The Video Compressor application is built with Electron and relies on FFmpeg for video processing. This page covers all dependencies and their purposes.

​
Core dependencies

​
fluent-ffmpeg

Version: ^2.1.2 Fluent-ffmpeg is a Node.js wrapper for FFmpeg that provides a fluent API for video and audio processing. In this application, it handles all video compression operations.
The application uses fluent-ffmpeg to:
  • Process video files with compression settings
  • Monitor compression progress in real-time
  • Handle video encoding with bitrate control (-b:v 1000k)
  • Manage temporary file cleanup after processing
You can see the implementation in renderer.js:32-51 where ffmpeg is configured with output options and event handlers.

​
ffmpeg-static

Version: ^5.0.0 Provides a static FFmpeg binary for Node.js applications. This eliminates the need for users to install FFmpeg separately on their system.
The FFmpeg path is automatically configured in renderer.js:7 using ffmpeg.setFfmpegPath(ffmpegPath). This ensures the application works out of the box without manual FFmpeg installation.

​
Development dependencies

​
Electron

Version: ^25.0.0 Electron is the framework that enables building cross-platform desktop applications using web technologies (HTML, CSS, and JavaScript).
Electron v25.0.0 is specified as a development dependency because it’s bundled with the application during the build process.

​
Node.js built-in modules

The application also uses several Node.js core modules:
  • fs: File system operations for reading/writing video files
  • path: Path manipulation for cross-platform file paths
  • os: Operating system utilities, specifically for temporary directory access

​
Version compatibility

Ensure you’re using a compatible Node.js version with Electron 25.0.0. Electron 25 requires Node.js 18.x or higher.
  • Node.js: 18.x or higher
  • npm: 8.x or higher
To check your installed versions, run:
node --version
npm --version

​
Installation

Install all dependencies with: 
npm install
This will install both production dependencies (ffmpeg-static and fluent-ffmpeg) and development dependencies (Electron).
