See http://www.pulseaudio.org/wiki/Modules and read about module-null-sink and module-loopback. You can obviously only record from one source (for screencasting - probably a monitor), but you can also loop back any number of sources to the sink whose monitor you're recording. That can be a null sink, too, so that you don't get feedback through your speakers. Obviously that's not relevant to VLC itself, it's through pactl/pacmd (sorry) and pavucontrol that you need to select the appropriate recording source.
