[Ccrtp-devel] Re: problem with End2EndDelay and SR Packets

[Supriya Kher]

 

 

Further on this , the wireshark capture shows both RR and SR packets bieng transmitted between
source and destination , the source is receiveing the SR packets from the destination, but no OnGotSR method is invoked.

I have a confusion here ,
is the OnGotSR method invoked when --
when sender has some data to send to destination Whereby it sends the data and then generates a SR and this invokes the OnGotSR ?
Or
Is the OnGotSR invoked when SR is received from the other party ?

pls clarify.

Hi ,

 

Am using ccrtp library to measure the end to end delay observed in a

VoIP Call.

 

I did see some thread on the delay and jitter buffer calculations..but

they seemed to have not recvd any reply.

 

MY questions are -

 

1) I am using ccrtp to measure the end to end delay

 with both the source and destination being in the same LAN.

 The API QueueRTCPManager::getEnd2EndDelay () always seems

 to give me a delay of 0.

 

2) Also , when I run rtcplisten demo application , and dial a call from

A --> B  with rtplisten demo running on A and B as well , I see only RTCP RR packets being recvd. the OnGotRR() method is being invoked.

However no RTCP SR packets are seen, the OnGotSR method is not invoked thereby.

What could be the reason ?

 

 

thanks
