Does anyone know how to restrict the portion of the videocamera frame that zoom/skype/teams can see? Because I don’t have the ability to edit and recompile zoom/skype/teams, I can’t fix them to only use a portion of the camera field of view. Even if these programs had user controls for this, I don’t have any reason to trust them. I need a kernel solution. I’ve just spent an hour trying to find what Linux kernel controls for this there might be and how I might be able to tweak them from userspace. However, I failed to find any such controls. The ability to turn the camera off is well documented, but how to restrict the field of view (i.e., crop the frames that the applications see) seems to be either missing or well hidden.
Any suggestions? This is a clear privacy issue.
