I am trying to jump to a specific frame by setting the CV_CAP_PROP_POS_FRAMES property and then reading the frame like this:
CV_CAP_PROP_POS_FRAMES
cvSetCapturePropert
I've successfully used the following on OpenCV 3 / Python 3:
# Skip to 150 frame then read the 151th frame cap.set(cv2.CAP_PROP_POS_FRAMES, 150)) ret, frame = cap.read()
