A bad script for FFMPEG installation

install_ffmpeg.bat

@echo off
echo Downloading FFMPEG
:: Change the URL to the latest FFMPEG build
curl -o ffmpeg.zip -L https://github.com/BtbN/FFmpeg-Builds/releases/download/autobuild-2021-04-26-12-39/ffmpeg-n4.4-6-g7e9b9f24df-win64-gpl-shared-4.4.zip

echo Extracting FFMPEG
tar -xf ffmpeg.zip

echo Moving FFMPEG to 'C:\ffmpeg'

if exist "C:\ffmpeg\" (rmdir /s /q c:\ffmpeg\)
:: Following needs to also be changed, the folder will be named after the ZIP in most cases
MOVE %~dp0ffmpeg-n4.4-6-g7e9b9f24df-win64-gpl-shared-4.4 C:\ffmpeg

echo Adding FFMPEG to PATH

:: thanks to https://stackoverflow.com/a/45566845
for /f "usebackq tokens=2,*" %%A in (`reg query HKCU\Environment /v PATH`) do set my_user_path=%%B
echo ---
echo This might break your PATH, so here is your current USER PATH, make sure to copy and save it in case something breaks:
echo %my_user_path%
echo ---

setx PATH "C:\ffmpeg\bin;%my_user_path%"

echo Hopefully done!
