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 to tag builds.

Quick Start

Download 'master' or latest tagged release, extract and open main folder dash.js/index.html in your web browser to view the main test file.

Install Dependencies

  1. install nodejs
  2. install grunt
    • npm install -g grunt-cli
  3. install grunt-template-jasmine-istanbul
    • npm install grunt-template-jasmine-istanbul --save-dev
  4. install some other dependencies:
    • npm install grunt-contrib-connect grunt-contrib-watch grunt-contrib-jshint grunt-contrib-uglify grunt-jsdoc-plugin

Build / Run tests:

grunt --config Gruntfile.js --force

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>
