After I select a video from QFileDialog at first cap.read return with frame but after 15-16 frames cap.read return false and output video is only first 1 second of the main video. Help pls.

while cap.isOpened():
    ret,frame = cap.read()
    ""some codes here""
    out.write(frame)
if cv2.waitKey(1) & 0xFF == ord('q'):
    break
cap.release()
cv2.destroyAllWindows()

I actually solve the problem. It was code independent. It looks like opencv dlls were missing from the python path. I pasted the dlls and problem solved.
