| SDL on DirectFB |
| |
| Supports: |
| |
| - Hardware YUV overlays |
| - OpenGL - software only |
| - 2D/3D accelerations (depends on directfb driver) |
| - multiple displays |
| - windows |
| |
| What you need: |
| |
| DirectFB 1.0.1, 1.2.x, 1.3.0 |
| Kernel-Framebuffer support: required: vesafb, radeonfb .... |
| Mesa 7.0.x - optional for OpenGL |
| |
| /etc/directfbrc |
| |
| This file should contain the following lines to make |
| your joystick work and avoid crashes: |
| ------------------------ |
| disable-module=joystick |
| disable-module=cle266 |
| disable-module=cyber5k |
| no-linux-input-grab |
| ------------------------ |
| |
| To disable to use x11 backend when DISPLAY variable is found use |
| |
| export SDL_DIRECTFB_X11_CHECK=0 |
| |
| To disable the use of linux input devices, i.e. multimice/multikeyboard support, |
| use |
| |
| export SDL_DIRECTFB_LINUX_INPUT=0 |
| |
| 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 (directfb-1.2.x) |
| |
| export SDL_DIRECTFB_YUV_UNDERLAY=1 |
| |
| to make the YUV texture an underlay. This will make the cursor to |
| be shown. |
| |
| Simple Window Manager |
| ===================== |
| |
| The driver has support for a very, very basic window manager you may |
| want to use when runnning with "wm=default". Use |
| |
| export SDL_DIRECTFB_WM=1 |
| |
| to enable basic window borders. In order to have the window title rendered, |
| you need to have the following font installed: |
| |
| /usr/share/fonts/truetype/freefont/FreeSans.ttf |
| |
| OPENGL Support |
| ============== |
| |
| As of this writing 20070810 you need to pull Mesa from git and do the following: |
| |
| ------------------------ |
| cd mesa |
| make linux-directfb |
| make |
| |
| echo Installing - please 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 |
