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.

Documentation

Before you get started, please read the Dash.js v2.0 Migration Document found here

Full API Documentation is available describing all public methods, interfaces, properties, and events.

For help, join our Slack channel, our email list and read our wiki.

Reference players

The released pre-built reference players are publicly accessible 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.

A nightly build of the latest minified files are also available: dash.all.min.js and its debug version dash.all.debug.js.

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

Quick Start for Users

If you just want a DASH player to use and don't need to see the code or commit to this project, then follow the instructions below. If you are a developer and want to work with this code base, then skip down to the “Quick Start for Developers” section.

Put the following code in your web page

ipt src="https://cdn.dashjs.org/latest/dash.all.min.js"></script>

le>
video {
   width: 640px;
   height: 360px;
}
yle>

y>
div>
   <video data-dashjs-player autoplay src="https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd" controls></video>
/div>
dy>

Then place your page under a web server (do not try to run from the file system) and load it via http in a MSE-enabled browser. The video will start automatically. Switch out the manifest URL to your own manifest once you have everything working. If you prefer to use the latest code from this project (versus the last tagged release) then see the “Quick Start for Developers” section below.

View the /samples folder for many other examples of embedding and using the player. If you are interested in captioning support, which requires some additional UI elements, then please view the captioning examples.

Quick Start for Developers
  1. Install Core Dependencies
  2. Checkout project repository (default branch: development)
  3. Install dependencies
  4. Build, watch file changes and launch samples page, which has links that point to reference player and to other examples (basic examples, captioning, ads, live, etc).
Other Grunt Tasks to Build / Run Tests on Commandline.
  1. Individual tasks:
    • Quickest build
    • Lint
    • Run unit tests
    • Build distribution files (minification included)
    • Build distribution files, lint, run unit tests and generate documentation
  2. GruntFile.js default task (equivalent to `grunt dist && grunt test`)
Getting Started

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

Standard Setup

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

eo id="videoPlayer" controls></video>

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

y>
.
cript src="yourPathToDash/dash.all.min.js"></script>
dy>

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

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

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

ctype html>
l>
<head>
    <title>Dash.js Rocks</title>
    <style>
        video {
            width: 640px;
            height: 360px;
        }
    </style>
</head>
<body>
    <div>
        <video id="videoPlayer" controls></video>
    </div>
    <script src="yourPathToDash/dash.all.min.js"></script>
    <script>
        (function(){
            var url = "https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd";
            var player = dashjs.MediaPlayer().create();
            player.initialize(document.querySelector("#videoPlayer"), url, true);
        })();
    </script>
</body>
ml>
Module Setup

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.

MediaPlayerFactory Setup

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.

eo data-dashjs-player autoplay src="https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd" controls>
deo>

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

y>
.
cript src="yourPathToDash/dash.all.min.js"></script>
dy>

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

ctype html>
l>
<head>
    <title>Dash.js Rocks</title>
    <style>
        video {
            width: 640px;
            height: 360px;
        }
    </style>
</head>
<body>
    <div>
        <video data-dashjs-player autoplay src="https://dash.akamaized.net/envivio/EnvivioDash3/manifest.mpd" controls>
        </video>
    </div>
    <script src="yourPathToDash/dash.all.min.js"></script>
</body>
