Re: [FFmpeg-devel] [RFC] New build system

Hey $list, not an FFmpeg developer, but I worked on the meson port and figured I could address some of the points that were made. Since the initial post I have also added support for compiling with Msys/MingW on Window now in addition to MSVC. ## Performance comparison A significant part of the
