I notice you mentioned "gnter camera driver" — did you mean camera driver? Or perhaps a specific camera SDK (like V4L2, UVC, or a vendor-specific driver like for Intel RealSense, Basler, etc.)? gnter camera driver
(e.g., kernel V4L2 subdev), I’d need more specifics. Could you please provide the exact driver name or more details about the feature you want? Then I can give you working code or a development plan. import gi gi
