Choose your weapon and then hit play to enjoy movie night.
It’s worth noting that if you already have popular open-source media player VLC installed on your computer, this boasts the ability to beam a wide variety of files to any Android TV or Chromecast in a few clicks.
Simply load up the video inside VLC as normal, but head to the Playback menu option at the top, then scroll down to Renderer. In the small sub-menu that loads, you should see any compatible Chromecast, Google Home or Android TV devices listed. Pick one and hit play.
