1 SDL on DirectFB

     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.
