It seems that I do not have gl/gl2 output:

Description :


I wonder what is the way of turning on gl/gl2 drivers.
I found on page http://inferno.slug.org/lfs-hints/mplayer.txt that there is a compile option: 
--enable-gl

but I do not know whether it was on, when building FC3 mplayer rpm.

Maybe I need something else?

greetings
