vapoursynth-julek-plugin is a collection of some new filters and some already known ones that I am implementing here to have more performance.

Please visit the wiki for more details.

Building:

Requirements:
    - Git
    - C++17 compiler
    - CMake >= 3.23

Linux:

git clone --recurse-submodules https://github.com/dnjulek/vapoursynth-julek-plugin

cd vapoursynth-julek-plugin/thirdparty

mkdir libjxl_build
cd libjxl_build

cmake -C ../libjxl_cache.cmake -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_COMPILER=clang -G Ninja ../libjxl

cmake --build .
cmake --install .

cd ../..

cmake -B build -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_BUILD_TYPE=Release -G Ninja

cmake --build build
sudo cmake --install build

I recommend compiling with clang or you may have problems with libjxl, if you want to try compiling with gcc you may need to add this to the second cmake command:
-DCMAKE_C_FLAGS=fPIC -DCMAKE_CXX_FLAGS=-fPIC

Windows:

Open the Visual Studio 2022 Developer PowerShell and use cd to the folder you downloaded the repository.

cd vapoursynth-julek-plugin/thirdparty

mkdir libjxl_build
cd libjxl_build

cmake -C ../libjxl_cache.cmake -G Ninja ../libjxl

cmake --build .
cmake --install .

cd ../..

cmake -B build -DCMAKE_BUILD_TYPE=Release -DVS_INCLUDE_DIR="C:/Program Files/VapourSynth/sdk/include/vapoursynth" -G Ninja

cmake --build build
