How do I access my webcam in Python?

Question

I might want to get to my webcam from Python.

I attempted utilizing the VideoCapture extension, yet that didn't function admirably for me, I needed to work around certain issues, for example, it's somewhat delayed with the resolutions >320x230, and once in a while, it returns None for no clear explanation.

I just want to know, Is there any better way to access the webcam through python.

Answer 1

OpenCV has a support for getting information from the webcam, and it accompanies Python wrappers as a matter of course, you additionally need to install the NumPy for the OpenCV Python segmentation (called cv2) to work. Starting in 2019, you can also install both of these libraries with pip: 

pip install numpy 

pip install opencv-python

Look at the below code:

import cv2

cv2.namedWindow("preview")

vc = cv2.VideoCapture(0)

if vc.isOpened(): # try to get the first frame

    rval, frame = vc.read()

else:

    rval = False

while rval:

    cv2.imshow("preview", frame)

    rval, frame = vc.read()

    key = cv2.waitKey(20)

    if key == 27: # exit on ESC

        break

cv2.destroyWindow("preview")
