# Video Playback

The platform WPE Browser supports MSE/EME for those interested in bringing a video playback solution to your app. The following open-source players have all been successfully deployed in apps:

- [HLS.js](https://github.com/video-dev/hls.js/)
- [DASH.js](https://github.com/Dash-Industry-Forum/dash.js)
- [Shaka](https://github.com/google/shaka-player)

Additionally, HLS and MPEG-DASH playback is available via the RDK's **Advanced Adaptive Media Player** (**AAMP)**. **AAMP** is an application which uses the GStreamer framework to present IP Video Streams.

You can learn more on the [RDK wiki](https://wiki.rdkcentral.com/display/RDK/Advanced+Adaptive+Media+Player).

To access the AAMP player in your app, you must replace the protocol of your content with `aamp` for http or `aamps` for https.

| Protocol | AAMP Replacement |
| --- | --- |
| `http://` | `aamp://` |
| `https://` | `aamps://` |

#### Example usage of AAMP in an HTML5 video tag:

```javascript
<body>
<video id="video"></video>
<script type="text/javascript">
var video = document.getElementById('video');
video.src = 'aamp:/hostname.port/path/resource.m3u8'
video.load();
video.play();
</script>
</body>
```

## Troubleshooting

When using HLS in the AAMP player, you must use the `EXT-X-STREAM-INF` tag.

Without that tag AAMP will try to use the hardware demuxer, which is buggy in Intel chipsets. Adding the tag will force AAMP to use a software demuxer which avoids the Intel hardware bug.

#### Video Player Sessions

The system browser only supports a single playback stream, multi-track assets are not supported. Additionally, orphaned player session invoke DRM and other failures. To avoid playback issues, please follow the recommendations below:

- Use single sessions for all playback.
- If multiple sessions are required, you must first destroy the previous player instance.

## DRM

The platform only supports Widevine 16 Service level 1 DRM.
