1.32.0
------
- build:
-- Move version handling out of configure.ac to ease other build systems.
-- Include "fmt123.h" instead of <fmt123.h> in main API headers to make it more likely the
correct one is included (at least gcc picks the one in the same directory as the
including header first).
-- All headers are build-independent now.
-- Fix build for picky linkers by avoiding definition of wrap_getcpuflags() where it is not
used (spurious linker error to non-exitent getcpuflags(), bug 353).
-- Handle deprecation of C99 detection macro in autoconf 2.70.
-- No use of AC_SYS_LARGEFILE anymore for explicit handling and differing choice for
the libraries and frontend programs.
-- Added --enable-portable and --disable-largefile to configure, removing the other
largefile-related options.
-- Added --disable-components --enable-libmpg123 to only build libmpg123 (and likewise
--enable-libout123, --enable-libout123-modules, --enable-libsyn123) to autoconf
build. CMake build has something similar with BUILD_PROGRAMS and BUILD_LIBOUT123,
which leave only libmpg123 and libsyn123 if disabled). (bug 351)
-- Consistent formatting of ./configure --help with AS_HELP_STRING().
- ports/Sony_PSP: removed
- mpg123:
-- Added --libversion.
-- Added proper A-B looping with terminal control key 'o', renamed
--pauseloop to --presetloop.
-- Really get rid of mpg123_position() usage. (It was all lies before!)
-- Fix terminal progress info when seeking in stopped mode (1.31 regression).
-- Patch up interaction of output buffer with generic remote control, adding
non-interruptible drain after P 3, and dropping buffer on QUIT.
-- Uppercase some generic control replies for consinstency: SILENCE, PROGRESS,
MUTE, UNMUTE
- libmpg123, libout123, libsyn123:
-- Bumped API version for version query functions.
-- Replaced nearly all symbol renames with explicit INT123_ prefix declarations
(intsym.h close to empty now).
- libout123:
-- Add sleep builtin output module (silent, but proper timing).
- libsyn123:
-- Introduced SYN123_PORTABLE_API for an API without off_t and ssize_t
(see NEWS.libsyn123).
- libmpg123:
-- Internal I/O using explicit largefile support via off64_t, lseek64, fallback
to plain 32 bit off_t.
-- Added explicit 64 bit API with 64 suffix (mpg123_tell64(), not mpg123_tell_64()).
This allows full avoidance of ambiguus off_t. The API is always using 64 bit
integers, regardless of internal implementation. (bug 344)
-- Introduced MPG123_PORTABLE_API for an API subset without off_t and
ssize_t.
-- Made mpg123_seek() and friends ignore offset sign for SEEK_END (always seeking
towards beginning, assuming negative offset) to make lseek()-conforming usage
possible. Seeking beyond the end never made sense, so no loss of valid functionality.
- Overall use of INT123_strerror(), trying to use thread-safe strerror_l() if possible.
1.31.3
------
- build:
-- Fix --disable-8bit.
-- Fall back to generic decoder if no yasm for MSVC (bug 346).

The state from 1.32.0 on:
=========================
Yet again, things had to change. The previous state works fine for Unix (adjacent)
sytems, also MinGW stuff on Windows, but it still suffers from off_t being shifty
and not behaving as I expect, even, when people try to build mpg123 with rogue
compilers like MSVC, where off_t is always 32 bits, no largefile support, the whole
idea falls flat. I was pushed to introduce API without off_t where the user can
provide I/O and ensure largefile support and whatnot without being encumbered by
offsets possibly limited to 32 bits.
So this is a new set of API functions with the explicit suffix 64 (not _64), notably
simple functions like
int64_t mpg123_tell64()
but also
int mpg123_reader64()
which takes callbacks that work on int64_t, always. The internal reader code path
in libmpg123 uses either 32 bit or 64 bit offsets, but throughout the library,
it is 64 bits being used as if we supported large files everywhere. And in fact,
we do, if the user provides callbacks that are smart enough.
All existing offset-sensitive code paths are to be rephrased in terms of the new
portable API (portable, because the platform specifics of off_t implementation are
not present). All old API entry points in that regard become wrappers over this
portable API.
The build of libmpg123 needs explicit awareness of largefile support to properly
reason about which wrapper uses which types. It makes use of off_t at default
size and explicit off64_t if available. This results in this for a typical 32 bit
Linux system:
int64_t mpg123_tell64(); // passing on the internal int64_t value
off_t mpg123_tell(); // converting to 32 bit off_t (overflow check)
off_t mpg123_tell_32(); // converting to 32 bit off_t (overflow check)
off64_t mpg123_tell_64(); // converting to 64 bit off_t (no overflow)
A 64 bit Linux would have only these:
int64_t mpg123_tell64(); // passing on the internal int64_t value
off_t mpg123_tell(); // converting to 64 bit off_t (no overflow)
off_t mpg123_tell_64(); // converting to 64 bit off_t (no overflow)
This would look the same on a 32 bit system that also went for fixed 64 bit offsets,
or if you
#define _FILE_OFFSET_BITS 64
during build on a sensitive system. On a funny system that has 64 bit native integers
but still 32 bit off_t, this would also be:
int64_t mpg123_tell64(); // passing on the internal int64_t value
off_t mpg123_tell(); // converting to 32 bit off_t (overflow check)
off_t mpg123_tell_32(); // converting to 32 bit off_t (overflow check)
If this weird system would be also largefile-sensitive, you get the additional
off64_t mpg123_tell_64(); // converting to 64 bit off_t (no overflow)
entry point.
The whole point here: If you stick to mpg123_tell64(), you always can assume
64 bit offsets on any platform. If you also provide your own reader functions, you
can ensure it. Even if we don't properly do large file I/O in libmpg123 itself in
an MSVC build, users can provide it with their application. Providing a full mpg123
program binary along with it in that environment is not a current target. You want
the library.
The point that every platform gets the _64 suffix means that the header can still
do the renaming of function calls if client code defines _FILE_OFFSET_BITS and not
depend on any build-time switches for that. This is what we do officially now with
headers that are not preprocessed anymore, independent of platform.
The build, just assuming int64 is available, needs to know some bits:
- SIZEOF_OFF_T==8: Is the system 64 bit clean, anyway, with 64 bit off_t?
- LFS_LARGEFILE_64: Is there explicit 64 bit I/O for the 32 bit system?
This includes availability of off64_t.
If SIZEOF_OFF_T==8, there will be all 64 bit internal code and two wrappers:
off_t mpg123_tell(); // converting to 64 bit off_t (no overflow)
off_t mpg123_tell_64(); // converting to 64 bit off_t (no overflow)
The second question isn't even needed. If SIZEOF_OFF_T==4, you get
off_t mpg123_tell(); // converting to 32 bit off_t (overflow check)
off_t mpg123_tell_32(); // converting to 32 bit off_t (overflow check)
and the additional decision of LFS_LARGEFILE_64 gives actual 64 bit internal
reader code and the wrapper
off64_t mpg123_tell_64(); // converting to 64 bit off_t (no overflow)
along with that. There is nothing more to know about a system. I do not care how
large your long is. I only ask
1. How big is your off_t?
2. If small, can you give me some off64_t?
That's all what there is to it. The build is not even interested in whether off_t
changes size. This is a detail on the client side that it then gets the off64_t
versions. I do not support a system that allows changing off_t size _without_
off64_t being available.
