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 through our wiki section on https://github.com/Dash-Industry-Forum/dash.js/wiki/How-to-Contribute for a walk-through of the contribution process.

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

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

<script src="http://cdn.dashjs.org/latest/dash.all.js"></script>
...
<body onLoad="Dash.createAll()">
   <div>
       <video class="dashjs-player" autoplay preload="none" controls="true">
              <source src="http://dash.edgesuite.net/envivio/dashpr/clear/Manifest.mpd" type="application/dash+xml"/>
       </video>
   </div>
</body>

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 download dash.all.js file from the development/dist folder, mount it on a web server and change your script tag to refer to it.

View the /samples folder for many other examples of embedding and using the player. For help, join our email list and read our wiki .

Quick Start for Developers

Reference Player

  1. Download 'master' or latest tagged release.
  2. Extract dash.js and move the entire folder to localhost (or run any http server instance such as python's SimpleHTTPServer at the root of the dash.js folder).
  3. Open samples/dash-if-reference-player/index.html in your MSE capable web browser.

Install Dependencies

  1. install nodejs
  2. install grunt
    • npm install -g grunt-cli

Build / Run tests

  1. Change directories to the build folder
    • cd build/
  2. Install all Node Modules defined in package.json
    • npm install
  3. Run all the GruntFile.js task (Complete Build and Test)
    • grunt
  4. You can also target individual tasks:
    • grunt uglify
    • grunt jsdoc
    • grunt jshint

Getting Started

Create a video element somewhere in your html. For our purposes, make sure to set the controls property to true.

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

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

<body>
  ...
  <script src="yourPathToDash/dash.all.js"></script>
</body>

Now comes the good stuff. We need to create a dash context. Then from that context we create a media player, initialize it, attach it to our "videoPlayer" and then tell it where to get the video from. We will do this in an anonymous self executing function, that way it will run as soon as the page loads. So, here is how we do it:

(function(){
    var url = "http://dash.edgesuite.net/dash264/TestCases/1c/qualcomm/2/MultiRate.mpd";
    var context = new Dash.di.DashContext();
    var player = new MediaPlayer(context);
    player.startup();
    player.attachView(document.querySelector("#videoPlayer"));
    player.attachSource(url);
})();

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

<!doctype html>
<html>
    <head>
        <title>Dash.js Rocks</title>
    </head>
    <body>
        <div>
            <video id="videoPlayer" controls="true"></video>
        </div>
        <script src="yourPathToDash/dash.all.js"></script>
        <script>
            (function(){
                var url = "http://dash.edgesuite.net/akamai/test/caption_test/ElephantsDream/elephants_dream_480p_heaac5_1.mpd";
                var context = new Dash.di.DashContext();
                var player = new MediaPlayer(context);
                player.startup();
                player.attachView(document.querySelector("#videoPlayer"));
                player.attachSource(url);
            })();
        </script>
    </body>
</html>
