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

| 25 .PP | |
| 26 \fBSDL_ActiveEvent\fR is a member of the \fI\fBSDL_Event\fR\fR union and is used when an event of type \fBSDL_ACTIVEEVENT\fP is reported\&. | |
| 27 .PP | |
| 28 When the mouse leaves or enters the window area a \fBSDL_APPMOUSEFOCUS\fP type activation event occurs, if the mouse entered the window then \fBgain\fR will be 1, otherwise \fBgain\fR will be 0\&. A \fBSDL_APPINPUTFOCUS\fP type activation event occurs when the application loses or gains keyboard focus\&. This usually occurs when another application is made active\&. Finally, a \fBSDL_APPACTIVE\fP type event occurs when the application is either minimised/iconified (\fBgain\fR=0) or restored\&. | |
