and when i use your scipt on another console while the first run to test opencv :
import cv2
cap = cv2.VideoCapture(3)
while True:
ret, frame = cap.read()
cv2.imshow(“Arducam”, frame)
key = cv2.waitKey(1)
if key == ord(‘q’):
break
the response is :
VIDEOIO ERROR: V4L2: Pixel format of incoming image is unsupported by OpenCV
OpenCV Error: Assertion failed (size.width>0 && size.height>0) in imshow, file /build/opencv-L65chJ/opencv-3.2.0+dfsg/modules/highgui/src/window.cpp, line 304
Traceback (most recent call last):
File “test.py”, line 5, in

I don’t manage to make it work
Could you please explain me what i do wrong and how to solve it ?
thanks a lot
