> That's not true, that would mean that webcam video by default would flip any writing and make it unreadable. That is exactly what happens if I open Facetime on my Mac and hold something in the camera. To be a bit more precise: There are two streams generated. One is shown to yourself, and this one works like a mirror. The other one is shown to remote participants and this one is not flipped.
