<!-- 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 = "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: 'u1zgFlCw8Aw',
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();
}
</script>
Make Ajax function call to handle the request
function request_yt_videoID(vid)
{
// Some Code
player.loadVideoById(vid);
}
Visit Google Developer Site: https://developers.google.com/youtube/iframe_api_reference#loadVideoById
I am referring to the example code provided by Youtube seen below. The sample code is suppose to ....
The sample HTML page below creates an embedded player that will load a
video, play it for six seconds, and then stop the playback.

Can you tell why this isn't working?
