/*
 * CHANGELOG.
 */

05222002 - Torbjörn sent in some more fixes for altcvt: stereo to mono
           conversion works, now.
05222002 - Torbjörn sent in some initial cleanups and fixes for altcvt, and
           fixed a bug in playsound when not all three of --rate, --channels
           and --format are specified.
05202002 - Some .cvsignores from Max and me. Added a seek implementations for
           the SMPEG, ogg, aiff, wav-adpcm, voc, and au decoders. Added a seek
           stub to quicktime.c. playsound now takes milliseconds in the seek
           lists: --seek "00:00:400" or whatnot. Corrected playsound's usage
           text. Other au.c cleanups for extra robustness. Added an
           experimental audio converter that Frank Ranostaj sent to the SDL
           mailing list about a month ago: enable it with --enable-altcvt at
           configure time, but be warned that it doesn't work very well right
           now.
04292002 - Darrell Walisser updated the Mac Classic and OS X project
           files, fixed some portability issues, and added an
           experimental decoder that uses Apple's QuickTime libraries 
           (see decoders/quicktime.c). I've included the Mac project files 
           in CVS, now. Removed all use of alloca() from playsound.
04242002 - Added --seek option and bugfixes to playsound.c. Torbjörn comes
           through with seek support for the FLAC, MIDI, and ModPlug
           decoders (and some stub code for MikMod), and a bugfix for sample
           flag manipulation in the base library (and his own --seek code for
           playsound, which unfortunately we're not using).
04232002 - Cleaned up the playsound command line handling. Most command line
           options (--rate, --format, --predecode, etc) are specified per-file
           and reset to their defaults after each sample is played back.
           --loop now takes a numeric argument: --loop 2 will playback the
           sample three times (one playback and two loops). Added Darrell
           to the playsound credits.
04212002 - Initial work to add a Sound_Seek() API. Removed the NEEDSEEK
           sample flag (replaced it with CANSEEK). Hack to change the internal
           Sound_SetError() function to __Sound_SetError(). Added internal
           function __Sound_convertMsToBytePos().
04082002 - Cleaned up the archive support in playsound a little bit, and 
           fixed a PhysicsFS bug in the process.
03252002 - Win32 patches and fixes from Tyler Montbriand: handled "inline"
           keyword, fixed SNDDBG macros in mpglib, and renamed a conflicting
           file (decoders/mpglib/common.c to decoders/mpglib/mpglib_common.c).
03172002 - Removed an unneeded #include in mpglib that broke build on BeOS.
           mpglib seems to work find on BeOS. Reworked some of mpglib.c so we
           can determine the audio format when accepting the data stream. Some
           other minor cleanups here and there.
03162002 - Tied the PhysicsFS code into the build system (code disabled if
           physfs not found or --disable-physfs passed to ./configure.)
03152002 - Added PhysicsFS support to playsound, so you can play sound files
           that are in ZIP files without unzipping them. Needs to be merged
           into build system (I was just testing my PhysFS->RWops glue code).
03142002 - Changed configure script's --enable-vorbis to --enable-ogg. Removed
           global state variable from mpglib, so it should be reentrant now
           (patches sent to mpglib's actual maintainer). playsound can now
           read from stdin.
03102002 - Added a FIXME note to decoders/mpglib.c. playsound now reports
           errors in the thread where they occured, which also fixes a double
           report of errors during predecoding. Removed all calls to exit() in
           mpglib. These calls now report errors correctly to SDL_sound, which
           passes them on to the application (patch also sent to mpglib's
           actual maintainer). Replaced all stderr chatter in mpglib with
           Sound_SetError() calls.
03072002 - decoders/mpglib.c now disregards ID3 tags instead of passing them
           on as valid MP3 data to mpglib. Added some (buggy) example code for
           adjusting an audio stream's volume (via the new --volume command
           line in playsound).
03032002 - Fixed mpglib's build configuration to include general build flags
           so that things like --enable-debug work as expected.
02212002 - Changed SMPEG's URL to point to the icculus.org site. Added an
           mpglib decoder (internal to SDL_sound; relies on no external libs)
           and changes mp3.c to smpeg.c (and other associated things).
