Detailed Description

Constructor & Destructor Documentation

jrtplib::RTCPScheduler::RTCPScheduler	(	RTPSources &	sources,
		RTPRandom &	rtprand
	)

Creates an instance which will use the source table RTPSources to determine when RTCP compound packets should be scheduled. Note that for correct operation the sources instance should have information about the own SSRC (added by RTPSources::CreateOwnSSRC). You must also supply a random number generator rtprand which will be used for adding randomness to the RTCP intervals.

RTPTime jrtplib::RTCPScheduler::CalculateDeterministicInterval

(

bool

sender = false

)

Calculates the deterministic interval at this time. This is used - in combination with a certain multiplier - to time out members, senders etc.

RTPTime jrtplib::RTCPScheduler::GetTransmissionDelay

(

)

Returns the delay after which an RTCP compound will possibly have to be sent. The IsTime member function should be called afterwards to make sure that it actually is time to send an RTCP compound packet.

bool jrtplib::RTCPScheduler::IsTime

(

)

This function returns true if it's time to send an RTCP compound packet and false otherwise. If the function returns true, it will also have calculated the next time at which a packet should be sent, so if it is called again right away, it will return false.
