Welcome to Video to ASCII Converter using Python Kivy and KivyMD #pythonkivy #kivy #python #kivymd

Welcome to this detailed tutorial on how to create a video to ASCII converter using Python, Kivy, and KivyMD. In this tutorial, we will walk you through the process of building a simple application that can convert a video file into ASCII art.

Step 1: Set up your environment

Before we start, make sure you have Python installed on your system. You can download Python from the official website and install it on your machine.

Next, install the Kivy and KivyMD libraries. You can do this by running the following commands in your terminal:

pip install kivy
pip install kivymd

Step 2: Create the main Python script

Create a new Python file (e.g., main.py) and open it in your favorite code editor. Now, let’s start by importing the necessary modules:

from kivy.app import App
from kivy.uix.boxlayout import BoxLayout
from kivy.uix.textinput import TextInput
from kivy.uix.button import Button

Next, we will create a class that represents our application. This class will contain the UI elements and the logic to convert the video into ASCII art:

class VideoToAsciiApp(App):
    def build(self):
        layout = BoxLayout(orientation='vertical')

        video_input = TextInput(hint_text='Enter video file path', multiline=False)
        convert_button = Button(text='Convert to ASCII')

        layout.add_widget(video_input)
        layout.add_widget(convert_button)

        return layout

if __name__ == '__main__':
    VideoToAsciiApp().run()

Step 3: Implement the conversion logic

Now, let’s add the logic to convert the video file into ASCII art. We will use OpenCV and numpy libraries to read the video frames and apply the ASCII conversion:

import numpy as np
import cv2

def convert_to_ascii(video_file_path):
    cap = cv2.VideoCapture(video_file_path)

    for i in range(1000):
        ret, frame = cap.read()
        gray = cv2.cvtColor(frame, cv2.COLOR_BGR2GRAY)
        ascii_chars = '@%#*+=-:. '
        ascii_image = ''

        for row in gray:
            for pixel in row:
                ascii_image += ascii_chars[pixel // 32]
            ascii_image += 'n'

        # Print or save the ASCII image here

    cap.release()

Step 4: Update the UI

Lastly, let’s update our VideoToAsciiApp class to call the convert_to_ascii function when the user clicks the ‘Convert to ASCII’ button:

class VideoToAsciiApp(App):
    def build(self):
        layout = BoxLayout(orientation='vertical')

        video_input = TextInput(hint_text='Enter video file path', multiline=False)
        convert_button = Button(text='Convert to ASCII')

        convert_button.bind(on_press=lambda instance: convert_to_ascii(video_input.text))

        layout.add_widget(video_input)
        layout.add_widget(convert_button)

        return layout

if __name__ == '__main__':
    VideoToAsciiApp().run()

Conclusion

Congratulations! You have successfully created a simple video to ASCII converter using Python, Kivy, and KivyMD. You can further enhance this application by adding more features like saving the ASCII art as an image file or adjusting the ASCII characters based on brightness levels.
