Abrar, I searched through the pdf document but did not find 'getLiveStreamStats';
nc.call('getLiveStreamStats', new onGetLiveStreamStats(), demo.text, demo1.text);
implies that 'getLiveStreamStats' is either a custom or an inherent method running in an application.asp on the FCS;
I expect that it is a custom built method and that it is capable of only returning the 'Server-Side Information Objects ... Stream information objects';
as far as your question goes:
in order to get a list of users ( 'subscribers' , 'publishers') you will need to build your own custom functions;
CLIENTSIDE
1 - you need to know what kind of information you want from each user: username, password, etc
2 - nc.connect( the_url , prop1 , prop2 , ... )
SERVERSIDE
1 - application.onConnect = function ( clientObj , prop1, prop2, ... ){ ... }
2 - you need a way to store all of the users informations in one place - an array(s)
3 - you need to build the methods that you want to go through the array(s) to get the info out
