Krevoxa ships the Windows ffmpeg 8.1.2 libraries built by the vcpkg "ffmpeg" port
(https://github.com/microsoft/vcpkg), not by a script of our own. They are LGPL: the port's default
feature set enables no GPL component, as the configure line below shows (--disable-libx264,
--disable-libx265, no --enable-gpl).

To reproduce them, install the port on a Windows machine:

    vcpkg install ffmpeg:x64-windows

The exact configure line baked into the avcodec dll we ship:
