O.k. I have tried several options. My favorite one is to start lavrec 
every minute to record one frame, and afterwards start lavtrans to get a 
jpg.  The problem here is that lavrec doesn't exit after the task is 
done (even when I give the option  -t 1). This causes weird system behavior.

I tried it with: lavrec -f a -i p -d 2 -a 0 -S -t 1 test.avi

Is there a way to exit lavrec after a task is done? Or do I need to add 
a kill command to cron.

That was my first try. Xawtv uses v4l(2) for recording and I have some 
memory issues (limited memory). Because lavrec uses hardware encoding 
this is my preferred way.



Thanks for the response, I am almost there. Any suggestion is welcome!!!
