This is an example how to play video on Jupyter using OpenCV and IPythone

cv2-video-ipython-jupyter.py

import numpy as np
import cv2
from IPython.display import display, Image
import time

video_path = "./HowDeepIsYourLove.mp4"

video = cv2.VideoCapture(video_path)
display_handle=display(None, display_id=True)
kernel = np.ones((5,5),np.float32)/25

try:
    while True:
        start = time.time()
        _, frame = video.read()
        # frame = cv2.flip(frame, 1) # if your camera reverses your image
        frame = cv2.filter2D(frame,-1,kernel)
        _, frame = cv2.imencode('.jpeg', frame)
        end = time.time()
        fps = 1/(end-start)
        display_handle.update(Image(data=frame.tobytes()))
except KeyboardInterrupt:
    pass
finally:
    video.release()
    display_handle.update(None)
