We recently launched a Alpha version of our software that uses Jitsi as the main video conference platform.
The software creates a 3D Virtual TV News studio ( or a spaceship ), and put the users from jitsi side-by-side ( max. 4 users ). You can use your own Jitsi self hosted server, its fully compatible, you just need to change the URL on the ‘Nextfloor Room for Guests’ application.
If users uses Chromacam software (on Win10) as a main camera device the chromakey effect is applied on each user, so the background will be transparent.
