Of course if you just want to play 4 videos all at once you can use 4
instances of mplayer with -geometry set to occupy the appropriate portion
of the screen. Sorry about the layout of this which i cut and paste from
the man page.
-geometry x[%][:y[%]] or [WxH][+x+y]
Adjust where the output is on the screen initially. The x
and y specifications are in pixels measured from
the top-left of the screen to the top-left of the image
being displayed, however if a percentage sign is
given after the argument it turns the value into a
percentage of the screen size in that direction. It al-
so supports the standard X11 -geometry option format. If
an external window is specified using the -wid
option, then the x and y coordinates are relative to the
top-left corner of the window rather than the
screen.
NOTE: This option is only supported by the x11, xmga, xv,
xvmc, xvidix, gl, gl2, directx and tdfxfb video
output drivers.
EXAMPLE:
50:40
Places the window at x=50, y=40.
50%:50%
Places the window in the middle of the screen.
100%
Places the window at the middle of the right edge of
the screen.
100%:100%
Places the window at the bottom right corner of the
screen.
