About:
frei0r is a lightweight, cross-platform framework for video effects that provides a standardized plugin API. It allows developers to create simple video filters and generators that can be integrated into various video editors and processing applications. Its main value is enabling interoperability and a modular approach to video effect development.
Key Features:
  • Minimalistic and easy-to-use plugin API
  • Cross-platform compatibility (Linux, macOS, Windows)
  • Broad integration in major video software (e.g., FFmpeg, GStreamer, Kdenlive)
  • C-based API for high performance and low overhead
Use Cases:
  • Developing custom video filters for open-source video editors
  • Integrating a standardized effects library into multimedia applications
  • Applying real-time video effects in live streaming pipelines
Alternatives:
  • FFmpeg filters – FFmpeg provides a vast built-in filter library, but frei0r offers a standardized plugin interface for extending functionality across different applications.
  • OpenGL Shading Language (GLSL) – GLSL offers direct GPU programming for graphics, whereas frei0r provides a higher-level, abstracted API specifically for 2D video processing.
