forget adding more command line options to specify grab devices and formats
also look at ffmpeg.c first (grep for grab) theres already lots of redundant
grabbing options there which rather should be removed instead of adding yet
more

logically correct is:

ffmpeg -f x11 -i some_nice_syntax_to_specify_the_display_and_location
ffmpeg -f v4l -i /dev/video1

When the tyrant has disposed of foreign enemies by conquest or treaty, and
there is nothing more to fear from them, then he is always stirring up
some war or other, in order that the people may require a leader. -- Plato
