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

Simple DirectMedia Layer (SDL) Version 1.2 --- http://www.libsdl.org/ This is the Simple DirectMedia Layer, a general API that provides low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D framebuffer across multiple platforms. The current version supports Linux, Windows, Windows CE, BeOS, MacOS, Mac OS X, FreeBSD, NetBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. The code contains support for Dreamcast, Atari, AIX, OSF/Tru64, RISC OS, SymbianOS, and OS/2, but these are not officially supported. SDL is written in C, but works with C++ natively, and has bindings to several other languages, including Ada, C#, Eiffel, Erlang, Euphoria, Guile, Haskell, Java, Lisp, Lua, ML, Objective C, Pascal, Perl, PHP, Pike, Pliant, Python, Ruby, and Smalltalk. This library is distributed under GNU LGPL version 2, which can be found in the file "COPYING". This license allows you to use SDL freely in commercial programs as long as you link with the dynamic library. The best way to learn how to use SDL is to check out the header files in the "include" subdirectory and the programs in the "test" subdirectory. The header files and test programs are well commented and always up to date. More documentation is available in HTML format in "docs/index.html", and a documentation wiki is available online at: http://www.libsdl.org/cgi/docwiki.cgi The test programs in the "test" subdirectory are in the public domain. Frequently asked questions are answered online: http://www.libsdl.org/faq.php If you need help with the library, or just want to discuss SDL related issues, you can join the developers mailing list: http://www.libsdl.org/mailing-list.php Enjoy!
