How to install (or enable) ffmpeg in XAMPP that is installed on windows

I do scripting in my PC on XAMPP localhost. I need to use ffmpeg but I can not install or enable it on xampp V3.3. I tried many and many and many ways but believe me no one of them worked for me. I read and followed all of old similar questions but either not working or the packages could not be found. By the way I can not find .dll file to download that are mentioned in most answers. I really need help.
I use windows 10.
