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=linux_input
disable-module=cle266
disable-module=cyber5k
disable-module=x11input
------------------------
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.
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
