rtcp ¶ ↑

Description¶ ↑

The RTP Control Protocol (RTCP) gathers statistical data about RTP sessions, for example transmitted octet and packet counts, lost packet counts, round-trip delay time and interarrival jitter.

This library parses RTCP data into ruby objects.

Features¶ ↑

Parse RTCP Packets into Ruby Objects
Supports the following RTCP Packet types:
- 200: Sender Report
- 201: Receiver Report
- 202: Source Description
- 203: Goodbye
- 204: Application-Defined (Does not decode application-dependent data)
- 206: Payload-Specific FB message (Does not decode FCI block)
- 207: Extended Report
- 209: Receiver Summary Information

Examples¶ ↑

Parse an `RTCP` Packet¶ ↑

require 'rtcp'

rr = RTCP.decode(rtcp_rr_data)   # => [RTCP::RR Object]
rr.ssrc                          # => 3945864703
rr.length                        # => 8
rr.version                       # => 2
rr.report_blocks                 # => []

Parse a sequence of `RTCP` Packets¶ ↑

require 'rtcp'

msgs = RTCP.decode(rtcp_data)    # => [Array of RTCP::* Objects]

msgs[0].class                    # => RTCP::RR
msgs[0].ssrc                     # => 3945864703

msgs[1].class                    # => RTCP::SDES
msgs[1].chunks                   # => [Array of Hashes]
msgs[1].chunks[0][:ssrc]         # => 3945864703
msgs[1].chunks[0][:type]         # => :cname
msgs[1].chunks[0][:data]         # => "00-09-df-1b-ec-0a"

msgs[2].class                    # => RTCP::RSI
msgs[2].ssrc                     # => 3945864703
msge[2].ntp_timestamp            # => [Time Object]

msgs[3].class                    # => RTCP::APP
msgs[3].name                     # => "PLII"
msgs[3].app_data                 # => [Binary Data -- The application data]

msgs[4].class                    # => RTCP
msgs[4].to_s                     # => [Binary Data -- The whole RTCP packet]
