Пакет janus: Информация

Janus is a general purpose WebRTC Gateway with a minimal footprint.

As such, it provides no functionality per se other than implementing
the means to set up a WebRTC media communication with a browser,
exchanging JSON messages with it, and relaying RTP/RTCP and messages
between browsers and the server-side application logic they are
attached to. Any specific feature/application are implemented in
server side plugins, that browsers contact via the gateway to take
advantage of the functionality they provide.

Example uses for Janus are applications involving echo tests,
conference bridges, media recorders, and SIP gateways.
