The Video Conferencing API is part of the LEADTOOLS Streaming Module, which adds onto the Multimedia SDK. For more information about the Multimedia Module, click here.
The following table describes the DLLs included in the Video Conferencing API.
Examples of the NetServer and NetClient functionality can be found in the following directories:
<LEADTOOLS_INSTALLDIR>\Examples\multimedia\ltmm\cpp\NetServer
<LEADTOOLS_INSTALLDIR>\Examples\multimedia\ltmm\cpp\NetClient
For a listing of examples and demos included with the toolkit, refer to DirectShow Example Programs and Demos for Win32/x64.
The "<LEADTOOLS_INSTALLDIR>" is the directory you specified during installation.
