need help on osd_show_text

[ml at bortal.de (ml at bortal.de)]

Hello List,

i am using this proof-of-concept script for osd_show_text:
----------------------------------------------------------------------------------------------------
mkfifo /tmp/fifo
mplayer -loop 10 -fs -slave -input file=/tmp/fifo contagion.AVI &
while true; do
        echo "osd_show_text HalloWorld 10000 0" > /tmp/fifo
        sleep 3
done


I would like to know how i can:
----------------------------------------------------
1.) Change the position of the osd_show_text (y-position and x-position)
2.) How can i print more than one line? (echo -e "foo \n bar" did not 
work for me)
3.) Can i change the color and font of the text?

Thanks,
Mario
