     2 
       
     3 Supports:
       
     4 
       
     5 - Hardware YUV overlays
       
     6 - OpenGL - software only
       
     7 - 2D/3D accelerations (depends on directfb driver)
       
     8 
       
     9 What you need:
       
    10 
       
    11 DirectFB 1.0.0 - required
       
    12 Kernel-Framebuffer support: required: vesafb, radeonfb .... 
       
    13 Mesa 7.0.x	   - optional for OpenGL
       
    14 
       
    15 As of this writing 20070810 you need to pull Mesa from git and do the following:
       
    16 
       
    17 ------------------------
       
    18 cd mesa 
       
    19 make linux-directfb
       
    20 make
       
    21 
       
    22 echo Installing - pleaser enter sudo pw.
       
    23 
       
    24 sudo make install INSTALL_DIR=/usr/local/dfb_GL
       
    25 cd src/mesa/drivers/directfb
       
    26 make
       
    27 sudo make install INSTALL_DIR=/usr/local/dfb_GL
       
    28 ------------------------
       
    29 
       
    30 To run the SDL - testprograms:
       
    31 
       
    32 export SDL_VIDEODRIVER=directfb
       
    33 export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib
       
    34 export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7
       
    35 
       
    36 ./testgl
       
    37 
       
    38 To use hardware accelerated YUV-overlays for YUV-textures, use:
       
    39 
       
    40 export SDL_DIRECTFB_YUV_DIRECT=1
       
    41 
       
    42 This is disabled by default. It will only support one concurrent 
       
    43 overlay and may behave strange if not used with SDL_CreateYUvOverlay
       
    44 from SDLcompat.c.
