Me found for you http://www.smcc.demon.nl/camstream/
Is there any software out there that will let me view video signal from a USB webcam and record it on Linux?
you can also try to run a programm called motion. its a command line tool and it can be run as a daemon which records and reencodes your video from your video cam. so what you do is, you capture the video from your webcam with motion and save it to your harddrive. motion will then also reencode the video and serve it on a tcp/ip socket so you can play it with any mediaplayer that supports the correct streaming video format. for example vlc or mplayer should work pretty well.
motion works with any video for linux video device and it can even capture video from ip webcams.
maybe that is of help for you.
