I would like to replace the background behind in my webcam video feed

possible on Fedora?
You can use the v4l2loopback kernel module to create a virtual camera,
and use one of the many tools to send video to the virtual video
device. However, that will just send a video or image to the video
device, it won't get your webcam's picture and overlay it on top of
it. If you want that, you'll need to do what zoom is already trying
to do, which requires a static background (a green screen).
Thanks, Jonathan, for your clarification. I am now thinking about an
alternative: blurring the background. Skype can do that, but not Zoom
-- unfortunately.
Just one question, what do you mean by green screen? I use zoom on my
work laptop in Windows 10 showing static and animated backgrounds behind
the camera image so that people can't see anything in the room behind
me, and I didn't think there was anything special in my zoom configuration.
A picture is worth a thousand words, Steve:

Thanks Paul, now I understand. But what I don't understand is why you
are going to those lengths. As I said we use zoom for work video
conferencing and we all use static or animated images as backgrounds by
selecting the background we want in zooms configuration, which then
works fine. Why do you need to display something behind you to get it to
display a background image?
regards,
Steve
