## Installation

```sh
npm install --save mpd-parser
```

The npm installation is preferred, but Bower works, too.

```sh
bower install  --save mpd-parser
```

## Usage

```js
var manifest = [
  '<>',
  '<>',
].join('\n');

var parsedManifest = mpdParser.parse(manifest, manifestUrl);
```

### Parsed Output

The parser ouputs a plain javascript object with the following structure:

```js
Manifest {
  allowCache: boolean,
  endList: boolean,
  mediaSequence: number,
  discontinuitySequence: number,
  playlistType: string,
  playlists: [
    {
      attributes: {},
      Manifest
    }
  ],
  mediaGroups: {
    AUDIO: {
      'GROUP-ID': {
        default: boolean,
        autoselect: boolean,
        language: string,
        uri: string,
        instreamId: string,
        characteristics: string,
        forced: boolean
      }
    },
    VIDEO: {},
    'CLOSED-CAPTIONS': {},
    SUBTITLES: {}
  },
  dateTimeString: string,
  dateTimeObject: Date,
  targetDuration: number,
  totalDuration: number,
  discontinuityStarts: [number],
  segments: [
    {
      byterange: {
        length: number,
        offset: number
      },
      duration: number,
      attributes: {},
      discontinuity: number,
      uri: string,
      timeline: number,
      key: {
        method: string,
        uri: string,
        iv: string
      },
      map: {
        uri: string,
        byterange: {
          length: number,
          offset: number
        }
      },
      'cue-out': string,
      'cue-out-cont': string,
      'cue-in': string
    }
  ]
}
```

## Including the Parser

To include mpd-parser on your website or web application, use any of the following methods.

### `<script>` Tag

This is the simplest case. Get the script in whatever way you prefer and include it on your page.

```html
<script src="//path/to/mpd-parser.min.js"></script>
<script>
  var mpdParser = window['mpd-parser'];
  var parsedManifest = mpdParser.parse(manifest, manifestUrl);
</script>
```

### Browserify

When using with Browserify, install mpd-parser via npm and `require` the parser as you would any other module.

```js
var mpdParser = require('mpd-parser');

var parsedManifest = mpdParser.parse(manifest, manifestUrl);
```

With ES6:
```js
import { parse } from 'mpd-parser';

const parsedManifest = parse(manifest, manifestUrl);
```

### RequireJS/AMD

When using with RequireJS (or another AMD library), get the script in whatever way you prefer and `require` the parser as you normally would:

```js
require(['mpd-parser'], function(mpdParser) {
  var parsedManifest = mpdParser.parse(manifest, manifestUrl);
});
```
