/*

* CHANGELOG.

*/

05082004 - Started 1.1.0 development branch with code to determine the total

length of a sample (thanks to Wesley, Eric, Wang, and Ahilan!)...

this patch was originally committed to CVS on 10252003, but it is

getting re-merged in the svn repository.

05072004 - Backed out some commits, converted repository to Subversion, and

branched off to a 1.1.0 development tree. Changed MikMod URL...old

one is now a porn site. :(

10252003 - VOC decoder was broken. Now it isn't.

10142003 - Build system fix: acinclude.m4 had some word wrapping badness.

10122003 - Fixed "make dist" behaviour to not packaged generated docs, and

made sure other files are always packaged, regardless of config.

Upped version to 1.0.1.

10102003 - Changed some SDL_Error()s to __Sound_SetError() in new DLS code

to fix linking issues.

10052003 - Fixed memory corruption when freeing DLS instruments,

and bug when timidity is initialized multiple times (Thanks, Sam!).

09252003 - Sam Lantinga added support for DLS instruments to the MIDI decoder.

09132003 - Happy September. Added Speex (.spx) decoder.

08052003 - Fixed MIDI decoder on bigendian systems.

03102003 - Never actually created samplelist_mutex (Thanks, Glenn Maynard!).

01302003 - Patches to make SDL_sound more Visual C happy (Thanks, Eric!).

01122003 - Fix to smpeg.c's rewinding code (Thanks, Eric). Put Visual C 6

project files in CVS, without external binaries (Thanks, Eric).

12212002 - Fixed ogg.c to decode a full buffer at a time instead of one ogg

packet per call, and mikmod has a check during initialization to

prevent a clash with SDL_mixer (Thanks, Eric).

12092002 - Changed Sound_Init()'s call to SDL_Init() to SDL_InitSubSystem(),

to prevent unwanted use of the SDL parachute (thanks, Glenn).

10092002 - Fixed a "make dist" issue and upped version to 1.0.0! Woohoo!

09302002 - libFLAC broke their API (again!) for version 1.0.4. That was the

last straw. I ripped the version detection and obsolete FLAC

support out, so you need libFLAC 1.0.4 for that decoder now (and

they'll probably break the API again for 1.0.5. Argh).

09262002 - Happy September. Fixed SDLCALL issues in SDL_sound.h, so it should

work with Win32/WinCE builds again. I hope. Merged latest altcvt

from Frank into CVS.

08222002 - Borland project files in CVS, thanks to Dominique Louis. There are

project files for C++ Builder 6 (Windows), C++ Builder for Linux

(aka Kylix 3) and Borland's C++ Command line compiler.

08172002 - Timidity memory leak cleanup by Torbjörn.

07292002 - Valgrind cleanups; memory leak patches, etc.

07212002 - done_flag was not being reset between files in playsound, so the

first file would playback, and then any following tracks in a given

run would "finish" immediately. Fixed.

07132002 - More altcvt fixes from Frank Ranostaj.

07122002 - Changed inline keyword to compile universally.

07102002 - Fixed a bug in command line handling in playsound.c. Fixes from

Torbjörn and myself to get flac.c friendly between versions of

libFLAC. Mutex'd a potential race condition in decoders/modplug.c.

FIXME cleanups here and there.

07092002 - Fixed typo in documentation (SDL_sound.h).

07052002 - Cleaned up some stuff in playsound.c, removing some FIXMEs.

Commandline validation is improved, too. FIXME removal in

voc.c; should report i/o errors correctly now. Changed DECLSPEC

to SNDDECLSPEC to prevent SDL conflict, and added SDLCALL support.

Removed all instances of Sound_SetError()...now they are either

__Sound_SetError or BAIL*_MACRO.

07022002 - Added WinCE support pack to website, updated INSTALL with CE info.

More altcvt fixes from Frank Ranostaj.

07012002 - Fixed configure.in to work around bug in older autoconfs. Started

merging Tyler's WinCE (PocketPC) port. Added checks for assert.h

and signal.h to configure.in/config.h.in, and #if HAVE_*_H checks

where appropriate in the code. Moved #include <assert.h> (along

with the HAVE_ASSERT_H check) to SDL_sound_internal.h, and removed

unnecessary #includes from the individual source files. Added

"md_reverb = 1;" to MIKMOD_init(). Modplug got some WinCE-specific

setting tweaks, and some settings maintanance code. configure.in

checks if setbuf() is available.

06292002 - More altcvt fixes from Frank Ranostaj...mostly working now?

06252002 - More altcvt fixes from Frank Ranostaj.

06132002 - Patch from Torbjörn to fix stereo AIFF files.

06212002 - More altcvt fixes from Frank Ranostaj.

06132002 - Patch from Torbjörn to make the WAV decoder more tolerant.

06122002 - Committed some altcvt enhancements from Frank Ranostaj.

06112002 - Fixed some debug messages in smpeg.c and mpglib.c.

06072002 - Manpages! Finally installed Doxygen and scratched together a

Doxyfile. After some revision to physfs.h, we've got a rather

nice API reference.

06062002 - Added URLs for official and unofficial versions of ModPlug in

decoders/modplug.c. Cleaned up some FIXMEs.

05222002 - Torbjörn sent in some more fixes for altcvt: mono to stereo

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".

--ryan. (icculus@clutteredmind.org)