The state from 1.15.4 on:
=========================
Regarding largefile setup, client apps can be built three ways:
1. _FILE_OFFSET_BITS == 64 (header maps to mpg123_open_64)

The libmpg123 web of reader abstractions
========================================
Somehow the differing ways of getting compressed data into libmpg123 reached
unholy numbers with the years. As keeper of the legacy, I got quite some of that
to keep. There are intersectional layers ... however you might call it.
An attempt to get an overview and be able to refactor that for the glorious
portable API of mpg123 1.32.0.
The frame struct has two parts concerned with input streams.
struct reader *rd; /* pointer to the reading functions */
struct reader_data rdat; /* reader data and state info */
The distinction is blurred a bit: Over time, I added function pointers to
the latter.
1. Basic methods of data input for (seekable) streams
-----------------------------------------------------
These reside in the struct reader_data member of the frame struct (mpg123_handle), so
normally fr->rdat. This is an assortment of (user-supplied) function pointers
and stores the stream position and length. The latter was the initial purpose.
1.1 Reader based around POSIX I/O
---------------------------------
This one relies on some read() and lseek() to give the input bytes. With an
innocent mpg123_open(), you trigger compat_open() and further work on the
resulting fd.
But you can also do mpg123_open_fd() to provide the descriptor yourself. Same
further code path, just no closing.
1.1.1 Timeout read
------------------
The timeout reader is a variant that squeezes into the internal POSIX I/O with
some fcntl() and select() on the file descriptor, and a separate reader callback
stored as fdread().
1.2 Replaced I/O on file descriptor
-----------------------------------
After calling mpg123_replace_reader(), you have your callbacks (or the respective
fallback callback) operating on the file descriptor that could have resulted
from internal opening or been handed over to libmpg123.
1.3 Replaced I/O on custom handle
---------------------------------
This replaces both read() and lseek() with your callbacks and opening is
full external, just the handle being handed over via mpg123_open_handle().
1.4 Replaced I/O on custom handle using 64 bit offsets
------------------------------------------------------
This is to come, the above just with a differing style of callbacks that avoid
off_t. I intend to pack all the above into wrapper code and have this whole
first aspect of differing callbacks removed.
2. Abstractions
---------------
The actual interface to the parser is given by instances of struct reader. This
is usually accessed as fr->rd and contains function pointers to specific routines
like fullread() and head_read(). These access the basic methods behind the scenes.
There is overlap in the functions. The main differentiator is the fullread() call,
which is the next layer of read(). I guess code sharing could be one excuse not
to have each of these as a wholly separate I/O layer implementation.
2.1 READER_STREAM
-----------------
This reader handles a plain possibly seekable input stream. It introduces the
plain_fullread() function which loops over fr->rdat.fdread() until the desired
bytes are aquired or EOF occurs. There is no signal handling. A return value
less than zero is an error and the end, the function returning a short byte
count. This function also advances fr->rdat.filepos if the reader is not
buffered.
2.2 READER_ICY_STREAM
---------------------
This replaces plain_fullread() with icy_fullread(), which looks out for ICY
metadata at the configured interval. It resorts to fr->rdat.fdread() and
plain_fullread() to do its chores.
2.3 READER_FEED
---------------
The reader handling libmpg123 feeder mode. It stuffs data into an internal buffer
and extracts from that, handing out READER_MORE as error to be recovered from
when the client provides more data. It provides a bit of seeking within the
buffer for parsing (look-ahead) purposes, before read data is purged from the
buffer chain.
The actual mid-level reader here is feed_read(), wrapping over the bufferchain data
structre with its methods.
2.4 READER_BUF_STREAM
---------------------
For some reason, I had to add a mode for a stream with some buffering
(MPG123_SEEKBUFFER). Well ... yes, MPEG parsing is just more fun if you can peek
ahead and have a little window of input data to work with. This used to employ
buffered_fullread(), which in turn called fr->rdat.fullread(), which was
plain_fullread() for this variant, and wraped a bufferchain around it.
Now this got its separate buffered_plain_fullread() without the extra function
pointer in fr->rdat.
2.5 READER_BUF_ICY_STREAM
-------------------------
This is the same buffered reader but with buffered_icy_fullread() instead.
3. Control flow for setting up a stream
=======================================
3.1 mpg123_open()
-----------------
Client code just opens a track or possibly called mpg123_replace_reader()
beforehand, which does not change the opening behaviour.
This accesses the given file path via compat_open(), stores a file descriptor,
calls reader stream init which checks seekability (also fetching ID3v1) and
stores file size. This results in one of the READER_*STREAM family.
The lfs_wrap machinery gets triggrered and inserts its callbacks, working
on the prepared wrapper data.
3.2 mpg123_open_fd()
--------------------
This just skips the compat_open() and stores the given file descriptor, assuming
that it works with the configured callbacks. The same dance with stream setup.
The lfs_wrap machinery gets triggrered and inserts its callbacks, working
on the prepared wrapper data.
3.3 mpg123_open_handle()
------------------------
Also skips the opening, stores the handle and does the stream setup.
This shall not trigger callback insertion. The idea is that the user did
call mpg123_reader64() or a wrapper variant of it before. The wrapper code
itself finalizes its work with a call to mpg123_reader64().
Oh, wait. What about the other wrapper calls? Client code calls
mpg123_replace_reader_handle() with its callbacks, be it off_t or off64_t.
This needs to trigger preparation of wrapperdata and installment of wrapper
callbacks via mpg123_reader64(). A subsequent mpg123_open_handle() needs
to store the actual client handle inside the wrapperdata structure and use
the latter as iohandle for stream operation. I need tell apart internal and
external use of mpg123_reader64().
So store a flag for that? Is there another way without introducing yet another
function? Well, the wrapperdata can have two states that fit this scenario:
- not present at all
- present with a respective state set
I want to avoid unnecessary allocation of the wrapperdata (just because I am that
kind of person). So I need to ensure that INT123_wrap_open() when called with
an external handle and not encountering an existing wrapperdata instance, does not
allocate one, but just silently does nothing, as there is nothing to do. Well,
it can check if callbacks are in place. At least that.
3.4 mpg123_open_feed()
----------------------
Prepares for the non-seekable feeder mode, limited stream setup because peeking
at the end won't work.
This does not trigger the wrapper ... except ... should it unregister its
callbacks? No. The code path of the feeder is separate enough that it does
not interfere.
4. Plan
=======
Keep the abstractions in readers.c, move all variants of POSIX-like callback stuff
into the wrapper section (lfs_wrap.c for now). In theory, the buffer chain for
the feeder could also be moved into a variant hidden behind mpg123_reader64(). Maybe
in the future. At some point.
