Play multiple audio tracks sequentially, not simultaneously

I'm trying to use the <audio> tag, and I want to have as many tracks playing as I add. But now they play at the same time, can I somehow make them play sequentially?
<audio id="audio1" preload="" autoplay="" loop="" type="audio/mp3" src="music/mus1.mp3"></audio>
<audio id="audio2" preload="" autoplay="" loop="" type="audio/mp3" src="music/mus.mp3"></audio>
<div id="pp" style="cursor: pointer;" onclick="pVid();"><img src="img/heart.png"></div>
<script type="text/javascript">
function pVid() {
var audio1 = document.getElementById("audio1");
var audio2 = document.getElementById("audio2");
audio1.paused ? audio1.play() : audio1.pause();
audio2.paused ? audio2.play() : audio2.pause();
}
</script>
I found one solution, it works but not the way I want
var sounds = new Array(new Audio("music/mus1.mp3"), new Audio("music/mus.mp3"));
var i = -1;
pVid();
function pVid() {
i++;
if (i == sounds.length) return;
sounds[i].addEventListener('ended', pVid);
sounds[i].play();
}
Here everything just plays right away, but I want to be able to play the tracks myself through the button and pause at any time. This is done in the first version, but there all the tracks play at the same time

Use audio events as much as possible. We can use freesound.org for testing.
let sounds = new Array(new Audio("https://freesound.org/data/previews/46/46992_514283-lq.mp3"),
new Audio("https://freesound.org/data/previews/610/610823_13156161-lq.mp3"),
new Audio("https://freesound.org/data/previews/92/92005_1499847-lq.mp3"), new Audio("https://freesound.org/data/previews/46/46992_514283-lq.mp3"),
new Audio("https://freesound.org/data/previews/610/610823_13156161-lq.mp3"),
new Audio("https://freesound.org/data/previews/92/92005_1499847-lq.mp3"));
let current = random(0);
let paused = true;
// set event handlers on all audio objects
for (let s of sounds) {
s.addEventListener('ended', ended);
s.addEventListener('play', play);
s.addEventListener('pause', pause);
}
updateVolume()
// handle button click
function playPause() {
if (paused) {
sounds[current].play();
btn.innerText = 'pause';
paused = false;
} else {
sounds[current].pause();
btn.innerText = 'play';
paused = true;
}
}
function ended(e) {
document.getElementById(current + '').classList.remove('playing');
document.getElementById(current + '').classList.remove('paused');
/*i++;
if (i >= sounds.length) //loop
i = 0;
*/
current = random(current); // shuffle
paused = true;
playPause();
}
function play() {
document.getElementById(current + '').classList.add('playing');
document.getElementById(current + '').classList.remove('paused');
}
function pause() {
document.getElementById(current + '').classList.add('paused');
document.getElementById(current + '').classList.remove('playing');
}
function random(i) {
let next = i;
while (next == i)
next = Math.floor(Math.random() * sounds.length);
return next;
}
function updateVolume() {
for (let s of sounds) {
s.volume = volume.value;
}
}

I don't know why no one mentioned the onended event
<audio id="aud1" onended="playaud2()" src="whatever.mp3"> <!--first audio-->
<audio id="aud2" src="whatever.mp3"> <!--second audio-->
<script>
//the onended event calls a function when the audio finishes playing
function playaud2() {
document.getElementById("aud2").play()}
</script>
As simple :)

Audio files
For testing, I used a few free sound-effects audio files from https://www.freesoundeffects.com.
To make it work in all browsers it is recommended by w3c to use the <audio>-tag with <source> tags.
Solution
I added some arbitrary sound files and buttons. The buttons will reset all the audios that are currently playing then play the sounds in the data-track attributes.
data-track syntax:
track-a // will play track a
track-a;track-b // will play track a followed by track b
track-a+track-b // will play track a and b simultaniously
track-a+track-b;track-c // as above but add track c to the end
You could do something like this:
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<style type="text/css">
audio {
display: block;
}
</style>
<script defer type="application/javascript">
let activeTimeout;
function init(player) {
player.innerHTML = `play ${player.dataset.label}`;
player.addEventListener('click', clickHandler);
}
function reset(audio) {
clearTimeout(activeTimeout);
audio.pause();
audio.currentTime = 0;
}
function dequeue(tracks) {
console.log("Queue:", tracks);
if (tracks.length >= 1) {
const track = tracks.pop();
const multiTrack = track.split('+');
let maxDuration = 0;
multiTrack.forEach((it) => {
const audio = document.querySelector(`[data-audio="${it}"]`);
maxDuration = Math.max(maxDuration, audio.duration);
audio.play();
});
activeTimeout = setTimeout(() => {
dequeue(tracks);
}, maxDuration * 1000);
}
}
function clickHandler(e) {
const allAudios = document.querySelectorAll('[data-audio]');
const trackAttr = this.dataset.track;
const tracks = trackAttr.split(';');
if (tracks) {
allAudios.forEach(reset);
dequeue(tracks.reverse()); // reverse to make the pop-operations faster
} else {
console.log('No track defined!');
}
}
window.addEventListener('load', function() {
const players = document.querySelectorAll('[data-player]');
players.forEach((it) => init(it));
});
</script>
</head>

