SDL Description

Simple DirectMedia Layer is a cross-platform multimedia library. Simple DirectMedia Layer is a cross-platform multimedia library designed to provide low level access to audio, keyboard, mouse, joystick, 3D hardware via OpenGL, and 2D video framebuffer. SDL is used by MPEG playback software, emulators, and many popular games, including the award winning Linux port of "Civilization: Call To Power."Simple DirectMedia Layer supports Linux, Windows, BeOS, MacOS Classic, MacOS X, FreeBSD, OpenBSD, BSD/OS, Solaris, IRIX, and QNX. There is also code, but no official support, for Windows CE, AmigaOS, Dreamcast, Atari, NetBSD, AIX, OSF/Tru64, RISC OS, and SymbianOS.SDL is written in C, but works with C++ natively, and has bindings to several other languages, including Ada, Eiffel, Java, Lua, ML, Perl, PHP, Pike, Python, and Ruby. What's New in This Release: General Notes: · Fixed flicker when resizing the SDL window · Fixed crash in SDL_SetGammaRamp() · Fixed freeze in SDL_memset() with 0 length when assembly code is disabled. · Added SDL_DISABLE_LOCK_KEYS environment variable to enable normal up/down events for Caps-Lock and Num-Lock keys. · Fixed audio quality problem when converting between 22050 Hz and 44100 Hz. · Fixed a threading crash when a few threads are rapidly created and complete. · Increased accuracy of alpha blending routines. · Fixed crash loading BMP files saved with the scanlines inverted. · Fixed mouse coordinate clamping if SDL_SetVideoMode() isn't called in response to SDL_VIDEORESIZE event. · Added doxygen documentation for the SDL API headers. Unix Notes: · Fixed potential memory corruption due to assembly bug with SDL_revcpy() · Fixed crashes trying to detect SSE features on x86_64 architecture. · Fixed assembly for GCC optimized 50% alpha blending blits. · Added configure option --enable-screensaver, to allow enabling the screensaver by default. · Use XResetScreenSaver() instead of disabling screensaver entirely. · Removed the maximum window size limitation on X11. · Fixed SDL_GL_SWAP_CONTROL on X11. · Fixed setting the X11 window input hint. · Fixed distorted X11 window icon for some visuals. · Fixed detecting X11 libraries for dynamic loading on 64-bit Linux. · SDL_GL_GetAttribute(SDL_GL_SWAP_CONTROL) returns the correct value with GLX_SGI_swap_control. · Added SDL_VIDEO_FULLSCREEN_DISPLAY as a preferred synonym for SDL_VIDEO_FULLSCREEN_HEAD on X11. · The SDL_VIDEO_FULLSCREEN_DISPLAY environment variable can be set to 0 to place fullscreen SDL windows on the first Xinerama screen. · Added the SDL_VIDEO_FBCON_ROTATION environment variable to control output orientation on the framebuffer console. Valid values are: not set - Not rotating, no shadow; "NONE" - Not rotating, but still using shadow; "CW" - Rotating screen clockwise; "UD" - Rotating screen upside down; "CCW" - Rotating screen counter clockwise. · Fixed DirectFB detection on some Linux distributions. · Added code to use the PS3 SPE processors for YUV conversion on Linux. · Updated ALSA support to the latest stable API · ALSA is now preferred over OSS audio. (SDL_AUDIODRIVER=dsp will restore the previous behavior.) · Improved support for PulseAudio · The Network Audio System support is now dynamically loaded at runtime. · Fixed crash with the MP-8866 Dual USB Joypad on newer Linux kernels. · Fixed crash in SDL_Quit() when a joystick has been unplugged.
