While Google's Chrome team has been busy working on VR web browsing, Opera decided to focus on solving one particular pain point: switching online videos between desktop browsers and VR headsets. Today, you can finally get a taste of Opera's solution via its Developer 49 build. Basically, as long as there's a VR headset plugged into your Windows, macOS or Linux PC, this Opera build will show a "Watch in VR" button at the top of any video -- be it a normal clip, a 180-degree video or the full 360 video. Just click the button and the same video will show up on your VR headset right away. It's as simple as that.
