Python OpenCV - How to removing window border and title

Question

I'm trying to 1) create a frameless window and 2) be able to resize the window to original or a set width/height

I've tried the fullscreen setting but only get a fullsized window. Python OpenCV - remove title bar, toolbar, and status bar

videoFile = "./videos/screen_sav1_lr2.mp4"
videoWindowName = "VideoWindow"
playbackRate = 30

videoCapture = cv2.VideoCapture(videoFile)
if not videoCapture.isOpened():
    print("Error: Could not open video.")
    exit()

cv2.namedWindow(videoWindowName, cv2.WND_PROP_FULLSCREEN)
cv2.setWindowProperty(videoWindowName, cv2.WND_PROP_FULLSCREEN, cv2.WINDOW_FULLSCREEN)

I've also tried

cv2.namedWindow(videoWindowName, flags=cv2.WINDOW_GUI_NORMAL)

How do I maintain the original size or resize it as borderless? Thank you in advance.

OpenCV doesn't provide this functionality, you'll have to use some other GUI frameworks. Here's a thread with few options
