NAME

rtcppacket - RTCP compound packets manipulation.

SYNOPSIS

Classes

class RTCPCompoundHandler
low level structs and RTCP packet parsing and building methods.
class RTCPReceiverInfo
Report block information of SR/RR RTCP reports.
class RTCPSenderInfo
Sender block information of SR RTCP reports.

Enumerations

enum SDESItemType { SDESItemTypeEND = 0, SDESItemTypeCNAME , SDESItemTypeNAME , SDESItemTypeEMAIL , SDESItemTypePHONE , SDESItemTypeLOC , SDESItemTypeTOOL , SDESItemTypeNOTE , SDESItemTypePRIV , SDESItemTypeH323CADDR , SDESItemTypeLast = SDESItemTypeH323CADDR }
SDES items that may be carried in a Source DEScription RTCP packet.

Functions

timeval NTP2Timeval (uint32 msw, uint32 lsw)
Convert a NTP timestamp, expressed as two 32-bit long words, into a timeval value.
uint32 timevalIntervalTo65536 (timeval &t)
Convert a time interval, expressed as a timeval, into a 32-bit time interval expressed in units of 1/65536 seconds.

Detailed Description

Enumeration Type Documentation

enum SDESItemType

SDES items that may be carried in a Source DEScription RTCP packet. CNAME is mandatory in each RTCP compound packet (except when split for partial encryption), the others are optional and have different sending frequencies, though with recommended default values.

Enumerator
SDESItemTypeEND

END of SDES item list.

SDESItemTypeCNAME

Canonical end-point identifier.

SDESItemTypeNAME

Personal NAME of the user.

SDESItemTypeEMAIL

EMAIL address of the user.

SDESItemTypePHONE

Phone number of the user.

SDESItemTypeLOC

Location where the user is.

SDESItemTypeTOOL

Application or tool.

SDESItemTypeNOTE

Comment usually reporting state.

SDESItemTypePRIV

Private extension.

SDESItemTypeH323CADDR

H323 callable address.

SDESItemTypeLast

Last defined code.

Function Documentation

timeval NTP2Timeval (uint32 msw, uint32 lsw)

Convert a NTP timestamp, expressed as two 32-bit long words, into a timeval value.

Parameters

msw Integer part of NTP timestamp.
lsw
Fractional part of NTP timestamp.

Returns

timeval value corresponding to the given NTP timestamp.

uint32 timevalIntervalTo65536 (timeval & t)

Convert a time interval, expressed as a timeval, into a 32-bit time interval expressed in units of 1/65536 seconds.

Parameters

t Timeval interval.

Returns

32-bit value corresponding to the given timeval interval.
