YouTube has slowly been adding features to its live video streaming. Live video has become a big deal, with platforms also built by Twitter and Facebook. Instagram, a subsidiary of Facebook, is also adding a live video feature.
YouTube now is supporting 4K video live streaming, something that will be useful for gamers who stream videos. It allows you to watch these videos on 4K monitors and TVs, which are slowly becoming more prominent.
The 2016 Game Awards was a trial for the feature. You can watch it now at 2160p and at 60 FPS.
What else does it mean? For new 360 degree videos, they will also be streamable live in 4K. For Android TVs, YouTube has already supported 4K video on applicable devices, so this should work out of the box, assuming the Internet connection can handle it.
