       mpg123 -	play audio MPEG	1.0/2.0/2.5 stream (layers 1, 2	and 3)

       mpg123 [	options	] file-or-URL...

       mpg123  reads  one  or more files (or standard input if ``-'' is	speci-
       fied) or	URLs and plays them on the audio device	(default)  or  outputs
       them to stdout.	file/URL is assumed to be an MPEG audio	bit stream.

       The following operands are supported:

       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 stan-
	       dard input.  Furthermore, any name starting with	``http://'' is
	       recognized as URL (see next section).

       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 op-
       tions  can  be absent from your installation when disabled in the build

       -k num, --skip num
	      Skip first num frames.  By default the decoding  starts  at  the
	      first frame.

       -n num, --frames	num
	      Decode  only  num	frames.	 By default the	complete stream	is de-

	      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.

       -y, --no-resync
	      Do NOT try to resync and continue	decoding if an error occurs in
	      the  input  file.	 Normally,  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 re-
	      named from --resync.  The	old name still works, but is  not  ad-
	      vertised or recommened to	use (subject to	removal	in future).

       -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 ...

       --resync-limit bytes
	      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  ham-
	      mer.   Note:  Only  since	 version  1.14 this also increases the
	      amount of	junk skipped on	beginning.

       -p URL |	none, --proxy URL | none
	      The specified proxy will be used for HTTP	requests.   It	should
	      be specified as full URL (``http://host.domain:port/''), but the
	      ``http://'' prefix, the port number and the trailing  slash  are
	      optional (the default port is 80).  Specifying none means	not to
	      use any proxy, and to retrieve files directly from  the  respec-
	      tive servers.  See also the ``HTTP SUPPORT'' section.

       -u auth,	--auth auth
	      HTTP  authentication  to use when	recieving files	via HTTP.  The
	      format used is user:password.

	      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.

	      Do not accept ICY	meta data.

       --streamdump filename
	      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?

       --icy-interval bytes
	      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.

	      Disable the default micro-buffering of non-seekable streams that
	      gives the	parser a safer footing.

       -@ file,	--list file
	      Read filenames and/or URLs of MPEG audio streams from the	speci-
	      fied file	in addition to the ones	specified on the command  line
	      (if any).	 Note that 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 -@ option can be used (if  more  than
	      one is specified,	only the last one will be recognized).

       -l n, --listentry n
	      Of  the playlist,	play specified entry only.  n is the number of
	      entry starting at	1. A value of  0  is  the  default  and	 means
	      playling	the whole list,	 a negative value means	showing	of the
	      list of titles with their	numbers...

	      Enable playlist continuation mode. This changes  frame  skipping
	      to apply only to the first track and also	continues to play fol-
	      lowing tracks in playlist	after the selected one.	Also, the  op-
	      tion  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 posi-
	      tions consistent.

       --loop times
	      for looping track(s) a certain number of times, <	0 means	 infi-
	      nite loop	(not with --random!).

	      For  remote  control  mode: Keep loaded file open	after reaching

       --timeout seconds
	      Timeout in (integer) seconds before declaring a stream dead  (if
	      <= 0, wait forever).

       -z, --shuffle
	      Shuffle play.  Randomly shuffles the order of files specified on
	      the command line,	or in the list file.

       -Z, --random
	      Continuous random	play.  Keeps picking a random  file  from  the
	      command  line or the play	list.  Unlike shuffle play above, ran-
	      dom play never ends, and plays individual	songs more than	once.

       -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	 oper-
	      ating on playback.

       --index-size size
	      Set the number of	entries	in the seek frame index	table.

       --preframes num
	      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  en-
	      forced  (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).

       -o module, --output module
	      Select  audio  output  module. You can provide a comma-separated
	      list to use the first one	that works.  Also see -a.

	      List the available modules.

       -a dev, --audiodevice dev
	      Specify the audio	device to use.	The default  as	 well  as  the
	      possible	values	depend on the active output. For the JACK out-
	      put, a comma-separated list of ports to  connect	to  (for  each
	      channel) can be specified.

       -s, --stdout
	      The  decoded  audio  samples are written to standard output, in-
	      stead of playing them through the	 audio	device.	  This	option
	      must  be used if your audio hardware is not supported by mpg123.
	      The output format	per default is raw (headerless)	linear PCM au-
	      dio data,	16 bit,	stereo,	host byte order	(you can force mono or

       -O file,	--outfile
	      Write raw	output into a  file  (instead  of  simply  redirecting
	      standard output to a file	with the shell).

       -w file,	--wav
	      Write  output as WAV file. This will cause the MPEG stream to be
	      decoded and saved	as file	file , or standard output if - is used
	      as  file	name.  You  can	also use --au and --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.

