Janus WebRTC Gateway

Janus is an open source, general purpose, WebRTC gateway designed and developed by Meetecho. This version of the gateway can only be installed on Linux systems: next versions will take into account cross compilation on different environments.

For some online demos and documentations, make sure you pay the project website a visit!

To discuss Janus with us and other users, there's a Google Group called meetecho-janus that you can use. If you encounter issues, though, please submit an issue on github instead.

Dependencies

To install it, you'll need to satisfy the following dependencies:

  • Jansson
  • libnice
  • OpenSSL (at least v1.0.1e)
  • libsrtp (at least v1.5 suggested)
  • Sofia-SIP
  • usrsctp (only needed if you are interested in Data Channels)
  • libmicrohttpd (only needed if you are interested in REST support for the Janus API)
  • libwebsockets (only needed if you are interested in WebSockets support for the Janus API)
  • cmake (only needed if you are interested in WebSockets and/or BoringSSL support, as they make use of it)
  • rabbitmq-c (only needed if you are interested in RabbitMQ support for the Janus API)

A couple of plugins depend on a few more libraries:

  • libopus (only needed for the bridge plugin)
  • libogg (only needed for the voicemail plugin)

Additionally, you'll need the following libraries and tools:

All of those libraries are usually available on most of the most common distributions. Installing these libraries on a recent Fedora, for instance, is very simple:

yum install libmicrohttpd-devel jansson-devel libnice-devel \
   openssl-devel libsrtp-devel sofia-sip-devel glib-devel \
   opus-devel libogg-devel pkgconfig gengetopt libtool autoconf automake

Notice that you may have to yum install epel-release as well if you're attempting an installation on a CentOS machine instead.

On Ubuntu or Debian, it would require something like this:

aptitude install libmicrohttpd-dev libjansson-dev libnice-dev \
    libssl-dev libsrtp-dev libsofia-sip-ua-dev libglib2.0-dev \
    libopus-dev libogg-dev pkg-config gengetopt libtool automake
  • Note: please notice that libopus may not be available out of the box on Ubuntu or Debian, unless you're using a recent version (e.g., Ubuntu 14.04 LTS). In that case, you'll have to install it manually.

If your distro ships a pre-1.5 version of libsrtp, it may be better to uninstall that version and install 1.5 manually. In fact, 1.4.x is known to cause several issues with WebRTC. Installation is quite straightforward:

wget https://github.com/cisco/libsrtp/archive/v1.5.0.tar.gz
tar xfv v1.5.0.tar.gz
cd libsrtp-1.5.0
./configure --prefix=/usr --enable-openssl
make libsrtp.so && sudo make install
  • Note: you may need to pass --libdir=/usr/lib64 to the configure script if you're installing on a x86_64 distribution.

If you want to make use of BoringSSL instead of OpenSSL for any reason (read here for some background on this), you'll have to manually install a specific version of the library to a specific location. Use the following steps:

git clone https://boringssl.googlesource.com/boringssl
cd boringssl
# We need a specific revision
git checkout 12fe1b25ead258858309d22ffa9e1f9a316358d7
# Don't barf on errors
sed -i s/" -Werror"//g CMakeLists.txt
# Build
mkdir -p build
cd build
cmake -DCMAKE_CXX_FLAGS="-lrt" ..
make
cd ..
# Install
sudo mkdir -p /opt/boringssl
sudo cp -R include /opt/boringssl/
sudo mkdir -p /opt/boringssl/lib
sudo cp build/ssl/libssl.a /opt/boringssl/lib/
sudo cp build/crypto/libcrypto.a /opt/boringssl/lib/

Once the library is installed, you'll have to pass an additional --enable-boringssl flag to the configure script, as by default Janus will be build assuming OpenSSL will be used. If you were using OpenSSL and want to switch to BoringSSL, make sure you also do a make clean in the Janus folder before compiling with the new BoringSSL support.

