"The MPlayer offers dozen of video output options you can use to
change the way the video file is showed such as '-brightness',
'-contrast', '-fs' fullscreen playback, '-geometry', '-saturation'
and more. For example, you can play a video file by setting its
color to grayscale and fullscreen by using 'mplayer -fs -saturation
-100 file.mpeg'. Some of these video output options can be also
used to video output drivers, you need to read the man page to see
what you can use."
