Remember camera configuration across runs
My webcam has pretty severe colour problems which result in me looking like I've been left baking in the summer sun. The webcam is mounted inside the frame of the monitor, and folds back inside the monitor.
When the camera is folded back, the camera is disconnected from USB, and will be reset when taken back out.
Using qv4l2, I could change the configuration of the camera:
Similarly to how Pipewire remembers the volume and configuration of sound devices, it should remember the selected settings for webcams, so that settings that aren't touched by applications, or unavailable to them, gets restored.
