This is an attempt to give credit to the people who contributed in some way to the mpg123 project.
There are names and email addresses listed. Please use these addresses only to contact contributors with some question about their mpg123 contribution.
You are explicitly not allowed to send them unwanted business offers or to question the quality of their sex life.
--------------------
Being on the list of contributing authors not necessarily means that there
is significant copyright in parts of the source code. There are obviously
contributions of differing complexity. I try to mention people who motivated
changes at least by suggesting some definite code changes, even if their
code did not enter the mpg123 source verbatim. Trivial changes like pointing
out ovbious syntax errors that make compilers cry do not land here.
--------------------
Current maintainers with various sorts of contributions:
Thomas Orgis <thomas@orgis.org>
Patrick Dehne <patrick@steidle.net>
Jonathan Yong <10walls@gmail.com>
Taihei Momma <tmkk@mac.com>
Co-initiator of the revived mpg123 project, but not that involved anymore:
Nicholas J Humfrey <njh@ecs.soton.ac.uk>
Special thanks go to Taihei, the person who keeps the assembly optimisations alive
and takes care of portability to OSX/iOS platforms.
Generic address pointing to the current maintainer (hopefully still works in future in case maintainership will change again): <maintainer@mpg123.org>

View file @ bafb747d
This is the file that contains the terms of use, copying, etc. for the mpg123 distribution package.
Main message, to include in "About ..." boxes, etc:
Copyright (c) 1995-2020 by Michael Hipp and others,
free software under the terms of the LGPL v2.1
There is an attempt to cover the actual list of authors in the AUTHORS file.
Project maintainer since 2006 is Thomas Orgis and many people have contributed
since the Michael Hipp era, but he stays the initial source and it would
be impractical to count them all individually, so it's "and others".
Source files contain the phrase "the mpg123 project" to the same effect
in their license boilerplate; especially those that were added after
maintainership changed. The person mainly responsible for the first version
is usually named in the phrase "initially written by ...".
All files in the distribution that don't carry a license note on their own are
licensed under the terms of the LGPL 2.1; exceptions may apply, especially to
files not in the official distribution but in the revision control repository.

compat: Some compatibility functions and header inclusions.
Basic standard C stuff, that may barely be above/around C89.
The mpg123 code is determined to keep it's legacy. A legacy of old, old UNIX.
It is envisioned to include this compat header instead of any of the "standard" headers, to catch compatibility issues.
So, don't include stdlib.h or string.h ... include compat.h.

matter, although something like //?/UNC/server/some/file could be thrown
around as UTF-8 string, to be converted to a wide \\?\UNC\server\some\file

index: frame index data structure and functions
This is for keeping track of frame positions for accurate seeking.
Now in it's own file, with initial code from frame.c and parse.c .
The idea of the index with a certain amount of entries is to cover
all yet-encountered frame positions with minimal coarseness.
Meaning: At first every frame position is recorded, then, when
the index is full, every second position is trown away to make
space. Next time it is full, the same happens. And so on.
In this manner we maintain a good resolution with the given
maximum index size while covering the whole stream.

optimize: get a grip on the different optimizations
copyright 2007-2013 by the mpg123 project - free software under the terms of the LGPL 2.1
see COPYING and AUTHORS files in distribution or http://mpg123.org
initially written by Thomas Orgis, taking from mpg123.[hc]
for building mpg123 with one optimization only, you have to choose exclusively between
OPT_GENERIC (generic C code for everyone)
OPT_GENERIC_DITHER (same with dithering for 1to1)
OPT_I386 (Intel i386)
OPT_I486 (Somewhat special code for i486; does not work together with others.)
OPT_I586 (Intel Pentium)
OPT_I586_DITHER (Intel Pentium with dithering/noise shaping for enhanced quality)
OPT_MMX (Intel Pentium and compatibles with MMX, fast, but not the best accuracy)
OPT_3DNOW (AMD 3DNow!, K6-2/3, Athlon, compatibles...)
OPT_3DNOW_VINTAGE
OPT_3DNOWEXT (AMD 3DNow! extended, generally Athlon, compatibles...)
OPT_3DNOWEXT_VINTAGE
OPT_SSE
OPT_SSE_VINTAGE
OPT_ALTIVEC (Motorola/IBM PPC with AltiVec under MacOSX)
OPT_X86_64 (x86-64 / AMD64 / Intel 64)
OPT_AVX
or you define OPT_MULTI and give a combination which makes sense (do not include i486, do not mix altivec and x86).
I still have to examine the dynamics of this here together with REAL_IS_FIXED.
Basic point is: Don't use REAL_IS_FIXED with something else than generic or i386.
Also, one should minimize code size by really ensuring that only functions that are really needed are included.
Currently, all generic functions will be always there (to be safe for fallbacks for advanced decoders).
Strictly, at least the synth_1to1 should not be necessary for single-decoder mode.

Hint: BLOCK, MONO_NAME, MONO2STEREO_NAME, SYNTH_NAME and SAMPLE_T as well as WRITE_SAMPLE do vary.
Thomas looked closely at the decode_1to1, decode_2to1 and decode_4to1 contents, seeing that they are too similar to be separate files.
This is what resulted...
Basically, you need one set of these functions for each output sample type.
That currently means signed short, 8bit or float/double; though unsigned short may come, too.
