+.B rtp_always_request yes\fR|\fBno
+If
+.B yes
+then
+.BR disorder-playrtp (1)
+will always request a dedicated RTP stream,
+rather than contacting the server to discover
+a broadcast or multicast address.
+(This behaviour can be overridden by
+setting a suitable address on the command-line.)
+The default is
+.BR no .

+This option is experimental,
+and may change or be removed in a future release.
+.TP
+.B rtp_maxbuffer \fIFRAMES\fR
+Set
+.BR disorder-playrtp (1)'s
+buffer size to the given number of
+.IR FRAMES .
+If this is zero, then
+.B disorder-playrtp
+will select a default buffer size.
+(This setting can be overridden by passing
+a suitable command-line option.)
+The default value is
+.BR 0 .

+This option is experimental,

+.B rtp_minbuffer \fIFRAMES\fR
+Set
+.BR disorder-playrtp (1)'s
+buffer low-water-mark to the given number of
+.IR FRAMES .
+If this is zero, then
+.B disorder-playrtp

+.B rtp_mode \fIMODE\fR
+The network transmission mode for the \fBrtp\fR backend.
+Possible values are:
+.RS
+.TP
+.B unicast
+Unicast transmission to the address given by \fBbroadcast\fR.
+.TP
+.B broadcast
+Broadcast transmission to the address given by \fBbroadcast\fR.
+.TP
+.B multicast
+Multicast transmission to the address given by \fBbroadcast\fR.
+.TP
+.B request
+Unicast transmission to addresses requested by clients.
+.TP
+.B auto
+Choose one of the above based on the destination address.
+This is the default, for backwards compatibility reasons.

+.B rtp_rcvbuf \fISIZE\fR
+Set
+.BR disorder-playrtp (1)'s
+socket receive buffer to at least
+.IB SIZE .
+(This setting can be overridden by passing

+.B rtp_request_address \fR[\fIFAMILY\fR] \fR[\fIHOST\fR] \fISERVICE\fR
+If
+.BR disorder-playrtp (1)
+is to request a unicast RTP stream,
+then it should establish its receiving socket
+to listen on the given address.
+The
+.I FAMILY
+and
+.I HOST
+may be omitted, in which case
+.B disorder-playrtp
+uses heuristics to determine suitable values.
+The
+.I PORT
+may be omitted, in which case
+.B disorder-playrtp
+uses a kernel-allocated port.
+(This setting can be overridden by passing
+a suitable address on the command line.)
+The default is
+.RB ` "\- 0" ',
+which uses a heuristically-chosen address and a kernel-allocated port.