Yes, you can check if you have an element with a simple truthy/falsy check:
if (!slider) return;

embedding multiple Youtube livestream and manage display with buttons

I am trying to setup a website page where 2 permanent live streams (from 2 different channels) are embedded. 2 buttons are present on the page, allowing the user to display 1 video or the other.
However I can't manage to make this work. I am now trying with regular youtube embed, but only one is displaying, the buttons don't have any effect. Also the autoplay doesn't seem to work...
I already tried the Livestream part, this works well, but not with 2 livestreams.
Any advice where to look into. Thank you !
function showcam(num) {
for (let i = 1; i < 2; i++) {
document.getElementById("camera" + i).style.display = 'none';
}
document.getElementById("camera" + num).style.display = '';
console.log(num)

You have to use the iframe api in order to be able to control the video. From there, you'll be able to add more than 1 video and do make your own play buttons or toggle between them. If you need further help, I can try and give you an example that toggles between 2 videos.

How to disable "related videos" from an embedded youtube playlist

I need to embed a Youtube playlist on an iframe. I don't want the user to be able to exit this playlist, so I need to disable the "related video" and "more video" features (the one that shows more videos when the video is stopped and the one that shows them when the video is finished).
I've tested some workarounds but they only used to work for single videos (not playlist) and most of them stopped working after they changed the way ?rel=0 behaves. Is there any way to do this?
This is my code:
.rep {
position: absolute;
top: 0px;
left: 0px;
width: 1280px;
height: 640px;
z-index: 6;
}
<iframe class="rep" src="https://www.youtube.com/embed/videoseries?list=PLUl4u3cNGP63gFHB6xb-kVBiQHYe_4hSi" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
EDIT: The videos must be shown in order, therefore I can't use rel to display only videos from the playlist. Plus, if you click on them a youtube page outside of the iframe will appear.

If I look through the YouTube Embedded Players and Player Parameters docs, there is no such thing to order the more videos section if you pause the video.
The two parameters I suggest to get near as possible to your goal is:
You can add:
listType=playlist
rel=0 to turn off related videos from the more videos section.
Note: The behaviour of rel=0 will be removed after September 25, 2019.
Conclusion:
It seems like what you want to achieve is not possible. With the default embed iframe of YouTube.
You might want to consider to look to other players with playlist options. Something like JW Player note that you need a licence for this player, JW Player playlist docs. I did some reading on JW Player as well, they currently don't support YouTube videos.
But maybe there are other players that have the same functionally for free.

If you add &rel=0 at the end of playlist link - in related videos will be showed only videos from your playlist. Example:
<iframe class="rep" src="https://www.youtube.com/embed/videoseries?list=PLUl4u3cNGP63gFHB6xb-kVBiQHYe_4hSi&rel=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
If you remove &rel=0 from the link, it show random videos from youtube

Update for 2021
Youtube now seems to have a loop function that can be used to git rid of “related videos”. What it does basically is that when your video ends, it restarts again instead of showing (un)related videos. It worked perfectly in my case. Here is the code:
https://www.youtube.com/embed/VIDEO_ID?playlist=VIDEO_ID&loop=1
Please make sure to replace both VIDEO_ID in the code with your video ID. N̲o̲ N̲e̲e̲d̲ for creating a playlist
Example of full iframe code with player controls being enabled
<iframe width="560" height="315" src="https://www.youtube.com/embed/VIDEO_ID?playlist=VIDEO_ID&loop=1" title="YouTube video player" rel="0" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
Example of full iframe code with player controls being disabled
<iframe width="560" height="315" src="https://www.youtube.com/embed/VIDEO_ID?playlist=VIDEO_ID&loop=1&controls=0" title="YouTube video player" rel="0" frameborder="0" allow="accelerometer; autoplay; clipboard-write; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>

Here is a work around not the best but it will stop them annoy recommendations. It loops the playlist never giving youtube a chance to stop and give you there recommendations to get users back to youtube. This has worked well for me. If you see it plays my list in the loop and then plays the next, all without ever bringing up the recommendations. if you stop it it just stays there. Hope it helps they key is 0&loop

It can not be done after September 25, 2018. The effect of the change is that you will not be able to disable related videos. Below is the YouTube official post link of it.

