Yes, like the error says, you have to use wss on pages served via https. 
Furthermore, Chrome requires the use of https when you want to use 
getUserMedia.
See here: 
https://developers.google.com/web/updates/2015/10/chrome-47-webrtc?hl=en. It 
says: " Starting with Chrome 47, getUserMedia() requests are only 
allowed from secure origins: HTTPS or localhost."

The solution for development is, to host the webrtc client locally, so 
that you load the page from localhost. In that case getUserMedia is 
allowed with http, too (as the quote says). That means you have to 
download the dubango client and run a webserver on your dev machine.

Unfortunately, there is not much documentation about this, as far as I 
can tell.
