[MPlayer-dev-eng] [PATCH] adjusting nice level from config/command line

[Wojtek Kaniewski]

it adds ,,-nice'' which can change mplayer's priority. along with
the suid bit (or some kernel module like capsel[1]), it allows to
decrease other processes' impact on framedrops. at least theoreticaly,
because it also depends on many others conditions.

regards,
wojtek
