I've been using https://github.com/allo-/virtual_webcam_background https://github.com/allo-/virtual_webcam_background There are many others similar to the above. They all basically work by using the v4l2loopback driver to create a loopback video device. Then you have the program consume video from the real webcam video device, apply a deep learning model that subtracts the background (leaving your face and torso) and replaces it with an image or video of your choice, and outputs the video to the loopback device. Then you configure your video conferencing software (zoom, teams, webex, whatever) to use the loopback device instead of the real one.
