Create python program with width and height from v4l2-ctl result.

import cv2
print(cv2.__version__)
width=640
height=480
flip=2
#camSet='nvarguscamerasrc sensor-id=0 ! video/x-raw(memory:NVMM), width=3264, height=2464, framerate=21/1,format=NV12 ! nvvidconv flip-method='+str(flip)+' ! video/x-raw, width='+str(width)+', height='+str(height)+', format=BGRx ! videoconvert ! video/x-raw, format=BGR ! appsink'
camSet ='v4l2src device=/dev/video0 ! video/x-raw,width='+str(width)+',height='+str(height)+',framerate=24/1 ! videoconvert ! appsink'
cam=cv2.VideoCapture(camSet)
while True:
    _, frame = cam.read()
    cv2.imshow('myCam',frame)
    cv2.moveWindow('myCam',0,0)
    if cv2.waitKey(1)==ord('q'):
        break
cam.release()
cv2.destroyAllWindows()
