Is it feasible in Windows to enable (i.e. force) the use of a custom virtual background (via software) for any (all) videoconferencing applications that need to access to a webcam, for a webcam? (either screen-embedded front-facing, or external).
Or would that depend on the manufacturer of the hardware (e.g. laptop and webcam).
By virtual background I am referring to the ability of customizing the background on a video call so that people can see you as you look, but you can e.g. use a static or animated media for the rest of the background. E.g. this feature supported from Microsoft Teams, or this one from Zoom.
