Danke, Kiste.

with -vf framestep=2500 it works and saves one frame every 100 seconds. 
However, something strange happens with another -vf option.

mplayer -vf mirror -vf framestep=50 tv:// -tv 
driver=v4l2:device=/dev/easycap0  -nosound -vo jpeg then only the mirror is 
accepted and the framestep is ignored.
I'm trying to find out on the WWW how to combine two -vf options in one 
line. (My camera is a wheatherproof car camera for which the image has to be 
mirrorred).

Thanks again !
