mplayer -vo jpeg z-men.mpg
#(generates 1 JPEG per frame, plays all frames)

# mplayer -vo jpeg -ss 1:23:45 -frames 20 file.avi
#(-sseeks to 1 hour 23 minutes 45 seconds in file.avi, generates 20 JPEGs
#from the subsequent frames, quits)

#"man mplayer" for more stuff, like skipping to the start of a DVD
#chapter.
