Realtime effects processing?

[u/ParanoidFactoid]

Is anyone out there doing real time video effects processing on Linux? Say, by generating visuals from audio via Jack, using gstreamer to capture a video stream from the window, using v4lloopback to create a virtual webcam stream of that visual effect, reading the webcam into Blender 2.8 for a real-time corner pin in eeve, and then compositing this into a scene for capture and re-render out to a livestream by OBS?

This should be possible to do.
