This is very weird. I'm using youtube JavaScript API to embed a playlist on my website. It would be all good except my recent check what's happening in my workers. It seems that the API decided to send it's messages to one of it.
here's the data which my worker is receiving.
bubbles: falsecancelBubble: falsecancelable: falsecurrentTarget: Windowdata: "{"event":"infoDelivery","info":{"currentTime":109.455757,"videoBytesLoaded":1,"videoLoadedFraction":1},"id":1}"defaultPrevented: falseeventPhase: 0lastEventId: ""origin: "https://www.youtube.com"path: Array[1]ports: Array[0]returnValue: truesource: WindowsrcElement: Windowtarget: WindowtimeStamp: 1428083437641type: "message"__proto__: MessageEvent
Also as I've seen in another question Youtube API does this
www-embed-player.js:167 GET chrome-extension://enhhojjnijigcajfphajepfemndkmdlo/cast_sender.js net::ERR_FAILED
I wasn't expecting Google to create such faulty API. Is there a way to disable those things?
Quick experiment rendered a solution. Moved all youtube code to a separate html and embedded in my parent page.
<iframe id="youtubePlayer" src="mediaPlayer.html">
You can still access youtube api from your main page like that
var mediaPlater = document.getElementById('youtubeFrame').contentWindow.player;
// i.e. skip to next video
mediaPlayer.nextVideo();
This solved totally unexpected worker activity. This console error remained but after reading that it's a won't-fix it doesn't bother me.
www-embed-player.js:167 GET chrome-extension://
Content of my mediaPlayer.html
<div id="ytplayer" class="musicPlayer"></div>

OK... been working on this for a couple of months with no working results as of yet... So, now asking for help! I have a YouTube playlist, ID: PLl_KM23gznEAZW-INW8ty4QNaHH8JCnNW. This playlist has close to 1500 videos on it. I am needing a code that will call the list, and play a random video from the list. and I need it to play all 1500 videos in a random order without repeating any of the videos. then after the playlist is completed, it needs to start over, continuing to play the videos in a completely different random order.
I have tried several code snippets and can't seem to get it all to come together. I either get a shuffle with repeats, or I get just a list that doesn't play anything, or it will randomly pick the first video, then maybe the second one, but it will start playing in order from either the first or the second video. And the current youtube player that is working will only call the videos in a 200 song list. IE: if the payer starts in order, only will play 1 through 200, then stop. Or, I can set it to start with any song in the playlist, for instance, # 999, it will go to that video, but will only play videos fromm 999 to 1198.
I have to randomly pick the song and put it in my code to get it to do that.
I need it to start in shuffle mode, choosing any song from the list of 1500 videos, then continue randomly choosing and playing any other video within the list except those that have already played, until it has played all the videos, then loop the playlist and continuing to play a random video from the playlist in no certain order, including the order it just played. My main thing to avoid... having to create the list array manually. I need to be able to call the url of the playlist, and retrieve a list of the videos either by number, video ID, name of the song, etc. Using the easiest, cleanest code.
PS: having comments in place is extremely helpful for my learning process.
And please don't worry about anything, I am 51, disabled, and trying to remind myself of the coding syntaxes after getting a degree in 2003 and not using a bit of it since! I am working on a project for myself, more or less trying to get myself back into being able to read, repair, and create coding for myself. This part though, has me totally stumped!
I hope this is making sense to someone, I'm getting confused just trying to ask the question!!!
tried this one, got nothing... just a blank page...
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
function onYouTubeIframeAPIReady() {
var player = new YT.Player("player", {

event.target.playVideo();
setTimeout(function() {
event.target.setShuffle({'shufflePlaylist' : true});
}, 1000);
}
}
});
}
this one will load the player, but doesn't shuffle or play randomly. just starts with the first video, then continues in order...

tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];

function onPlayerReady(event) {

}
this one will start with a random video, but then continues in order from there...

function getRandomId() {
var random_id = 0
while(played_idx.indexOf(random_id) != -1) {

I'm pretty sure there were more, but can't find them at the moment.
We have a number of clients who have youtube video advertisements. These are currently in a YouTube playlist, but by embedding the playlist, the same video is always displayed first on the website so we want to randomise which video is displayed on pageload from the playlist. I have a code snippet which will load a random video from the input video url however when the video is finished it does not move on to the next video in the list. Could anyone suggest how I can accomplish what I am trying to do? My code is below.
<!-- Youtube video loop playlist -->
<script>
var videos = ["https://www.youtube.com/embed/9bZkp7q19f0", "https://www.youtube.com/embed/dQw4w9WgXcQ", "https://www.youtube.com/embed/CzJ-h7W1hVw"];
window.onload = function () {
var playerDiv = document.getElementById("random_player");
var player = document.createElement("IFRAME");
var randomVideoUrl = videos[Math.floor(Math.random() * videos.length)];
player.setAttribute('width', '528');
player.setAttribute('height', '330');
player.setAttribute('src', randomVideoUrl);
playerDiv.appendChild(player);
};
onStateChange: function(e){
var id = 'qzZuBWMnS08';
if(e.data === YT.PlayerState.ENDED){
player.loadVideoById(videos);
}
}
</script>
<div id="random_player"></div>
Thank you in advance.
Donna
The function loadVideoById can either get a single ID or a single video in an object syntax. It can't receive an array of videos or a playlist.
Here's my implementation
http://jsfiddle.net/thatkookooguy/e11oy0eu/2247/
(code also embedded at the end)
Notice that the setTimeout is used since there's a bug with the youtube API. if you set either setShuffle or playVideoAt immediately, nothing happens (or the playlist resets and starts from the beginning).
You can add anything else you want to change in the player's playback options (shuffle, loop). If it doesn't work as is, try to add those parameters to the setTimeout as well.

