Of course, but OSX is a sort-of unix, so some sort of indication could
probably be provided if someone feels absolutely certain that there
actually are audio-in devices that can be specified as input for ffmpeg.
I have a nasty feeling there might be more to it than just specifying a
device name, one should probably add something to tell if it's alsa or
jack (under linuxy environs) or what. Or whatever the audio in channel
protocols are in Mac OSX.
