Detailed Description

This class describes the G.711 codec capability.

Member Enumeration Documentation

enum H323_G711Capability::Mode

Specific G.711 encoding algorithm.

Enumerator
ALaw	European standard.
muLaw	American standard.

enum H323_G711Capability::Speed

Specific G.711 encoding bit rates.

Enumerator
At64k	European standard.
At56k	American standard.

Constructor & Destructor Documentation

H323_G711Capability::H323_G711Capability	(	Mode	mode = muLaw,
		Speed	speed = At64k
	)

Create a new G.711 capability.

Parameters

mode	Type of encoding.
speed	Encoding bit rate.

Member Function Documentation

virtual PObject* H323_G711Capability::Clone ( ) const

virtual

Create a copy of the object.

virtual PString H323_G711Capability::GetFormatName ( ) const

virtual

Get the name of the media data format this class represents.

Implements H323Capability.

virtual unsigned H323_G711Capability::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.