I don't want any mpg123 internals regarding the frame struct in the wrapper
implementation. So maybe lfs_wrap.c only offers wrapper setup as such and
libmpg123.c does the actual stream opening? No. The explicit largefile stuff
needs to be handled (O_LARGEFILE). But the further stream setup ... that
should happen in mpg123_open() and friends, after reader handle setup.
I still need fr->rdat.flags for selecting buffered etc., but not for
READER_FD_OPENEND or READER_NONBLOCK.
Both fr->rdat.fullread and fr->rdat.fdread are gone now. The picture is getting
clearer.
I made the static functions fdread() and fdseek() robust against missing
callbacks. It's a question if we'd rather want to catch those earlier, though.

.TH mpg123 1 "11 Jul 2022"
.SH NAME
mpg123 \- play audio MPEG 1.0/2.0/2.5 stream (layers 1, 2 and 3)
.SH SYNOPSIS
.B mpg123
[
.I options
]
.IR file-or-URL ...
.SH DESCRIPTION
.B mpg123
reads one or more
.IR file\^ s
(or standard input if ``\-'' is specified) or
.IR URL\^ s
and plays them on the audio device (default) or
outputs them to stdout.
.IR file\^ / URL
is assumed to be an MPEG audio bit stream.
.SH OPERANDS
The following operands are supported:
.TP 8
.IR file (s)
The path name(s) of one or more input files. They must be
valid MPEG-1.0/2.0/2.5 audio layer 1, 2 or 3 bit streams.
If a dash ``\-'' is specified, MPEG data will
be read from the standard input. Furthermore, any name
starting with ``http://'' or ``https://'' is recognized as
.I URL
(see next section), while a leading ``file://'' is being stripped for
normal local file access, for consistency (since mpg123 1.30.1).
.SH OPTIONS
.B mpg123
options may be either the traditional POSIX one letter options,
or the GNU style long options. POSIX style options start with a
single ``\-'', while GNU long options start with ``\-\^\-''.
Option arguments (if needed) follow separated by whitespace (not ``='').
Note that some options can be absent from your installation when disabled in the build process.
.SH INPUT OPTIONS
.TP
\fB\-k \fInum\fR, \fB\-\^\-skip \fInum
Skip first
.I num
frames. By default the decoding starts at the first frame.
.TP
\fB\-n \fInum\fR, \fB\-\^\-frames \fInum
Decode only
.I num
frames. By default the complete stream is decoded.
.TP
.BR \-\-fuzzy
Enable fuzzy seeks (guessing byte offsets or using approximate seek points from Xing TOC).
Without that, seeks need a first scan through the file before they can jump at positions.
You can decide here: sample-accurate operation with gapless features or faster (fuzzy) seeking.
.TP
.BR \-y ", " \-\^\-no\-resync
Do NOT try to resync and continue decoding if an error occurs in
the input file. Normally,
.B mpg123
tries to keep the playback alive at all costs, including skipping invalid material and searching new header when something goes wrong.
With this switch you can make it bail out on data errors
(and perhaps spare your ears a bad time). Note that this switch has been renamed from \-\-resync.
The old name still works, but is not advertised or recommended to use (subject to removal in future).
.TP
.BR \-F ", " \-\^\-no\-frankenstein
Disable support for Frankenstein streams. Normally, mpg123 stays true to the concept of MPEG audio being
just a concatenation of MPEG frames. It will continue decoding even if the type of MPEG frames varies
wildly. With this switch, it will only decode the input as long as it does not change its character
(from layer I to layer III, changing sampling rate, from mono to stereo), silently assuming end of
stream on such occasion. The switch also stops decoding of compatible MPEG frames if there was an
Info frame (Xing header, Lame tag) that contained a length of the track in MPEG frames.
This comes a bit closer to the notion of a MP3 file as a defined collection
of MPEG frames that belong together, but gets rid of the flexibility that can be fun at times but
mostly is hell for the programmer of the parser and decoder ...
.TP
\fB\-\^\-network \fI backend
Select network backend (helper program), choices are usually auto, wget, and curl.
Auto means to try the first available backend.
.TP
\fB\-\^-resync\-limit \fIbytes\fR
Set number of bytes to search for valid MPEG data once lost in stream; <0 means search whole stream.
If you know there are huge chunks of invalid data in your files... here is your hammer.
Note: Only since version 1.14 this also increases the amount of junk skipped on beginning.
.TP
\fB\-u \fIauth\fR, \fB\-\^\-auth \fIauth
HTTP authentication to use when receiving files via HTTP.
The format used is user:password. Mpg123 will clear this quickly, but it may still appear
in sight of other users or even just in your shell history. You may seek alternative ways
to specify that to your network backend.
.TP
\fB\-\^\-auth-file \fIauthfile
Provide the authentication info via given file instead of command line directly.
.TP
\fB\-\^\-ignore\-mime
Ignore MIME types given by HTTP server. If you know better and want mpg123
to decode something the server thinks is image/png, then just do it.
.TP
\fB\-\^\-no\-icy\-meta
Do not accept ICY meta data.
.TP
\fB\-\^-streamdump \fIfilename\fR
Dump a copy of the input data (as read by libmpg123) to the given file.
This enables you to store a web stream to disk while playing, or just create
a concatenation of the local files you play for ... why not?
.TP
\fB\-\^-icy\-interval \fIbytes\fR
This setting enables you to play a stream dump containing ICY metadata at the given
interval in bytes (the value of the icy-metaint HTTP response header). Without it,
such a stream will play, but will cause regular decoding glitches with resync.
.TP
\fB\-\^\-no\-seekbuffer
Disable the default micro-buffering of non-seekable streams that gives the
parser a safer footing.
.TP
\fB\-@ \fIfile\fR, \fB\-\^\-list \fIfile
Read filenames and/or URLs of MPEG audio streams from the specified
.I file
in addition to the ones specified on the command line (if any).
Note that
.I file
can be either an ordinary file, a dash ``\-'' to indicate that
a list of filenames/URLs is to be read from the standard input,
or an URL pointing to a an appropriate list file. Note: only
one
.B \-@
option can be used (if more than one is specified, only the
last one will be recognized). Furthermore, for HTTP resources, the
MIME type information will be used to re-open an actual MPEG stream as
such instead of treating it as playlist file. So you could just always
use
.B \-@
for web resources without bothering if it is a playlist or already the resolved
stream address.
.TP
\fB\-l \fIn\fR, \fB\-\^\-listentry \fIn
Of the playlist, play specified entry only.
.I n
is the number of entry starting at 1. A value of 0 is the default and means playing the whole list, a negative value means showing of the list of titles with their numbers...
.TP
\fB\-\^\-continue
Enable playlist continuation mode. This changes frame skipping to apply only to the first track and also continues to play following tracks in playlist after the selected one. Also, the option to play a number of frames only applies to the whole playlist. Basically, this tries to treat the playlist more like one big stream (like, an audio book).
