Janus

Janus is a [[WebRTC]] Server

Installation

On Ubuntu 22.04

To make sure that you OS is updated to date

apt-get update

Install dependencies

apt-get install -y libmicrohttpd-dev libjansson-dev libssl-dev libsrtp2-dev libsofia-sip-ua-dev libglib2.0-dev libopus-dev libogg-dev libcurl4-openssl-dev liblua5.3-dev libconfig-dev pkg-config libtool automake autoconf git cmake

Install libnice because the available version in Ubuntu usually case problems.

`libnice` require `meson`, `ninja` and Python 3

```bash
apt-get install meson ninja-build
```

git clone https://gitlab.freedesktop.org/libnice/libnice
cd libnice
meson --prefix=/usr build && ninja -C build && ninja -C build install

For what concerns usrsctp, which is needed for Data Channels support, it is usually not available in repositories, so if you're interested in them (support is optional) you'll have to install it manually. It is a pretty easy and standard process:

cd /
git clone https://github.com/sctplab/usrsctp
cd usrsctp
./bootstrap
./configure --prefix=/usr --disable-programs --disable-inet --disable-inet6
make && make install

The same applies for libwebsockets, which is needed for the optional WebSockets support. If you're interested in supporting WebSockets to control Janus, as an alternative (or replacement) to the default plain HTTP REST API, you'll have to install it manually:

cd /
git clone https://libwebsockets.org/repo/libwebsockets
# If libwebsockets.org cannot be reached, please use https://github.com/warmcat/libwebsockets.git
cd libwebsockets
# If you want the stable version of libwebsockets, uncomment the next line
# git checkout v3.2-stable
mkdir build
cd build
# See https://github.com/meetecho/janus-gateway/issues/732 re: LWS_MAX_SMP
# See https://github.com/meetecho/janus-gateway/issues/2476 re: LWS_WITHOUT_EXTENSIONS
cmake -DLWS_MAX_SMP=1 -DLWS_WITHOUT_EXTENSIONS=0 -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_C_FLAGS="-fpic" ..
make && make install

The same applies for Eclipse Paho MQTT C client library (if needed), which is needed for the optional MQTT support. If you're interested in integrating MQTT channels as an alternative (or replacement) to HTTP and/or WebSockets to control Janus, or as a carrier of Janus Events, you can install the latest version with the following steps:

cd /
git clone https://github.com/eclipse/paho.mqtt.c.git
cd paho.mqtt.c
make && make install

Nanomsg support (if needed): apt-get install libnanomsg-dev

RabbitMQ support (if needed):

cd /
git clone https://github.com/alanxz/rabbitmq-c
cd rabbitmq-c
git submodule init
git submodule update
mkdir build && cd build
cmake -DCMAKE_INSTALL_PREFIX=/usr ..
make && make install

• Note: you may need to pass --libdir=/usr/lib64 to the configure script if you're installing on a x86_64 distribution.
