Streaming online content to a Chromecast is fast and easy, but what if you have local files on your desktop that you want to get on the big screen? There are a few niche apps out there that will serve, but one of the biggest media players, VLC, is working on built-in support for Google’s Chromecast. Recently the nightly build servers started pumping out early, unstable builds of VLC with Chromecast support, so I gave it a try.

You won’t find the familiar “cast” button that you see in many apps in this VLC build. Instead, the “Tools” menu has a new option called “Render Output”—this screen is for playing media on something other than the computer screen in front of you. It will detect and display Chromecasts on your local network, and the detection process seems to work great. You just pick the device you want to use and hit “OK.”

If you’re playing media you’ll need to stop it, and then once you hit play the casting process should start. I got an “unknown certificate” error at first, but, after accepting it, the usual Chromecast stuff started to happen. My TV turned on and switched to the right input. A Chromecast logo appeared, the loading bar popped up—and then it failed.