The current track number in list (1-based) and frame number (0-based) are printed at exit (useful if you interrupted playback and want to continue later).
Note that the continuation info is printed to standard output unless the switch for piping audio data to standard out is used. Also, it really makes sense to work with actual playlist files instead of lists of file names as arguments, to keep track positions consistent.
.TP
\fB\-\-loop \fItimes\fR
for looping track(s) a certain number of times, < 0 means infinite loop (not with \-\-random!).
.TP
.BR \-\-keep\-open
For remote control mode: Keep loaded file open after reaching end.
.TP
\fB\-\-timeout \fIseconds\fR
Timeout in (integer) seconds before declaring a stream dead (if <= 0, wait forever).
.TP
.BR \-z ", " \-\^\-shuffle
Shuffle play. Randomly shuffles the order of files specified on the command
line, or in the list file.
.TP
.BR \-Z ", " \-\-random
Continuous random play. Keeps picking a random file from the command line
or the play list. Unlike shuffle play above, random play never ends, and
plays individual songs more than once.
.TP
\fB\-i, \-\^-index
Index / scan through the track before playback.
This fills the index table for seeking (if enabled in libmpg123) and may make the operating system cache the file contents for smoother operating on playback.
.TP
\fB\-\-index\-size \fIsize\fR
Set the number of entries in the seek frame index table.
.TP
\fB\-\-preframes \fInum\fR
Set the number of frames to be read as lead-in before a seeked-to position.
This serves to fill the layer 3 bit reservoir, which is needed to faithfully reproduce a certain sample at a certain position.
Note that for layer 3, a minimum of 1 is enforced (because of frame overlap), and for layer 1 and 2, this is limited to 2 (no bit reservoir in that case, but engine spin-up anyway).
.SH OUTPUT and PROCESSING OPTIONS
.TP
\fB\-o \fImodule\fR, \fB\-\^\-output \fImodule\fR
Select audio output module. You can provide a comma-separated list to use the first one that works.
Also see \fB\-a\fR.
.TP
\fB\-\^\-list\-modules
List the available modules.
.TP
\fB\-\^\-list\-devices
List the available output devices for given output module. If there is no functionality
to list devices in the chosen module, an error will be printed and mpg123 will exit with
a non-zero code.
.TP
\fB\-a \fIdev\fR, \fB\-\^\-audiodevice \fIdev
Specify the audio device to use. The default as well as the possible values
depend on the active output. For the JACK output, a comma-separated list
of ports to connect to (for each channel) can be specified.
.TP
.BR \-s ", " \-\^\-stdout
The decoded audio samples are written to standard output,
instead of playing them through the audio device. This
option must be used if your audio hardware is not supported
by
.BR mpg123 .
The output format per default is raw (headerless) linear PCM audio data,
16 bit, stereo, host byte order (you can force mono or 8bit).
.TP
\fB\-O \fIfile\fR, \fB\-\^\-outfile
Write raw output into a file (instead of simply redirecting standard output to a file with the shell).
.TP
\fB\-w \fIfile\fR, \fB\-\^\-wav
Write output as WAV file. This will cause the MPEG stream to be decoded
and saved as file
.I file
, or standard output if
.I -
is used as file name. You can also use
.I --au
and
.I --cdr
for AU and CDR format, respectively. Note that WAV/AU writing to non-seekable files, or redirected stdout, needs some thought. Since 1.16.0, the logic changed to writing the header with the first actual data. This avoids spurious WAV headers in a pipe, for example. The result of decoding nothing to WAV/AU is a file consisting just of the header when it is seekable and really nothing when not (not even a header). Correctly writing data with prophetic headers to stdout is no easy business.
.TP
\fB\-\^\-au \fIfile
Does not play the MPEG file but writes it to
.I file
in SUN audio format. If \- is used as the filename, the AU file is
written to stdout. See paragraph about WAV writing for header fun with non-seekable streams.
.TP
\fB\-\^\-cdr \fIfile
Does not play the MPEG file but writes it to
.I file
as a CDR file. If \- is used as the filename, the CDR file is written
to stdout.
.TP
.BR \-\-reopen
Forces reopen of the audiodevice after ever song
.TP
.BR \-\-cpu\ \fIdecoder\-type
Selects a certain decoder (optimized for specific CPU), for example i586 or MMX.
The list of available decoders can vary; depending on the build and what your CPU supports.
This option is only available when the build actually includes several optimized decoders.
.TP
.BR \-\-test\-cpu
Tests your CPU and prints a list of possible choices for \-\-cpu.
.TP
.BR \-\-list\-cpu
Lists all available decoder choices, regardless of support by your CPU.
.TP
\fB\-g \fIgain\fR, \fB\-\^\-gain \fIgain
[DEPRECATED] Set audio hardware output gain (default: don't change). The unit of the gain value is hardware and output module dependent.
(This parameter is only provided for backwards compatibility and may be removed in the future without prior notice. Use the audio player for playing and a mixer app for mixing, UNIX style!)
.TP
\fB\-f \fIfactor\fR, \fB\-\^\-scale \fIfactor
Change scale factor (default: 32768).
.TP
.BR \-\-rva-mix,\ \-\-rva-radio
Enable RVA (relative volume adjustment) using the values stored for ReplayGain radio mode / mix mode with all tracks roughly equal loudness.
The first valid information found in ID3V2 Tags (Comment named RVA or the RVA2 frame) or ReplayGain header in Lame/Info Tag is used.
.TP
.BR \-\-rva-album,\ \-\-rva-audiophile
Enable RVA (relative volume adjustment) using the values stored for ReplayGain audiophile mode / album mode with usually the effect of adjusting album loudness but keeping relative loudness inside album.
The first valid information found in ID3V2 Tags (Comment named RVA_ALBUM or the RVA2 frame) or ReplayGain header in Lame/Info Tag is used.
.TP
.BR \-0 ", " \-\^\-single0 "; " \-1 ", " \-\^\-single1
Decode only channel 0 (left) or channel 1 (right),
respectively. These options are available for
stereo MPEG streams only.
.TP
.BR \-m ", " \-\^\-mono ", " \-\^\-mix ", " \-\^\-singlemix
Mix both channels / decode mono. It takes less
CPU time than full stereo decoding.
.TP
.BR \-\-stereo
Force stereo output
.TP
\fB\-r \fIrate\fR, \fB\-\^\-rate \fIrate
Set sample rate (default: automatic). You may want to
change this if you need a constant bitrate independent of
the mpeg stream rate. mpg123 automagically converts the
rate. You should then combine this with \-\-stereo or \-\-mono.
.TP
\fB\-\^\-resample \fImethod
Set resampling method to employ if forcing an output rate. Choices (case-insensitive) are NtoM,
dirty, and fine. The fine resampler is the default. It employs libsyn123's low-latency fairly
efficient resampler to postprocess the output from libmpg123 instead of the fast but very crude
NtoM decoder (drop sample method) that mpg123 offers since decades. If you are really low on
CPU time, choose NtoM, as the resampler usually needs more time than the MPEG decoder itself.
