A viral chat / WebRTC client

Merci d'activer JavaScript dans votre navigateur,
sans quoi certaines parties du site ne fonctionneront pas !

chat with public/private messages + emotes
upload/sharing of pictures < 2Mo
audio/video webrtc client
desktop sharing in read only mode
clients for desktop and mobile
license GPLv2 (so real free software, and not industrial open source)
tested with Firefox and Chromium - forget IE/Edge - no interest to loose my time with microsoft
TODO : client translation in others languages - help wanted !
TODO : use a FSU server instead of the current TURN/STUN server in mesh mode, to avoid disconnections of people with slow upload bandwith - especially those connected in ADSL.

You need a Virtual Private Server in the cloud, with apache2+letsencrypt already installed and running.
Then you must set a STUN/TURN server to relay audio/video trafic between peers. I choose the coturn package from the Ubuntu, but any other STUN/TURNS server should work. Just remember than TURNS listen incoming connections on the TCP 5349 port, and use the UDP range from 49152 to 65535, so if you use a firewall, be aware to let these ports open !
Then you need the server part of Pandemy, to provide a websocket, listening on a public TCP port > 1024. This websocket will relay text messages and pictures from the chat, and text signals beetween WebRTC peers.
Then finally, you just need to install the Pandemy clients on your web server : one for desktops and the other for mobiles devices.
That's all folks !

The HOWTO files, in both server and client archives, will help you to configure Pandemy on your own VPS.
