Answer 1

According to https://docs.opencv.org/master/db/d5c/tutorial_py_bg_subtraction.html You should use cv.bgsegm.createBackgroundSubtractorMOG()

I tested it on 3.4.0-dev and it worked.

Example Code:

import numpy as np
import cv2 as cv
cap = cv.VideoCapture('vtest.avi')
fgbg = cv.bgsegm.createBackgroundSubtractorMOG()
while(1):
    ret, frame = cap.read()
    fgmask = fgbg.apply(frame)
    cv.imshow('frame',fgmask)
    k = cv.waitKey(30) & 0xff
    if k == 27:
        break
cap.release()
cv.destroyAllWindows()
