Janus as a WebRTC "enabler"

Having fun with RTP and external applications
UD2.208 (Decroly)
Lorenzo Miniero
This talk will cover several aspects related to Janus as a WebRTC "enabler" for non-WebRTC applications. In particular, it will focus on the RTP management in Janus, namely how to use it as input/output to interact with external applications for different use cases.

Janus is an open source and general purpose WebRTC server. Its modular nature makes it easy to implement heterogeneous multimedia applications based on WebRTC, whether it's for conferencing, talking to a SIP infrastructure, broadcast a stream or interacting with an IoT device. One of its strongest points is the ability to seamlessly involve plain RTP within the context of a WebRTC communication, whether it's for feeding media to a WebRTC endpoint, or use a WebRTC stream somewhere else: this makes Janus a good WebRTC "enabler" for platforms that may not be aware of, or be compliant with, the WebRTC specification.

This talk will cover the different features Janus provides implementers with, when it comes to RTP. In particular, it will introduce the Streaming plugin (RTP- and RTSP-to-WebRTC broadcaster), the SIP/NoSIP plugins (for legacy VoIP integration) and the so-called RTP forwarders (to relay media coming from WebRTC sources as plain RTP to external endpoints), and explain how these different components can be used together in different scenarios, whether it's just to increase scalability or to implement a complex and rich multimedia application. Besides, it will spend a few words on how simulcast, SRTP and recordings can be part of the picture.

For many years, Linphone has been one of the most active free communication software. Originally focused on voice, aditionnal functionalities were rapidly added like video, group chat and presence. All of these communication modes imply privacy. To achieve a good level of privacy, users must be able to ensure that their communications can only be displayed to the receiver of those communications, especially no-one from server infrastructure crossed by the messages shall be in the position of ...

This session will discuss how we can share infrastructure and resources between projects, with the goals of reducing administrative burdens, reducing duplication of effort and increasing interoperability between our solutions. To satisfy user expectations, interoperability is more critical in the field of real-time communications than any other free software eco-system. In particular, we will look at how to share management of an event calendar, Planet sites, repositories, CI for interop testing ...

The eXtensibility of XMPP makes it extremely powerful. But it is easy to get lost in the supermarket of extensions. In this talk I will guide you though the extensions: how to read the labels? How to cook some common recipes? I will also show some exotic but nice ingredients. And last but not least: we will be having some protocol-fun!

Matrix is an open source project developing an open protocol and network for decentralised end-to-end-encrypted communication, providing a viable open alternative to the proprietary communication silos of WhatsApp, Slack, Discord and friends. One of Matrix's main goals is to provide a highest-common-denominator open network which can bridge together existing communication silos. In this talk, we'll show off Bifröst, our new application framework for building bridges, and demonstrate high ...

The love for technology is what binds us and pushes us to keep improving. Though there are a lot of thriving RTC projects, collaboration between them is rare. This results in duplication of efforts, differing standards and lack of interoperability. In this session we will discuss the opportunities that lie in wait for the Free RTC space and how we're trying to tackle some of these issues through the Open VoIP Alliance. NOTE: This is a late addition to the schedule to fill a gap left by a speaker ...
