How can I detect if YouTube videos have been removed using their iFrame API

Is it possible to detect if a video has been removed or is no longer available on Youtube using the iFrame API?
The following code will detect changes to the youtube iframe but the only data point I can find thats remotely close is -3 which means unstarted but this could be applicable to any working video as well.
CodePen
<iframe id="yt-iframe" width="630" height="354" src="http://www.youtube.com/embed/Rlm8YH2i9gY?enablejsapi=1" frameborder="0" allowfullscreen=""></iframe>
<script type="text/javascript">
var tag = document.createElement('script');
tag.id = 'yt-script';
tag.src = 'https://www.youtube.com/iframe_api';
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
console.log('yt scripts loaded');
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('yt-iframe', {
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(event) {
console.log('video player ready');
}
function onPlayerStateChange(event) {
console.log(event.data);
}
</script>

You can detect before playing the video by checking the duration of the video, if duration of the video is 0 seconds then it is highly likely to be deleted/can't be played
<iframe id="yt-iframe" width="630" height="354" src="http://www.youtube.com/embed/tPEE9ZwTmy0?enablejsapi=1" frameborder="0" allowfullscreen=""></iframe>
<script type="text/javascript">
var tag = document.createElement('script');
tag.id = 'yt-script';
tag.src = 'https://www.youtube.com/iframe_api';
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
console.log('YT scripts loaded');
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('yt-iframe', {
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(event) {
console.log('Video player ready');
if (event.target.getDuration() <= 0) {
console.log('Video likely to be removed');
}
}
function onPlayerStateChange(event) {
console.log(event.data);
}
</script>

Setup an onError event handler and check for event.data === 100. The YouTube IFrame Player API describes all of the player error events.

No, atleast not straightforward.

How to add a youtube external unmute sound

I am trying to put a button for unmute sound but having trouble executing it. My original plan was to do a toggle sound but I am looking to make the sound on work first
var tag = document.createElement('script');
tag.src = "http://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('player', {
height: '600',
width: '100%',
playerVars: { 'autoplay': 1, 'controls': 0,'autohide':1,'wmode':'opaque' },
videoId: 'W83b4HoPdFo',
events: {
'onReady': onPlayerReady}
});
}
// 4. The API will call this function when the video player is ready.
function onPlayerReady(event) {
event.target.mute();
}
$('#mutevideo').on('click', function(){
player.unmute();
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div id="player"></div>
Sound On

You can use,
player.unMute();
instead of
player.unmute();

YouTube Iframe API - Play video on mobile

After searching and finding many similar questions, I can't find the correct answer. So I'm working with the YouTube Iframe API, and I know that autoplay etc. won't work for mobiles. And I have created a element that displays on mobiles, so when the user click that button, it should play the video. But I only get this message: "Try restarting your device if playback does not start soon".
var playElement = document.createElement("div");
playElement.style.display = "none";
if( /Android|webOS|iPhone|iPad|iPod|BlackBerry|IEMobile|Opera Mini/i.test(navigator.userAgent) ) {
playElement.style.display = "block";
}
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player(child, {
width: '100%',
height: '100%',
videoId: youtubeID,
playerVars: {
'iv_load_policy': 3,
'enablejsapi': 1,
'disablekb': 1,
'autoplay': 1,
'loop': 0,
'controls': 0,
'showinfo': 0,
'rel': 0,
'mode': 'transparent'
},
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
playElement.onclick = function() {
player.playVideo();;
};
Anyone that does have an actual working solution?

Remember player refers to a div with the ID 'player'. You can start with the example code on youtube api doc. It will autoplay when the video has loaded. You can add your playerVar options as well.
A note for mobile video autoplay. You can have it autoplay but it has to be muted. So you can try adding player.mute() when you it loads and setup a click handler to unmute it again if that is what you prefer.

How do you mute an embedded Youtube player?

I'm experimenting with the Youtube player but I can't get it to mute by default.
function onPlayerReady() {
player.playVideo();
// Mute?!
player.mute();
player.setVolume(0);
}
How do I mute it from the start?
Fiddle
Update:
JavaScript Player API is deprecated.
Use iframe Embeds instead.

Turns out player.mute() works fine. It only needed the parameter enablejsapi=1. Initial test in the fiddle didn't work because the player initiation had an error. The following works.
HTML:
<iframe id="ytplayer" type="text/html" src="https://www.youtube-nocookie.com/embed/zJ7hUvU-d2Q?rel=0&enablejsapi=1&autoplay=1&controls=0&showinfo=0&loop=1&iv_load_policy=3" frameborder="0" allowfullscreen></iframe>
JS:
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('ytplayer', {
events: {
'onReady': onPlayerReady
}
});
}
function onPlayerReady(event) {
player.mute();
player.playVideo();
}
Fiddle
Credit to Gagandeep Singh and Anton King for pointing to enablejsapi=1

All above answers didn't work for me for some reason. It might be weird wordpress theme that I had to use or depreciated methods at Youtube API, I'm not sure. The only way of muting the player was to insert the code below into tag.
// Loads the IFrame Player API code asynchronously.
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/player_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Replaces the 'ytplayer' element with an <iframe> and
// YouTube player after the API code downloads.
var player;
function onYouTubePlayerAPIReady() {
player = new YT.Player('ytplayer', {
height: '390',
width: '640',
videoId: 'YOUR_VIDEO_ID',
playerVars: {
autoplay: 1,
controls: 1,
disablekb: 1,
hl: 'ru-ru',
loop: 1,
modestbranding: 1,
showinfo: 0,
autohide: 1,
color: 'white',
iv_load_policy: 3,
theme: 'light',
rel: 0
},
events: {
'onReady': onPlayerReady,
}
});
}
function onPlayerReady(event){
player.mute();
}
<div id="ytplayer"></div>

It's important to note that YouTube API mandates you run this within your markup directly within a <script> tag, or via a standard document.onLoad() native listener and not as a named function.
Otherwise it will not natively bind the onYouTubeIframeAPIReady() function to the DOM.

Try below code
var youtubeplayer = iframe.getElementById('ytplayer');
youtubeplayer .setVolume(0);
And below is your fiddle updated version,
NOTE: Must include enablejsapi=1 in video url
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('ytplayer', {
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(event) {
player.playVideo();
// Mute?!
//player.mute(); instead of this use below
event.target.mute();
//player.setVolume(0);
}

Youtube API how to play video from 0 seconds when video ends? Iframe, Javascript

So I have My code it detects when the player has stopped the problem is I can't get it to play from 0 seconds when the end has come I'm using the Iframe embed that holds a html5 video, Here is the code!
<div id="youtube-fs"><iframe id="youtube-iframe" type="text/html" src="http://www.youtube.com/embed/LYL0lzmrvk8?enablejsapi=1&html5=1&autoplay=1&showinfo=0&controls=0&rel=0&wmode=transparent&vq=hd1080&hd=1&loop=1" frameborder="0" wmode="Opaque" ></iframe> <script type="text/javascript">

function onPlayerStateChange(event) {

}
-->
</script>
</div>
Any idea's? maybe seekTo? or something
Thank you in advance!
Used player.seekTo(1, true); that worked

Try this
function onPlayerStateChange(event) {
if (event.data == YT.PlayerState.ENDED) {
player.seekTo(0);
player.playVideo();
} // Play from 0 seconds
}
