This may require superuser privileges. .TP \fB-e\fR, \fB--extract\fR \fIin.pcap\fR Extract from input pcap file. .TP \fB-p\fR, \fB--port\fR \fIN\fR Set destination port to capture (1\(en65535). By default, the first plausible port number that is seen is captured. .TP \fB-t\fR, \fB--type\fR \fIN\fR Set RTP payload type to capture (0\(en127). By default, the first plausible dynamic payload type (96\(en127) that is seen is captured. .TP \fB-o\fR, \fB--output\fR \fIout.opus\fR Write Ogg Opus output file. .TP \fB-r\fR, \fB--rate\fR \fIN\fR Set original sample rate in Ogg Opus output file (default: 48000). .TP \fB-c\fR, \fB--channels\fR \fIN\fR Set channel count in Ogg Opus output file (default: 2). .SH AUTHORS Ralph Giles <giles@thaumas.net> .SH BUGS The receive mode does not support out-of-order or missing packets, multiple simultaneous RTP streams with the same destination port number and payload type, or normal unicast and multicast receive. .SH SEE ALSO .BR opusdec (1), .BR opusenc (1), .BR opusinfo (1)
