Dear FIWARE coach,
we forward you a support request received from a CreatiFI applicant we are
not able to solve.
Please let us know if you need direct contact with the submitter.
Thanks.

*********************************

We are using kurento to stream and save videos of users webcams and
screens. We have this working but it is not always working. Sometimes we
get a failure but we do not have indication in the client that the
connection failed. Sometimes we have the screen record but the webcam
fails, sometimes the reverse, sometimes both fail.

We have a nodejs app in front of our kurento server managing the
connection. We listen to OnIceComponentStateChanged and MediaStateChanged
of the WebRtcEndpoint. Sometimes I see in my logs that the
OnIceComponentStateChanged goes GATHERING, CONNECTING and then nothing past
this and does not get to READY.

Question is - how can we detect that the connection cannot happen and
properly notify in the client?

In my client I use the kurento utils and with WebRtcPeer.WebRtcPeerSendonly
I pass an error function but I do not see this being called.

thanks
Paul
