MSYS2 is simple to install, it uses a win32 port to install packages that is what I use to compile ffmpeg (among other libs). ffmpeg is also compiled and available with pacman : https://packages.msys2.org/package/mingw-w64-x86_64-ffmpeg > I suspect the "ffmpeg docs" (not sure what exactly you mean with it) were > written before wsl existed. > > But given our exchange so far, I wasn't extremely surprised that you > did not want to follow what I suggested. > > If you absolutely want to cross-compile from a Linux box for Windows, > this also works fine but I always only saw disadvantages.

Don't worry: I wrote the above (incorrectly) assuming that you want a Windows binary, that you can build on Windows (at least in theory) and that you assumed cross-compilation from Linux is necessary (as it was once upon a time).

If you want to compile for Windows, install wsl (wsl2 does not work here, wsl works fine). Then decide if you want to use msvc, clang or gcc for compilation. For gcc, there is an Ubuntu incantation to install the Windows toolchain. While this is not necessarily a cross-compilation, I suspect using the configure option "cross-prefix" is easiest. For msvc / clang, you do not need the whole Visual Studio, only the Build Tools for Visual Studio are needed. For clang and msvc, use the configure option "toolchain=msvc" In both cases, you don't need a cross compilation, just tell the configure script that your host os is win32.
