ConstructL()

voidConstructL()[private]

EstimateBandWidths(TUint32)

voidEstimateBandWidths(TUint32aCurrentTime)[private]
Makes an estimate of the Tx and Rx bandwidths. NOTE: This is just a simple estimate, which assumes the following:

  • this is an end-to-end session

  • the sessions and streams are set up before traffic starts

  • the payload bitrate is constant The result of this estimation should not be used in any other contexts.

Parameters

TUint32 aCurrentTime

GetStreamStat(TRtpPeerStat &)

TInt GetStreamStat(TRtpPeerStat &aStat)[virtual]

Parameters

TRtpPeerStat & aStat

IncCumNumOctetsSent(TUint32)

voidIncCumNumOctetsSent(TUint32aInc)[private, inline]

Parameters

TUint32 aInc

)[static]

Parameters

const TRtpPayloadType aPayloadType
