Subtitles and Cover

To include subtitles and a cover image, use an Object instead of a string in the play method:

var ChromecastAPI = require('chromecast-api')

var browser = new ChromecastAPI.Browser()

var media = {
  url : 'http://commondatastorage.googleapis.com/gtv-videos-bucket/big_buck_bunny_1080p.mp4',
  subtitles: [
    {
      language: 'en-US',
      url: 'https://raw.githubusercontent.com/alxhotel/chromecast-api/master/test/captions_styled.vtt',
      name: 'English',
    },
    {
      language: 'es-ES',
      url: 'https://raw.githubusercontent.com/alxhotel/chromecast-api/master/test/captions_styled_es.vtt',
      name: 'Spanish',
    }
  ],
  cover: {
    title: 'Big Bug Bunny',
    url: 'http://commondatastorage.googleapis.com/gtv-videos-bucket/sample/images/BigBuckBunny.jpg'
  },
  subtitles_style: {

  }
}

browser.on('deviceOn', function (device) {

  // Starting to play Big Buck Bunny exactly at second #0 with example subtitles and cover
  device.play(media, 0, function () {
    console.log('Playing in your chromecast')

      setTimeout(function () {
        device.subtitlesOff(function (err,status) {
          if (err) console.log('Subtitles off: ERROR')
            else console.log('Subtitles off: SUCCESS')
        })
      }, 20000)

      setTimeout(function () {
        device.changeSubtitles(1, function (err, status) {
          if (err) console.log("Subtitles restored and in spanish: ERROR")
          else console.log("Subtitles restored and in spanish: SUCCESS")
        })
      }, 25000)

      setTimeout(function () {
        device.pause(function () {
          console.log('Paused: SUCCESS')
        })
      }, 30000)

      setTimeout(function () {
        device.unpause(function () {
          console.log('Resumed: SUCCESS')
        })
      }, 40000)

      setTimeout(function () {

          if (err) console.log("Change to english subtitles: ERROR")
          else console.log("Change to english subtitles: SUCCESS")
        })
      }, 45000)

      setTimeout(function () {
        console.log('Increase subtitles size')
        device.changeSubtitlesSize(2, function (err, status) {
          if (err) console.log("Increase subtitles: ERROR")
          else console.log("Increase subtitles: SUCCESS")
        })
      }, 50000)

      setTimeout(function () {
        device.seek(10,function (err) {
          if (err) console.log('Seek forward: ERROR')
          else console.log('Seek forward: SUCCESS')
        })
