Guide to compiling Av1an on Windows.
Download vapoursynth r57 portable from https://github.com/vapoursynth/vapoursynth/releases it's a 7z file so you should have 7-zip installed
Get Msys2 from https://www.msys2.org/, click on "download the installer" & install it with everything
Close msys2
Open msys2 mingw x64
Commands
this updates msys2 packages, write Y when needed and press enter, it will close the window when it finishes so open msys mingw x64 again
- pacman -S cmake git nasm python3 mingw-w64-x86_64-gcc mingw-w64-x86_64-cmake base-devel mingw-w64-x86_64-ffmpeg mingw-w64-x86_64-rust mingw-w64-x86_64-lld mingw-w64-x86_64-clang mingw-w64-x86_64-make
this will install necessary stuff
Open VapourSynth32-Portable-R57.7z and copy all the libraries from \sdk\lib64 to C:\msys64\mingw64\lib
this downloads the Av1an source
this will take the shell to the Av1an folder
This is optional but if you want a bit more of performance,(i'm talking a small bit) go in explorer to C:\msys64\home"your username"\Av1an and open Cargo.toml and edit it with your text editor of choice, i used notepad++ and in the [profile.release] section change lto = "thin" to lto = "fat", i also added opt-level = 3 but that may not be necessary
- RUSTFLAGS="-C target-cpu=native" cargo build --release
#this compiles it with march native which gives a bit of performance
Profit, the executable should be created in C:\msys64\home"your username"\Av1an\target\release
