FFMPEG issue — "[NULL @ 0x7fa48980e200] Unable to find a suitable output format — converting .m4a to .mp3












0















I am trying to convert a folder full of music to .mp3 -- see code:



#! /bin/bash
for i in *.m4a ; do
/users/.../itunesmedia/music/ffmpeg -i "$i"
-acodec libmp3lame $(basename “${i%.m4a}”).mp3 sleep 60
done

sudo chmod +x dothis.sh


It says it's an invalid argument.

  • “${i%.m4a}” --> I believe these should be regular double quotes.
