[MPlayer-users] Mplayer and the fps setting

Setting the FPS is probably not at all what you want. If you change the 
fps value, all frames will be displayed, but at a speed differing from 
the original. I think you want to save one frame, skip a lot of frames, 
and then save another one. To save one frame every 100 seconds @ 25fps, 
I would use

mplayer videofile.avi -af framestep=2500 -vo jpeg
