ffmpeg supports quite a few audio sources. On Linux, alsa and
pulseaudio are the most likely candidates.

Check
https://www.ffmpeg.org/ffmpeg-devices.html

With pulseaudio, you can redirect what is going to your speakers (even
from just a single program) to a separate stream, which you would then
use as input to ffmpeg. You'll need to google for that separately
though. ;-)
