Welcome folks today in this blog post we will be building a webcam video recorder in tkinter framework and save the video as mp4 file using opencv library. All the full source code of the application is shown below.
Get Started
In order to get started you need to install the below libraries using the pip command as shown below
pip install opencv-python
pip install uuid
After that you need to make an app.py file and copy paste the following code
app.py

import tkinter as tk from tkinter import filedialog import cv2 import datetime import uuid class VideoRecorderGUI: def __init__(self, master): self.master = master master.title("Video Recorder") self.output_path = "" # Create the GUI elements self.label = tk.Label(master, text="Select destination folder:") self.label.pack() self.destination_button = tk.Button(master, text="Select Folder", command=self.select_destination) self.destination_button.pack() self.record_button = tk.Button(master, text="Record", command=self.start_recording) self.record_button.pack() self.stop_button = tk.Button(master, text="Stop", command=self.stop_recording, state=tk.DISABLED) self.stop_button.pack() def select_destination(self): self.output_path = filedialog.askdirectory() def start_recording(self): # Generate a unique filename unique_id = str(uuid.uuid4()) current_datetime = datetime.datetime.now() filename = f"{current_datetime.strftime('%Y%m%d%H%M%S')}_{unique_id}.mp4" # Start recording using OpenCV self.cap = cv2.VideoCapture(0) self.out = cv2.VideoWriter(self.output_path + "/" + filename, cv2.VideoWriter_fourcc(*"mp4v"), 25, (640, 480)) self.record_button.config(state=tk.DISABLED) self.stop_button.config(state=tk.NORMAL) self.record() def record(self): # Record frames until stop button is pressed ret, frame = self.cap.read() if ret: self.out.write(frame) self.master.after(1, self.record) def stop_recording(self): # Stop recording self.cap.release() self.out.release() self.record_button.config(state=tk.NORMAL) self.stop_button.config(state=tk.DISABLED) if __name__ == '__main__': root = tk.Tk() app = VideoRecorderGUI(root) root.mainloop() |
As you can see we are importing all the required libraries at the top including opencv. And after that we have written the python class of VideoRecorder in which we have declared all the methods to record the webcam and stop the recording and also select the output directory where all the files will be stored. And lastly we are creating a new object of that class and starting the application.
