Member Functions Documentation

AuthenticationTag()

TPtrC8 AuthenticationTag()[virtual]

virtual function for getting the authentication tag, implemented in CSRTPPacketSRTP/CSRTPPacketSRTCP

ConstructL()

voidConstructL()[protected]

CopyHeaderAndPayloadL(TUint, TUint8 *)

HBufC8 *CopyHeaderAndPayloadL(TUintaPacketSize,
TUint8 *aPayloadPtr
)
Create a new packet by allocating given size and by copying header and given payload. This can be any packet: RTP/SRTP/RTCP/SRTCP
leave
KErrNone if success, system-wide error code otherwise

Parameters

TUint aPacketSizenew packet size.
TUint8 * aPayloadPtrpointer to the payload to be copied.

CountSenderPacketIndex()

voidCountSenderPacketIndex()[virtual]

virtual function for counting the sender-side packet index implemented in CSRTPPacketRTP

CreateDecryptedPacketL(TUint8 *)

HBufC8 *CreateDecryptedPacketL(TUint8 *aDecryptedPayloadPtr)[virtual]

virtual function for creating decrypted packet, implemented in CSRTPPacketSRTP/CSRTPPacketSRTCP,

Parameters

TUint8 * aDecryptedPayloadPtr

CreateEncryptedPacketL(TUint8 *)

HBufC8 *CreateEncryptedPacketL(TUint8 *aEncryptedPayloadPtr)[virtual]

virtual function for creating encrypted packet, implemented in CSRTPPacketRTP/CSRTPPacketRTCP,

Parameters

TUint8 * aEncryptedPayloadPtr

GetSenderROC()

TUint32 GetSenderROC()[virtual]

Get Sender Roll-Over Counter from RTP/SRTP packets defined by RCC mode

GetSequenceNumber()

TUint16 GetSequenceNumber()[protected]

Get_Concatenated_MDataL(TBool)

HBufC8 *Get_Concatenated_MDataL(TBoolrtcp)
Get the authentication portion for recv stream data For RTP this gets header and payload as authentication portion For RTCP it gets payload + SRTCP index
leave
KErrNone if success, system-wide error code otherwise

Parameters

TBool rtcpif it is rtcp packet

HeaderAndPayload()

TPtrC8 HeaderAndPayload()

Get header and encrypted portion, excluding possible MKI and authentication tag.

HeaderLength()

TUint HeaderLength()

Get header length.

MasterKeyIdentifier()

TPtrC8 MasterKeyIdentifier()[virtual]

virtual function for getting the MKI value, implemented in CSRTPPacketSRTP/CSRTPPacketSRTCP

PacketIndex()

TUint64 PacketIndex()[virtual]

virtual function for getting the packet index value, implemented in CSRTPPacketRTP

Payload()

TPtrC8 Payload()

Get payload entry. Here the "payload" denotes the encrypted portion (incl. RTCP/SRTCP).

PayloadLength()

TUint PayloadLength()

Get payload length (== length of the encrypted portion).

SequenceNumber()

TUint16 SequenceNumber()[virtual]

virtual function for getting the sequence number, implemented in CSRTPPacketRTP

SetPacketIndex(TUint64)

voidSetPacketIndex(TUint64aPacketIndex)[virtual]

virtual function for setting the packet index value, implemented in CSRTPPacketRTP

Parameters

TUint64 aPacketIndex

UpdatePayload()

voidUpdatePayload()[protected]

UpdatePayloadLengthL()

voidUpdatePayloadLengthL()[protected]
