Dear FIWARE coach,
as you suggested we collect more info from the CreatiFI winner (moreover
they attached configuration files) and we forward you the support request,
we
are not able to solve.
Please let us know if you need direct contact with the submitter.
Thanks.
**************************************************************
We are trying to develop an application with Kurento GE as part of CREATIFI
project.
The application is quite simple for now, but we are facing some technical
issues.
The application uses SignalMaster as signaling server, and Kurento for
mediating the video communication.
We started with a peer webrtc mini-prototype, and now we are integrating
Kurento …
Our environment is:
Linux Ubuntu 14.10
SignalMaster https://github.com/andyet/signalmaster
Kurento Media Server (5.1.0)
Kurento Client Nodejs 5.1.0
The code I have so far does …
- allows two clients to register to a ‘room’
- when the second enters the room, SDP offers are exchanged (using signal
master functionalities)
- then I try to integrate Kurento in the process to have the media exchange
handled by Kurento but unfortunately, the whole process does not fulfill
because even in a loopback case (clients and servers all running in same
machine)I cannot see the videostream to appear.
In attachment you find the code excerpts.
I think in this stage of the project it would be great for us to get your
inputs.
A second design problem which is not clear to us - but we are not yet there
- is the role / configuration of STUN / TURN servers.
In the peer webrtc mini-prototype we figured out the architecture, but we
do not understand how this has to change using Kurento.
Can you help and help us go in the right direction ?
best regards