02112002 - Committed a patch from Torbjörn to fix incorrect memory accesses
           in the Timidity code. Changed the magic number in the AU decoder
           to be bigendian (seems appropriate). Updated README for
           completeness, and TODO for accuracy. Darrell sent in updated
           MacOS X Project Builder files (on the website).
02072002 - Committed a patch Torbjörn sent in awhile ago for preventing
           confusion with Timidity++-specific stuff in the timidity.cfg file.
           Tyler Montbriand sent in an updated Visual C package.
           Updated SDL_sound.h's comments a little. Upped version to 0.1.5.
02052002 - Fixed a cleanup I broke last night. Added CWProject.sit to the
           EXTRA_DIST section of Makefile.am, and updated the README with
           MacOS (9/X) install instructions.
02042002 - Darrell Walisser submitted some cleanups and CodeWarrior project
           files for MacOS 9. Sweet!
01232002 - Max fixed decoders/Makefile.am to work with seperate build
           directories, and corrected some dates in this file.
01192002 - Torbjörn sent in patches implementing the rewind method for the
           rest of the decoders except shn.c, for which I added a kludged
           implementation. Added more info to the README. Hunted down the
           reason why SMPEG can't decode before calling SDL_OpenAudio(), and
           it can't be fixed without a change to SMPEG (not MY fault! :) ).
           Made ModPlug take priority over MikMod when selecting a decoder.
           Mutex-protected the internal samples list, and fixed some bugs in
           the management of that list. Changed some stuff to use uniform
           coding conventions.
01182002 - SDL_sound/playsound builds and runs on BeOS now. Fixed an assertion
           bug I introduced yesterday.
01172002 - Implemented Sound_Rewind(), and added a --loop command line to
           playsound for testing. Rewrote the audio callback to handle looping
           with both predecoded and streamed samples. Most of the decoders
           just have an assert(0) in their internal rewinding method at this
           point. I implemented the WAV, VOC, AU, AIFF, and RAW ones, for now.
           (...and skeleton.c, for what that's worth.) A few tweaks in the
           core API implementation to fix unlikely but possible leaks.
01112002 - Mattias Engdegård sent in an .AU decoder. Nice! He also tweaked
           playsound to try and wait until SDL has completed playing a given
           sound before closing the audio device. Changed a macro in
           decoders/shn.c to be more uniform with the other decoders.
           SDL_sound error messages are now maintained on a per-thread basis,
           and do not interfere with SDL_[GS]etError() anymore.
01112002 - Committed the rest of Torbjörn's MOD patches, to clean up file
           extension handling.
01092002 - Torbjörn comes through with a ModPlug-based decoder, which should
           work nicely for decoding multiple .MODs at once. Now we need to
           figure out what to do with two decoders that can decode the same
           file. For now, if you explicitly want either MikMod or ModPlug, you
           should explicitly enable one decoder and disable the other on the
           configure command line ("--enable-modplug --disable-mikmod", for
           example), otherwise configure will try to sort out the best one for
           your system. Choice is a wonderful thing.  :)
01042002 - Forgot to bump playsound's version to match SDL_sound's. Fixed.
           Added some notes to the top of COPYING about other libraries, etc.
           A real MIDI decoder (using a hacked version of the hacked version
           of Timidity from SDL_mixer) is now in place and working well,
           thanks to Torbjörn.
01012002 - Happy New Year. Added some debug output to wav.c for future
           codecs (GSM comes to mind). Fixed the SMPEG decoder's URL to point
           to Loki's webpage.
12302001 - Upped version to 0.1.4.
12272001 - Added --audiobuf and --decodebuf options to playsound to make
           tracking down a bug in the ADPCM decoder easier (plus, it could
           help for benchmarking, etc later on...). Found a printf() bug in
           playsound (extra comma in there...). ADPCM decoder appears to be
           functional now. Tried to add ElectricFence support to
           configure.in, and failed. All this libtool/autoconf stuff makes my
           head hurt.
12262001 - Changed remaining references to the "LICENSE" file into "COPYING".
