An application may create a descendent off this class and override functions as required for descibing a codec.
| virtual unsigned H323VideoCapability::GetDefaultSessionID | ( | ) | const [virtual] |
Get the default RTP session. This function gets the default RTP session ID for the capability type. For example audio capabilities return the value RTP_Session::DefaultAudioSessionID etc.
The default behaviour returns zero, indicating it is not an RTP based capability.
Reimplemented from H323Capability.
| virtual MainTypes H323VideoCapability::GetMainType | ( | ) | const [virtual] |
Get the main type of the capability. Always returns e_Video.
Implements H323Capability.
| virtual PBoolean H323VideoCapability::OnReceivedPDU | ( | const H245_VideoCapability & | pdu, | |
| CommandType | type | |||
| ) | [virtual] |
| pdu | PDU to get information from |
| type | Type of PDU to send in |
Reimplemented in H323GenericVideoCapability, H323ExtendedVideoCapability, and H323H239VideoCapability.
| virtual PBoolean H323VideoCapability::OnReceivedPDU | ( | const H245_VideoCapability & | pdu | ) | [virtual] |
This function is called whenever and incoming TerminalCapabilitySet or OpenLogicalChannel PDU has been used to construct the control channel. It allows the capability to set from the PDU fields, information in members specific to the class.
The default behaviour is pure.
| pdu | PDU to set information on |
Reimplemented in H323H261PluginCapability, H323H263PluginCapability, and H323NonStandardVideoCapability.
| virtual PBoolean H323VideoCapability::OnReceivedPDU | ( | const H245_DataType & | pdu, | |
| PBoolean | receiver | |||
| ) | [virtual] |
This function is called whenever and incoming OpenLogicalChannel PDU has been used to construct the control channel. It allows the capability to set from the PDU fields, information in members specific to the class.
The default behaviour is pure.
| pdu | PDU to get information from |
| receiver | Is receiver OLC |
Reimplemented from H323Capability.
| virtual PBoolean H323VideoCapability::OnReceivedPDU | ( | const H245_Capability & | pdu | ) | [virtual] |
This function is called whenever and incoming TerminalCapabilitySet PDU is received on the control channel, and a new H323Capability descendent was created. This completes reading fields from the PDU into the classes members.
If the function returns PFalse then the received PDU codec description is not supported, so will be ignored. The default behaviour simply returns PTrue.
| pdu | PDU to get information from |
Reimplemented from H323Capability.
| virtual PBoolean H323VideoCapability::OnSendingPDU | ( | H245_VideoMode & | pdu | ) | const [pure virtual] |
This function is called whenever and outgoing RequestMode PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.
The default behaviour sets the PDUs tag according to the GetSubType() function (translated to different enum).
| pdu | PDU to set information on |
Implemented in H323H261PluginCapability, H323H263PluginCapability, H323NonStandardVideoCapability, H323GenericVideoCapability, and H323ExtendedVideoCapability.
| virtual PBoolean H323VideoCapability::OnSendingPDU | ( | H245_VideoCapability & | pdu, | |
| CommandType | type | |||
| ) | const [virtual] |
| pdu | PDU to set information on |
| type | Type of PDU to send in |
Reimplemented in H323GenericVideoCapability, H323ExtendedVideoCapability, and H323H239VideoCapability.
| virtual PBoolean H323VideoCapability::OnSendingPDU | ( | H245_VideoCapability & | pdu | ) | const [virtual] |
This function is called whenever and outgoing TerminalCapabilitySet or OpenLogicalChannel PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.
The default behaviour is pure.
| pdu | PDU to set information on |
Reimplemented in H323H261PluginCapability, H323H263PluginCapability, and H323NonStandardVideoCapability.
| virtual PBoolean H323VideoCapability::OnSendingPDU | ( | H245_ModeElement & | pdu | ) | const [virtual] |
This function is called whenever and outgoing RequestMode PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.
The default behaviour calls the OnSendingPDU() function with a more specific PDU type.
| pdu | PDU to set information on |
Implements H323Capability.
| virtual PBoolean H323VideoCapability::OnSendingPDU | ( | H245_DataType & | pdu | ) | const [virtual] |
This function is called whenever and outgoing OpenLogicalChannel PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.
The default behaviour calls the OnSendingPDU() function with a more specific PDU type.
| pdu | PDU to set information on |
Reimplemented from H323Capability.
| virtual PBoolean H323VideoCapability::OnSendingPDU | ( | H245_Capability & | pdu | ) | const [virtual] |
This function is called whenever and outgoing TerminalCapabilitySet PDU is being constructed for the control channel. It allows the capability to set the PDU fields from information in members specific to the class.
The default behaviour calls the OnSendingPDU() function with a more specific PDU type.
| pdu | PDU to set information on |
Implements H323Capability.
