import cv2

# Choose video1. Please choose the video node according your usecase.
cap = cv2.VideoCapture(1)
cap.set(cv2.CAP_PROP_FRAME_WIDTH, 3840)
cap.set(cv2.CAP_PROP_FRAME_HEIGHT, 2160)

# read one frame to start camera.

# AUTO: 1, Manual: 0
cap.set(cv2.CAP_PROP_AUTO_EXPOSURE, 0)
# If you turn off auto exposure, you need to set the gain once
cap.set(cv2.CAP_PROP_GAIN, 100)  

cv2.namedWindow("video", cv2.WINDOW_NORMAL)

    # Capture frame-by-frame
    ret, frame =
    # Display the resulting frame
    cv2.imshow('video', frame)
    if cv2.waitKey(1) & 0xFF == ord('q'):

# When everything done, release the capture