Thanks

I just found a great website that found a fix for your problem. The code is a bit long, but I think it works. They have an example if you scroll up a bit. https://www.maxlaumeister.com/blog/hide-related-videos-in-youtube-embeds/#hideyt-embed-code

In my case this is working you can try this :
https://www.youtube-nocookie.com/embed/{videoId}?rel=0&showinfo=0

Unfortunately, external CSS or JS can't be applied to iframe videos or iframe contents in a webpage.
For now, you can add rel=0 parameter to the video URL in iframe code. As per youtube documentations, rel=0 parameter will be disabled after Sep 25 2019.
Here is an example with rel=0 parameter
<iframe width="560" height="315" src="https://www.youtube.com/embed/J8Rt6HSzrqY&rel=0" frameborder="0" allow="accelerometer; autoplay; encrypted-media; gyroscope; picture-in-picture" allowfullscreen></iframe>
You can also use the playlist feature or parameter. See example below:
<iframe width="560" height="315" src="https://www.youtube.com/embed/videoseries?list=PLx0sYbCqOb8TBPRdmBHs5Iftvv9TPboYG&rel=0" frameborder="0" allow="autoplay; encrypted-media" allowfullscreen></iframe>
Above code is taken from Official Youtube Support documents. You can add only one video in the list so that it does not play any other video after the current video finishes.

Based on the work of Maximillian Laumeister hideyt I forged a JS which can be included anywhere and autoamtically wraps its magic around every embedded youtube iframe you have.

I found out that if the youtube channel the video is from has less than (I don't know how many exactly but definitely more than 20 and less than 40) videos and the iframe youtube url has the rel=0 attribute, it won't show the related videos section at all.

How to automatically play a short video clip on HTML5 canvas?

I have made a simple game using canvas, but I can't seem to figure out how to get a quick 3 second intro to play just once within my canvas (before canvas is drawn).
This is what I've got for my html:
<video id="intro" src="https://www.youtube.com/watch?v=tqErAlg-QJU" controls="false" autoplay></video>
<canvas id="myCanvas" width="800" height="400"
style="border:1px solid #000000;">
</canvas>

Here you have an example, just handle the play event so when the video autoplay run, the canvas draw a copy of that video.
document.addEventListener('DOMContentLoaded', function(){

My proposal, using your youtube video is:
use youtube api
refer only to your videoId
toggle visibility
var player;
function onYouTubeIframeAPIReady() {
player = new YT.Player('player', {
height: '400',
width: '800',
videoId: 'tqErAlg-QJU',
events: {
'onReady': function (e) {
e.target.playVideo();
// pause video after 3 seconds
setTimeout(function() {
player.pauseVideo();
}, 3 * 1000);
},
'onStateChange': function (e) {
// if video ended (0) or paused (2)....
if (e.data == 0 || e.data == 2) {
// remove the player
player.destroy();
// toggle the visibility
$('#myCanvas, #player').toggle();
}
}
}
});
}
$(function () {
$('#myCanvas').hide();
});

fullscreen vimeo trigger event on customize button

Is there a way to trigger fullscreen mode on Vimeo player using JavaScript ?
I want to hide all controls of player and i have a side Customize button that i want trigger fullscreen.
<script src="//f.vimeocdn.com/js/froogaloop2.min.js"></script>
<iframe id="player1" src="//player.vimeo.com/video/76979871?api=1&player_id=player1" width="630" height="354" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>
<div>
<button>Play</button>
<button>Pause</button>
<button class="fullscreen">FullScreen</button>
</div>
$(function() {
var iframe = $('#player1')[0];
var player = $f(iframe);
// When the player is ready, add listeners for pause, finish, and playProgress
player.addEvent('ready', function() {
status.text('ready');
player.addEvent('pause', onPause);
player.addEvent('finish', onFinish);
player.addEvent('playProgress', onPlayProgress);
});
// button to trigger fullscreen
$('button.fullscreen').bind('click', function() {
// here i want trigger fullscreen on player Vimeo
});
});

Unfortunately, no. The Fullscreen API requires a direct user action and that action is lost on the postMessage to the player.

Set the embed iframe size at 100% for width and height and put it in a div. Then, you can manage the div size.
It's not a real fullscreen but it can use all the size of your browser window.
