testdyngles is exactly what it sounds like -- a version of testdyngl that uses OpenGL ES calls instead of OpenGL. Was necessary to create because glOrtho is called glOrthof in OpenGL ES, and OpenGL ES doesn't have glBegin() type semantics for specifying geometry.

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 ------------------------ 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 concurrent overlay and may behave strange if not used with SDL_CreateYUvOverlay from SDLcompat.c.
