SDL on DirectFB

 Supports:

 - Hardware YUV overlays

 - OpenGL - software only

 - 2D/3D accelerations (depends on directfb driver)

 What you need:

 DirectFB 1.0.0 - required

 Kernel-Framebuffer support: required: vesafb, radeonfb .... 

 Mesa 7.0.x	   - optional for OpenGL

 As of this writing 20070810 you need to pull Mesa from git and do the following:

 ------------------------

 cd mesa 

 make linux-directfb

 make

 echo Installing - pleaser enter sudo pw.

 sudo make install INSTALL_DIR=/usr/local/dfb_GL

 cd src/mesa/drivers/directfb

 make

 sudo make install INSTALL_DIR=/usr/local/dfb_GL

 ------------------------

 /etc/directfbrc

 This file should contain the following two lines to make

 your joystick work:

 ------------------------

 disable-module=joystick

 disable-module=linux_input

 ------------------------

 To run the SDL - testprograms:

 export SDL_VIDEODRIVER=directfb

 export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib

 export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7

 ./testgl

 To use hardware accelerated YUV-overlays for YUV-textures, use:

 export SDL_DIRECTFB_YUV_DIRECT=1

 This is disabled by default. It will only support one 

 YUV texture, namely the first. Every other YUV texture will be

 rendered in software.

 In addition, you may use 

 export SDL_DIRECTFB_YUV_UNDERLAY=1

 to make the YUV texture an underlay. This will make the cursor to

 be shown.
