dfttest2
A VapourSynth re-implementation of DFTTest.
This package serves as a meta-package providing:
- A high-level Python interface for
dfttest2. - Optional backend dependencies via extras to simplify installation.
Backends
GPU Backends
| Backend | Platform | Implementation Type |
|---|---|---|
nvrtc |
Windows, Linux (x86-64, aarch64) | JIT Compilation |
hiprtc |
Windows, Linux (x86-64) | JIT Compilation |
cufft |
Windows, Linux (x86-64, aarch64) | Library |
hipfft |
Windows, Linux (x86-64) | Library |
cpu |
Windows, Linux (x86-64), macOS (x86-64) | VCL |
gcc |
All Platforms | Compiler Vector Extensions |
Which one to use?
| Backend | Requirement |
|---|---|
| NVRTC | sbsize=16 and CUDA-enabled system |
| HIPRTC | sbsize=16 and HIP-enabled system |
| cuFFT | CUDA-enabled system |
| hipFFT | HIP-enabled system |
| CPU | sbsize=16 |
| GCC | sbsize=16 |
Approximate Speed: NVRTC == HIPRTC >> cuFFT > hipFFT > CPU == GCC
Installation
For example, to install the NVRTC and CPU backends:
pip install dfttest2[nvrtc,cpu]

Compilation
# additional options: -D ENABLE_CUDA=ON -D ENABLE_CPU=ON
cmake -S . -B build
cmake --build build
cmake --install build
If the vapoursynth library cannot be found by pkg-config, then the cmake variable VS_INCLUDE_DIR should be set.
