Detailed Description

This class describes the interface to an H245 "generic" video codec used to transfer data via the logical channels opened and managed by the H323 control channel.

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


Constructor & Destructor Documentation

H323GenericVideoCapability::H323GenericVideoCapability ( const PString &  capabilityId,
PINDEX  maxBitRate = 0 
)

Create a new set of information about a generic codec.

Parameters:
capabilityId  codec identifier, from H245
maxBitRate  maxBitRate parameter for the GenericCapability


Member Function Documentation

Comparison H323GenericVideoCapability::Compare ( const PObject &  obj  )  const

Compare two capability instances. This compares the main and sub-types of the capability.

Reimplemented from H323Capability.

virtual unsigned H323GenericVideoCapability::GetSubType (  )  const [virtual]

Get the sub-type of the capability. This is a code dependent on the main type of the capability.

This returns one of the four possible combinations of mode and speed using the enum values of the protocol ASN H245_AudioCapability class.

Implements H323Capability.

virtual BOOL H323GenericVideoCapability::IsGenericMatch ( const H245_GenericCapability param  )  const [inline, virtual]

Compare the generic part of the capability, if applicable.

Parameters:
param  Generic field in PDU received

Reimplemented from H323GenericCapabilityInfo.

virtual BOOL H323GenericVideoCapability::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 calls H323NonStandardCapabilityinfo::OnReceivedPDU() to handle the provided PDU.

Parameters:
pdu  PDU to set information on

Implements H323VideoCapability.

virtual BOOL H323GenericVideoCapability::OnSendingPDU ( H245_VideoMode 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 H323GenericCapabilityinfo::OnSendingPDU() to handle the PDU.

Parameters:
pdu  PDU to set information on

Implements H323VideoCapability.

virtual BOOL H323GenericVideoCapability::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 calls H323GenericCapabilityinfo::OnSendingPDU() to handle the PDU.

Parameters:
pdu  PDU to set information on

Implements H323VideoCapability.
