You can do that with a v4l loopback driver. I set his up on my laptop
where Teams could be configured to see the virtual webcam. The pipe line
when something like this:
webcam -> ffmpeg -> v4l loopback -> Teams.
replace ffmpeg with any applicaton that supports processing video. You
could probably insert OBS into that slot or just run a custom ffmpeg
command to do whatever you want.

Given the amount of memory and compute time it takes to do the background
image filtering to get the Virtual Background, I would love to have a
"Virtual Background box" Which I plugged my Video camera into, and which
output another adulterated stream with real-time adjustment of the stream,
so that I have a clean video stream without the items I don't want and with
the added items that I do want... IE, a clean image with a virtual
background, but without beating up my laptop.
I wonder what it would take to build one of these boxes.

Chroma-keying and other post-processing effects are always implemented
by the application used to process/encode video. In the case of video
chat applications, the client application is responsible for these
features.

There seems to be several tools that will place a background on a
chroma-green screen using chroma-key. If you have used this with a Zoom
meeting what software did you find worked best? I'll be connecting via
zoom-linux if that makes a difference.
TIA,
