To play media on a Chromecast, you must first discover the device (e.g., using mdns), connect a new Client instance to the device's host, and then launch the DefaultMediaReceiver application. Once launched, you receive a player object which you can use to load media and control playback via methods like seek.
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 with the proper contentType.
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);
// Seek to 2 minutes after 15 seconds playing.
setTimeout(function() {
player.seek(2*60, function(err, status) {
//
});
}, 15000);
});
});
});
client.on('error', function(err) {
console.log('Error: %s', err.message);
client.close();
});
}
