[NCLUG] V4L Snapshot help

[Grant Johnson]

I have a working V4L device.   It displays nicely on xawtv and kdetv.

I would like to take snapshots from the composite input on it.   I would 
like to be able to do this from the command line without X being 
involved.   Basically, I would like to be able to set up a cron job to 
take snapshots from a low-light CCTV camera.  

Any suggestions on what applications may work for me?
