Recent changes in SDL_sysrenderer.h and SDL_sysvideo.h had no impact on directfb backend.
Attached patch:
- updates interface,
- resolves uninitialized variable reading,
- changes logging tio use SDL_Log API,
- updates configure to use DIRECTFBCONFIG variable instead direct call to directfb-config.
attached is a working directfb driver diff which works with the current
changes. There are a number of changes around it as well, e.g.
configure.in.
The directfb renderdriver right now still depends on a some "includes"
from src/video/directfb. That's why it is not yet moved to the new
render folder.
Hi Sam,
20100815_1.diff contains updates for the directfb driver:
- more documentation, mainly on software OpenGL in README.directfb
- Revised error handling leading to leaner code
- Improved/fixed OpenGL handling of multiple contexts.
- Made the built-in simple window manager handle OpenGL windows.
- Rewrote pixelformat mapping - this was quite ugly before.
Well, all software GL, but working :-)
I have done some quick changes and at least the code compiles again. It
also works with a number of the test executables with the DFB X11
backend. I hope to find time to get SDLMAME to work with latest SDL1.3
(i.e. rip out multi-keyboard, multi-mice & cursor support) next week to
test it further.
Regards,
André

- use SDL_getenv, not getenv ...
- no more support for 0.9.25 - not even mentioned any longer on directfb.org
- fix fullscreen issues
- add a simple window manager unless the directfb team comes up with a working wm.
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 including icon support. In order to have the window title rendered,
you need to have the following font installed:
/usr/share/fonts/truetype/freefont/FreeSans.ttf

Subject: SDL1.3 DirectFB patches
The attached contains the following directfb changes:
- Dynamic loading of libdirectfb.so. This may to turned off as well in configure
- Use linux-input by default. May be switched off by environment variable.
- Added some code which will use directfb's x11 backend when DISPLAY is set.

Subject: SDL: Mouse last_x, last_y into SDL_Mouse
the attached diff moves the static vars last_x and last_y into
SDL_Mouse. These, as far as I understand it, should be tied to the
individual mouse.
The patch also makes the code check for out of window conditions of
mouse->x,y when relative movements are passed to MouseSendMotion.
Also attached is the latest DirectFB code (dfb20081208) supporting
multiple mice and keyboards. This works quite well with sdlmame now. It
however needs more testing with different directfb configurations.

Subject: Re: Updated DirectFB driver for SDL1.3
attached is a patch which brings the directfb driver in line with
current svn. In addition:
* driver now is in line with the structure of the X11 driver.
This adds a couple of files.
* driver now supports relative mouse movements

Subject: Updated DirectFB driver for SDL1.3
please find attached a patch for an updated directfb driver for SDL1.3.
It does now
- properly supported the new input api.
- send unicode text events
- support directfb windows
- support multiple screens
- support hardware YUV scaling for the first YUV texture created.
- support hardware scaling for textures.
- properly interpret streaming access
- support software opengl if one manages to install the mesa directfb
driver (broken/not broken in mesa svn)
Within bugzilla (http://bugzilla.libsdl.org/show_bug.cgi?id=603) there
is another patch which fixes a crash due to GL context creation.
Kind regards,
couriersud

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

Make sure every source file includes SDL_config.h, so the proper system
headers are chosen.
