Create a new H261 Capability |
|
Create a copy of the object. |
|
Compare object Reimplemented from H323Capability. |
|
Create the codec instance, allocating resources as required.
Implements H323Capability. |
|
Get cifMPI |
|
Get the name of the media data format this class represents. Implements H323Capability. |
|
Get maximum bit rate |
|
Get qcifMPI |
|
Get still image transmission flag |
|
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. |
|
Get temporal/spatial tradeoff capabilty |
|
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 gets the data rate field from the PDU.
Implements H323VideoCapability. |
|
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 resolution and bit rate.
