Screen Recorder using OpenCV Python


In this tutorial, we will learn how to create a screen recorder using the OpenCV and PyAutoGUI library.

PyAutoGUI is a cross-platform GUI automation module in Python used to programmatically control the mouse & keyboard.

Installing the modules

To install the OpenCV and PyAutoGUI module and some other associated dependencies, we can use the pip command:

pip install opencv-python

pip install PyAutoGUI

pip install numpy

The Code

import pyautogui
import cv2
import numpy as np
from datetime import datetime

resolution = pyautogui.size()

now =
timestamp = datetime.timestamp(now)

codec = cv2.VideoWriter_fourcc(*"XVID")
filename = str(int(timestamp))+".avi"

fps = 60.0

out = cv2.VideoWriter(filename, codec, fps, resolution)

cv2.namedWindow("Live", cv2.WINDOW_NORMAL)
cv2.resizeWindow("Live", 480, 270)

while True:
    img = pyautogui.screenshot()
    frame = np.array(img)
    frame = cv2.cvtColor(frame, cv2.COLOR_BGR2RGB)

    cv2.imshow("Live", frame)

    if cv2.waitKey(1) == ord('q'):
