Is there a way to stream augmented reality from a webcam and greenscreen?

I might want to twitch stream me developing a level in unreal editor in VR… and stream from a webcam with a greenscreen… for example…

What would be the best way to do this with unreal?
Would this work? https://liv.tv/

Yes is doable, I’mn developing something similar for a customer at the moment.

If you’re interested in a custom solution, feel free to contact me

I was actually wondering if it was doable in the editor while working… not for a game or product.
