NAME
janus - WebRTC server/gateway
SYNOPSIS
janus [options]
DESCRIPTION
janus is a WebRTC server/gateway developed by Meetecho conceived to be a general purpose one. As such, it
doesn't provide any functionality per se other than implementing the means to set up a WebRTC media
communication with a browser or application, exchanging JSON messages with it over different transports,
and relaying RTP/RTCP and messages between clients and the server-side application logic they're attached
to. Any specific feature/application is provided by server side plugins, that browsers can then contact
via the gateway to take advantage of the functionality they provide. Example of such plugins can be
implementations of applications like echo tests, conference bridges, media recorders, SIP gateways and
the like.
The reason for this is simple: we wanted something that would have a small footprint (hence a C
implementation) and that we could only equip with what was really needed (hence pluggable modules). That
is, something that would allow us to deploy either a full-fledged WebRTC server on the cloud, or a small
nettop/box to handle a specific use case.

EXAMPLES
janus - Launch Janus with all options from configurations files
janus -b -L /tmp/januslog - Launch Janus as a daemon and log to the specified file
janus -6 - Launch Janus with IPv6 support enabled
janus -u -U - Launch Janus with rtcpmux and BUNDLE always forced on
BUGS
If you think you found a bug or want to contribute a feature, you can issue or a pull request on
https://github.com/meetecho/janus-gateway/issues.
Anyway, before doing that make sure you read the documentation at http://janus.conf.meetecho.com/docs/
and that it has not been discussed already at https://groups.google.com/forum/#!forum/meetecho-janus. We
only use Github for code issues, and NOT for configuration or usage issues: use the group for that.