The mpg123 program is smart enough to combine the 2to1 or 4to1 downsampling modes with the
postprocessing for extreme downsampling.
.TP
.BR \-2 ", " \-\^\-2to1 "; " \-4 ", " \-\^\-4to1
Performs a downsampling of ratio 2:1 (22 kHz from 44.1 kHz) or 4:1 (11 kHz)
on the output stream, respectively. Saves some CPU cycles, but of course throws away
the high frequencies, as the decoder does not bother producing them.
.TP
.BR \-\-pitch\ \fIvalue
Set a pitch change (speedup/down, 0 is neutral; 0.05 is 5% speedup). When not enforcing an
output rate, this changes the output sampling rate, so it only works in the range your audio
system/hardware supports. When you combine this with a fixed output rate, it modifies a
software resampling ratio instead.
.TP
.BR \-\-8bit
Forces 8bit output
.TP
\fB\-\^\-float
Forces f32 encoding
.TP
\fB\-e \fIenc\fR, \fB\-\^\-encoding \fIenc
Choose output sample encoding. Possible values look like f32 (32-bit floating point), s32 (32-bit signed integer), u32 (32-bit unsigned integer) and the variants with different numbers of bits (s24, u24, s16, u16, s8, u8) and also special variants like ulaw and alaw 8-bit.
See the output of mpg123's longhelp for actually available encodings.
.TP
\fB\-d \fIn\fR, \fB\-\^\-doublespeed \fIn
Only play every
.IR n 'th
frame. This will cause the MPEG stream
to be played
.I n
times faster, which can be used for special
effects. Can also be combined with the
.B \-\^\-halfspeed
option to play 3 out of 4 frames etc. Don't expect great
sound quality when using this option.
.TP
\fB\-h \fIn\fR, \fB\-\^\-halfspeed \fIn
Play each frame
.I n
times. This will cause the MPEG stream
to be played at
.IR 1 / n 'th
speed (n times slower), which can be
used for special effects. Can also be combined with the
.B \-\^\-doublespeed
option to double every third frame or things like that.
Don't expect great sound quality when using this option.
.TP
\fB\-E \fIfile\fR, \fB\-\^\-equalizer
Enables equalization, taken from
.IR file .
The file needs to contain 32 lines of data, additional comment lines may
be prefixed with
.IR # .
Each data line consists of two floating-point entries, separated by
whitespace. They specify the multipliers for left and right channel of
a certain frequency band, respectively. The first line corresponds to the
lowest, the 32nd to the highest frequency band.
Note that you can control the equalizer interactively with the generic control interface.
Also note that these are the 32 bands of the MPEG codec, not spaced like you
would see for a usual graphic equalizer. The upside is that there is zero computational
cost in addition to decoding. The downside is that you roughly have bass in band 0,
(upper) mids in band 1, treble in all others.
.TP
\fB\-\^\-gapless
Enable code that cuts (junk) samples at beginning and end of tracks, enabling gapless transitions between MPEG files when encoder padding and codec delays would prevent it.
This is enabled per default beginning with mpg123 version 1.0.0 .
.TP
\fB\-\^\-no\-gapless
Disable the gapless code. That gives you MP3 decodings that include encoder delay and padding plus mpg123's decoder delay.
.TP
\fB\-\^\-no\-infoframe
Do not parse the Xing/Lame/VBR/Info frame, decode it instead just like a stupid old MP3 hardware player.
This implies disabling of gapless playback as the necessary information is in said metadata frame.
.TP
\fB\-D \fIn\fR, \fB\-\-delay \fIn
Insert a delay of \fIn\fR seconds before each track.
.TP
.BR "\-o h" ", " \-\^\-headphones
Direct audio output to the headphone connector (some hardware only; AIX, HP, SUN).
.TP
.BR "\-o s" ", " \-\^\-speaker
Direct audio output to the speaker (some hardware only; AIX, HP, SUN).
.TP
.BR "\-o l" ", " \-\^\-lineout
Direct audio output to the line-out connector (some hardware only; AIX, HP, SUN).
.TP
\fB\-b \fIsize\fR, \fB\-\^\-buffer \fIsize
Use an audio output buffer of
.I size
Kbytes. This is useful to bypass short periods of heavy
system activity, which would normally cause the audio output
to be interrupted.
You should specify a buffer size of at least 1024
(i.e. 1 Mb, which equals about 6 seconds of audio data) or more;
less than about 300 does not make much sense. The default is 0,
which turns buffering off.
.TP
\fB\-\^\-preload \fIfraction
Wait for the buffer to be filled to
.I fraction
before starting playback (fraction between 0 and 1). You can tune this prebuffering to either get faster sound to your ears or safer uninterrupted web radio.
Default is 0.2 (wait for 20 % of buffer to be full, changed from 1 in version 1.23).
.TP
\fB\-\^\-devbuffer \fIseconds
Set device buffer in seconds; <= 0 means default value. This is the small buffer between the
application and the audio backend, possibly directly related to hardware buffers.
.TP
\fB\-\^\-smooth
Keep buffer over track boundaries -- meaning, do not empty the buffer between tracks for possibly some added smoothness.
.SH MISC OPTIONS
.TP
.BR \-t ", " \-\^\-test
Test mode. The audio stream is decoded, but no output occurs.
.TP
.BR \-c ", " \-\^\-check
Check for filter range violations (clipping), and report them for each frame
if any occur.
.TP
.BR \-v ", " \-\^\-verbose
Increase the verbosity level. For example, displays the frame
numbers during decoding.
.TP
.BR \-q ", " \-\^\-quiet
Quiet. Suppress diagnostic messages.
.TP
.BR \-C ", " \-\^\-control
Enable terminal control keys. This is enabled automatically if a terminal is detected.
By default use 's' or the space bar to stop/restart (pause, unpause) playback, 'f' to jump forward to the next song, 'b' to jump back to the
beginning of the song, ',' to rewind, '.' to fast forward, and 'q' to quit.
Type 'h' for a full list of available controls.
.TP
\fB\-\^\-no\-control
Disable terminal control even if terminal is detected.
.TP
\fB\-\^\-title
In an xterm, rxvt, screen, iris-ansi (compatible, TERM environment variable is examined), change the window's title to the name of song currently
playing.
.TP
\fB\-\^\-pauseloop \fIseconds
Set the length of the loop interval in terminal control paused mode, away from the default of 0.5 seconds, as a floating
point number.
.TP
\fB\-\^\-name \fIname
Set the name of this instance, possibly used in various places. This sets the client name for JACK output.
.TP
\fB\-\^\-long\-tag
Display ID3 tag info always in long format with one line per item (artist, title, ...)
.TP
.BR \-\-utf8
Regardless of environment, print metadata in UTF-8 (otherwise, when not using UTF-8 locale, you'll get ASCII stripdown).
