RTPDUMP(1) General Commands Manual RTPDUMP(1) NAME rtpdump -- parse and print RTP packets SYNOPSIS rtpdump [-h] [-F format] [-f infile] [-o outfile] [-t minutes] [-x bytes] [address]/port DESCRIPTION rtpdump reads RTP and RTCP packets on the given address/port, or from stan- dard input by default, and dumps a processed version to standard output. The output is suitable as input for rtpplay(1) and rtpsend(1). The IPv4 address can be specified in dotted decimal notation or as a hostname and defaults to 127.0.0.1. The port number must be given as a decimal numbers between 1 and 65535. The options are as follows: -F format Write the output in the given format, which is one of the follow- ing: dump, header, payload, ascii, hex, rtcp, short. The dump format is a binary format suitable as input for rtp- play(1). The generated output file should have a .rtp filename ex- tension. The file starts with #!rtpplay1.0 address/port\n The version number indicates the file format version, not the ver- sion of RTP tools used to generate the file. The current file for- mat version is 1.0. This is followed by one RD_hdr_t header and one RD_packet_t structure for each received packet. All fields are in network byte order. The RTP and RTCP packets are recorded as- is. The structures are as follows: typedef struct { struct timeval start; /* start of recording (GMT) */ uint32_t source; /* network source (multicast) */ uint16_t port; /* UDP port */ } RD_hdr_t; typedef struct { uint16_t length; /* length of original packet, including header */ uint16_t plen; /* actual header+payload length for RTP, 0 for RTCP */ uint32_t offset; /* ms since the start of recording */ } RD_packet_t; The header format is like dump, but does not save the audio/video payload. The payload format only saves the audio/video payload. The ascii format, which is the default, saves text parsed packets, suitable for rtpsend(1). See below for an example. The hex format is like ascii, but with a hex dump of the payload. The rtcp format is like ascii, but only saves RTCP packets. The short format dumps RTP or VAT data in lines such as [-]time timestamp [seq] where `-' indicates a set marker bit, time is the arrival time, timestamp is the RTP timestamp, and seq is the RTP sequence number (only used for RTP packets). -f infile Read packets from infile instead of from the network or from stan- dard input. The file must have been recorded using the dump for- mat. -h Print a short usage summary and exit. -o outfile Dump to outfile instead of to standard output. -t minutes Only listen for the first minutes. -x bytes Process only the first number of bytes of the payload. This is only applicable for the dump and hex formats.
