## Getting Started

Download [videojs-contrib-dash](https://github.com/videojs/videojs-contrib-dash/releases). Include it in your web page along with video.js:

```html
<video id=example-video width=600 height=300 class="video-js vjs-default-skin" controls>
  <source
     src="https://example.com/dash.mpd"
     type="application/dash+xml">
</video>
<script src="video.js"></script>

<!-- videojs-contrib-dash stylesheet -->
<link rel="stylesheet" href="videojs-contrib-dash.css"></link>
<!-- videojs-contrib-dash script -->
<script src="videojs-contrib-dash.min.js"></script>

<script>
var player = videojs('example-video');
player.play();
</script>
```

Note that `videojs-contrib-dash` contains the code of Dash.js, so there is no need to load it separately.

Checkout our [live example](http://videojs.github.io/videojs-contrib-dash/) if you're having trouble.

## Protected Content

If the browser supports Encrypted Media Extensions and includes a Content Decryption Module for one of the protection schemes in the dash manifest, video.js will be able to playback protected content.

For most protection schemes, the license server information (URL &amp; init data) is included inside the manifest. The notable exception to this is Widevine-Modular (WV). To playback WV content, you must provide the URL to a Widevine license server proxy.

For this purpose, videojs-contrib-dash adds support for a "keySystemOptions" array to the object when using the `player.src()` function:

```javascript
player.src({
  src: 'http://example.com/my/manifest.mpd',
  type: 'application/dash+xml',
  keySystemOptions: [
    {
      name: 'com.widevine.alpha',
      options: {
        licenseUrl: 'http://m.widevine.com/proxy'
      }
    }
  ]
});
```

### Running Tests

- In a specific browser: `npm run test:chrome`, `npm run test:firefox`, etc.
- While development server is running, navigate to [`http://localhost:9999/test/`](http://localhost:9999/test/) (_note:_ port may vary, check console output)
