0.59k: (OF)------- fixed "Accept" header in httpget.c- fixed buffer overflow (causing core dumps) in httpget.c- fixed display of song length- fixed -b (buffer) problem on SGI / IRIX -- it definitely works now- fixed problem when files with different sample rates where played,it now works with -b (buffer), too- fixed order of local variables in decode.c to work around acompiler bug in ultrix- fixed Makefile for ultrix- reverted to old getbits.s (the new one could cause coredumps)- more compact MPEG header display in non-verbose mode- small fixes in buffer code and elsewhere0.59j: (MH)------- added sajber jukebox control interface (it's currently a big hack)(see 'JUKEBOX' file for more)- added simple rewind facility .. (only used by sajber interface at the moment)0.59i: (MH)------------ added front-end (remote) patch from "Brian J. Swetland" <swetland@uiuc.edu>- added OS2 patches from Niclas Lindstrom <nil@wineasy.se>- fixed 'rewind bug'- added patches from Leo Broukhis <leo@zycad.com>- added shuffle patch from Tillmann Steinbrecher <tst@darmstadt.netsurf.de>- added i386-getbits from M.Stekelenburg <m.stekelenburg@student.utwente.nl>- added fallback to 8bit if no 16bit samples support (currently linux only)- added (slightly changed) outburst patchfrom Antti Andreimann <anttix@cyberix.edu.ee>- added 'http accept' patch from Hur TaeSung <saturn@arari.snu.ac.kr>- fixed buffer mode bug0.59h: (MH)------- added '--8bit' option to force 'ULAW 8 BIT' playing- pcm buffer type changed to 'unsigned char *'- plays 2:1 and 4:1 with the real frequency (ie 11025/22050 insteadof 44100)- program (re)sets (changed) frequency for every frame- buffer mode is broken0.59g: (MH)------- added support for MPEG 2.5 (it's a HACK!) .. mpg123 understands and plays2.5 but it does it wrong. (you will hear this!)- Fixed wrong values in BandInfo struct for 32kHz mode- Some performance improvements and minor changes and bug-fixes.- Tried the new imdct from the maplay1.2+ (version 1.81) package. (butit was slightly slower on my system, currently disabled)0.59f: (OF)------- HP-UX audio fix (provided by Damien Clermonte)- Buffering (-b option) hopefully fixed. Please test!0.59e:------- added Audio MPEG 2.0 support (but near untested) (MH)0.59d: (MH)------- minor modifications to dct64_i386.c- removed duplicated dependency 'dct64.o' in Makefile0.59c: (OF)------Another complete rework of the buffer system (-b option)(normally uses mmap(), but it can also use SYSV-ShMem becausemmap() is broken on linux).0.59: (MH)-----extracted dct64() from decode*.c files.some changes to dct64() and decode*.c to allow auto-increment/decrementremoved bit-counter in getbit-functions. Layer3 part2 now counts it itself.0.58: (OF)-----Bugfix: not closing the audio device caused a few samples to be lost.Bugfix: audio_set_rate() was not called (!?!).Additional command line options "--doublespeed" and "--halfspeed"(couldn't find better names). See the manpage.Complete redesign of command line options. See the manpage.Changed the buffer algorithm (-b). I'm not sure whether it's betteror worse now.Supports multiple files on the command line. Pressing Ctrl-C willskip to the next MPEG file, pressing it twice within one secondwill abort mpg123 completely. See the "INTERRUPT" section in themanpage.Support for http URLs. See also the -p option in the manpage.Support for list files. See also the -@ option in the manpage.0.57: (MH)-----Put the downsampling code together with the fullquality decode into one binary. (new options -2to1,-4to1)Optimizations in the dct12.Removed the 'int' version.0.56: (OF)-----Additional command line option "-rs" to try to resync on"broken" MPEG streams (now called "--resync" or "-y").Additional command line option "-b" to use audio output buffering.See the manpage for additional information.Changed a few variable names and some other minor fixes, so thesource compiles more cleanly (without warnings) on mostplatforms (for example, the FreeBSD port compiles withoutwarnings using "-Wall -ansi -pedantic").Makefile changes: moved "solaris" to "solaris-gcc", new target"solaris" (using