I am ripping some CDs and converting the .wav files to .mp3. I can do
this with the following in Ubuntu 18.04:

for file in *.wav; do ffmpeg -i "${file}"  -acodec libmp3lame -ab
220k "${file/.wav/.mp3}"; done

When I run that in Slackware 14.2 I get the error message:

Unknown encoder 'libmp3lame'

I have installed slackpkgs for ffmpeg and lame. I'm guessing that the
codec provided by the slackpkg has a different name. How do I figure
that out? Or is there something else I'm missing here?

$ ffmpeg -encoders
  and see if you can find one relating to mp3 in there. However If it's
  not in there that's probably due to how licensing that codec was back
  in the 90s.

I don't find mp3 there. However, I have found a suitable alternative. I searched the mighty Interwebs and discovered folks use k3b, which is installed by default in Slackware. It allows me to insert a CD and rip it to mp3s or, as an option, create a single mp3 file, which is my eventual goal. It will also let me specify .wav files already on my hard drive.

Thanks, though, for the pointer.
