# webOS plugin

The webOS plugin adds platform-specific behavior and functionality, including remote control functionality, for webOS. WebOS powers LG Smart TVs. Wowza provides [Smart TV help](/docs/wowza-flowplayer/smart-tv-sdk/getting-started/) to create webOS apps.

## Installation

Include the `webos` plugin next to the core player:


```html
<script src="//cdn.flowplayer.com/releases/native/3/stable/flowplayer.min.js"></script>
<script src="//cdn.flowplayer.com/releases/native/3/stable/plugins/webos.min.js"></script>
```

## App development

If you are creating an application for webOS, keep the following in mind (see below).

### Disable history API

In your `appinfo.json`, disable the back button on the remote control to use the history API:


```json
{
  "...": "...",
  "disableBackHistoryAPI": true
}
```

### Handle back button from player

The player will handle the back buttons internally. If you click the back button from your remote when the player is in a "neutral" state, the player will emit the `flowplayer.webos.events.EXIT_FULLSCREEN` event that you can handle in your app:


```js
player.on(flowplayer.webos.events.EXIT_FULLSCREEN, () => { // Exit from videoplayer requested
  window.webOS.platformBack() // shut down app
})
```
