code :

import cv2
# Opens the inbuilt camera of laptop to capture video.
cap = cv2.VideoCapture(0)
i = 0

while(cap.isOpened()):
    ret, frame = cap.read()
    
    # This condition prevents from infinite looping
    # incase video ends.
    if ret == False:

CodePudding user response：

You need to write the path correctly.

out_path = "/home/fraction/Desktop/extract_webcam_frames/frames"
frame_name = 'Frame' str(i) '.jpg'
cv2.imwrite(os.path.join(out_path, frame_name), frame)
i  = 1
