JavaScript to control play/pause embedded YouTube videos

I need to embed multiple YouTube videos on a website. For each video, I need to set up an external element (such as a paragraph, image, div, etc) that can trigger the YouTube video to play, and a separate element that will trigger the YouTube video to pause.
I have some Javascript code that I can use to play/pause one embedded YouTube video. However, if I attempt to create play/pause buttons for more than one YouTube video on the same page, only the buttons for the last YouTube video will work.
To demonstrate the issue, I created two JS Fiddles. The first Fiddle shows how it works when there is only one YouTube video on the page.
The second Fiddle shows what happens when I try to create buttons for more than one YouTube video on the same page. As you'll see, only the buttons for the last YouTube video work.
Any suggestions would be greatly appreciated. I've included the JS Fiddle links (and the accompanying code) below. Thank you!

YouTube video autoplay on mobile [duplicate]

To my problem, I have one link . I want to play the video by clicking the link in a fancybox overlay window. This is not a problem. The problem is the parameters, for example "autoplay" or "autohide".
The following link doesn't work:
The Overlay-Window opened, but the video is not playing automatically.
EDIT: I want to use the HTML5 Player on mobile devices. On a desktop-browser it works with the parameters, but not on mobile devices.

As it turns out, autoplay cannot be done on iOS devices (iPhone, iPad, iPod touch) and Android.
See https://stackoverflow.com/a/8142187/2054512 and https://stackoverflow.com/a/3056220/2054512

Have a look on code below.
Tested and found working on Mobile and Tablet devices.
<!-- 1. The <iframe> (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>

The code below was tested on iPhone, iPad (iOS13), Safari (Catalina). It was able to autoplay the YouTube video on all devices. Make sure the video is muted and the playsinline parameter is on. Those are the magic parameters that make it work.

The official statement "Due to this restriction, functions and parameters such as autoplay, playVideo(), loadVideoById() won't work in all mobile environments.
Reference: https://developers.google.com/youtube/iframe_api_reference

There is a way to make youtube autoplay, and complete playlists play through. Get Adblock browser for Android, and then go to the youtube website, and and configure it for the desktop version of the page, close Adblock browser out, and then reopen, and you will have the desktop version, where autoplay will work.
Using the desktop version will also mean that AdBlock will work. The mobile version invokes the standalone YouTube player, which is why you want the desktop version of the page, so that autoplay will work, and so ad blocking will work.

How to use a Youtube channel live url to embed and autoplay. Instead of Video ID that has to be constantly updated for live stream changes.
I mixed two sets of code and came up with a working auto play Youtube video embed from a channel live stream.
My thanks to both of the other contributors for their help. Hopefully this helps someone else some time.

YouTube IFrame API with existing IFrame failing to run callbacks

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.

how do i program the youtube embed player to unmute when clicked

How do I set the youtube embedded player to unmute upon clicking it. You can see the embedded player i'm referring to at http://www.harvestarmy.org home page. It's the one at the right where it says "Latest Videos from YouTube. I set it up to be muted by default, but I want it to automatically unmute when someone clicks it.
Here is the code I used:
<!-- 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');
// This is a protocol-relative URL as described here:
// http://paulirish.com/2010/the-protocol-relative-url/
// If you're testing a local page accessed via a file:/// URL, please set tag.src to
// "https://www.youtube.com/iframe_api" instead.
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: '98',
width: '175',
playerVars: {
'list': 'UUFwY5Al1Doy7f0MdKnJ-gaw',
'modestbranding': 1,
'showinfo': 0,
'autoplay': 1
},
events: {
'onReady': onPlayerReady
}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.mute();
}
</script>

Thank you for that answer! I implemented it a little differently, adding it to the onYouTubeIframeAPIReady function.
I also reversed the initialized value of the isUnMuted variable. Functionally it is the same, but makes more sense this way.
var player;
var isUnMuted = false;
window.onYouTubeIframeAPIReady = function() {
player = new YT.Player('youTube', {
videoId: '[myVideoId]',
playerVars: {
'rel': 0,
},
events: {
'onReady': function() {
player.mute();
player.playVideo();
},
'onStateChange': function () {
if (player.isMuted() && player.getPlayerState() == 2 && !isUnMuted) {
player.unMute();
player.playVideo();
isUnMuted = true;
}
}
}
});
}
This mimics closely the behavior of embedded videos in a Facebook newsfeed.

I don't think it is possible, because there is not such thing as a 'click' or 'activate' event. However, you may try adding an event handler to the "onStateChange" event and unmute and unpause your player. I haven't tried it, but give it a try and see if this works:
var isUnMuted = true;
player.addEventListener("onStateChange", function(event) {
if( player.isMuted() && player.getPlayerState() == 2 && isUnMuted ) {
player.unMute();
player.playVideo(); // resume playback
isUnMuted = false; // you want to run this once only!
}
});

This works. But unfortunately the pause icon fades in when the video is clicked. Even the video continues to run it is not a clean solution.
I fixed it by placing a <div> with exactly the same size above the actual video iframe and use its click() function to unmute the video.
HTML:
<div class="video-container">
<div class="video-dummy">
</div>
<div id="player">
</div>
</div>
CSS:
.video-container {
position: relative;
width: 640px;
height: 390px;
}
.video-dummy {
width: 640px;
height: 390px;
position: absolute;
}
Javascript:
$('.video-dummy').click(function(){
player.unMute();
});
This works out well for me.
