Yes, I ended up using the prebuilt via mingw libs from Zeranoe after a few weeks of failing to get stable results from a VS compile. 

I notice that Google has a ffmpeg visual studio compiling guide I’ve not seen before as a new first search result. (https://pracucci.com/compile-ffmpeg-on-windows-with-visual-studio-compiler.html) So I’ll give that a try, as being able to step-wise debug my efforts would be significantly better than the endless web research I’m doing now (as I try to find references to success with the recent libavcodec api.)

So, to this day, there is no self contained Visual Studio project, not requiring MSYS2 or YASM, one can assemble or download that compiles and builds ffmpeg? I am asking here because the large volume of older ffmpeg news makes finding such information very time consuming, if not fruitless.
