VideoEncoder FFmpeg Wrapper

A sleek, high-performance video encoding GUI built with Rust and Slint. This tool provides a modern interface for batch converting videos using FFmpeg with a focus on HEVC (H.265) encoding.

Key Features

• Modern Apple-style Light Theme: A clean and premium interface designed for clarity and ease of use.
• Native Windows Drag & Drop: Seamlessly add files and folders by dragging them into the app window (implemented via low-level WndProc subclassing for maximum compatibility).
• HEVC (H.265) Optimization: Default configurations tailored for high-quality, low-size H.265 encoding.
• Detailed Progress Tracking: Real-time parsing of FFmpeg logs to show per-file percentage, encoding speed (x speed), and live bitrate.
• Batch Processing: Queue multiple files and folders for sequential encoding.
• Customizable Options: Easy adjustment of CRF (Quality), output suffix, and target directory.

Prerequisite

• FFmpeg: You need ffmpeg.exe installed on your system.
  • The app will automatically look for ffmpeg.exe in its own directory.
  • If not found, it will search your system PATH.
  • You can also manually select the path within the app.

Getting Started

📥 Download

You can download the latest version from the Releases Page.

Manual build

1. Clone the repository:

   git clone https://github.com/kirinonakar/VideoEncoder.git
   cd VideoEncoder

2. Ensure you have Rust installed.
3. Build and run the project:

   cargo run --release

Technical Implementation Highlights

• Window Subclassing: Uses windows-sys and SetWindowLongPtrW to hook into the Windows message loop (WM_DROPFILES), bypassing Slint's default D&D constraints to support administrator environments.
• Asynchronous Processing: Leverages tokio for non-blocking FFmpeg execution and log parsing.
• Declarative UI: Built using the Slint UI framework for a responsive and lightweight experience.
