Kurento JSON-RPC JoinRoom Method not found.

[d404...@googlemail.com]

Hi,

I have Kurento Media server running, but i am having trouble joining a room for an ios Client. I am using the KurentoToolbox pod in my project and it appears to be connecting properly as i get a callback to the delegate saying connected and in the kurento server logs i can see "Client connected from " so thats fine.

When i go to join a room or in that instance do any json rpc related calls, it seems to not be working correctly.

I have the server setup so that it connects to the json rpc client via this url https://serveraddress:8433/kurento and as mentioned, i am able to establish some form of connection, but when i then perform the join room method:

"Message: >{"jsonrpc":"2.0","method":"joinRoom","id":0,"params":{"user":"Andrew","room":"Andrews"}}"

Then it responds with:

"Response: >{"error":{"code":-32601,"message":"Method not found."},"id":0,"jsonrpc":"2.0"}"

Can anybody help me out? for joining a room does the json rpc url have to be different? i read somewhere it should be https://serveraddress:8433/room but that doesn't work either.

I have the demo java client working fine, so i believe that it is setup correctly and its probably likely the ios client is wrong or i am doing something wrong.

Thanks

Andrew.

Just incase anybody else gets stuck and there is nobody out there to help you out.

I needed to run a room server, so i used the kurento room server demo and that did the trick.

So you have the Media server running and then you have another process for the room server.

I am also facing the same issue. Did you get any workaround for this

So you fell into the same trap i did.

You need two instances, 1 - KMS 2 - Room server.

Basically running the kurento media server is not enough on its own(unless you do 1-1 and manage it all yourself). 

What you need to run is the room server instance too(that will create an api /room which takes the jsonrpc requests).

https://github.com/Kurento/kurento-room

And run the Kurento Room Server 

I hope that helps.

Hi Andrew ,

Thank you for the reply

I have installed the kurento- room  also in the server and running in  https://kivi.fibiweb.com:8443/

and media server running in  http://kivi.fibiweb.com:8888/kurento

and i am running kurentotoolbox in iOS 

in NBMRoomMainViewController

static NSString *defaultWsRoom = @"ws://kivi.fibiweb.com:8888/kurento";

static  NSString* const kRoomURLString = @"RoomServerURL";

I have also put url  https://kivi.fibiweb.com:8443/ in kRoomURLString

still i am getting

 did receive message: {

    error =     {

        code = "-32601";

        message = "Method not found.";

    };

    id = 0;

    jsonrpc = "2.0";

}

Thanks & Regards

Try changing the room url to be 

https://kivi.fibiweb.com:8443/room

That hopefully should work.

Basically you are using the room server to handle the peers and then feeds the actual video and audio via the KMS.

Hi , 

I have tried that too, but still get the error

I haven’t really got the time to debug it. 

Are you sure that port is open for access? 

[Renjith Rajendran]

it is open and accessible

https://kivi.fibiweb.com:8443 - This is getting in browser

&

https://kivi.fibiweb.com:8443/room - No url like this

Ah, just looked at some old code i had:

wss://serverUrl:8445/room

You need to run it either on WS or WSS for the room server.

I think defaultWsRoom should be wss://kivi.fibiweb.com:8443/room. That's the WS connection exposed by your room server. The connections are

Client ---------- wss://room-server-ip:8443/room ----> Room Server -------- ws://kms-ip:8888/kurento -----> KMS

That should clarify what's connecting where (as far as signalling goes), I hope.
