I am looking for a solution to horizontally (or vertically) mirror/flip the webcam image (not rotate) on MacOS on the hardware or driver level. The ultimate goal is to use a mirrored video stream in Webex, Zoom, or Skype.
I have seen solutions involving virtual cameras (e.g., OBS, Logitech Capture), which work, but this requires additional software and processes to run in parallel.
I am looking for a solution that works on the OS, driver, or hardware level to flip the image. The solution could be a specific webcam having a driver that allows flipping the webcam or an option on MacOs that I have not found.
Unfortunately, the Logitech cameras I have and their companion software (Camera Settings) only allow for adjustments of brightness, zoom, etc. but not for flipping the image.
Update to provide additional clarification on the use case: The background is that my webcam points first at a mirror -- hence, I need to flip the video screen to "undo the mirroring".
Under Windows, the device driver ("device properties") for many Logitech webcams offers the "orientation" option, allowing to flip the image horizontally or vertically. I am looking for a similar option under MacOS -- or for another webcam offering this option.
Any suggestions, ideas, or experiences are very welcome!
