This is on Ubuntu 12.04 I'm trying to figure out how to get ffmpeg to do a batch conversion of FLACs to MP3, recursively. If I cd into a directory and use
for f in *.flac; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done
that works perfectly fine. However, when I try this, it doesn't work:
for f in "$(find . -type f -name *.flac)"; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done
It doesn't even throw up any useful errors (but here is the output anyway, no need to complain):
evilsoup@enchantment:~/Music/Jean Sibelius$ for f in "$(find . -type f -name *.flac)"; do ffmpeg -i "$f" -c:a libmp3lame -q:a 2 "${f/%flac/mp3}"; done

I've tested the find command on its own, and it works as expected, so the problem has to be something to do with the interaction between find and for.
I'm aware that I could do something with find's -exec option, but I can't find any way to do string substitution as I can with a bash for loop, and I'd rather not have a bunch of file.flac.mp3s to deal with, even if they could be fixed with a simple rename.