Sun's SparcWorks cc, faster tha gcc!), newtargets "aix" and "generic".0.55:-----removed some obsolete code from layer3.c (MH)changed scalefac stoing in layer3 (MH)decode_4to1.c added again. Renamed decode_lp.c to decode_2to1.c (MH)(both not optimized .. still expterimental)Minor cleanups and optimizations in layer3. (MH)Removed some (probable) minor bugs. (MH)Changed 2**(...) scaling (and omitted a few muls) (MH)Changed Makefile (OF)Changed dequantize to reorder with a mapping table(you can disable this by undefining MAP in layer3.c) (MH)removed the 'dummy' scale step for mixed mode (MH)Changed copy policy (MH)Modified dequant-reorder-mapping (MH)0.54: (MH)-----Minor changes in the documents ..huffman.c: x->len,y->len removed .. always '15' for the important casesaudio.c: some additions to the SOLARIS audio code0.53b: (OF)------Makefile:Renamed SPARC10 to SUNOS (which is more appropriate).Tested with SunOS 4.1.4 on a SPARCstation SLC, 20 MHz(322% CPU, so no realtime decoding).Added SOLARIS. Tested with Solaris 2.5.1 on an Ultra 1,167 MHz (14% CPU), a SPARCstation 5, 110 MHz (47% CPU),and a SPARCstation 10, 33 MHz (68% CPU).Added FreeBSD. Tested with 2.1.7 on a Pentium-90 (38% CPU)and 2.2 on a Pentium-166 (20% CPU).Added Digital Unix. Tested with DU 3.2 on a DEC 3000/500(Alpha AXP 150 MHz, 33% CPU). Does not support DEC'saudio interface ("AudioFile"), decodes to stdout only.Improved "clean" target to remove core files and editorbackup files.Added "install" target.Added "dist" target to create a .tar.gz file of the sourcedirectory.In the distributed Makefile, all system sections arecommented out. When you type "make" without uncommentingone of the sections, an appropriate error message willbe displayed.audio.cFixed problem when opening /dev/audio on Solaris:I had to remove O_NDELAY, because writing to /dev/audiodidn't block until the requested number of samplescould be written, but instead it wrote only as muchsamples as it was able too. Sounded funny. RemovingO_NDELAY fixed the problem. I don't think that ithurts SunOS either, so I didn't make another #ifdef.common.cFixed bug by adding function finish_output():The decoder writes the audio samples into a buffer, andeach time the buffer is full, it is written to theaudio device (or to stdout). But when the decoding isdone, there are some samples left in the buffer whicharen't written yet -- they were just discarded.This additional function fixes the problem by writingthe remaining samples from the buffer. It is calledimmediately after the main frame loop in mpg123.c.decode*.cFixed compiler warning on symbol "div":Some compilers issue warnings because the symbol div isalready used for something else (see "man div"), so Ichanged it to "divv".layer*.cFunctions do_layer*:Moved the declaration for audio_play_samples intompg123.h. Makes the code cleaner.I moved the variables pcm_samples and pcm_point tocommon.c, so they are shared between all modules. Thiswas necessary because the finish_output() function(see common.c above) needs to access them.Renamed loop variables "i" and "j" to "k" in order tofix compiler warnings for duplicate/hidden symbols(similar to "div" in decode*.c, see above).Changed the preprocessor symbol AUDIOBUFSIZE into aglobal variable "audiobufsize". This makes it possibleto change it by a command line option.layer1.cFixed error in function I_step_one, second parameter:unsigned int scale_index[2][] --> ...[2][SBLIMIT]This caused an error with the DU compiler (which is ok,because [2][] is incorrect according to ANSI). I don'tknow whether [2][SBLIMIT] actually works correctly (Ihave no layer-1 streams to test it), but at least itcompiles without error, and it appears to be correct(looking at the rest of the source). Heaven knows whygcc doesn't issue an error, and what it actually makesfrom it.mpg123.1A simple manual page. Type "nroff -man mpg123.1 | more"to view it, or install it in /usr/local/man/man1 (this isdone automatically by "make install").mpg123.cNew boolean variable "quiet":If this variable is set to TRUE (command line option-q), no messages are printed.***
