DFTTest re-implemetation

dfttest2

A VapourSynth re-implementation of DFTTest.

This package serves as a meta-package providing:

1. A high-level Python interface for dfttest2.
2. 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]

DFTTest re-implemetation (CUDA and x86)

Usage

from dfttest2 import DFTTest
output = DFTTest(input)

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.
