Close()

IMPORT_C void

(

)

Closes the RTP packet.

InitRtpPacket(TRtpSendPacket *)

void

InitRtpPacket

(

TRtpSendPacket *

ptr

)

[private]

Parameters

TRtpSendPacket * ptr

Send()

IMPORT_C void

Send

(

)

Sends the RTP packet.

The packet must be correctly initialised, apart from the sequence number and the SSRC (the 32-bit numeric synchronisation source identifier).

The packet must continue to exist until it has been sent, i.e. until an ERtpSendSucceeded or an ERtpSendFailed event has been received on the RRtpSendSource .

panic: RTP 1 if the packet has not been opened. Note that this panic is raised in debug mode only; in release mode, calling this function when the packet has not been opened is likely to raise panics such as KERN-EXEC 3.

SendSync()

IMPORT_C TInt

SendSync

(

)

Sends the RTP packet.

The packet must be correctly initialised, apart from the sequence number and the SSRC (the 32-bit numeric synchronisation source identifier).

Sends the RTP data Synchronously.

panic: RTP 1 if the packet has not been opened. Note that this panic is raised in debug mode only; in release mode, calling this function when the packet has not been opened is likely to raise panics such as KERN-EXEC 3.

SetFlags(TUint)

IMPORT_C void

SetFlags

(

TUint

aFlags

)

Sets the first 32 bits of the packet header.

This function may be useful for profiles that do unusual things such as combining the payload type and marker bits, but should be used with extreme caution as no validity checking is done on the values passed in.

Note that the number passed in is in opposite endianess to that required by the packet. The function does not correct the endianess.

panic: RTP 1 if the packet has not been opened. Note that this panic is raised in debug mode only; in release mode, calling this function when the packet has not been opened is likely to raise panics such as KERN-EXEC 3.

RRtpPacket::Flags()

Parameters

TUint aFlags

The 32 bits. aFlags expected in this format.... V is most significant bit in aFlags 0 1 2 3 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 2 3 4 5 6 7 8 9 0 1 +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+ |V=2|P|X| CC |M| PT | sequence number | +-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+-+

SetMarker(TBool)

IMPORT_C void

SetMarker

(

TBool

aMark

)

Sets or unsets the RTP packet's marker bit.

panic: RTP 1 if the packet has not been opened. Note that this panic is raised in debug mode only; in release mode, calling this function when the packet has not been opened is likely to raise panics such as KERN-EXEC 3.

RRtpPacket::Marker()

Parameters

TBool aMark

ETrue, if the market bit is to be set, EFalse, if the marker bit is to be unset.

SetPayloadType(TUint)

IMPORT_C void

SetPayloadType

(

TUint

aPayloadType

)

Sets the RTP packet's payload type.

panic: RTP 1 if the packet has not been opened. Note that this panic is raised in debug mode only; in release mode, calling this function when the packet has not been opened is likely to raise panics such as KERN-EXEC 3.

panic: RTP 2 if the specified payload type value is greater than or equal to 128.

Parameters

TUint aPayloadType

The 7-bit payload type.

SetTimestamp(TUint)

IMPORT_C void

SetTimestamp

(

TUint

aTimestamp

)

Sets the RTP packet's timestamp

panic: RTP 1 if the packet has not been opened. Note that this panic is raised in debug mode only; in release mode, calling this function when the packet has not been opened is likely to raise panics such as KERN-EXEC 3.

RRtpPacket::Timestamp()

Parameters

TUint aTimestamp

The RTP packet timestamp

WritePayload()

IMPORT_C TDes8 &

WritePayload

(

)

Gets a modifiable descriptor into which the client can write the packet's payload.

panic: RTP 1 if the packet has not been opened. Note that this panic is raised in debug mode only; in release mode, calling this function when the packet has not been opened is likely to raise panics such as KERN-EXEC 3.
