IIRC (see the "Reduced Screenshot" here: https://www.cpmspectrepi.uk/raspberry_p ... er_cameras )My camera works and displays properly when i use the command "libcamera-hello --qt-preview" but when i run it normally like "libcamera-hello" it doesn't work, i tried to use the camera in a face detection project but the camera output using cv2 is only black, does anyone know how do i fix this?
the --qt-preview option is (was) only "necessary" when using a (Real)VNC connected "display". So are you doing that or using a (physically) connected display? If the latter is that via a HDMI connection or another method/type?
