we use your camera for a research project and encountered an issue:
The camera works, but we can not use the software zoom and focus.
We did everything exactly as described here: https://www.arducam.com/docs/cameras-for-raspberry-pi/ptz-camera/user-guide/
When we run:
pi@raspberrypi:~/new/PTZ-Camera-Controller/pyCode $ python2 AutofocusExample.py
It shows a picture for a second and then closes, without any options. Same for all other scripts in the Github repo.
When we run:
pi@raspberrypi:~/new/PTZ-Camera-Controller/pyCode $ python3 AutofocusExample.py
We get an error:
Traceback (most recent call last):
File “AutofocusExample.py”, line 25, in <module>
import cv2 #sudo apt-get install python-opencv
File “/usr/local/lib/python3.7/dist-packages/cv2/init.py”, line 3, in <module>
from .cv2 import *
ImportError: /usr/local/lib/python3.7/dist-packages/cv2/cv2.cpython-37m-arm-linux-gnueabihf.so: undefined symbol: __atomic_fetch_add_8
The same reproduces with all other scripts in the directory.
We believe our setup is correct:
pi@raspberrypi:~/PTZ-Camera-Controller/pyCode $ sudo apt-get install python-opencv

We use the latest hardware, a RaspberryPi 4 with 4GB Ram and Rasbian Full. We are university researchers and have already tried googling the error message etc, but to no avail.
Can you please help us and tell us where it went wrong.”