I'm currently doing measures on the quality of a video youtube depending on given network conditions. I wrote a custom Chrome extension to play videos and get buffering informations thanks to the youtube player api.
What I would need now is the content of the 'Stats for nerds' panel that appears when you right-click on the video (example).
I can display it thanks to UI automation. But, when I try to access the content of this panel with javascript, I get an error because of Cross-origin resource sharing (CORS).
I only want to read the Current/OptimalRes of the panel. Do you have any idea of a way to get it?
I've been searching for an answer to this question for long now. It has been mentioned here, but the answer to this post is not what I'm looking for as it only gives the general information about the video, not the resolution that is actually being played.
Apologies that this code is in 'AutoIT', but it should be easy to pipe to Javascript or any other similar language. This is a complete list of the 'Stats for Nerds' data:
#include <IE.au3>
;Attach to open YouTube player within browser
$oIE = _IEAttach ("https://www.youtube.com", "url",1)
;Get a reference to the movie player
$oPlayerRef = $oIE.document.getElementById("movie_player")
;Video ID / sCPN
msgbox(0,"",$oPlayerRef.getStatsForNerds(0).video_id_and_cpn)
;Viewport / Frames
msgbox(0,"",$oPlayerRef.getStatsForNerds(0).dims_and_frames)
;Current / Optimal Res
msgbox(0,"",$oPlayerRef.getStatsForNerds(0).resolution)
;Volume / Normalized
msgbox(0,"",$oPlayerRef.getStatsForNerds(0).volume)
;Codecs
msgbox(0,"",$oPlayerRef.getStatsForNerds(0).codecs)
;Connection Speed
msgbox(0,"",$oPlayerRef.getStatsForNerds(0).bandwidth_kbps)
;Network Activity

;Buffer Health

player.getPlaybackQuality();

Youtube's IFrame API is not working for me anymore. Both onYouTubeIframeAPIReady() and onYouTubePlayerReady() gets executed. However, when try loading/playing a video, I receive the following error:
base.js:2575 Uncaught TypeError: Cannot read property 'g' of null

