Subject: Directfb driver for SDL1.3
Hi,
the attachment contains a patch for a SDL1.3 directfb driver. It supports:
- Renderer "directfb":
Hardware acceleration as supported by the underlying directfb driver. With a
radeon X850, testsprite2 runs at 50% to 70% of OpenGL (X11, dri) performance.
Also supports hardware accelerated yuv overlays. This must be enabled by sett
ing:
export SDL_DIRECTFB_YUV_DIRECT=1
- Renderer "opengl"
Supports software opengl using mesa opengl (make linux-directfb).
Some more information may be found in README.DirectFB
There will certainly still be some bugs, and there is some debug code around.
When I find some time, I will compile against directfb-0.9.25 as distributed
with ubuntu 7.04.
The diff also contains a fix for SDL_LockYUVOverlay fixing a bug in *pixels
and pitches initialization.
Kind regards,
couriersud

The latest development version of SDL is available via Subversion. Subversion allows you to get up-to-the-minute fixes and enhancements; as a developer works on a source tree, you can use svn to mirror that source tree instead of waiting for an official release. Please look at the Subversion website ( http://subversion.tigris.org/ ) for more information on using svn, where you can also download software for MacOS, Windows, and Unix systems. svn checkout http://svn.libsdl.org/trunk/SDL If you are building SDL with an IDE, you will need to copy the file include/SDL_config.h.default to include/SDL_config.h before building. If you are building SDL via configure, you will need to run autogen.sh before running configure. There is a web interface to the subversion repository at: http://www.libsdl.org/cgi/viewvc.cgi
