Issues building ffmpeg on Windows [closed]

I have to use ffmpeg in our c++ Windows project. I have Visual Studio 2017.
For this I have to use ffmpeg-cpp.
ffmpeg-cpp is dependent on ffmpeg.

To build ffmpeg I am following instructions in https://ffmpeg.org/platform.html#Windows.
I installed MSYS2 MINGW64 using installer msys2-x86_64-20240113.exe.

But I am not seeing files like msys_shell.bat or mingw64_shell.bat or mingw32_shell.bat.

How do I get these files?

Also if I run commands like pacman -S make pkgconf diffutils I get this error:

error: failed retrieving file ‘pkgconf-2.1.0-1-x86_64.pkg.tar.zst’ from mirror.iscas.ac.cn : SSL certificate problem: self-signed certificate in certificate chain

How to resolve this certificate issue?

  • “I am not seeing files” In MSYS2 installation directory, of course. In C:\msys64.
