shutter_speed TypeError

Dear Reader,

I would like to set the shutter speed below 1ms - for example 0.1ms (which i know is possible with the hq cam)

therefore a change in the source code is nessecary (solve TypeError). Are there any instructions on how to do that?

I would be infinitly grateful for help.

Traceback (most recent call last):
  File "/home/pi/kotzmichan.py", line 39, in <module>
    camera.shutter_speed = 0.5
  File "/usr/lib/python3/dist-packages/picamera/camera.py", line 2594, in _set_shutter_speed
    self._camera.control.params[mmal.MMAL_PARAMETER_SHUTTER_SPEED] = value
  File "/usr/lib/python3/dist-packages/picamera/mmalobj.py", line 1493, in __setitem__
    func(self._port, key, conv(value)),
ctypes.ArgumentError: argument 3: <class 'TypeError'>: wrong type

What would you recommend me?

Already stated in https://github.com/waveform80/picamera/issues/719#issuecomment-1138513164

It should be possible with libcamera.

libcamera-hello --shutter 100 should request a 100usec exposure time.

Any chance to set shutter speed below 1ms?

Not with the firmware stack (ie raspistill/vid or picamera).
