[Red5] Livestreaming: Check if a user is already publishing !

[Mathias Menrath]

Hi Walter,

thanks for your answer.
However, your solution would only work for a Java-based Client or for the RED5-server-application
itself. But in my case, i use a Flex-Client. That's why i define a new property for the sharedObject
by the "setProperty"-method (clientside way).
The serverside part of my sharedObject is:

/**SharedObject for streaming informations. */
private ISharedObject streamSo;
...

createSharedObject(myScope, "streamlist", false);
streamSo = getSharedObject(myScope, "streamlist");

I'm at a loss here.
Any further hint would be greatly appreciated.

Mathias

  Try to change:  if (soStream.data.id == "notPublishing")

  to:

   if (soStream.data.id.equals("notPublishing") );

    Hi,
    i want to use a Remote Shared Object to store the information if a specific user
    (with an unique user ID) is currently publishing or not, so that the "Play"-Button for
    all the other Receivers is getting enabled or disabled within the corresponding Video-
    Component.
    I thought i could simply do the following:

    1.  Setup the SharedObject for the streaming informations:

    soStream = SharedObject.getRemote( "streamlist", nc.uri, false );
    soStream.addEventListener( NetStatusEvent.NET_STATUS, soStreamNetStatusHandler );
    soStream.addEventListener( AsyncErrorEvent.ASYNC_ERROR, soStreamAsyncErrorHandler );
    soStream.addEventListener( SyncEvent.SYNC, soStreamSyncHandler );
    soStream.client = this;
    soStream.connect( nc ); 

    2.  Within my Video-Component: set the property for the sharedObject (as Sender) ...
                                                   ... and check this property (as Receiver)

    // "id" is a unique user ID (type String)

    As Sender:    soStream.setProperty(id, "notPublishing");  // by default 
                        soStream.setProperty(id, "publishing");      // when publishing

    As Receiver:   
                        if (soStream.data.id == "notPublishing")
                        {
                            btnAV.enabled = false; 
                        } 
                        else if (soStream.data.id == "publishing")
                        {
                            btnAV.enabled = true;
                            title += "-> ON AIR";
                            setStyle("backgroundColor", "yellow")
                        }

    However:  Neither the first if-block (blue) nor the second one (green) are getting called !!!
                   Though the data in the sharedObject is definately getting set by the Sender.

    Any ideas what could be the problem here ?
