SRTP

[SAGET Jean-Claude]

Hello Ross,

I'm working at Thales with Yahia. I am writing to inform you that we have encountered two problems regarding SRTP.

First, in method OnDemandServerMediaSubsession::sdpLines(int addressFamily) if the following test if (rtpSink != NULL && rtpSink->srtpROC() != fSRTP_ROC) is true then a temporary sink is created. The problem is that the temporary sink changes the sink in attribute fRTPSink of PresentationTimeSubsessionNormalizer because of the line ssNormalizer->setRTPSink(newSink) in ProxyServerMediaSubsession::createNewRTPSink(...). Next in PresentationTimeSessionNormalizer::normalizePresentationTime(PresentationTimeSubsessionNormalizer* ssNormalizer,...) the temporary and deleted sink is modified at line rtpSink->enableRTCPReports() = True;.
In fact we have a subclass of ProxyServerMediaSubsession  with a similar createNewRTPSink method.

The second is minor, there is delete fSDPLines instead of delete[] in OnDemandServerMediaSubsession::sdpLines(int addressFamily).

Regards
Jean-Claude Saget
