mpd parser

Package Exports

  • mpd-parser
  • mpd-parser/dist/mpd-parser.cjs.js
  • mpd-parser/dist/mpd-parser.es.js
  • mpd-parser/package.json

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (mpd-parser) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Installation

npm install --save mpd-parser

Usage

// get your manifest in whatever way works best
// for example, by reading the file from the filesystem in node
// or using fetch in a browser like so:

const manifestUri = 'https://example.com/dash.xml';
const res = await fetch(manifestUri);
const manifest = await res.text();

// A callback function to handle events like errors or warnings
const eventHandler = ({ type, message }) => console.log(`${type}: ${message}`);

var parsedManifest = mpdParser.parse(manifest, { manifestUri, eventHandler });

If dealing with a live stream, then on subsequent calls to parse, the previously parsed manifest object should be provided as an option to parse using the previousManifest option:

const newParsedManifest = mpdParser.parse(
  manifest,
  // parsedManifest comes from the prior example
  { manifestUri, previousManifest: parsedManifest }
);

Parsed Output

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

Manifest {
  allowCache: boolean,
  contentSteering: {
    defaultServiceLocation: string,
    proxyServerURL: string,
    queryBeforeStart: boolean,
    serverURL: string
  },
  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.

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

Browserify

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

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

var parsedManifest = mpdParser.parse(manifest, { manifestUri });

With ES6:

import { parse } from 'mpd-parser';

const parsedManifest = parse(manifest, { manifestUri });

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:

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