Janus plugin to serve as a WebRTC Selective Forwarding Unit (SFU) for game networking data. It's the current backend for Mozilla Hubs.

In the future, this is likely to grow into a reverse proxy for Reticulum, a kind of generalized, stateful, sharded WebVR networking backend. But right now it's mostly just for being a simple, plug-and-play, star-topology SFU that you can use instead of being peer-to-peer.

See here for API documentation on how to communicate with the plugin.

PRs and GitHub issues are welcome.

This is a plugin for Janus, so you'll need to install and run Janus first. The installation instructions on GitHub are canonical. It's compatible with versions of Janus more recent than 0.4.0.

This plugin should be compatible with any OS that can run Janus; that includes Linux, OS X, and Windows via WSL. If you use a version from a package manager, you might want to check to make sure it has data channel support, which is a compile-time option. (Debian and Ubuntu have it.) Alternatively, you can try running scripts/setup-and-run-janus.sh, which will compile and install Janus and its dependencies for you.

$ sudo apt install libglib2.0-dev libjansson-dev

$ cargo build [--release]

$ cargo test

Install the library output by the build process (e.g. ./target/release/libjanus_plugin_sfu.so) into the Janus plugins directory (e.g. /usr/lib/janus/plugins). Restart Janus to activate.