       --au file
	      Does  not	 play the MPEG file but	writes it to 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.

       --cdr file
	      Does not play the	MPEG file but writes it	to file	as a CDR file.
	      If - is used as the filename, the	CDR file is written to stdout.

	      Forces reopen of the audiodevice after ever song

       --cpu decoder-type
	      Selects  a certain decoder (optimized for	specific CPU), for ex-
	      ample i586 or MMX.  The list of available	decoders can vary; de-
	      pending  on  the build and what your CPU supports.  This options
	      is only availabe when the	build actually includes	several	 opti-
	      mized decoders.

	      Tests your CPU and prints	a list of possible choices for --cpu.

	      Lists  all  available  decoder choices, regardless of support by
	      your CPU.

       -g gain,	--gain gain
	      [DEPRECATED] Set audio  hardware	output	gain  (default:	 don't
	      change).	The unit of the	gain value is hardware and output mod-
	      ule dependent.  (This parameter is only provided	for  backwards
	      compatibility and	may be removed in the future without prior no-
	      tice. Use	the audio player for playing and a mixer app for  mix-
	      ing, UNIX	style!)

       -f factor, --scale factor
	      Change scale factor (default: 32768).

       --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.

       --rva-album, --rva-audiophile
	      Enable  RVA (relative volume adjustment) using the values	stored
	      for ReplayGain audiophile	mode / album mode with usually the ef-
	      fect  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.

       -0, --single0; -1, --single1
	      Decode only channel 0 (left) or channel 1	(right), respectively.
	      These options are	available for stereo MPEG streams only.

       -m, --mono, --mix, --singlemix
	      Mix  both	 channels  /  decode mono. It takes less CPU time than
	      full stereo decoding.

	      Force stereo output

       -r rate,	--rate rate
	      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.

       --resample method
	      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  re-
	      ally  low	 on  CPU  time,	 choose	NtoM, as the resampler usually
	      needs more time than the MPEG decoder itself.  The  mpg123  pro-
	      gram  is	smart  enough to combine the 2to1 or 4to1 downsampling
	      modes with the postprocessing for	extreme	downsampling.

       -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.

       --pitch value
	      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.

       --8bit Forces 8bit output

	      Forces f32 encoding

       -e enc, --encoding enc
	      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 num-
	      bers of bits (s24, u24, s16, u16,	s8, u8)	and also special vari-
	      ants  like  ulaw	and  alaw  8-bit.   See	the output of mpg123's
	      longhelp for actually available encodings.

       -d n, --doublespeed n
	      Only play	every n'th frame.  This	will cause the MPEG stream  to
	      be played	n times	faster,	which can be used for special effects.
	      Can also be combined with	the --halfspeed	option to play	3  out
	      of  4  frames  etc.  Don't expect	great sound quality when using
	      this option.

       -h n, --halfspeed n
	      Play each	frame n	times.	This will cause	the MPEG stream	to  be
	      played  at  1/n'th speed (n times	slower), which can be used for
	      special effects. Can also	be combined with the --doublespeed op-
	      tion to double every third frame or things like that.  Don't ex-
	      pect great sound quality when using this option.

       -E file,	--equalizer
	      Enables equalization, taken from file.  The file needs  to  con-
	      tain  32 lines of	data, additional comment lines may be prefixed
	      with #.  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 high-
	      est frequency band.  Note	that you can control the equalizer in-
	      teractively with the generic control interface.

	      Enable  code  that  cuts	(junk) samples at beginning and	end of
	      tracks, enabling gapless transitions between MPEG	files when en-
	      coder  padding  and  codec delays	would prevent it.  This	is en-
	      abled per	default	beginning with mpg123 version 1.0.0 .

	      Disable the gapless code.	That gives you MP3 decodings that  in-
	      clude encoder delay and padding plus mpg123's decoder delay.

	      Do  not  parse  the  Xing/Lame/VBR/Info frame, decode it instead
	      just like	a stupid old MP3 hardware player.  This	 implies  dis-
	      abling  of  gapless  playback as the necessary information is in
	      said metadata frame.

       -D n, --delay n
	      Insert a delay of	n seconds before each track.

       -o h, --headphones
	      Direct audio output to the headphone  connector  (some  hardware
	      only; AIX, HP, SUN).

       -o s, --speaker
	      Direct  audio  output  to	the speaker  (some hardware only; AIX,
	      HP, SUN).

       -o l, --lineout
	      Direct audio output to the  line-out  connector  (some  hardware
	      only; AIX, HP, SUN).

