I do that with a webcam using ffmpeg. The format for video-only is this:
   ffmpeg -f video4linux -s vga -re /dev/video2 demo.mpg

To add audio, you need to use "-f audio_device -i {device}" and specify 
your device. I haven't wanted audio for what I'm doing, so I can't even 
guess what the audio device on your system is called.
