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:

What am I doing wrong?
