An application may create a descendent off this class and override functions as required for descibing the codec.
H323GenericVideoCapability::H323GenericVideoCapability | ( | const PString & | capabilityId, | |
PINDEX | maxBitRate = 0 | |||
) |
Create a new set of information about a generic codec.
capabilityId | codec identifier, from H245 |
maxBitRate | maxBitRate parameter for the GenericCapability |
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::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.
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.
pdu | PDU to set information on |
Implements H323VideoCapability.
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.
pdu | PDU to set information on |
Implements H323VideoCapability.
virtual BOOL H323GenericVideoCapability::IsGenericMatch | ( | const H245_GenericCapability & | param | ) | const [inline, virtual] |
Compare the generic part of the capability, if applicable.
param | Generic field in PDU received |
Reimplemented from H323GenericCapabilityInfo.
