![]() You can change the fourcc codes, but you must check the output format ‘.avi’ for compatibility. NOTE: Higher fps provides better results, but leads to heavier files. screen_cap_writer: To write or save the screen capture to video format, we create a VideoWriter() with the parameters: output_file_name.avi, VideoWriter_fourcc – a 4 character code used to compress the frames, frames per second, (width, height) of the video frames.shape = img_np_arr.shape: To obtain the dimensions or shape of the array, which in turn will be the shape of the image.The array will contain pixel values corresponding to RGB values. img_np_arr = np.array(image): Convert the image to numpy arrays.It takes the parameters left, top, right and bottom (clockwise from left to remember). If you wish to record only a certain part of the screen or an app, use the parameter bbox(). image = ab(): Takes a screenshot of the entire screen.def record_screen(): Declare the function to initiate screen recording.#Stop and exit screen recording if user presses 'e' (You can put any letter) It will be displayed and also recorded in your video. If you choose to view the screen recording simultaneously, #OPTIONAL: To view your screen recording in a separate window, resize and use imshow() #OpenCV follows BGR and not RGB, hence we convertįinal_img = cv2.cvtColor(img_np_arr, cv2.COLOR_RGB2BGR) Height = int(shape * scale_by_percent / 100) Width = int(shape * scale_by_percent / 100) #Low scale_by_percent implies smaller window Use the aspect ratio scaling if you wish to view the screen recording simultaneously #To View the screen recording in a separate window (OPTIONAL) Screen_cap_writer = cv2.VideoWriter('screen_recorded.avi',cv2.VideoWriter_fourcc('M','J','P','G'), 50, (shape, shape)) Creating the screen recording function: def record_screen(): import numpy as np: Convert images to arrays and vice versaĢ.import cv2: To write the captured screen to a video, we use opencv.from PIL import ImageGrab: Take screenshot of the screen using ImageGrab.Hence we import it to make use of the widgets and define our application. from tkinter import *: We use Tkinter to build the user interface of the application.Importing libraries: #PythonGeeks Guide to create a simple Python screen recorder Please download the source code of python screen recorder: Screen Recorder Python Code Project File Structure:īelow is the flow of the Python Screen Recorder project.Ģ. Pillow pip install pillow Download Python Screen Recorder Code: We can use pip to install the other packages as follows: Sudo apt-get install python3-tkinter, for linux users and windows users can reinstall python or follow the steps given in Tkinter installation on windows. If not, you can install it using the command If it does not show any error, the package is available. The modules necessary are opencv, tkinter and pillow. Hence understanding the syntactic meaning should suffice. ![]() The project is an introduction to Pillow and OpenCV. Here, we create a simple screen recorder using tkinter and opencv. ![]() Let us make Python Screen Recorder Project. ![]() Now the advantages are plenty quality of the recording, less hassle and you can record it again at ease. A screen recorder records the contents or anything visible on the screen and saves it for later use. So what is the best alternative? A Screen Recorder. This is attributed to the quality and shakiness observed whilst recording. To record our screen for presentation, we cannot rely on cameras. ![]()
