| dataPort | Data port (control is dataPort+1) |
| virtual unsigned H323_ExternalRTPChannel::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.
| virtual PBoolean H323_ExternalRTPChannel::GetMediaTransportAddress | ( | OpalTransportAddress & | data, | |
| OpalTransportAddress & | control | |||
| ) | const [virtual] |
Get the media transport address for the connection. This is primarily used to determine if media bypass is possible for the call between two connections.
The default behaviour returns PFalse.
| data | Data channel address |
| control | Control channel address |
Reimplemented from H323Channel.
| virtual PBoolean H323_ExternalRTPChannel::Start | ( | ) | [virtual] |
Start the channel.
Reimplemented from H323UnidirectionalChannel.
| virtual void H323_ExternalRTPChannel::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).
| virtual void H323_ExternalRTPChannel::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).
| virtual PBoolean H323_ExternalRTPChannel::OnSendingPDU | ( | H245_H2250LogicalChannelParameters & | param | ) | const [virtual] |
Fill out the OpenLogicalChannel PDU for the particular channel type.
| param | Open PDU to send. |
Implements H323_RealTimeChannel.
| virtual void H323_ExternalRTPChannel::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.
| param | Acknowledgement PDU |
Implements H323_RealTimeChannel.
| virtual PBoolean H323_ExternalRTPChannel::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.
| param | Acknowledgement PDU |
| errorCode | Error on failure |
Implements H323_RealTimeChannel.
| virtual PBoolean H323_ExternalRTPChannel::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.
| param | Acknowledgement PDU |
Implements H323_RealTimeChannel.
