Low level VapourSynth bindings to Rust

This crate provides raw unsafe FFI bindings to the VapourSynth API. For a safe wrapper, see rustsynth.

Feature Flags

The bindings are conditionally compiled based on feature flags:

  • api-41 - Enables VapourSynth API version 4.1 headers (VS_USE_API_41)
  • vs-graph-api - Enables the experimental graph API (VS_GRAPH_API)
  • script-api-42 - Enables VSScript API 4.2 headers (VSSCRIPT_USE_API_42)
  • vapoursynth-functions - Links to the main VapourSynth functions library
  • vsscript-functions - Links to the VSScript functions library

Different feature combinations will expose different functions and types in the generated bindings.
