Record published items and playing them

[myltiks]

Hello all,

I am having some problems with the playback application. I created a CollectionNode, Node for a room and during recording my application publishes some items to this CollectionNode -> Node. My undertanding is that the record functionality should also record changes to published items (CollectionNode -> Node -> Item). I have not found any internet examples on how to implement playback using a custom CollectionNode. My initial thoughts were that to be able to playback a custom collection node I should subscribe to that collection node in the playback application like this:

                                        testCollectionNode = new CollectionNode();

                                        testCollectionNode.sharedID = "MyCustomCollectionName";

                                        testCollectionNode.connectSession = connectSession;

                                        testCollectionNode.addEventListener(CollectionNod eEvent.ITEM_RECEIVE, onUpdate);

                                        testCollectionNode.subscribe();

But when I do this  during playback I receive following error in the log:

Sorry for the delayed response. I think you are trying to view the playback with the wrong "permissions" and that's why you are getting an eror "cannot create property".

You should make sure the playback "viewer" has the appropriate permissions (for what I see from your logs you have a userID=0 and affiliation=10 that makes me think you are logging in as a "guest" for your playback app.

Hello Raff,

According with Adobe's specifications I have created this record with flag guestsAllowed=true, so as I understand guest should be available to view this record, and guest really is available to:

• View webcam record
• Listen audio record
• View screenshare record

But when I try to subscribe to collection nodes modifications - I get this error. I have tried to access as administrator, but stiil get the same error:

Probably LCCS playback feature not support playing custom collection nodes? I will send you in private my code.

Thank you in advance!

Hello Raff,

Also I noted that when I call C# API to receive current room state AccountManager.getNodes("gp000000000000000087", "/"), I receive result XML, which contains information about item SlideURL in collection:

Note please that I receive this XML from current room, NOT from recording. But looks like there are some bugs at LCCS side because actually it keeps items versions and time-stamps in the current room state- that's very strange. Also it is very strange that if I am using  LCCS SDK Navigator -> Room Console, then connect to room and try to explore - I see collection node (GoPresentManager) and Nodes(RoomState), but Items list is empty and I cannot add new items to this list.

Could you please explain it?

Cheers,

Nikita
