An application may create a descendent off this class and override functions as required for descibing a codec.

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. |
|
Get the main type of the capability. Always returns e_Video. Implements H323Capability. |
|
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.
Implemented in H323_H261Capability, and H323NonStandardVideoCapability. |

Implements H323Capability. |
|
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 FALSE then the received PDU codec description is not supported, so will be ignored. The default behaviour simply returns TRUE.

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).

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.