           Work progresses on the ADPCM-compressed .wav decoder. Updates to
           the documentation in SDL_sound.h. Hhmm...find_chunk() in wav.c was
           badly broken. Fixed.
12162001 - FLAC decoder now checks for the magic number unless the file
           extension is recognized. This was changed back because searching
           for metadata, while probably more effective, is VERY expensive (and
           useless) on non-FLAC streams.
12052001 - Put our names in a "--credits" option in playsound, and put the
           standard GNU disclaimers in there too, for good measure. Renamed
           LICENSE to COPYING to match GNU standards more closely (and to
           end Max's torment.  :)  ) Tweaks to wav.c, and work on aiff.c to
           make it easier to support multiple audio formats (for compression
           handling later down the road).
11302001 - Torbjörn and I make Sound_DecodeAll() more robust: checks for
           previous decoding failures and sets an appropriate error, handles
           decoders that change their buffers on the fly (such as the FLAC
           decoder), and deals with out-of-memory conditions more gracefully.
11252001 - (With thanks to Andreas Umbach for pointing it out) Fixed some
           problems with Sound_DecodeAll(). For local testing of this bug,
           added a --predecode command line to playsound. Minor fixes to
           theoretical bugs in Sound_FreeSample(). playsound no longer
           buffers stdout and stderr. Updated Sound_DecodeAll()'s comments in
           SDL_sound.h ...
11192001 - FLAC decoder cleanups from Torbjörn.
11092001 - Torbjörn fixes playsound's audio callback after I broke it, again.
           A bug in configure.in was preventing SMPEG from being used unless
           --enable-debug was set; fixed. Changed this file to list latest
           changes first. Torbjörn submitted a FLAC decoder that utilizes
           libFLAC (http://flac.sf.net/). Cool.
11012001 - API COMPATIBILITY BREAKAGE: Decoders can now list multiple file
           extensions each. Playsound has been updated to handle this.
           Playsound now registers a SIGINT handler, so you can skip tracks
           and/or abort the way that mpg123 does.
10232001 - Rewrote playsound.c's audio_callback() to no longer need the
           overflow buffer hack, which streamlines it a little and trims the
           memory requirements for playsound by about 16 kilobytes.
10172001 - Torbjörn catches a problem with the overflow buffer in playsound's
           audio callback.
10152001 - Torbjörn sends in a default sample format for the MIDI decoder, 
           and the starts of the audio conversion funcitonality (ripped 
           from SDL). Officially released 0.1.3. Added LICENSE and 
           CHANGELOG to the distribution. (Again, from Torbjörn) added in 
           the start of a tweaked audio converter.
10122001 - Torbjörn Andersson submitted command line enhancements to 
           playsound, and I cleaned up the --help output.
10092001 - Patches to shn.c for Visual C compatibility. Visual C project files
           available from the website. Changed Corona688 to Tyler Montbriand
           in CREDITS. Upped version to 0.1.3.
10082001 - Restructured decoders/wav.c to allow for multiple formats, and 
           put the start of a handler for the ADPCM format in place.
10072001 - Changed the way decoders/mod.c handles samplerate so that it should
           work universally. This isn't an ideal solution, but it's probably
           the best we can do without rewriting mikmod. Made a change to ogg.c
           for portability: changed an int64_t to ogg_int64_t.
10062001 - Made a change to SDL_sound.c for compiling on non-GNU toolchains.
10052001 - Removed #include "SDL_endian" from aiff.c.
10042001 - Changed some #if (defined SOUND_SUPPORTS_*) lines to
           #ifdef SOUND_SUPPORTS_* in voc.c and shn.c, for consistency with
           the other decoders.
10032001 - After hours of tracking down a bogus pointer, the SHN decoder works!
           I can die happy. :)  Max placated me with an --enable-debug option
           so I could stop my whining. Other autoconf goodies (such as
           reenabling -Werror for debug builds, etc). Torbjörn brings in a
           MIDI decoder, which reads from a Timidity process through a pipe.
           Changed playsound to open the audio device to match the properties
           of each sound file, which results in less conversion (and therefore,
           more chance of correct playback).
10022001 - Changed a comment in mod.c to not refer to "the mikmod 
           directory" anymore. Committed Torbjörn's patch for MP3 detection.
