Enumerator

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.

enum RTCPCompoundHandler::RTCPPacket::Type

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.
