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.
