    31
slouken@2226
    32
export SDL_VIDEODRIVER=directfb
slouken@2226
    33
export LD_LIBRARY_PATH=/usr/local/dfb_GL/lib
slouken@2226
    34
export LD_PRELOAD=/usr/local/dfb_GL/libGL.so.7
slouken@2226
    35
slouken@2226
    36
./testgl
slouken@2226
    37

To use hardware accelerated YUV-overlays for YUV-textures, use:
slouken@2226
    39
slouken@2226
    40
export SDL_DIRECTFB_YUV_DIRECT=1
slouken@2226
    41

    42
This is disabled by default. It will only support one concurrent

slouken@2226
    44
from SDLcompat.c.