       -b size,	--buffer size
	      Use  an  audio  output buffer of size Kbytes.  This is useful to
	      bypass short periods of heavy system activity, which would  nor-
	      mally  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

       --preload fraction
	      Wait  for	 the  buffer  to be filled to fraction before starting
	      playback (fraction between 0 and 1).  You	 can  tune  this  pre-
	      buffering	to either get faster sound to your ears	or safer unin-
	      terrupted	web radio.  Default is 0.2 (wait for 20	% of buffer to
	      be full, changed from 1 in version 1.23).

       --devbuffer seconds
	      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.

	      Keep  buffer  over track boundaries -- meaning, do not empty the
	      buffer between tracks for	possibly some added smoothness.

       -t, --test
	      Test mode.  The audio stream is decoded, but no output occurs.

       -c, --check
	      Check for	filter range violations	(clipping),  and  report  them
	      for each frame if	any occur.

       -v, --verbose
	      Increase	the  verbosity level.  For example, displays the frame
	      numbers during decoding.

       -q, --quiet
	      Quiet.  Suppress diagnostic messages.

       -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.

	      Disable terminal control even if terminal	is detected.

	      In  an xterm, rxvt, screen, iris-ansi (compatible, TERM environ-
	      ment variable is examined), change the  window's	title  to  the
	      name of song currently playing.

       --name name
	      Set  the name of this instance, possibly used in various places.
	      This sets	the client name	for JACK output.

	      Display ID3 tag info always in long format  with	one  line  per
	      item (artist, title, ...)

       --utf8 Regardless  of  environment, print metadata in UTF-8 (otherwise,
	      when not using UTF-8 locale, you'll get ASCII stripdown).

       -R, --remote
	      Activate generic control interface.  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.

	      Print responses for generic control mode to standard error,  not
	      standard out.  This is automatically triggered when using	-s N.

       --fifo path
	      Create  a	 fifo  / named pipe on the given path and use that for
	      reading commands instead of standard input.

	      Tries to get higher priority

       -T, --realtime
	      Tries to gain realtime priority.	This option  usually  requires
	      root privileges to have any effect.

       -?, --help

       In  addition to reading MPEG audio streams from ordinary	files and from
       the standard input, mpg123 supports retrieval of	MPEG  audio  files  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://''.  When	a file with that prefix	is encountered,	mpg123
       attempts	to open	an HTTP	connection to the server in order to  retrieve
       that file to decode and play it.

       It  is  often useful to retrieve	files through a	WWW cache or so-called
       proxy.  To accomplish this, mpg123 examines the environment  for	 vari-
       ables  named  MP3_HTTP_PROXY, http_proxy	and HTTP_PROXY,	in this	order.
       The value of the	first one that is set will be used as proxy specifica-
       tion.   To  override  this, you can use the -p command line option (see
       the ``OPTIONS'' section).  Specifying -p	none will  enforce  contacting
       the  server  directly without using any proxy, even if one of the above
       environment variables is	set.

       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 exam-
       ple, 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  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	wget(1)) and then play
       them from there.

       If authentication is needed to access the file it can be	specified with
       the -u user:pass.

       When  in	 terminal  control  mode, you can quit via pressing the	q key,
       while any time you can abort mpg123 by pressing Ctrl-C. If not in  ter-
       minal  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).

       Note  that  the	result of quitting 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.

       In verbose mode,	mpg123 updates a line with various information center-
       ing  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:

       >      single-character	playback  state	 (``>''	for playing, ``='' for
	      pausing/looping, ``_'' for stopped)

	      current frame offset and number of remaining  frames  after  the

       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 -m option to decode	mono only, which reduces the CPU  load
       somewhat	for layer-3 streams.  See also the -2 and -4 options.

       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	proba-
       bly  you	can configure mpg123 to	produce	a format suitable for your au-
       dio device (see above about encodings and sampling rates).

       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	option
       to use a	buffer of reasonable size (at least 1000 Kbytes).

       Up to version 1.25.x, mpg123 always returned exit code 0	also for  com-
       plete  junk  on	the  input side. Fatal errors were only	considered for
       output. With version 1.26.0, this changed to  the  behaviour  described

       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  re-
       ally  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.

       An error	in audio output	results	in the process ending with a  non-zero
       exit  code  immediately,	 regardless of how much	data has been success-
       fully played before. The	forgiveness is only on the input side.

       Mostly MPEG-1 layer 2 and 3 are tested in real life.  Please report any
       issues and provide test files to	help fixing them.

       No CRC error checking is	performed.

       Some  platforms lack audio hardware support; you	may be able to use the
       -s switch to feed the decoded data to a program that  can  play	it  on
       your audio device.
