     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 - multiple displays

     9 - windows

    10 

    11 What you need:

    12 

    13 DirectFB 1.0.1, 1.2.x, 1.3.0

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

    15 Mesa 7.0.x	   - optional for OpenGL

    16 

    17 /etc/directfbrc

    18 

    19 This file should contain the following lines to make

    20 your joystick work and avoid crashes:

    21 ------------------------

    22 disable-module=joystick

    23 disable-module=linux_input

    24 disable-module=cle266

    25 disable-module=cyber5k

    26 disable-module=x11input

    27 ------------------------

    28 

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

    30 

    31 export SDL_DIRECTFB_YUV_DIRECT=1

    32 

    33 This is disabled by default. It will only support one 

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

    35 rendered in software.

    36 

    37 In addition, you may use (directfb-1.2.x)

    38 

    39 export SDL_DIRECTFB_YUV_UNDERLAY=1

    40 

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

    42 be shown.

    43 

    44 OPENGL Support
