# Clappr Level Selector Plugin

## Usage

Add both Clappr and Level Selector plugin scripts to your HTML:

```html
<head>
  <script type="text/javascript" src="http://cdn.clappr.io/latest/clappr.min.js"></script>
  <script type="text/javascript" src="dist/level-selector.js"></script>
</head>
```

Then just add `LevelSelector` into the list of plugins of your player instance:

```javascript
var player = new Clappr.Player({
  source: "http://your.video/here.m3u8",
  plugins: [LevelSelector]
});
```

You can also customize the labels and title:

```javascript
var player = new Clappr.Player({
  source: "http://your.video/here.m3u8",
  plugins: [LevelSelector],
  levelSelectorConfig: {
    title: 'Quality',
    labels: {
        2: 'High', // 500kbps
        1: 'Med', // 240kbps
        0: 'Low', // 120kbps
    },
    labelCallback: function(playbackLevel, customLabel) {
        return customLabel + playbackLevel.level.height+'p'; // High 720p
    }
  },
});
```

And also transform available levels:

```javascript
var player = new Clappr.Player({
  // [...]
  levelSelectorConfig: {
    onLevelsAvailable: function(levels) {
      return levels.reverse(); // For example, reverse levels order
    },
  },
});
```

*Note: There is a minified version served through CDNs too:*
```html
<script type="text/javascript"
        src="//cdn.jsdelivr.net/gh/clappr/clappr-level-selector-plugin@latest/dist/level-selector.min.js"></script>
```

## Compatibility

All the playbacks that follow these rules:

* must trigger `PLAYBACK_LEVELS_AVAILABLE` with an ordered array of levels `[{id: 3, label: '500Kbps'}, {id: 4, label: '600Kpbs'}]`
* to have a property `levels`, initialized with `[]` and then after filled with the proper levels
* to have a property `currentLevel` (set/get), the level switch will happen when id (currentLevel) is changed  (`playback.currentLevel = id`)
* optionally, trigger events: `PLAYBACK_LEVEL_SWITCH_START` and `PLAYBACK_LEVEL_SWITCH_END`
* `id=-1` will be always the `Auto` level
