How do you convert an entire directory with ffmpeg?

Question

How do you convert an entire directory/folder with ffmpeg via command line or with a batch script?

Answer 1

windows:

@echo off
for /r %%d in (*.wav) do (
    ffmpeg -i "%%~nd%%~xd" -codec:a libmp3lame -c:v copy -qscale:a 2 "%

%~nd.2.mp3"
)

this is variable bitrate of quality 2, you can set it to 0 if you want but unless you have a really good speaker system it's worthless imo
