Description
Expected behaviour
We are expecting to get FPS = 10, as we get with opencv-python 4.7.0.72
import cv2
cap = cv2.VideoCapture('C:\\data\\raw\\avd13_cam6_20221112190637_20221112195338.mp4')
print(cap.get(cv2.CAP_PROP_FPS))prints 10.0
Actual behaviour
When using the latest version of opencv-python 4.8.0.78, we get 25.
import cv2
cap = cv2.VideoCapture('C:\\data\\raw\\avd13_cam6_20221112190637_20221112195338.mp4')
