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

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>
