NAME
rplayd - rplay sound server
SYNOPSIS
rplayd [options]
DESCRIPTION
rplayd is the sound server for the rplay audio system. The server listens for requests to
play, pause, continue, and stop sounds using both the RPLAY and RPTP protocols. Normally
RPLAY requests are received on port 5555/udp and RPTP on 5556/tcp. (Older ports 55555/udp
and 55556/tcp are also supported) Access to the server is restricted using the
rplay.hosts file.
rplayd can be started during the system boot process, via inetd, or by individual users.
root access may be required depending on audio device permissions.
In most causes rplayd will play sounds that are available on the local disk. However,
rplayd can be sent sounds via the network and rplayd can also contact other rplayds to
share sound files. The index of all the local sound files is stored in rplay.conf and
remote rplayds are specified in rplay.servers. Sounds received from other rplayds will be
stored in a cache directory normally located in /tmp/.rplay-cache. Cache entries are
expired on an LRU basis.
Many sound file formats are supported by rplayd. These include:
AU AIFF WAV VOC UB UL
G.721 4-bit, G.723 3-bit, G.723 5-bit
GSM
Other formats can be played using external helper applications which convert unknown file
formats to CD quality data which can then be played by rplayd. See rplay.helpers(5)
Several sounds can be played at once and sounds can be played at any sample rate. rplayd
can be configured to output many different formats using the various --audio options.
On some systems, namely Solaris and Linux, rplayd can read sounds directly from CDROM
using CDDA. The special sound name cdrom: will play the entire CDROM. cdrom:3-5 will
play tracks 3 through 5.
OPTIONS
-A DEVICE, --audio-device=DEVICE
Use DEVICE for the audio device (/dev/dsp).
-B N, --audio-bits=N
Audio device bits per sample, 8 or 16.
--audio-channels=N
Number of audio channels to use, 1 == mono, 2 == stereo.
-c N, --audio-close=N
Close /dev/dsp after N idle seconds, disabled with 0 (5).
-F N, --audio_flush=N
Flush /dev/dsp after N idle seconds, disabled with 0 (-1). N = -1 : flush when
spool is empty. N = -2 : flush after each audio write. (not recommended) N should
be <= to the audio close timeout.
--audio-format=FORMAT
Tell rplayd to write audio data using FORMAT, where FORMAT can be ulaw, linear-8,
ulinear-8, linear-16, or ulinear-16. (linear = signed, ulinear = unsigned)
--audio-fragsize=N
Audio fragment size (0). The default size is zero which lets the audio driver pick
the "best" size. The size specified must be a power of 2 greater than 16.
Example: 256, 1024, 4096.
--audio-info=INFO, --info=INFO, -i INFO
Specify complete audio device information with one option. INFO is of the form:
format,sample-rate,bits,channels Examples: `ulaw,8000,8,1' and
`linear-16,44100,16,2' Also provided are:
--audio-info-ulaw, --info-ulaw -> ulaw,8000,8,1
--audio-match
Attempt to match the sample rate of the audio device with the sample rate of the
current sound when no other sounds are playing. If the match fails,
--audio-sample-rate is used. This option overrides --audio-bufsize.
--audio-port=PORT[,PORT...]
Output audio to the specified audio port(s). Valid ports are `speaker',
`headphone', and `lineout'. Multiple ports can be specified using
`speaker,headphone,lineout'
-r N, --audio-rate=N
Write the audio buffer N times per second (0).
-R N, --audio-sample-rate=N
Sample rate of the audio device.
--auth Enable host access authentication.
-D DIR, --cache-directory=DIR
Use DIR for rplay.cache (/tmp/.rplay-cache).
--cache-remove
Remove the cache directory and all its contents when rplayd exists.
-s N, --cache-size=N
Maximum size in bytes of the rplay cache, disabled with 0 (8388608).
--cdrom0=DEVICE, --cdrom1=DEVICE, --cdrom2=DEVICE, --cdrom3=DEVICE
Specify the cdrom[0-3] to DEVICE mapping. For Solaris 2.x the default mapping is
cdrom[0-3] -> /vol/dev/aliases/cdrom[0-3]. Linux uses cdrom[0-3] ->
/dev/cdrom[0-3].
-C FILE, --conf=FILE
Use FILE for rplay.conf (/etc/rplay/rplay.conf).
-T N, --connection-timeout=N
Close idle RPTP connections after N seconds, disabled with 0 (300).
-d, --debug
Enable debug mode.
-f HOST, --forward=HOST
Forward all RPLAY packets to HOST.
--fork Enable backgrounding rplayd at startup. (enabled)
--group=GROUP
Run with GROUP privs. (audio)
--help Display helpful information.
--helpers=FILE
Use FILE for rplay.helpers (/etc/rplay/rplay.helpers).
-H FILE, --hosts=FILE
Use FILE for rplay.hosts (/etc/rplay/rplay.hosts).
--inetd
Enable inetd mode. (disabled)
-L FILE, --log-file=FILE
Use file for rplay.log (/tmp/rplay.log).
-l N, --log-level=N
Use logging level N where 0 <= n <= 4.
--memory-cache-size=N
Maximum size in bytes of the memory cache, disable caching with 0 (4194304).
--memory-cache-sound-size=N
Maximum size in bytes of a sound that can be cached in memory. A value of 0 means
to try and cache all sounds. (2097152)
-N, --no-audio
Disable audio, RPTP file server mode.
--no-auth
Disable host access authentication.
-n, --no-inetd
Disable inetd mode. (disabled)
--no-fork
Disable backgrounding rplayd at startup. (enabled)
--options-file=FILE
Read rplayd options from FILE.
--port=PORT, --rplay-port=PORT
Use PORT as the RPLAY/UDP port. (5555) (--other-rplay-port may also be available)
--rptp-port=PORT
Use PORT as the RPTP/TCP port. (5556) (--other-rptp-port may also be available)
-S FILE, --servers=FILE
Use FILE for rplay.servers (/etc/rplay/rplay.servers).
-t N, --timeout=N
Exit after N idle seconds, disabled with 0 (0).
--user=USER
Run with USER privs. (nobody)
-v, --version
Print the rplay version and exit.
