Looks like BBC’s Brave project was the inspiration for this: https://github.com/bbc/brave (specifically the gst-WebRenderSrc) Brave is a real-time remote video/audio editing app. Looks neat.

Unrelated but wow, BBC has quite a bit of interesting and relevant open source projects. Simorgh, their react SSR framework, caught my eye “used on some of our biggest websites”. Encouraging for those looking to build out performance react/amp platforms https://github.com/bbc/simorgh
