See Demo Video

Does not involve Mingw at all!

2. Install the pacman packages is not already have: base-devel, yasm, git
3. Close MSYS2
4. Starts VC201X x86/x64 command prompt, run msys2_shell.bat to launch MSYS2
5. Download FFmpeg, L-SMASH and L-SMASH Works source files
6. Build FFmpeg with configure options: --toolchain=msvc --enable-avresample
7. Check if lib*.a are produced
8. Open L-SMASH VS-solution file
9. Change build type from DLL to Static LIB
10. Uncheck project dependency on DLLexportgen
11. build L-SMASH (The RELEASE or DEBUG configuration)
12. Check liblsmash.lib is produced
13. Open Avisynth solution file
14. C/C++ > Code generation > Change /MD to /MT
15. Set Additional Include Path and Additional Library Path
16. Modify exlib.cpp:
17. remove/disable first two #pragma which are Mingw specific
18. change liblsmash.a to liblsmash.lib
