I'm working on a web based Youtube -> MP3 Converter. Would anyone use it? I know that such services already exist, but a lot of them have many-a-popup, can be slow, and sometimes dont even work!
If anyone's interested, i'd be using PHP & FFMPEG along with a script similar to http://joesstuff.co.uk/youtube/
. I'd find the link to the MP4 File, WGET it (or use curl, either way), then convert it with ffmpeg.
