The library has a problem in dealing with Qt objects when it tries to move from a thread to another, which causes a crash with an exit code (139).
here is the code which fails at cv2.imshow('frame',gray):
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',gray) if cv2.waitKey(1) & 0xFF == ord('q'): break # When everything done, release the capture cap.release() cv2.destroyAllWindows()
and this is the output of the code:
QObject::moveToThread: Current thread (0x19a67b0) is not the object's thread (0x1a497b0).
Cannot move to target thread (0x19a67b0)
