I try to do a simpleWebRTC demo for screensharing. For my signalling server, I used the server.js file at: https://github.com/andyet/signalmaster/blob/master/server.js
However, when I run the file on my Ubuntu as server, and browse to the port where I specified, I get the error message:
{"code":0,"message":"Transport unknown"}
Without this server.js and using simpleWebRTC.com/latest.js as signalling channel, I am able to do video chat, but not screenshare, since the signalling server for that is on HTTP.
Any help would be really appreciated.