           (better late than never). __Sound_strcasecmp() now handles NULL
           strings gracefully, fixing the crash with "playsound bootstrap".
           More work on the SHN decoder.
10012001 - Fixed a memory leak that Torbjörn found in the MOD decoder.
09252001 - More autoconf work. Gave Max Horn write access to the CVS
           repository, so I don't drive him nuts tweaking this thing.  :)
           Fixed a const complaint and some other stuff needed for compilation
           under Visual C++ 6.0 (no, it isn't ported yet). Put the SHN source
           in CVS, even though it isn't ready (and doesn't even compile). Do
           NOT enable it in your build!
09242001 - Thank goodness, Torbjörn came through with the MP3 fix. Apparently
           SMPEG mixes each chunk of decoded data with whatever is already
           in the buffer you give it. I hate that. I'm going to patch SMPEG
           to let the programmer enable and disable that behaviour in a given
           (SMPEG *), since it's just a CPU eater in this case. The _D(())
           macro is now SNDDBG(()), since _D is taken on MacOS X's version of
           gcc (which was bound to happen on some platform sooner than later
           anyhow). Renamed test_sdlsound to playsound, and made it more
           robust in general: fixed potential overflow in audio_callback,
           made it chatter less, made it take multiple files and some other
           command lines. Initial autoconf support, thanks to Max Horn.
09222001 - Torbjörn Andersson strikes again, with a collection of patches.
           First, some cosmetic tweaks for decoders/aiff.c. Next, a MOD player
           based on MikMod. This inspired me to add two more methods to
           Sound_DecoderFunctions: init() and quit(). Third, a fix to
           decoders/mp3.c so that SMPEG won't claim every stream it sees, MP3
           or not. I removed the multiple-streams-per-rwops code, after
           discussion on the mailing list. The init() and quit() methods
           led to the possibility that certain decoders will flag themselves
           as unavailable at runtime, and SDL_sound now handles this.
           Added [LIB|INC]PATH_[OGG|MOD]. Bigendian fixes; now works on
           PowerPC Linux. MikMod tweaks. Changed version to 0.1.2.
09202001 - Torbjörn Andersson submitted several patches: fixed a comment in
           the .WAV decoder (whoops...screwed up my own search-and-replace.
           Hah.), made an attempt at putting multiple sound streams behind
           one RWops (gotta think on that one first), and, most importantly,
           added an AIFF decoder, which is very cool.
09192001 - Added a skeleton decoder source file. Changed voc_read() to
           voc_read_waveform(), so it wouldn't be confused with VOC_read().
           Fixed a byte ordering bug in voc.c (reported as AUDIO_S16LSB, but
           we were swapping byte order of data ourselves. Fixed). Added basic
           .WAV support. Fixed Makefile so that -I. is always first;
           otherwise, a previously installed header might get used for the
           compiles, which is not good. SDL_sound.h now includes SDL_endian.h,
           since SDL.h doesn't, for some reason. Moved version defines in
           SDL_sound.h to top of file so I can find them.  :)
           Changed version to 0.1.1. Committed patch from Tsuyoshi Iguchi to
           fix a segfault (I forgot to put a NULL terminator at the end of
           the available_decoders array), fixing the only bug preventing the
           test program from running on FreeBSD 4.3. Sweet. Added Ogg Vorbis
           decoder. Rewrote the test program's SDL audio callback to be more
           robust (Ogg exposed a nasty bug in it). Fixed a byte-ordering issue
           in the VOC decoder.
09182001 - Implemented MP3 support through SMPEG (not working yet, though) and
           wrote the Reference Counting RWops wrapper. Added other little
           things like the _D(()) macro. Added VOC support, which went up with
           surprisingly little struggle, which means it MUST be leaking
           memory.  :)
09172001 - Changed some overlooked "voice" to "sound". Implemented base API.
           So...tired. Everything's different.  :)
           Also put in a RAW decoder and a simple test program.
09142001 - Changed name to SDL_sound, added Sound_DecodeAll() to spec.
09132001 - Initial spec proposed on SDL mailing list, under name "SDL_voice".