.TP
.BR \-R ", " \-\^\-remote
Activate generic control interface.
.B mpg123
will then read and execute commands from stdin. Basic usage is ``load <filename> '' to play some file and the obvious ``pause'', ``command.
``jump <frame>'' will jump/seek to a given point (MPEG frame number).
Issue ``help'' to get a full list of commands and syntax.
.TP
.BR \-\^\-remote\-err
Print responses for generic control mode to standard error, not standard out.
This is automatically triggered when using \fB-s\fR.
.TP
\fB\-\-fifo \fIpath
Create a fifo / named pipe on the given path and use that for reading commands instead of standard input.
.TP
\fB\-\^\-aggressive
Tries to get higher priority
.TP
.BR \-T ", " \-\-realtime
Tries to gain realtime priority. This option usually requires root
privileges to have any effect.
.TP
.BR \-? ", " \-\^\-help
Shows short usage instructions.
.TP
.BR \-\^\-longhelp
Shows long usage instructions.
.TP
.BR \-\^\-version
Print the version string.
.SH HTTP SUPPORT
In addition to reading MPEG audio streams from ordinary
files and from the standard input,
.B mpg123
supports retrieval of MPEG audio streams or playlists via the HTTP protocol,
which is used in the World Wide Web (WWW). Such files are
specified using a so-called URL, which starts with http:// or https://.
When a file with that prefix is encountered,
.B mpg123
since 1.30.0 will by default call an external helper program (either
.BR wget (1)
or
.BR curl (1),
see the
.B \-\^\-network
option)
to retrieve the resource. You can configure access via a proxy
server using the standard environment variables those programs support. The
.BR \-\^\-proxy
option that
.B mpg123
before 1.30.0 used for its internal network code is gone
in the default build now and will probably disappear for good with 1.31.1.
.P
Note that, in order to play MPEG audio files from a WWW
server, it is necessary that the connection to that server
is fast enough. For example, a 128 kbit/s MPEG file
requires the network connection to be at least 128 kbit/s
(16 kbyte/s) plus protocol overhead. If you suffer from
short network outages, you should try the
.B \-b
option (buffer) to bypass such outages. If your network
connection is generally not fast enough to retrieve MPEG
audio files in realtime, you can first download the files
to your local harddisk (e.g. using
.BR wget (1))
and then play them from there.
.P
Streams with embedded ICY metadata are supported, the interval being communicated via HTTP
headers or \fB\-\^\-icy-interval\fR.
.SH INTERRUPT
When in terminal control mode, you can quit via pressing the q key,
while any time you can abort
.B mpg123
by pressing Ctrl-C. If not in terminal control mode, this will
skip to the next file (if any). If you want to abort playing immediately
in that case, press Ctrl-C twice in short succession (within about one second).
.P
Note that the result of quitting
.B mpg123
pressing Ctrl-C might not be audible
immediately, due to audio data buffering in the audio device.
This delay is system dependent, but it is usually not more
than one or two seconds.
.SH PLAYBACK STATUS LINE
In verbose mode, mpg123 updates a line with various information centering around
the current playback position. On any decent terminal, the line also works
as a progress bar in the current file by reversing video for a fraction of the
line according to the current position. An example for a full line is this:
> 0291+0955 00:01.68+00:28.22 [00:05.30] mix 100=085 192 kb/s 576 B acc 18 clip p+0.014
The information consists of, in order:
.TP
.BR >
single-character playback state (``>'' for playing, ``='' for pausing/looping, ``_'' for stopped)
.TP
.BR 0291+0955
current frame offset and number of remaining frames after the plus sign
.TP
.BR 00:01.68+00:28.22
current position from and remaining time in human terms
(hours, minutes, seconds)
.TP
.BR [00:05.30]
fill of the output buffer in terms of playback time, if the buffer is enabled
.TP
.BR mix
selected RVA mode (possible values: mix, alb (album), and \-\^\-\^\- (neutral, off))
.TP
.BR 100=085
set volume and the RVA-modified effective volume after the equal sign
.TP
.BR 192\ kb/s
current bitrate
.TP
.BR 576\ B
size of current frame in bytes
.TP
.BR acc
if positions are accurate, possible values are ``acc'' for accurate positions or ``fuz'' for fuzzy
(with guessed byte offsets using mean frame size)
.TP
.BR 18\ clip
amount of clipped samples, non-zero only if decoder reports that
(generic does, some optimized ones not)
.TP
.BR p+0.014
pitch change (increased/decreased playback sampling rate on user request)
.SH NOTES
MPEG audio decoding requires a good deal of CPU performance,
especially layer-3. To decode it in realtime, you should
have at least an i486DX4, Pentium, Alpha, SuperSparc or equivalent
processor. You can also use the
.B -m
option to decode mono only, which reduces the CPU load
somewhat for layer-3 streams. See also the
.BR \-2 " and " \-4
options.
.P
If everything else fails, have mpg123 decode to a file
and then use an appropriate utility to play that file with less CPU load.
Most probably you can configure mpg123 to produce a format suitable
for your audio device (see above about encodings and sampling rates).
.P
If your system is generally fast enough to decode in
realtime, but there are sometimes periods of heavy
system load (such as cronjobs, users logging in remotely,
starting of ``big'' programs etc.) causing the
audio output to be interrupted, then you should use
the
.B \-b
option to use a buffer of reasonable size (at least 1000 Kbytes).
.SH EXIT CODE
.P
Up to version 1.25.x, mpg123 always returned exit code 0 also for
complete junk on the input side. Fatal errors were only considered
for output. With version 1.26.0, this changed to the behaviour
described below.
.P
When not using the remote control interface (which returns input
errors as text messages), the process exit code is zero (success)
only if all tracks in a playlist had at least one frame parsed,
even if it did not decode cleanly, or
are empty, MPEG-wise (perhaps only metadata, or really an empty file).
When you decode nothing, nothing is the result and that is fine. When
a track later aborts because of parser errors or breakdown of the
network communication, this is treated as end of a track, but does
not make the process as such fail. One really bad (or non-existing)
stream in the playlist results in a non-zero error code, consistent
with other UNIX tools.
.P
An error in audio output results in the process ending with a
non-zero exit code immediately, regardless of how much data has
been successfully played before. The forgiveness is only on the
input side.
.SH BUGS
.P
Mostly MPEG-1 layer 2 and 3 are tested in real life.
Please report any issues and provide test files to help fixing them.
.P
No CRC error checking is performed. But the decoder is built and tested
to behave nicely with damaged streams. Mostly, damaged frames will just be
silent.
.P
Some platforms lack audio hardware support; you may be able to use the
.B -s
switch to feed the decoded data to a program that can play it on your audio device.

.SH SYNOPSIS
\fBcat \fRaudio.raw \fR| \fBout123 \fR[ \fR- \fR] [ \fIoptions \fR ]
\fBout123 \fR[ \fIoptions \fR] \fIfilename \fR[ \fIfilename \fR... ]

.SH DESCRIPTION
.B out123
reads raw PCM data (in host byte order) from standard input
and plays it on the audio device specified by given options.
