ConstructL()

void ConstructL ( ) [private]

EstimateBandWidths(TUint32)

void EstimateBandWidths ( TUint32 aCurrentTime ) [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)

void IncCumNumOctetsSent ( TUint32 aInc ) [private, inline]

Parameters

TUint32 aInc

NewL(const TRtpPayloadType, const TRtpId, const TRtpId, const TRtpSSRC, MRtcpObserver *, const TUint32 *)

const TRtpId aSessionID,
const TRtpId aTranStreamID,
const TRtpSSRC aSSRC,
MRtcpObserver * aObserver,
const TUint32 * aProfileRTPTimeRates
) [static]

Parameters

const TRtpPayloadType aPayloadType
const TRtpId aSessionID
const TRtpId aTranStreamID
