Camera controls for Linux
It’s a standalone Python CLI and GUI (GTK, TK) to set the Camera controls in Linux. It can set the V4L2 controls and it is extendable with the non standard controls. Currently it has a Logitech extension (Led mode, led frequency), Kiyo Pro extension (HDR, HDR mode, FoV, AF mode, Save), Systemd extension (Save and restore controls with Systemd path+service).