Alternatively, it can generate periodic or random signals for playback
itself.
.SH OPTIONS
.B out123
options may be either the traditional POSIX one letter options,
or the GNU style long options. POSIX style options start with a
single '\-', while GNU long options start with '\-\^\-'.
Option arguments (if needed) follow separated by whitespace (not '=').
Note that some options can be absent from your installation when disabled in the build process.
.TP
\fB\-\^\-name \fIname
Set the name of this instance, possibly used in various places. This sets the client name for JACK output.
.TP
\fB\-o \fImodule\fR, \-\^\-\fBoutput \fImodule\fR
Select audio output module. You can provide a comma-separated list to use the first one that works.
Also see \fB\-a\fR.
.TP
\fB\-\^\-list\-modules
List the available modules.
.TP
\fB\-\^\-list\-devices
List the available output devices for given output module. If there is no functionality
to list devices in the chosen module, an error will be printed and out123 will exit with
a non-zero code.
.TP
\fB\-a \fIdev\fR, \fB\-\^\-audiodevice \fIdev
Specify the audio device to use. The default as well as the possible values
depend on the active output. For the JACK output, a comma-separated list
of ports to connect to (for each channel) can be specified.
.TP
.BR \-s ", " \-\^\-stdout
The audio samples are written to standard output,
instead of playing them through the audio device.
The output format is the same as the input ... so in this mode,
.B out123
acts similar the standard tool \fB cat\fR, possibly with some conversions
involved.
This shortcut is equivalent to '-o raw -a -'.
.TP
.BR \-S ", " \-\^\-STDOUT
This variant additionally writes the data to stdout, while still
playing it on the output device. So it is more like some flavour of
\fBtee\fR than a \fBcat\fR.
.TP
\fB\-O \fIfile\fR, \fB\-\^\-outfile
Write raw output into a file (instead of simply redirecting standard output to a file with the shell).
This shortcut is equivalent to '-o raw -a \fIfile\fR'.
.TP
\fB\-w \fIfile\fR, \fB\-\^\-wav
Write output as WAV file
.I file
, or standard output if
.I -
is or the empty string used as file name. You can also use
.I --au
and
.I --cdr
for AU and CDR format, respectively. Note that WAV/AU writing to non-seekable files or redirected stdout needs some thought. The header is written with the first actual data. The result of decoding nothing to WAV/AU is a file consisting just of the header when it is seekable and really nothing when not (not even a header). Correctly writing data with prophetic headers to stdout is no easy business.
This shortcut is equivalent to '-o wav -a \fIfile\fR'.
.TP
\fB\-\^\-au \fIfile
Write to
.I file
in SUN audio format. If \- or the empty string is used as the filename, the AU file is
written to stdout. See paragraph about WAV writing for header fun with non-seekable streams.
This shortcut is equivalent to '-o au -a \fIfile\fR'.
.TP
\fB\-\^\-cdr \fIfile
Write to
.I file
as a CDR (CD-ROM audio, more correctly CDDA for Compact Disc Digital Audio).
If \- is or the empty string used as the filename, the CDR file is written
to stdout.
This shortcut is equivalent to '-o cdr -a \fIfile\fR'.
.TP
\fB\-r \fIrate\fR, \fB\-\^\-rate \fIrate
Set sample rate in Hz (default: 44100). If this does not match the actual input
sampling rate, you get changed pitch. Might be intentional;-)
.TP
\fB\-R \fIrate\fR, \fB\-\^\-inputrate \fIrate
Set input sample rate to a different value. This triggers resampling if the output
rate is indeed different. See \fB\-\^\-resample\fR.
.TP
\fB\-\^\-speed \fIfactor
Speed up/down playback by that factor using resampling. See \fB\-\^\-resample\fR.
.TP
\fB\-\^\-resample \fImethod
This chooses the method for resampling between differing sampling rates or to apply
a change in tempo. You can choose between two variants of the syn123 resampler: fine
(the default) and dirty. The fine one features 108 dB dynamic range and at worst-case 84%
bandwidth. The dirty one uses a bit less CPU time (not that much, though) by reducing
the dynamic range to 72 dB with worst-case bandwidth of 85%. The exact properties vary
with the sampling rate ratio, as there is interpolation of filter coefficients involved.
.TP
\fB\-c \fIcount\fR, \fB\-\^\-channels \fIcount
Set channel count to given value.
.TP
\fB\-C \fIcount\fR, \fB\-\^\-inputch \fIcount
Set input channel count to a differnt value than for output. This probably means you want
some remixing. Also see \fB\-\^\-mix\fR.
.TP
\fB\-e \fIenc\fR, \fB\-\^\-encoding \fIenc
Choose output sample encoding. Possible values look like f32 (32-bit floating point), s32 (32-bit signed integer), u32 (32-bit unsigned integer) and the variants with different numbers of bits (s24, u24, s16, u16, s8, u8) and also special variants like ulaw and alaw 8-bit.
See the output of \fBout123\fR's longhelp for actually available encodings.
Default is s16.
.TP
\fB\-\^\-endian \fIchoice
Select output endianess (byte order). Choice is big, little, or native, which is the default.
The processing can only work in native mode, so you need to specify input or output byte order
if that does not match your machine. This also sets the input endianess if that is
not set separately. See also \fB\-\^\-inputend\fR and \fB\-\^\-byteswap\fR.
.TP
\fB\-E \fIenc\fR, \fB\-\^\-inputenc \fIenc
Specify input encoding different from output encoding for conversion.
.TP
\fB\-\^\-inputend \fIchoice
Select input endianess (byte order). By default it is the same as output byte order.
See \fB\-\^\-endian\fR.
.TP
.BR \-\^\-byteswap
A switch to trigger swapping of byte order just before output, after any other transformations.
This works on top of any endianess you specify with
.TP
.BR \-m ", " \-\^\-mono "
Set for single-channel audio (default is two channels, stereo).
.TP
.BR \-\-stereo
Select stereo output (2 channels, default).
.TP
.BR \-\^\-list\-encodings
List known encoding short and long names to standard output.
.TP
\fB\-\^\-mix \fImatrix
Specify a mixing matrix between input and output channels as linear factors, comma separated list for
the input channel factors for output channel 1, then output channel 2, and so forth.
The default is a unit matrix if channel counts match, so for 3 channels the equivalent of
'\-\^\-mix 1,0,0,0,1,0,0,0,1'. For stereo to mono conversion, the default is mixing of
both channels with halved amplitude, so '\-\^\-mix 0.5,0.5'. For splitting mono to stereo,
it is '\-\^\-mix 1,1' top keep the symmetry.
.TP
\fB\-\^\-filter \fIcoeff
Apply digital filter(s) before pre-amplification (see \fB\-\^\-preamp\fR) with the coefficient
list coeff as
.ce
b_0,...,b_N,a_0,...,a_N
where a_0=1 is mandatory and perhaps helps orientation a bit. Multiple filters are separated
by ':'.
