Overview

A reference client implementation for the playback of MPEG DASH via JavaScript and compliant browsers. Learn more about DASH IF Reference Client on our wiki.

If your intent is to use the player code without contributing back to this project, then use the MASTER branch which holds the approved and stable public releases.

If your goal is to improve or extend the code and contribute back to this project, then you should make your changes in, and submit a pull request against, the DEVELOPMENT branch. Read our CONTRIBUTION.md file for a walk-through of the contribution process.

All new work should be in the development branch. Master is now reserved for tagged builds.

Demo and reference players

All these reference builds and minified files are available under both http and https.

$3

Multiple dash.js samples covering a wide set of common use cases.

$3

The released pre-built reference players if you want direct access without writing any Javascript.

The nightly build of the /dev branch reference player, is pre-release but contains the latest fixes. It is a good place to start if you are debugging playback problems.

The latest minified files have been hosted on a global CDN and are free to use in production:

- dash.all.min.js
- dash.all.debug.js

In addition, all the releases are available under the following urls. Replace "vx.x.x" with the release version, for instance "v3.1.0".

- http://cdn.dashjs.org/vx.x.x/dash.all.min.js
- http://cdn.dashjs.org/vx.x.x/dash.all.debug.js

If you are migrating from dash.js v2.x to dash.js v3.x please read the migration document found here.

Getting Started

The standard setup method uses javascript to initialize and provide video details to dash.js. MediaPlayerFactory provides an alternative declarative setup syntax.

$3

Create a video element somewhere in your html. For our purposes, make sure the controls attribute is present.
``html

`
Add dash.all.min.js to the end of the body.
`html

...


`
Now comes the good stuff. We need to create a MediaPlayer and initialize it.
` js

var url = "https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd";
var player = dashjs.MediaPlayer().create();
player.initialize(document.querySelector("#videoPlayer"), url, true);

`

When it is all done, it should look similar to this:
`html














`

$3

We publish dash.js to npm. Examples of how to use dash.js in different module
bundlers can be found in the samples/modules directory.

$3

An alternative way to build a Dash.js player in your web page is to use the MediaPlayerFactory. The MediaPlayerFactory will automatically instantiate and initialize the MediaPlayer module on appropriately tagged video elements.

Create a video element somewhere in your html and provide the path to your mpd file as src. Also ensure that your video element has the data-dashjs-player attribute on it.
`html


`

Add dash.all.min.js to the end of the body.
`html

...


`

When it is all done, it should look similar to this:
`html
