Rustsynth is a comprehensive Rust wrapper for VapourSynth, a powerful video processing framework. This project demonstrates advanced systems programming skills by providing safe, idiomatic Rust bindings for a complex C++ library.
Key Features
- Memory Safety: Leverages Rust’s ownership system to prevent common video processing errors
- Performance: Zero-cost abstractions maintain VapourSynth’s high performance
- Type Safety: Strong typing prevents runtime errors in video filter chains
- Cross-platform: Works seamlessly across Windows, macOS, and Linux
Technical Highlights
- Large-scale systems project: Over 6,000 lines of production Rust code
- Complex FFI bindings: Safe wrappers around VapourSynth’s extensive C++ API surface
- Advanced memory management: Custom allocators and lifetime management for video frame data
- Multi-threaded processing: Thread-safe filter graph execution with work-stealing scheduling
- Custom build system: Sophisticated cargo integration with dynamic library detection
- Plugin architecture: Extensible filter system with dynamic loading capabilities
- rspipe implementation: Complete Rust reimplementation of VapourSynth’s vspipe CLI tool
Real-World Usage
Rustsynth enables high-performance VapourSynth plugin development:
- vs-frameblender-rs: A VapourSynth plugin written in Rust using SIMD intrinsics and rustsynth’s safe wrapper. Used in video processing workflows and tools for advanced frame blending operations. Written by me.
