Constructor & Destructor Documentation

H323_RTPChannel::H323_RTPChannel ( H323Connection connection,
const H323Capability capability,
Directions  direction,
RTP_Session rtp 
)

Create a new channel.

Parameters:
connection Connection to endpoint for channel
capability Capability channel is using
direction Direction of channel
rtp RTP session for channel

H323_RTPChannel::~H323_RTPChannel (  ) 

Destroy the channel.


Member Function Documentation

void H323_RTPChannel::AddFilter ( const PNotifier &  filterFunction  ) 

virtual void H323_RTPChannel::CleanUpOnTermination (  )  [virtual]

This is called to clean up any threads on connection termination.

Reimplemented from H323Channel.

virtual unsigned H323_RTPChannel::GetSessionID (  )  const [virtual]

Indicate the session number of the channel. Return session for channel. This returns the session ID of the RTP_Session member variable.

Reimplemented from H323Channel.

PTimeInterval H323_RTPChannel::GetSilenceDuration (  )  const

virtual BOOL H323_RTPChannel::OnReceivedAckPDU ( const H245_H2250LogicalChannelAckParameters param  )  [virtual]

This is called after a request to create a channel occurs from the local machine via the H245LogicalChannelDict::Open() function, and the request has been acknowledged by the remote endpoint.

The default behaviour sets the remote ports to send UDP packets to.

Parameters:
param Acknowledgement PDU

Implements H323_RealTimeChannel.

virtual BOOL H323_RTPChannel::OnReceivedPDU ( const H245_H2250LogicalChannelParameters param,
unsigned &  errorCode 
) [virtual]

This is called after a request to create a channel occurs from the local machine via the H245LogicalChannelDict::Open() function, and the request has been acknowledged by the remote endpoint.

The default behaviour sets the remote ports to send UDP packets to.

Parameters:
param Acknowledgement PDU
errorCode Error on failure

Implements H323_RealTimeChannel.

virtual BOOL H323_RTPChannel::OnSendingPDU ( H245_H2250LogicalChannelParameters param  )  const [virtual]

Fill out the OpenLogicalChannel PDU for the particular channel type.

Parameters:
param Open PDU to send.

Implements H323_RealTimeChannel.

virtual void H323_RTPChannel::OnSendOpenAck ( H245_H2250LogicalChannelAckParameters param  )  const [virtual]

This is called when request to create a channel is received from a remote machine and is about to be acknowledged.

Parameters:
param Acknowledgement PDU

Implements H323_RealTimeChannel.

virtual BOOL H323_RTPChannel::Open (  )  [virtual]

Open the channel.

Reimplemented from H323Channel.

H323_RTPChannel::PLIST ( FilterList  ,
PNotifier   
) [protected]

virtual void H323_RTPChannel::Receive (  )  [virtual]

Handle channel data reception.

This is called by the thread started by the Start() function and is typically a loop writing to the codec and reading from the transport (eg RTP_session).

Implements H323Channel.

void H323_RTPChannel::RemoveFilter ( const PNotifier &  filterFunction  ) 

virtual void H323_RTPChannel::Transmit (  )  [virtual]

Handle channel data transmission.

This is called by the thread started by the Start() function and is typically a loop reading from the codec and writing to the transport (eg an RTP_session).

Implements H323Channel.
