To cast a video from your computer to a TV, you only need to open a file on Chrome, click the Cast icon and choose your device. Or, you can install a third-party app or extension like Videostream, which can play almost any video format. Not that hard, right? Google's Chrome team is making it much easier to beam videos from your PC, though. Chromium Evangelist François Beaufort has revealed that the team has rolled out a new feature to the beta channel that adds a "Cast file" option below "Cast tab" and "Cast desktop."
