Detailed Description

Dejitter buffer for incoming data packets.

A dejitter buffer that can be inserted in the receive data path to absorb variations in packet arrival time. Incoming packets are stored and forwarded at fixed intervals.

Constructor & Destructor Documentation

RTPDejitter()

RTPDejitter	(	RTPReceiver *	receiver,
		unsigned int	mindelay,
		unsigned int	maxdelay,
		DebugEnabler *	dbg = 0,
		const char *	traceId = 0 )

Constructor of a new jitter attenuator

Parameters

receiver	RTP receiver which gets the delayed packets
mindelay	Minimum length of the dejitter buffer in microseconds
maxdelay	Maximum length of the dejitter buffer in microseconds
dbg	Dejitter DebugEnabler
traceId	Dejitter trace ID

References RTPDebug::dbg(), and GenObject::traceId().

~RTPDejitter()

virtual ~RTPDejitter ( )

virtual

Destructor - drops the packets and shows statistics

Member Function Documentation

clear()

void clear

(

)

Clear the delayed packets queue and all variables

rtpRecv()

virtual bool rtpRecv ( bool marker, int payload, unsigned int timestamp, const void * data, int len )

virtual

Process and store one RTP data packet

Parameters

marker	True if the marker bit is set in data packet
payload	Payload number
timestamp	Sampling instant of the packet data
data	Pointer to data block to process
len	Length of the data block in bytes

Returns

True if the data packet was queued

timerTick()

virtual void timerTick ( const Time & when )

protectedvirtual

Method called periodically to keep the data flowing

Parameters

when	Time to use as base in all computing

Implements RTPProcessor.
