No more need for third party browser plugins or websites that only convert one vid one at a time. It'll convert and save to CWD up to 300 of a user's videos to mp3s, one at a time. To increase, just increment the $count pattern. This is a concoction from commands #7718 and #7752, so it uses ffmpeg wget, curl, sed, and youtube-dl -- youtube-dl is only used to get the title of the video which it uses to name the mp3 file. You can use a different naming method if you want and the function should still work.

This is definitely a kludge!

What Others Think

Congratulations, you have just converted your music from one proprietary format into another, probably causing it to sound even worse due to transcoding issues. Also, it'll only work on DRM-free wma's which, I'm sad to say, are rare.

yes, I know, but my car audio can read only mp3. If you like ogg, just try: for f in *.wma; do ffmpeg -i "$f" -ab 128k "${f%.wma}.ogg" -ab 128K; done set -ab parameter how you like.

Nice, thanks! Just what I needed... Worked great on Mac OS X 10.8.2

I'm new to bash and trying to get this to work recursively (presumably using find). I had tried just executing something like: find ./ -name '*.wma' -type f -print0 | xargs -0 -I f ffmpeg -i "$f" -ab 128k "${f%.wma}.mp3" -ab 128K but the one part that's not working is the string mod op when saving the new mp3 file with an mp3 rather than wma extension. It seems like my piped variable is treated differently than when $f was just an expanded variable. What am I doing wrong here and is there an overall better approach? tia