Here is how I use the IFrame API
// Load YouTube Player
var tag = document.createElement('script');
tag.src = "https://www.youtube.com/iframe_api";
var firstScriptTag = document.getElementsByTagName('script')[0];
firstScriptTag.parentNode.insertBefore(tag, firstScriptTag);
// Create YouTube Player
var jukeBoxYoutubePlayer;
function onYouTubeIframeAPIReady() {
console.log("iframe api ready");
jukeBoxYoutubePlayer = new YT.Player('youtube_player', {
height: '400px',
width: '400px',
events: {
'onReady': onYouTubePlayerReady
}
});
}
// On Ready Event
function onYouTubePlayerReady(event) {
console.log("player ready");
jukeBoxYoutubePlayer.unMute();
jukeBoxYoutubePlayer.setVolume(75);
}
Here is how I load and play a video:
jukeBoxYoutubePlayer.loadVideoById("ubtbkgUmHHE", 0, "large");
jukeBoxYoutubePlayer.playVideo();
I don't see why my code is not working. It has been working for months. I also re-checked the docs (https://developers.google.com/youtube/iframe_api_reference) for any new changes, but can't find any.
It seems the issue was that my "youtube_player" iframe was hidden by CSS display:none. Apparently, YouTube requires the iframe to be visible. However, sizing the iframe to 1x1 px solved it for me.
Right, this seems to be poorly documented or I can't see it in the documentation. I basically want no related videos (?rel=0) using the JavaScript API.
$players[$vidIdPlaceholderRef] = new YT.Player('player_' + $vidIdPlaceholderRef, {
height: '550',
width: '840',
videoId: $vidId
});
is what I have in place.
I have also tried:
$players[$vidIdPlaceholderRef] = new YT.Player('player_' + $vidIdPlaceholderRef, {
height: '550',
width: '840',
videoId: $vidId + '?rel=0',
rel : 0
});
with no luck. Does any one know of an option which can be added (tried rel : 0 with no luck )
"rel" is a player parameter, as specified here:
https://developers.google.com/youtube/player_parameters#rel
To add player parameters to iframe players, you need to specify the playerVars property of the second constructor argument (at the time of writing this is documented here, and on the IFrame API documentation page)
e.g.
new YT.Player('playerid', {
height: '550',
width: '840',
videoID: 'video_id',
playerVars: {rel: 0, showinfo: 0, ecver: 2}
});
The behavior of the rel player parameter has changed.
From documentation,
The behavior for the rel parameter is changing on or after September
25, 2018. The effect of the change is that you will not be able to
disable related videos. However, you will have the option of
specifying that the related videos shown in the player should be from
the same channel as the video that was just played
So, it's no longer possible to disable related videos. Instead playerVars: {rel:0} will change the behavior of the player and shows suggestion from specified channel.
You get related videos in two places: at the end of the video with the grid, and at the bottom of the video while paused. I've figured out a way to remove them at the end and make the ones at the bottom at least tolerable for most businesses.
1. Remove related videos at the end of a video
IFrame Player API: Events
To avoid showing related videos at the end of a video, I just stopped the video so it returned to showing the thumbnail and play button:
var player = new YT.Player('player', {
height: '390',
width: '640',
events: {
'onStateChange': function(event){
switch(event.data){
// Stop the video on ending so recommended videos don't pop up
case 0: // ended
player.stopVideo();
break;
case -1: // unstarted
case 1: // playing
case 2: // paused
case 3: // buffering
case 5: // video cued
default:
break;
}
}
}
});
You could also replace player.stopVideo(); with any other code you want to run.
2. Making related videos at the bottom of a video only show your videos
IFrame Player API: YouTube Embedded Players and Player Parameters
rel=0 no longer avoids showing any related videos; now, it will still show related videos, but at least they'll only be from your channel. This changed sometime around September 25, 2018 (documentation).
By setting playerVars in YT.Player, we can at least have related videos only show our channel's videos. The documentation isn't clear that you have to have playerVars set up as an object, but you can set it up like so:
var player = new YT.Player('player', {
...
playerVars:{
rel: 0
modestbranding: 1, // If you're trying to remove branding I figure this is helpful to mention as well; removes the YouTube logo from the bottom controls of the player
// color: 'white', // Can't have this and modestbranding active simultaneously (just a note in case you run into this)
},
...
});
2A. Potential way to remove related videos from bottom
I may look more into it if I have the time, but here's where an answer may lie:
We can easily access the iframe object but we can't do anything with it: IFrame Player API: Accessing and modifying DOM nodes. It appears that because we'd be editing an iframe from YouTube there are security concerns (regardless of what we'd actually be doing). Ideally I could just remove the "More videos" text with player.getIframe().contentWindow.document.querySelector('.ytp-pause-overlay.ytp-scroll-min').remove(), but when I run player.getIframe().contentWindow.document I get an error SecurityError: Permission denied to access property "document" on cross-origin object.
But playerVars also has an origin value that may let us access the iframe's object anyway:
var player = new YT.Player('player', {
...
playerVars:{
origin: 'https://mywebsite.com'
},
...
});
It's not working with localhost, but that may be a Chromium and Firefox thing. Perhaps this is a legitimate option on a live site; I'll update this post when/if I try that to let you know if I succeed.
The accepted solution was not working for me. What does work is:
1) Putting the iframe in html that includes the rel parameter
<iframe id="youtube-video" width="560" height="315"
src="https://www.youtube.com/embed/M7lc1UVf-VE?enablejsapi=1&rel=0&modestbranding=1"
frameborder="0" enablejsapi="1" allowfullscreen></iframe>
2) Using the javascript API to attach to that existing player
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('youtube-video', {
events: {
'onReady': onPlayerReady,
'onStateChange': onPlayerStateChange
}
});
}
function onPlayerReady(event) {
console.log("ready");
}
function onPlayerStateChange(event) {
console.log("state changed");
}
demo fiddle: http://jsfiddle.net/bf7zQ/195/
If you're using SWFObject, you simply need to do something like this:
function loadVideo() {
var params = { allowScriptAccess: "always" }
, atts = { id: "myvideo" }
;
//NOTE THE END OF THE BELOW LINE vvvvvv
swfobject.embedSWF("https://www.youtube.com/v/[video id here]?enablejsapi=1&playerapiid=myvideo&version=3&rel=0"
, "videoplaceholderid"
, "768", "432", "8", null, null, params, atts);
}
Just add rel=0 to the end of your url.
No need to code through the API,now its easily can be done by
You tube embed button -> Show more -> tickout the option 'Show suggested videos when the video finishes'
Here is a Quick solution:
setInterval(function(){
if($('iframe').length > 0){
$('iframe').each(function(){
if($(this).hasClass('gotYou')){
//do nothing
}else{
var getMySrc = $(this).attr('src');
var newSrc = getMySrc.split('?');
console.log(newSrc);
var freshURL = newSrc[0]+'?rel=0&'+newSrc[1];
console.log(freshURL);
$(this).addClass('gotYou');
$(this).attr('src', freshURL );
}
});
}
}, 1);
What it does it, it looks for the iframe in your document. If it finds iframe, it grabs the src of the iframe, finds the ? mark and then replaces ? by ?rel=0& . Here the goal is to out rel=0
new YT.Player('playerid', {
height: '550',
width: '840',
videoID: 'video_id',
playerVars: {rel: 0},
});
