f I write: cap = cv2.VideoCapture(0), my code works properly. but whenever I write cap = cv2.VideoCapture('C:\Users\Anjali\Documents\Python_Files\Video_tracking\slow.mp4'), it does't work.
Below is my code:
import cv2 import numpy as np
cap = cv2.VideoCapture('C:\Users\Anjali\Documents\Python_Files\Video_tracking\slow.mp4')
while (True):
ret, frame = cap.read()
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
cv2.imshow('Frame', frame)
if cv2.waitKey(1) & 0xFF == ord('q'): break
cap.release() cv2.destroyAllWindows()
It gives the following error, please help me in this: cv2.imshow('Frame', frame) error: ........\opencv\modules\highgui\src\window.cpp:261: error: (-215) size.width>0 && size.height>0 in function cv::imshow
