working code for casting youtube

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

var mdns                  = require('mdns');

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

var sequence = [

var browser = mdns.createBrowser(mdns.tcp('googlecast'), {resolverSequence: sequence});

browser.on('serviceUp', function(service) {

//we dont know how to use features like stopping / pausing seeking the video on youtube



If this throws the error of Cannot find module 'q'

then do

npm install --save q


if it only shows youtube wallpaper paper and doesnt start any video then
open https://github.com/irfanhabib/youtube-castv2-client
this has updated communication protocals

and open node_modules .. open the folder for youtube-castv2-client then paste the files from github to update
this will make the video play
