Overview

This project allows you to download a YouTube video and play it in your terminal as ASCII art with synchronized audio. It leverages multithreading to process video frames efficiently, ensuring smooth playback at the proper frames per second (FPS). Skipping frames as needed if unable to keep up with just multithreading.

There is a bug that you have to press Ctrl+C twice to exit the program. when playing a video.

Features

• ASCII Art Video Playback: Watch YouTube videos in your terminal as ASCII art.
• Synchronized Audio: Enjoy the video's audio alongside the ASCII art.
• Customization Options: Adjust the ASCII art scale, characters, and colors.
• Demo Mode: Play a demo video to test the functionality.
• Multithreaded Processing: Utilize multiple threads for efficient video processing.
• Fullscreen Mode: Fit the ASCII art to your terminal size. (Default, use --fullscreen to disable)
• Colored ASCII Art: Enable colored ASCII art for a more vibrant experience. (Default, use --colors to disable)
• Display Pictures: Display pictures in the terminal as ASCII art. (Default, use --image_path to specify a file path or url to an image)
  • ex. python vtap.py --image_path 'https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png' --chars ' .:-=+*#%@'
  • or python vtap.py --image_path '~/Downloads/your_image.png' --chars ' .:-=+*#%@'

Prerequisites

Before you begin, ensure you have the following installed on your system:

• Python 3.12
• ffmpeg or ffplay (for audio playback)
• pip (Python package installer)

Required Python Packages

• pytube (for downloading YouTube videos)
• opencv-python (for video processing)
• numpy (for numerical operations)
• colorama (for colored ASCII art) - allows color on Windows

You can install the Python packages using:

pip install -r requirements.txt

Installation and Setup

Clone the Repository

git clone https://github.com/VinnyVanGogh/vtap.git

Install Dependencies

Navigate to the project directory and install the required packages:

cd vtap
pip install -r requirements.txt

Ensure that ffmpeg or ffplay is installed and accessible from your command line:

• On macOS with Homebrew:

  brew install ffmpeg
  

• On Ubuntu/Debian:

  sudo apt-get install ffmpeg
  

• On Windows:

  Download from ffmpeg.org and add it to your system PATH.

Usage

Command-Line Arguments

The script accepts several command-line arguments to customize the playback:

• --url: (Required) The YouTube video URL.
• --chars: Characters to use for ASCII art (default: ' .:-=+*#%@').
• --scale: Scale factor for ASCII art (e.g., 0.5 for half size; default: 1.0).
• --colors: Enable colored ASCII art.
• --fullscreen: Fit ASCII art to terminal size.
• --demo: Play a demo video. (Plays 'Dax - Eminem "Houdini" Remix One Take Video' with --chars '█▓▒░ ')
• --image_path: Display an image in the terminal as ASCII art. (e.g., --image_path 'https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png' or --image_path '~/Downloads/your_image.png')

Examples

Demo Mode:

python vtap.py --demo

Basic Usage:

python vtap.py --url 'https://www.youtube.com/watch?v=dQw4w9WgXcQ'

Custom Characters and Scaling:

python vtap.py --url 'https://www.youtube.com/watch?v=dQw4w9WgXcQ' --chars ' .:-=+*#%@' --scale 0.5

Enable Colored ASCII Art:

python vtap.py --url 'https://www.youtube.com/watch?v=dQw4w9WgXcQ' --colors

Fullscreen Mode:

python vtap.py --url 'https://www.youtube.com/watch?v=dQw4w9WgXcQ' --fullscreen

How It Works

1. Download Video:

   The script uses pytube to download the specified YouTube video in MP4 format with both audio and video streams.

2. Multithreaded Processing:

   • Frame Reading Thread: Reads video frames and queues them for processing.
   • Frame Processing Threads: Multiple threads convert frames to ASCII art in parallel.
   • Frame Display Thread: Displays the ASCII frames in the terminal at the correct FPS.
   • Audio Playback Thread: Plays the video's audio simultaneously using ffplay.

3. ASCII Art Generation:

   • Each video frame is resized according to the specified scale or terminal size.
   • Frames are converted to grayscale and mapped to ASCII characters based on pixel intensity.
   • Optionally, color information is added using ANSI escape codes.

4. Synchronized Playback:

   • The display thread ensures that frames are shown at intervals matching the video's FPS.
   • Audio playback is synchronized with the video frames for a cohesive experience.

Troubleshooting

Common Issues

• SSL Certificate Error when Downloading Videos:

  If you encounter an SSL error, you may need to install the necessary certificates. On macOS, run the Install Certificates.command script located in /Applications/Python 3.13/ or /opt/homebrew/bin/python3.12 replace 3.12 with your current version.

• Slow Performance:

  • Reduce the --scale factor to lower the resolution.
  • Use fewer characters in --chars.
  • Disable colors by omitting the --colors flag.

• Audio Not Playing:

  Ensure that ffmpeg or ffplay is correctly installed and accessible from your command line.
