An application may create a descendent off this class and override functions as required for descibing the codec.
H323GenericAudioCapability::H323GenericAudioCapability | ( | unsigned | maxPacketSize, | |
unsigned | desiredPacketSize, | |||
const PString & | capabilityId, | |||
PINDEX | maxBitRate = 0 | |||
) |
Create a new set of information about a non-standard codec.
maxPacketSize | Maximum size of an audio packet in frames |
desiredPacketSize | Desired transmit size of an audio packet in frames |
capabilityId | generic codec identifier |
maxBitRate | maxBitRate parameter for the GenericCapability |
Comparison H323GenericAudioCapability::Compare | ( | const PObject & | obj | ) | const |
Compare two capability instances. This compares the main and sub-types of the capability.
Reimplemented from H323Capability.
virtual unsigned H323GenericAudioCapability::GetSubType | ( | ) | const [virtual] |
Get the sub-type of the capability. This is a code dependent on the main type of the capability.
This returns H245_AudioCapability::e_genericCapability.
Implements H323Capability.
virtual BOOL H323GenericAudioCapability::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.
virtual BOOL H323GenericAudioCapability::OnReceivedPDU | ( | const H245_AudioCapability & | pdu, | |
unsigned & | packetSize | |||
) | [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 H323GenericCapabilityinfo::OnReceivedPDU() to handle the provided PDU.
pdu | PDU to get information from |
packetSize | Packet size to use in capability |
Reimplemented from H323AudioCapability.
virtual BOOL H323GenericAudioCapability::OnSendingPDU | ( | H245_AudioCapability & | pdu, | |
unsigned | packetSize | |||
) | 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 |
packetSize | Packet size to use in capability |
Reimplemented from H323AudioCapability.
