Code:
--------------------
Squeezelite v1.8.7-1007, Copyright 2012-2015 Adrian Smith, 2015-2017 Ralph
Irving. See -t for license terms
Usage: /usr/local/bin/squeezelite [options]
-s <server>[:<port>] Connect to specified server, otherwise uses
autodiscovery to find server
-o <output device> Specify output device, default "default", - = output to
stdout
-l List output devices
-a <b>:<p>:<f>:<m> Specify ALSA params to open output device, b = buffer
time in ms or size in bytes, p = period count or size in bytes, f sample format
(16|24|24_3|32), m = use mmap (0|1)
-a <f> Specify sample format (16|24|32) of output file when
using -o - to output samples to stdout (interleaved little endian only)
-b <stream>:<output> Specify internal Stream and Output buffer sizes in
Kbytes
-c <codec1>,<codec2> Restrict codecs to those specified, otherwise load all
available codecs; known codecs: flac,pcm,mp3,ogg,aac,wma,alac,dsd (mad,mpg for
specific mp3 codec)
Codecs reported to LMS in order listed, allowing codec
priority refinement.
-C <timeout> Close output device when idle after timeout seconds,
default is to keep it open while player is 'on'
-d <log>=<level> Set logging level, logs:
all|slimproto|stream|decode|output|ir, level: info|debug|sdebug
-G <Rpi GPIO#>:<H/L> Specify the BCM GPIO# to use for Amp Power Relay and if
the output should be Active High or Low
-e <codec1>,<codec2> Explicitly exclude native support of one or more
codecs; known codecs: flac,pcm,mp3,ogg,aac,wma,alac,dsd (mad,mpg for specific
mp3 codec)
-f <logfile> Write debug to logfile
-i [<filename>] Enable lirc remote control support (lirc config file
~/.lircrc used if filename not specified)
-m <mac addr> Set mac address, format: ab:cd:ef:12:34:56
-M <modelname> Set the squeezelite player model name sent to the
server (default: SqueezeLite)
-n <name> Set the player name
-N <filename> Store player name in filename to allow server defined
name changes to be shared between servers (not supported with -n)
-W Read wave and aiff format from header, ignore server
parameters
-p <priority> Set real time priority of output thread (1-99)
-P <filename> Store the process id (PID) in filename
-r <rates>[:<delay>] Sample rates supported, allows output to be off when
squeezelite is started; rates =
<maxrate>|<minrate>-<maxrate>|<rate1>,<rate2>,<rate3>; delay = optional delay
switching rates in ms
-S <Power Script> Absolute path to script to launch on power commands
from LMS
-R -u [params] Resample, params =
<recipe>:<flags>:<attenuation>:<precision>:<passband_end>:<stopband_start>:<phase_response>,
recipe = (v|h|m|l|q)(L|I|M)(s) [E|X], E = exception -
resample only if native rate not supported, X = async - resample to max rate
for device, otherwise to max sync rate
flags = num in hex,
attenuation = attenuation in dB to apply (default is
-1db if not explicitly set),
precision = number of bits precision (NB. HQ = 20. VHQ
= 28),
passband_end = number in percent (0dB pt. bandwidth to
preserve. nyquist = 100%),
stopband_start = number in percent (Aliasing/imaging
control. > passband_end),
phase_response = 0-100 (0 = minimum / 50 = linear /
100 = maximum)
-D [delay] Output device supports DSD over PCM (DoP), delay =
optional delay switching between PCM and DoP in ms
-v Visualiser support
-O <mixer device> Specify mixer device, defaults to 'output device'
-L List volume controls for output device
-U <control> Unmute ALSA control and set to full volume (not
supported with -V)
-V <control> Use ALSA control for volume adjustment, otherwise use
software volume adjustment
-X Use linear volume adjustments instead of in terms of dB
(only for hardware volume control)
-z Daemonize
-Z <rate> Report rate to server in helo as the maximum sample
rate we can support
