New Features

The Dialogic

Conferencing (CNF) API library provides the following new capabilities in

Dialogic

HMP Software 4.1LIN:

Multimedia (audio/video) conferencing

Provides the ability to combine images from conference participants into a single

image viewed by the conference participants. Several functions and data structures

are added to support multimedia conferencing, including cnf_SetVideoLayout( ),

cnf_GetVideoLayout( ), cnf_SetVisiblePartyList( ), and

cnf_GetVisiblePartyList( ).

Library”, on page 27). This layout is then set or applied to a multimedia conference

using cnf_SetVideoLayout( ).
