Vapoursynth on Mac (ARM), setup?

[Selur]

Can anyone in detail describe how to setup Vapoursynth on MacOS for ARM?

Is using brew the recommended way to install Vapoursynth?
Should one use vsrepo to install plugins?
(doesn't seem like brews Vapoursynth install comes with vsrepo)
Any step-by-step for n00bs on how to get this working?

Brew is the easiest way by far and as such probably what I'd recommend. Vsrepo has experimental support I haven't even tried myself so the rest (any plugin/editor not in brew) you'll have to compile manually.

Have fun

Thanks for the info.

I do a lot of encoding with Vapoursynth on Apple Silicon Macs. You can find some of the plugins I’ve ported (or just built) in this repository: https://github.com/yuygfgg/Macos_vapoursynth_plugins.

These plugins are built on an M2 Pro CPU, so they may not work on M1 (not sure), and they don’t use SVE on M4.

A few tips:

std.Expr is slow on non-x86 platforms; akarin.Expr (LLVM-based) performs better.
sse2neon.h and the Simde library can help port almost all SIMD code to ARM, which is crucial for certain plugins (e.g., BM3DCPU).
KNLM compiles and runs without errors or warnings, but the output is broken, so it’s better to use nlm_ispc.
vsmlrt’s ort_coreml sometimes crashes on large clips (≥1080p) and keeps generating files in a directory, so you’ll need to manually clean them up.

You may also want to translate SSE routines inside vapoursynth, but I modified the VS-C fork and found hardly any improvement and it's probably the same in upstream.

we need a new plug-in system that run in every architecture and platforms

but i don't think this is possible with one developer for rewriting code and complexity of this task

@yuygfgg: dependencies of the plugins in your repository seem to be broken (created an issue entry over @github)
=> got an answer on github.
(read https://github.com/yuygfgg/Macos_vap...flows/main.yml)

You can get a faster boxblur and bilateral by compiling vszip plugin, Zig can generate SIMD for ARM natively.

Does it work with zig 0.13.0 (this is the version homebrew offers) ?
( ran into that with zsmooth)

just download the executable from the site:
https://ziglang.org/download/

zig-macos-aarch64-0.14.0-dev.2293+6d781e095.tar.xz

And run this:

git clone https://github.com/dnjulek/vapoursynth-zip
cd ./vapoursynth-zip
PATH-TO/zig-macos-aarch64-0.14.0-dev.2293+6d781e095/zig build -Doptimize=ReleaseFast

vszip always uses the latest zig-master version

good to know. Should it also work with 0.13.0 ?
