[javascript] HTML 5 video or audio playlist

Can I use a <video> or <audio> tag to play a playlist, and to control them?

My goal is to know when a video/song has finished to play and take the next and change its volume.

You should take a look at Popcorn.js - a javascript framework for interacting with Html5 : http://popcornjs.org/documentation

I created a JS fiddle for this here:

http://jsfiddle.net/Barzi/Jzs6B/9/

First, your HTML markup looks like this:

<video id="videoarea" controls="controls" poster="" src=""></video>

<ul id="playlist">
    <li movieurl="VideoURL1.webm" moviesposter="VideoPoster1.jpg">First video</li>
    <li movieurl="VideoURL2.webm">Second video</li>
    ...
    ...
</ul>

Second, your JavaScript code via JQuery library will look like this:

$(function() {
    $("#playlist li").on("click", function() {
        $("#videoarea").attr({
            "src": $(this).attr("movieurl"),
            "poster": "",
            "autoplay": "autoplay"
        })
    })
    $("#videoarea").attr({
        "src": $("#playlist li").eq(0).attr("movieurl"),
        "poster": $("#playlist li").eq(0).attr("moviesposter")
    })
})?

And last but not least, your CSS:

#playlist {
    display:table;
}
#playlist li{
    cursor:pointer;
    padding:8px;
}
#playlist li:hover{
    color:blue;                        
}
#videoarea {
    float:left;
    width:640px;
    height:480px;
    margin:10px;    
    border:1px solid silver;
}?

jPlayer is a free and open source HTML5 Audio and Video library that you may find useful. It has support for playlists built in: http://jplayer.org/

I optimized the javascript code from cameronjonesweb a little bit. Now you can just add the clips into the array. Everything else is done automatically.

<video autoplay controls id="Player" src="http://www.w3schools.com/html/movie.mp4" onclick="this.paused ? this.play() : this.pause();">Your browser does not support the video tag.</video>

<script>
var nextsrc = ["http://www.w3schools.com/html/movie.mp4","http://www.w3schools.com/html/mov_bbb.mp4"];
var elm = 0; var Player = document.getElementById('Player');
Player.onended = function(){
    if(++elm < nextsrc.length){         
         Player.src = nextsrc[elm]; Player.play();
    } 
}
</script>

Yep, you can simply point your src tag to a .m3u playlist file. A .m3u file is easy to construct -

#hosted mp3's need absolute paths but file system links can use relative paths
http://servername.com/path/to/mp3.mp3
http://servername.com/path/to/anothermp3.mp3
/path/to/local-mp3.mp3

-----UPDATE-----

Well, it turns out playlist m3u files are supported on the iPhone, but not on much else including Safari 5 which is kind of sad. I'm not sure about Android phones but I doubt they support it either since Chrome doesn't. Sorry for the misinformation.

It has been done there : http://www.jezra.net/projects/pageplayer

You can add an event listener with 'ended' as the first param

I wasn't satisfied with what was offered, so here's my proposal, using jQuery :

            <div id="playlist">
                <audio id="player" controls preload="metadata" volume="1">
                  <source src="" type="audio/mpeg">
                  Sorry, this browser doesn't support HTML 5.0
                </audio>
                <ul></ul>
            </div>

            <script>
                var folder = "audio";
                var playlist = [
                    "example1.mp3",
                    "example2.mp3"
                ];
                for (var i in playlist) {
                    jQuery('#playlist ul').append('<li>'+playlist[i]+'</li>');
                }

                var player = document.getElementById('player');
                var playing = playlist[0];
                player.src = folder + '/' + playing;

                function display(id) {
                    var list = jQuery('#playlist ul').children();
                    list.removeClass('playing');
                    jQuery(list[id]).addClass('playing');
                }

                display(0);

                player.onended = function(){
                    var ind_next = playlist.indexOf(playing) + 1;

                    if (ind_next !== 0) {
                        player.src = folder + '/' + playlist[ind_next];
                        playing = player.src;
                        display(ind_next)
                        player.play();
                    }
                }
            </script>

You only have to edit the playlist array, and you're done

There's no way to define a playlist using just a <video> or <audio> tag, but there are ways of controlling them, so you can simulate a playlist using JavaScript. Check out sections 4.8.7, 4.8.9 (especially 4.8.9.12) of the HTML5 spec. Hopefully the majority of methods and events are implemented on modern browsers such as Chrome and Firefox (latest versions, of course).

To add to the current answers, here is a playlist of videos which works with separate subtitle files. At the end of the playlist, it will go to endPage

<video id="video" controls autoplay preload="metadata">
   <source src="vid1.mp4" type="mp4">
   <track id="subs" label="English" kind="subtitles" srclang="en" src="sub1.vtt" default>
</video>

<script type="text/javascript">
var endPage = "duckduckgo.com";
var playlist = [
    { 
        'file': 'vid2.mp4',
        'subtitle': 'sub2.vtt'
    },{
        'file': 'vid3.mp4',
        'subtitle': 'sub3.vtt'
    }
]
var i = 0;
var videoPlayer = document.getElementById('video');
var subtitles = document.getElementById('subs');
videoPlayer.onended = function(){
    if(i < playlist.length){
        videoPlayer.src = playlist[i].file;
        subtitles.src = playlist[i].subtitle;
        i++;
    } else {
        console.log("We are leaving")
        document.location.href = endPage;
    }
}
</script>

Try this solution, it takes an array of soundtracks and plays all of them, playlist-style, and even loops the playlist. The following uses a little Jquery to shorten getting the audio element. If you do not wish to use Jquery, replace the first line of the javascript with var audio = document.getElementById("audio"); and it will work the same.

Javascript:

var audio = $("#audio")[0];
var tracks = {
    list: ["track_01.mp3", "track_02.mp3", "track_03.mp3"], //Put any tracks you want in this array
    index: 0,
    next: function() {
        if (this.index == this.list.length - 1) this.index = 0;
        else {
            this.index += 1;
        }
    },
    play: function() {
        return this.list[this.index];
    }
}

audio.onended = function() {
    tracks.next();
    audio.src = tracks.play();
    audio.load();
    audio.play();
}

audio.src = tracks.play();

HTML:

<audio id="audio" controls>
    <source src="" />
</audio>

This will allow you to play as many songs as you want, in playlist style. Each song will start as soon as the previous one finishes. I do not believe this will work in Internet Explorer, but it's time to move on from that ancient thing anyways!

Just put any songs you want into the array tracks.list and it will play all of them one after the other. It also loops back to the first song once it's finished with the last one.

It's shorter than many of the answers, it accounts for as many tracks as you want, it's easily understandable, and it actually loads the audio before playing it (so it actually works), so I thought I would include it here. I could not find any sound files to use in a running snippet, but I tested it with 3 of my own soundtracks on Chrome and it works. The onended method, which detects the ended event, also works on all browsers except Internet Explorer according to caniuse.

NOTE: Just to be clear, this works with both audio and video.
