Title
Body
I have this code trying to capture a frame from my webcam on raspberry pi, and saving it as an image. I use opencv 2, but I get strange errors when I run the code.. import time import sys from subprocess import call import cv2 cam = cv2.VideoCapture() while True: cam.open(-1) image = cam.read() cv2.imwrite("current.jpeg",image) time.sleep(10); This is what the program returns: VIDIOC_QUERYMENU: Invalid argument VIDIOC_QUERYMENU: Invalid argument VIDIOC_QUERYMENU: Invalid argument VIDIOC_QUERYMENU: Invalid argument VIDIOC_QUERYMENU: Invalid argument VIDIOC_QUERYMENU: Invalid argument VIDIOC_QUERYMENU: Invalid argument Traceback (most recent call last): File "kvamskogen.py", line 18, in <module> cv2.imwrite("current.jpeg",image) TypeError: <unknown> is not a numpy array What is wrong here?
