This feature is currently only available in version 3.0 of VLC for Windows and Mac, so you’ll need a Windows PC or Mac and an up-to-date version of VLC to continue.

Oh, and of course you’ll need a Chromecast device, or an Android TV device like the NVIDIA SHIELD (because they can accept Chromecast-standard streams, too), or a television that uses Android TV as its software (like one of Sony’s newer TVs). The PC or Mac you’re using to stream needs to be on the same local network as your Chromecast device, wired or wireless.

How to Cast Video From VLC

• Once you’ve downloaded and installed the appropriate version of VLC, you can get started. First, ensure your Chromecast and your television are on.
• You won’t find a “Cast” icon in VLC—at least, not at the moment. To find your Chromecast, you’ll need to click Playback > Renderer > Scan. If your Chromecast already appears in the menu, click on it in the list.

• Open a video file in VLC and click the “Play” button. Use the Media > Open File menu or just drag and drop a video file from your file manager onto the VLC window.
• After you try to play the video, you’ll see an “Insecure site” prompt. Click “View certificate” to view your Chromecast’s security certificate.

Click “Accept Permanently” to accept your Chromecast’s certificate.

The video file should immediately begin playing on your Chromecast after you agree, with your Chromecast streaming the file from the VLC player on your computer. Use the controls in the VLC window to pause, fast forward, rewind, and otherwise control playback.

When you try streaming in the future, you’ll just need to use the Playback > Render menu to scan and connect. Afterwards, you can play video files without accepting the certificate prompt again.

Again, this feature is still in development. When I tested it on my PC and SHIELD, the video was playing back with a lot of missed frames and audio de-synced by about a second. At the time of writing, pretty much any other way to play back video would be better, for example, loading local media up on a flash drive and playing it back via a smart TV or set-top box.

Specifically, there’s an easy way to stream your computer’s desktop video to a Chromecast using Google Chrome’s built-in casting tool. To start it, open Chrome to any website, then click the Chromecast icon, or click the Menu button and click “cast.”

Select the drop-down menu next to “Cast to,” then change the source from the Chrome tab to “Cast Desktop.” Then select your Chromecast or Android TV device.

Once Chromecast is broadcasting the whole screen, just open VLC and play your video in fullscreen. Note that, because Chromecast’s video streaming protocol is focused on speed rather than quality, the video quality will be much lower than in the steps above.
