castv2-client

A Chromecast client based on the new (CASTV2) protocol

This module implements a Chromecast client over the new (CASTV2) protocol. A sender app for the DefaultMediaReceiver application is provided, as well as an Application base class and implementations of the basic protocols (see the controllers directory) that should make implementing custom senders a breeze.

This implementation tries to stay close and true to the protocol. For details about protocol internals please see https://github.com/thibauts/node-castv2.

Installation

$ npm install castv2-client

Examples

Launching a stream on the device :

var Client                = require('castv2-client').Client;
var DefaultMediaReceiver  = require('castv2-client').DefaultMediaReceiver;
var mdns                  = require('mdns');

var browser = mdns.createBrowser(mdns.tcp('googlecast'));

browser.on('serviceUp', function(service) {
  console.log('found device "%s" at %s:%d', service.name, service.addresses[0], service.port);
  ondeviceup(service.addresses[0]);
  browser.stop();
});

browser.start();

function ondeviceup(host) {

  var client = new Client();

  client.connect(host, function() {
    console.log('connected, launching app ...');

    client.launch(DefaultMediaReceiver, function(err, player) {
      var media = {
      	// Here you can plug an URL to any mp4, webm, mp3 or jpg file.
        contentId: 'http://commondatastorage.googleapis.com/gtv-videos-bucket/big_buck_bunny_1080p.mp4'
      };

      player.on('status', function(status) {
        console.log('status broadcast playerState=%s', status.playerState);
      });

      console.log('app "%s" launched, loading media %s ...', player.session.displayName, media.contentId);

      player.load(media, { autoplay: true }, function(err, status) {
        console.log('media loaded playerState=%s', status.playerState);
      });

    });
    
  });

  client.on('error', function(err) {
    console.log('Error: %s', err.message);
    client.close();
  });

}
