I want to convert my entire music library (in the current folder, I'd like to convert the subfolders too) to Opus using FFmpeg. The converted files should go to a folder in ~/Desktop/Opus and keep their hierarchy. I wrote the following command:



find . -name "*.mp3" -exec ffmpeg -i "./" "~/Desktop/Opus/.opus" ;


The problem is that it doesn't work. It seems to have problems parsing the embedded FFmpeg command, as it shows errors like this one for every file:

find [...] -exec will use the (relative) path to the found files. If you want to use -exec with the assumption that the found file is in the current directory, you want to instead use -execdir.
