rplayd - rplay sound server
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
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
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.
-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.
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
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 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
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.
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).
Remove the cache directory and all its contents when rplayd
-s N, --cache-size=N
Maximum size in bytes of the rplay cache, disabled with 0
--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
Enable debug mode.
-f HOST, --forward=HOST
Forward all RPLAY packets to HOST.
--fork Enable backgrounding rplayd at startup. (enabled)
Run with GROUP privs. (audio)
--help Display helpful information.
Use FILE for rplay.helpers (/etc/rplay/rplay.helpers).
-H FILE, --hosts=FILE
Use FILE for rplay.hosts (/etc/rplay/rplay.hosts).
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.
Maximum size in bytes of the memory cache, disable caching with
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)
Disable audio, RPTP file server mode.
Disable host access authentication.
Disable inetd mode. (disabled)
Disable backgrounding rplayd at startup. (enabled)
Read rplayd options from FILE.
Use PORT as the RPLAY/UDP port. (5555) (--other-rplay-port may
also be available)
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).
Run with USER privs. (nobody)
Print the rplay version and exit.
