I couldn't find an installer so I made one myself.
One line install script:
curl https://raw.githubusercontent.com/Leo-Aqua/Windows-FFMPEG-installer/main/FFmpeg-insataller.bat -o %TEMP%/FFmpeg-insataller.bat -# && powershell Start-Process "%TEMP%\FFmpeg-insataller.bat" -Verb RunAs
I hope this makes yoour life easier
made with code i guess...
