Documentation for the master branch with all features enabled
A safe wrapper for VapourSynth, written in Rust.
The primary goal is safety (that is, safe Rust code should not trigger undefined behavior), and secondary goals include performance and ease of use.
Most of the VapourSynth API is covered. It's possible to evaluate .vpy scripts, access their properties and output, retrieve frames. A notable exception is API for creating VapourSynth filters, which will come out next.
For an example usage see examples/vspipe.rs, a complete reimplementation of VapourSynth's vspipe in safe Rust utilizing this crate.
Raw bindings to VapourSynth.
Right now the x8664 and i686 Unix and x8664 Windows targets are supported.
All VapourSynth and VSScript API versions starting with 3.0 are supported. By default the crates use the 3.0 feature set. To enable higher API version support, enable one of the following Cargo features:
vapoursynth-api-31 for VapourSynth API 3.1vapoursynth-api-32 for VapourSynth API 3.2vapoursynth-api-33 for VapourSynth API 3.3vapoursynth-api-34 for VapourSynth API 3.4vapoursynth-api-35 for VapourSynth API 3.5vsscript-api-31 for VSScript API 3.1vsscript-api-32 for VSScript API 3.2To enable linking to VapourSynth or VSScript functions (currently required to do anything useful), enable the following Cargo features:
vapoursynth-functions for VapourSynth functions (getVapourSynthAPI())vsscript-functions for VSScript functions (vsscript_*())Make sure you have the corresponding libraries available if you enable the linking features. You can use the VAPOURSYNTH_LIB_DIR environment variable to specify a custom directory with the library files.
On Windows the easiest way is to install 64-bit Python, then use the VapourSynth installer (make sure the VapourSynth SDK is checked) and set VAPOURSYNTH_LIB_DIR to C:\Program Files (x86)\VapourSynth\sdk\lib64.
