/*
MPlayer video driver for DirectFramebuffer device
(C) 2001
Written by Jiri Svoboda <Jiri.Svoboda@seznam.cz>
Inspired by vo_sdl and vo_fbdev.
To get second head working delete line 120
from fbdev.c (from DirectFB sources version 0.9.7)
Line contains following:
fbdev->fd = open( "/dev/fb0", O_RDWR );
