Raw Normal View History

All:
Audio rate conversion is only implemented by multiplying or dividing
by a power of two. This is a side-effect of the requirement that the
raw audio buffer size be a power of two, and can hopefully be fixed.
This means 8 KHz audio converted to 22 KHz ends up being 16 KHz. :-/
When the implementation is writing directly to video memory the mouse
cursor doesn't work properly. Applications which do this should use
their own mouse cursor and call SDL_ShowCursor(0) to hide the system
cursor.
Linux:
Wide UNICODE character input (Kanji, etc.) is not yet supported.
It requires handling of keyboard mapping events and using the XIM
input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.
The keyboard modifiers are not set to the correct state on startup.
The AAlib, GGI, and SVGAlib video drivers are not heavily tested.
Win32:
The MCI driver can't tell if the CD-ROM drive is paused or stopped.
The SDL_INIT_EVENTTHREAD flag is not supported on Win32
(Idea: create a separate DirectInput polling thread)
The main purpose of this flag is for smooth cursor motion in
fullscreen environments.
Wide UNICODE character input (Kanji, etc.) is not yet supported.
This requires the ToUnicode() API which is only implemented on
Windows NT/2000, not on Windows 95/98.
Latin-1 keyboard input works fine.
Joysticks are only supported under the Win32 MultiMedia API,
DirectInput support is not yet implemented.
BeOS:
BePPC is not supported, apparently not even by Be Inc.
SDL_WM_GrabInput() is not implemented.
Does anyone know how to do this? SDL_WM_GrabInput() is designed
to prevent the user from switching input and mouse focus away from
the SDL application.
Continuous relative mouse motion is not implemented.
Wide UNICODE character input (Kanji, etc.) has not been tested.
Latin-1 keyboard input works fine.
MacOS:
Palette handling isn't implemented in windowed mode yet.
Audio hasn't been extensively tested, in particular the locking
isn't implemented and mixer routines may not call malloc() or free()
because they are called at interrupt time.
SDL_WM_GrabInput() is not implemented.
Does anyone know how to do this? SDL_WM_GrabInput() is designed
to prevent the user from switching input and mouse focus away from
the SDL application.
Continuous relative mouse motion is not implemented.
SDL_AddTimer() and SDL_RemoveTimer() haven't been implemented yet.
Not all of the keys are properly recognized on the keyboard.
MacOS X:
Depth switching for windowed mode isn't implemented yet.
Palette handling isn't implemented in windowed mode yet.
Command-line arguments dialog is not implemented yet.
Fullscreen drawing has some artifacts.
Fullscreen OpenGL for the software renderer is broken.
Some OpenGL parameters are not accounted for, for example color bits customization.
Continuous mouse motion perhaps is not as smooth as it should be.
SDL_WM_GrabInput() is implemented, but it "freezes" the hardware
cursor in the center of the window/screen. Also, mouse moved events
are not generated, and the keyboard cannot be grabbed.
MacOS X seems to have a broken pthread_cancel() implementation.
Actually, it just only has one cancellation point defined.

FreeBSD:
pthread_cancel() isn't supported by FreeBSD 3.X, so threads don't
work on versions of FreeBSD earlier than 4.0.
The CD-ROM handling doesn't work completely.
Wide UNICODE character input (Kanji, etc.) is not yet supported.
It requires handling of keyboard mapping events and using the XIM
input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.
The keyboard modifiers are not set to the correct state on startup.
Solaris:
The joystick functions are not implemented yet.
Wide UNICODE character input (Kanji, etc.) is not yet supported.
It requires handling of keyboard mapping events and using the XIM
input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.

IRIX:

input translation extension. I will implement it as requested.
Latin-1 keyboard input works fine.
The keyboard modifiers are not set to the correct state on startup.
EPOC:
Only Crystal version of Epoc/SymbianOS is currently supported.
SDL is implemented in static library only. SDL uses static/global
variables and that is not allowed in EPOC dll libraries.
Sound is not yet supported.
Joystick, OpenGL and cdrom is not supported (think about cdrom in a cell phone:-).
No console output screen. Printing to stdout do not have any effect.
Date: Sat, 2 Aug 2003 16:22:51 +0300 From: "Mike Gorchak" Subject: New patches for QNX6 Here my patches for the SDL/QNX: QNXSDL.diff - diff to non-QNX related sources: - updated BUGS file, I think QNX6 is now will be officially supported - configure.in - added shared library support for QNX, and removed dependency between the ALSA and QNX6. - SDL_audio.c - added QNX NTO sound bootstrap insted of ALSA's. - SDL_sysaudio.h - the same. - SDL_nto_audio.c - the same. - SDL_video.c - right now, QNX doesn't offer any method to obtain pointers to the OpenGL functions by function name, so they must be hardcoded in library, otherwise OpenGL will not be supported. - testsprite.c - fixed: do not draw vertical red line if we are in non-double-buffered mode. sdlqnxph.tar.gz - archive of the ./src/video/photon/* . Too many changes in code to make diffs :) : + Added stub for support hide/unhide window event + Added full YUV overlays support. + Added window maximize support. + Added mouse wheel events. + Added support for some specific key codes in Unicode mode (like ESC). + Added more checks to the all memory allocation code. + Added SDL_DOUBLEBUF support in all fullscreen modes. + Added fallback to window mode, if desired fullscreen mode is not supported. + Added stub support for the GL_LoadLibrary and GL_GetProcAddress functions. + Added resizable window support without caption. ! Fixed bug in the Ph_EV_EXPOSE event handler, when rectangles to update is 0 and when width or height of the rectangle is 0. ! Fixed bug in the event handler code. Events has not been passed to the window widget handler. ! Fixed codes for Win keys (Super/Hyper/Menu). ! Fixed memory leak, when deallocation palette. ! Fixed palette emulation code bugs. ! Fixed fullscreen and hwsurface handling. ! Fixed CLOSE button bug. First event was passed to the handler, but second terminated the application. Now all events passed to the application correctly. - Removed all printfs in code, now SDL_SetError used instead of them. - Disabled ToggleFullScreen function. README.QNX - updated README.QNX file. Added much more issues. --HG-- extra : convert_revision : svn%3Ac70aab31-4412-0410-b14c-859654838e24/trunk%40664
