I assume it still functions normally while acting as a webcam (aka it's a general purpose computer with ssh etc.)

Would it be possible to insert ffmpeg in between the camera and the output to usb? It'd be fun to throw some weird post processing in there.

I'd want OBS running. I'd love to offload OBS from my computer to a Pi.

It'd be nice if there were some docs about how this works and how to hack it.

Key thing with tools like OBS is you want a dedicated CPU. It's not super-CPU hungry, but it can stall if your CPU is otherwise, erm, occupied.

OBS would really kill a Pi if you tried doing anything too complicated. It can do screen capture, and maybe a few simple scenes, but things like multiple sources/compositing are too taxing on the SoC right now.

But you can get it to run—see: https://obsproject.com/forum/threads/obs-raspberry-pi-build-...

I'm more than happy to step up in price/power. I'm not sure if a more expensive device would act as a webcam, though.

Use a CM4 as the guts to the camera and it wouldn't have a problem with any of that.