.TP
\fB\-P \fIdbvalue \fB\-\^\-preamp \fIdbvalue
Enable a pre-amplification stage that amplifies the signal with the given value in dB before output.
.TP
\fB\-\^\-offset \fIvalue
Apply a PCM offset (floating point value scaled in [-1:1] in the pre-amplification stage.
Normally, you would do that to correct a known DC offset in a recording.
.TP
\fB\-\^\-clip \fImode
Select clipping mode: 'soft' or 'hard' for forced clipping also for
floating point output, 'implicit' (default) for implied hard clipping during
conversion where necessary.
.TP
\fB\-\^\-dither
Enable dithering for conversions to integer. If you insist.
This is just some un-spectacular TPDF dither. For some people, that is not fancy enough.
Most people cannot be bothered that way or the other.
.TP
.BR \-\^\-test\-format
Check if given format is supported by given driver and device (in command line before
encountering this), silently returning 0 as exit value if it is the case.
.TP
.BR \-\^\-test\-encodings
Print out the short names of encodings supported with the current setup.
.TP
.BR \-\^\-query\-format
If the selected driver and device communicate some default accepted format, print
out a command line fragment for \fBout123\fR setting that format, always in that order:
\-\^\-rate <r> -\^\-channels <c> -\^\-encoding <e>
.TP
.BR "\-o h" ", " \-\^\-headphones
Direct audio output to the headphone connector (some hardware only; AIX, HP, SUN).
.TP
.BR "\-o s" ", " \-\^\-speaker
Direct audio output to the speaker (some hardware only; AIX, HP, SUN).
.TP
.BR "\-o l" ", " \-\^\-lineout
Direct audio output to the line-out connector (some hardware only; AIX, HP, SUN).
.TP
\fB\-b \fIsize\fR, \fB\-\^\-buffer \fIsize
Use an audio output buffer of
.I size
Kbytes. This is useful to bypass short periods of heavy
system activity, which would normally cause the audio output
to be interrupted.
You should specify a buffer size of at least 1024
(i.e. 1 Mb, which equals about 6 seconds of usual audio data) or more;
less than about 300 does not make much sense. The default is 0,
which turns buffering off.
.TP
\fB\-\^\-preload \fIfraction
Wait for the buffer to be filled to
.I fraction
before starting playback (fraction between 0 and 1). You can tune this prebuffering to either get sound faster to your ears or safer uninterrupted web radio.
Default is 0.2 (changed from 1 since version 1.23).
.TP
\fB\-\^\-devbuffer \fIseconds
Set device buffer in seconds; <= 0 means default value. This is the small buffer between the
application and the audio backend, possibly directly related to hardware buffers.
.TP
\fB\-\^\-timelimit \fIsamples
Set playback time limit in PCM samples if set to a value greater than zero.
\fBout123\fR will stop reading from stdin or playing from the generated wave
table after reaching that number of samples.
.TP
\fB\-\^\-seconds \fIseconds
Set time limit in seconds instead.
.TP
\fB\-\^\-source \fIname
Choose the signal source: 'file' (default) for playback of the given file(s) on the command line
or standard input if there are none, or one of the generators 'wave' (see \fB\-\^\-wave\-freq\fR),
'sweep' (see \fB\-\^\-wave\-sweep\fR), 'pink' (see \fB\-\^\-ping\-rows\fR),
geiger (see \fB\-\^\-geiger\-activity\fR), or just 'white' for some white noise.
.TP
\fB\-\^\-wave\-freq \fIfrequencies
Set wave generator frequency or list of those with comma separation for enabling
a generated test signal instead of standard input. Empty values repeat the
previous one.
.TP
\fB\-\^\-wave\-pat \fIpatterns
Set the waveform patterns of the generated waves as comma-separated list.
Choices include sine, square, triangle, sawtooth, gauss, pulse, and shot.
Empty values repeat the previous one.
.TP
\fB\-\^\-wave\-phase \fIphases
Set waveform phase shift(s) as comma-separated list, negative values
inverting the pattern in time and empty value repeating the previous. There is
also \fB\-\^\-wave\-direction\fR overriding the negative bit.
.TP
\fB\-\^\-wave\-direction\fR
Set wave direction explicitly (the sign counts).
.TP
\fB\-\^\-wave\-sweep \fIfrequency
Sweep a generated wave to the given frequency, from
first one specified for \fB\-\^\-wave\-freq\fR, using the
first wave pattern and direction, too.
.TP
\fB\-\^\-sweep\-time \fIseconds
Set frequency sweep duration in seconds if > 0. This defaults
to the configured time limit if set, otherwise one second, as endless
sweeps are not sensible.
.TP
\fB\-\^\-sweep\-count \fIcount
Set timelimit to exactly produce that many (smooth) sweeps
.TP
\fB\-\^\-sweep\-type \fItype
Set sweep type: lin(ear) for linear, qua(d) (default) for quadratic, or exp(onential)
for an exponential change of frequency with time.
.TP
\fB\-\^\-sweep\-hard
Disable post-sweep smoothing for periodicity.
.TP
\fB\-\^\-genbuffer \fIbytes
Set the buffer size (limit) for signal generators,
if > 0 (default), this enforces a periodic
buffer also for non-periodic signals, benefit:
less runtime CPU overhead, as everything is precomputed as enforced periodic signal.
.TP
\fB\-\^\-wave\-limit \fIsamples
This is an alias for \fB\-\^\-genbuffer\fR.
.TP
\fB\-\^\-pink\-rows \fInumber
Activate pink noise source and choose rows for the algorithm (<1 chooses default).
The generator follows code provided by Phil Burk (http://softsynth.com) and uses
the Gardner method.
.TP
\fB\-\^\-geiger\-activity \fInumber
This configures the simulation of a Geiger-Mueller counter as source, with the given
numer as average events per second. Play with it. It's fun!
.TP
.BR \-t ", " \-\^\-test
Test mode. The audio stream is read, but no output occurs.
.TP
.BR \-v ", " \-\^\-verbose
Increase the verbosity level.
.TP
.BR \-q ", " \-\^\-quiet
Quiet. Suppress diagnostic messages.
.TP
\fB\-\^\-aggressive
Tries to get higher priority
.TP
.BR \-T ", " \-\-realtime
Tries to gain realtime priority. This option usually requires root
privileges to have any effect.
.TP
.BR \-? ", " \-\^\-help
Shows short usage instructions.
.TP
.BR \-\^\-longhelp
Shows long usage instructions.
.TP
.BR \-\^\-version
Print the version string.

Hi
* Place Makefile.psp in the directory src/libmpg123.
* Patch readers.c (present in src/libmpg123) using readers.c.patch
* Place Config.h in directory src/
* cd to src/libmpg123 and do "make -f Makefile.psp install"
Tested on mpg123 1.4.x and psptoolchain rev. 2398
