[VideoConference] Check how many people are on camera

Hi all,
I'm playing around with the VideoConference sample. Is there a way to check how many people are on camera?
I see every liveCast gets an id. My goal is to prevent users from starting broadcasting, as soon as there are 8 people on cam. I tried something like this in VideoConference.as:
Code: Select all
if(!videoContainer.contains(liveCast.8)
{
bt_joinConf.enabled = false;
bt_leaveConf.enabled = true;
}Am I on the right track? I think I'm overlooking something..

You can use the AVCastManager.getAvailableCasts() method. The list of LiveCast objects returned can be used to determine how many users are sending their stream in the current Room.

Hi Bax,
Thank you for your reply. The aim is to check if there are 8 users on cam. If there are 8 users broadcasting, I want the JoinConference button to be inactive.
How can I let it check there are 8 people on cam? Through getAvailableCasts I only get DisplayObject errors..

DId you check the API documentation of that method? It returns an array of object, one for each active stream. If the list contains 8 items, then 8 users are on cam.

Hi Bax,
I checked it and used it in my code. But now the length of getAvailableCasts is always 0. And yes, I joined the room already.
This is the code I used:
Code: Select all
public function onLiveCastPublished(evt:RedBoxCastEvent):void
{
var liveCast:LiveCast = evt.params.liveCast;
trace ("User " + liveCast.username + " published his live cast");
// Subscribe live cast and add to video container
addLiveCast(liveCast);
countcasts();
}Code: Select all
public function countcasts():void
{
// Retrieve live casts
var castsArray:Array = avCastMan.getAvailableCasts();
trace("LENGTH :", castsArray.length);
}Even if I trace it like: trace("LENGTH :", avCastMan.getAvailableCasts().length); - the length is always 0.

I'm sorry, I made a mistake. The array returned by the avCastMan.getAvailableCasts() method is an associative array, which means that the length property doesn't work.
You have to run a for-loop and count the items, like this:
Code: Select all
var cnt:int = 0;
for each (var lc:LiveCast in castsArray)
cnt++;
