[MPlayer-users] Can I use mplayer/mencoder to capture the audio the Linux PC is playing to a file?

[James Board]

Hi.  Yahoo must have not sent my first email to this list.  So here it is.

I'm trying to figure out the easiest way to capture the audio that my Linux PC is
playing and save it to a file.  I don't want to capture from a URL.  I also don't want
to capture through the microphone, or analog capture device.  I simply want to
capture the bits that are being sent to the sound card.  My system uses pulseaudio.
I can currently capture the sound with a GUI program called audacity. I'd like
to do it with a command-line program instead.  Can I capture audio with either
mplayer or mencoder?  If not, what's the easiest way to do this?
