#macOS developers: is there a way to get a *raw*, unprocessed video stream for just getting the pixels out of a camera? No Center Stage, no Reactions, no background replacement, and no interaction from the user to allow enabling any of that. Like if I wanted to set up a telescope for astrophotography, weather monitoring, security surveillance, or literally any use case which isn't "pointing the camera at my face for a video call". Is AVFoundation too high-level for this?
