.PP
If an address and a port are specified then the RTP stream is assumed to be
multicast to that group address and port.
+.PP
+Alternatively, the
+.I ADDRESS
+can start with a
+.RB ` \- ',
+in which case
+.B disorder-playrtp
+will request a dedicated unicast stream from the server. The
+.RB ` \- '
+may be followed by an optional port, or address/port pair, which will be the
+local address/port to bind to and announce to the server.
.SH OPTIONS

.B \-\-api\fR, -\fB-A\fR \fIAPI\fR
control.
.TP
.B \-\-config \fIPATH\fR, \fB\-C \fIPATH
-Set the configuration file.
+Set the system configuration file.
The default is
+given by the
+.B DISORDER_CONFIG
+environment variable, defaulting to
.IR pkgconfdir/config .
.TP
+.B \-\-user-config \fIPATH\fR, \fB\-u \fIPATH
+Set the user configuration file.
+THe default is given by the
+.B DISORDER_USERCONFIG
+environment variable, defaulting to
+.IR $HOME/.disorder/passwd .
+.TP
.B \-\-socket \fIPATH\fR, \fB\-s \fIPATH
Set the control socket.
Normally this would not be used manually.
.B \-\-min \fIFRAMES\fR, \fB\-m \fIFRAMES\fR
Specifies the buffer low watermark in frames.
This also acts as the target buffer occupancy.
+The default is taken from the
+.B rtp_minbuffer
+configuration parameter.
.TP
.B \-\-max \fIFRAMES\fR, \fB\-x \fIFRAMES\fR
Specifies the maximum buffer size in frames.
If there are this many frames in the buffer then reading from the
network socket will be suspended.
The default is twice the \fB\-\-min\fR value.
+The default is taken from the
+.B rtp_maxbuffer
+configuration parameter.
.TP
.B \-\-rcvbuf \fIBYTES\fR, \fB\-R \fIBYTES\fR
Specifies socket receive buffer size.
The default is not to change the buffer size, i.e. you get whatever the
local operating system chooses.
The buffer size will not be reduced below the operating system's default.
+The default is taken from the
+.B rtp_rcvbuf
+configuration parameter.
.TP
.B \-\-monitor\fR, \fB\-M
Periodically report how close to the buffer low watermark the buffer is.
