TRtpOneShotness in Multimedia Protocols RTP

TRtpEventType

Description

A set of values that defines the event types that may be handled.

See all variants of the RegisterEventCallbackL() function.

`ERtpAnyEvent`	A special event type that is interpreted by all of the RegisterEventCallbackL() set of functions to mean that the registered callback function is to be called for any event except failure events.
`ERtpSessionEventBase`	Defines a base value for session events. All session event types have values that are greater than this.
`ERtpSessionFail`	An event type that indicates that a session-level error has occurred. The event status is a standard Symbian OS error code. The callback parameter is used to register interest in only one type of error.
`ERtpNewSource`	An event type that indicates that a new stream has been received. The event status is the SSRC of the stream.
`ERtpNewRR`	An event type that indicates that an RTCP RR (Receiver Report) has been received. The event status is the SSRC of the sender. Note - This event type has not been implemented yet.
`ERtpBufferOverflow`	An event type that indicates that a packet bigger than the expected maximum has been received. When this event occurs, the packet is deleted.
`ERtpUndersizedPacket`	An event type that indicates that a packet has been recived that is smaller than its header. When this event occurs, the packet is deleted.
`ERtpSessionEventEnd`	Not an event type, but defines the upper limit for session event type values.
`ERtpSendEventBase`	Not an event type but defines a base value for send stream events. All send stream event types have values that are greater than this.
`ERtpSendFail`	An event type that indicates that an error has occurred while sending a packet. The event status is a standard Symbian OS error code. The callback parameter is used only to register interest in one type of error.
`ERtpSendSucceeded`	An event type that indicates that a send packet operation has succeeded.
`ERtpSendEventEnd`	Not an event type, but defines the upper limit for send stream event type values.
`ERtpSourceEventBase`	Not an event type but defines a base value for receive stream events. All receive stream event types have values that are greater than this.
`ERtpSourceFail`	An event type that indicates that an error has occurred. The event status is a standard Symbian OS error code. The callback parameter is used only to register interest in one type of error.
`ERtpPacketReceived`	An event type that indicates that an in-sequence packet has been received.
`ERtpCodecChange`	An event type that indicates that the codec has changed. The event status is the new payload type.
`ERtpMarker`	An event type that indicates that a marker packet has arrived.
`ERtpMisorder`	An event type that indicates that a misordered packet has arrived.
`ERtpDropout`	An event type that indicates that a dropout has been detected.
`ERtpSDES`	An event type that indicates that a SDES (Source Description) RTCP packet has been received. For SDES events, the callback parameter is used to specify the type of SDES. Use a value from TRtpSendPacketType The event status is the SSRC of the sender.
`ERtpAPP`	An event type that indicates that a APP (Application Defined) RTCP packet has been received. The event status is the SSRC of the sender.
`ERtpSR`	An event type that indicates that a SR (Sender Report) RTCP packet has been received. The event status is the SSRC of the sender.
`ERtpRR`	An event type that indicates that a RR (Receiver Report) RTCP packet has been received. The event status is the SSRC of the sender.
`ERtpBYE`	An event type that indicates that a BYE (Goodbye) RTCP packet has been received. The event status is the SSRC of the sender.
`ERtpSourceEventEnd`	Not an event type, but defines the upper limit for receive stream event type values.

TRtpOneShotness

Description

Indicates whether a callback function can be called once, or more than once.

The appropriate enum value is passed as an argument to the RegisterEventCallbackL() functions of RRtpSessionRRtpSession, RRtpSendSourceRRtpSendSource, and RRtpReceiveSourceRRtpReceiveSource, or to the equivalent static functions.

`ERtpNotOneShot`	Indicates that the call back function can be called more than once.
`ERtpOneShot`	Indicates that the call back function is only called once.

const TInt KRtpNoExtension=-1;

Description

A value that can be passed as the second parameter in a call to either RRtpSendSource::NewSendPacketL(TInt,TInt) or RRtpSendSource::NewSendPacketLC(TInt,TInt) to indicate that no exension is required for the RTP send packet.
