I just installed opencv 3-dev. I then ran a simple code of a normal video capture which outputs the video taken from the webcam. But as soon as the program window opens the video freezes. It sometimes runs and sometimes hangs. I currently have found no solution. My code is as follows

import numpy as np import cv2 cap = cv2.VideoCapture(0) while(True): # Capture frame-by-frame ret, frame = cap.read() # Our operations on the frame come here gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY) # Display the resulting frame cv2.imshow('frame',frame) if cv2.waitKey(1) & 0xFF == ord('q'): break

When everything done, release the capture

cap.release() cv2.destroyAllWindows()

This is the code! I hope you help me! Thanks in advance!! :)
