Dears,
I got running exampe
import numpy as np
import cv2
cap = cv2.VideoCapture('vtest.avi')
while(cap.isOpened()):
ret, frame = cap.read()
gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
cv2.imshow('frame',gray)
if cv2.waitKey(1) & 0xFF == ord('q'):
break
cap.release()
cv2.destroyAllWindows()
When video finishes I got error at Python console and freeze
Traceback (most recent call last):
File "<ipython-input-1-2cc765029316>", line 1, in <module>

gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
error: ..\..\..\modules\imgproc\src\color.cpp:3739: error: (-215) scn == 3 || scn == 4 in function cv::cvtColor
What correctly to stop video?
Best regards, Peter
