I would like to replace the background behind in my webcam video feed with an image. However, that is not possible, as it requires a “green screen”, which I do not have. So, my idea is to use a virtual camera with a background image chosen by me and feed that into Zoom. Is that 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:
