VapourSynth filter for (shitty) bitdepth reduction.
It is based on ordered dithering but instead of a bayer matrix a (very bad) amogus pattern is used. Please don't use it, it's as shitty as the meme. I just needed an excuse to write something in Zig.
Don't.
amogus.Amogus(clip, depth[, range])
To make the pattern obvious you can set depth to something lower than 8. This plugin will then scale the lower bitdepth back to 8, since VapourSynth only supports clips with a bitdepth of 8 or more.
range can be used to force the output color range. Input color range is always derived from the frame properties.
You may need to add -I/usr/include to the commands below to find the VapourSynth headers.
I think, by default, Zig only looks for C headers in its own directories.
$ zig build-lib amogus.zig -dynamic -O ReleaseFast --strip
$ zig build-lib amogus.zig -dynamic -O ReleaseFast --strip -target x86_64-windows
