Sometimes the phone screen is too small for us to watch some videos, and Google Chromecast comes to the rescue to let you send videos from mobile to TV. There were big video sites, adding Chromecast feature to their features list, like YouTube and Vimeo, but Facebook was a notably absent to the date.
Facebook just added the possibility to cast the site videos on your TV. Instead of using the icon Cast (waves to the TV), Facebook has opted for a TV icon. You’ll find it in the button bar of the video player on Android.
Pressing the button a separate window will appear, now you will find Chromecast icon, and another button to switch between those options, opens. You must choose the device and then press connect to start playing.
