video is not oppening in jupyter notebook using opencv

Question

I have this function where I open a video and then return it's length and the counter, to check if the users watched the hole video. When I ran it in Visual Studio Code it worked fine, but in Jupyter is not opening the video, just returning the video_length and the counter. Can anyone help me solve this?

def play_video(path):
    cap = cv2.VideoCapture(path)
    player = MediaPlayer(path)
    video_length = int(cap.get(cv2.CAP_PROP_FRAME_COUNT))
    cv2.namedWindow("Frame", cv2.WND_PROP_FULLSCREEN)
    cv2.setWindowProperty("Frame",cv2.WND_PROP_FULLSCREEN ,cv2.WINDOW_FULLSCREEN)
    if (cap.isOpened()== False):
        print("Error opening video  file")
    counter = 0
    while(cap.isOpened()):
        ret, frame = cap.read()
        audio_frame, val = player.get_frame()
        if ret == True:
            cv2.imshow('Frame', frame)
            if cv2.waitKey(25) & 0xFF == ord('q'):
                break
            if val != 'eof' and audio_frame is not None:
                img, t = audio_frame
            else:
                break
            counter += 1
    cap.release()
    cv2.destroyAllWindows()
    return counter,video_length

output:

(0, 901)

I'm using Jupyter because I want to make an executable file for my script, so I'm going to convert it to .bat
