Update: Big changes coming in Video.js 10, early 2026! Read the discussion.
Video.js is a full featured, open source video player for all web-based platforms.
Right out of the box, Video.js supports all common media formats used on the web including streaming formats like HLS and DASH. It works on desktops, mobile devices, tablets, and web-based Smart TVs. It can be further extended and customized by a robust ecosystem of plugins.
Video.js was started in May 2010 and since then:
- Millions of websites have used VideoJS over time (source Builtwith)
- Billions of end-users every month of just the CDN-hosted copy (source Fastly stats)
- 900+ amazing contributors to the video.js core
- Hundreds of plugins
Thanks to the awesome folks over at Fastly, there's a free, CDN hosted version of Video.js that anyone can use. Add these tags to your document's <head>:
<link href="//vjs.zencdn.net/8.24.1/video-js.min.css" rel="stylesheet">
<script src="//vjs.zencdn.net/8.24.1/video.min.js"></script>Alternatively, you can include Video.js by getting it from npm, downloading it from GitHub releases or by including it via unpkg or another JavaScript CDN, like CDNjs.
<!-- unpkg : use the latest version of Video.js -->
<link href="https://unpkg.com/video.js/dist/video-js.min.css" rel="stylesheet">
<script src="https://unpkg.com/video.js/dist/video.min.js"></script>
<!-- unpkg : use a specific version of Video.js (change the version numbers as necessary) -->
<link href="https://unpkg.com/video.js@8.24.1/dist/video-js.min.css" rel="stylesheet">
<script src="https://unpkg.com/video.js@8.24.1/dist/video.min.js"></script>
<!-- cdnjs : use a specific version of Video.js (change the version numbers as necessary) -->
<link href="https://cdnjs.cloudflare.com/ajax/libs/video.js/8.24.1/video-js.min.css" rel="stylesheet">
<script src="https://cdnjs.cloudflare.com/ajax/libs/video.js/8.24.1/video.min.js"></script>Next, using Video.js is as simple as creating a <video> element, but with an additional data-setup attribute. At a minimum, this attribute must have a value of '{}', but it can include any Video.js options - just make sure it contains valid JSON!
<video
id="my-player"
class="video-js"
controls
preload="auto"
poster="//vjs.zencdn.net/v/oceans.png"
data-setup='{}'>
<source src="//vjs.zencdn.net/v/oceans.mp4" type="video/mp4"></source>
<source src="//vjs.zencdn.net/v/oceans.webm" type="video/webm"></source>
<source src="//vjs.zencdn.net/v/oceans.ogv" type="video/ogg"></source>
<p class="vjs-no-js">
To view this video please enable JavaScript, and consider upgrading to a
web browser that

supports HTML5 video
</a>
</p>
</video>When the page loads, Video.js will find this element and automatically setup a player in its place.
If you don't want to use automatic setup, you can leave off the data-setup attribute and initialize a <video> element manually using the videojs function:
var player = videojs('my-player');The videojs function also accepts an options object and a callback to be invoked when the player is ready:
var options = {};
var player = videojs('my-player', options, function onPlayerReady() {
videojs.log('Your player is ready!');
// In this context, `this` is the player that was created by Video.js.
this.play();
// How about an event listener?
this.on('ended', function() {
videojs.log('Awww...over so soon?!');
});