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:

git clone https://github.com/sctplab/usrsctp
cd usrsctp
./bootstrap
./configure --prefix=/usr && make && sudo make install
  • Note: you may need to pass --libdir=/usr/lib64 to the configure script if you're installing on a x86_64 distribution.

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:

git clone git://git.libwebsockets.org/libwebsockets
cd libwebsockets
# If you want the stable version of libwebsockets, uncomment the next line
# git checkout v1.5-chrome47-firefox41
mkdir build
cd build
cmake -DCMAKE_INSTALL_PREFIX:PATH=/usr -DCMAKE_C_FLAGS="-fpic" ..
make && sudo make install
  • Note: if libwebsockets.org is unreachable for any reason, replace the first line with this:

    git clone https://github.com/warmcat/libwebsockets.git

Finally, the same can be said for rabbitmq-c as well, which is needed for the optional RabbitMQ support. In fact, several different versions of the library can be found, and the versions usually available in most distribution repositories are not up-do-date with respect to the current state of the development. As such, if you're interested in integrating RabbitMQ queues as an alternative (or replacement) to HTTP and/or WebSockets to control Janus, you can install the latest version with the following steps:

git clone https://github.com/alanxz/rabbitmq-c
cd rabbitmq-c
git submodule init
git submodule update
autoreconf -i
./configure --prefix=/usr && make && sudo make install
  • Note: you may need to pass --libdir=/usr/lib64 to the configure script if you're installing on a x86_64 distribution.

To conclude, should you be interested in building the gateway documentation as well, you'll need some additional tools too:

On Fedora:

yum install doxygen graphviz

On Ubuntu/Debian:

aptitude install doxygen graphviz

Compile

Once you have installed all the dependencies, get the code:

git clone https://github.com/meetecho/janus-gateway.git
cd janus-gateway

Then just use:

sh autogen.sh

to generate the configure file. After that, configure and compile as usual to start the whole compilation process:

./configure --prefix=/opt/janus
make
make install

Since Janus requires configuration files for both the core and its modules in order to work, you'll probably also want to install the default configuration files to use, which you can do this way:

make configs

Remember to only do this once, or otherwise a subsequent make configs will overwrite any configuration file you may have modified in the meanwhile.

If you're not interested in Data Channels, WebSockets and/or RabbitMQ (or you don't care about either of them) you can disable them when configuring:

./configure --disable-websockets --disable-data-channels --disable-rabbitmq

If Doxygen and graphviz are available, the process can also build the documentation for you. By default the compilation process will not try to build the documentation, so if you instead prefer to build it, use the --enable-docs configuration option:

./configure --enable-docs

You can also selectively enable/disable other features (e.g., specific plugins you don't care about). Use the --help option when configuring for more info.

Configure and start

To start the gateway, you can use the janus executable. There are several things you can configure, either in a configuration file:

<installdir>/etc/janus/janus.cfg

or on the command line:

<installdir>/bin/janus --help

                              requests  (default=off)

Options passed through the command line have the precedence on those specified in the configuration file. To start the gateway, simply run:

<installdir>/bin/janus

This will start the gateway, and have it look at the configuration file.

As far as transports are concerned (that is, with respect to how you can interact with your Janus instance), using the default configuration files provided after issuing a make configs will result in Janus only enabling an HTTP webserver (port 8088) and a plain WebSocket server (8188), assuming the related transport modules have been compiled, of course. To enable HTTPS or Secure WebSockets support, edit the related transport configuration file accordingly. You can also change the base path that the webserver uses: by default this is /janus, but you can change it to anything you want and with any nesting you want (e.g., /mypath, /my/path, or /my/really/nested/path). This is done to allow you to more easily customize rules in any frontend you may have (e.g., Apache in front of your services). Please notice that the path configuration is not provided for WebSockets, instead, as it is not needed there. The RabbitMQ module, if compiled, is disabled by default, so you'll have to enable it manually if interested in it.

To test whether it's working correctly, you can use the demos provided with this package in the html folder: these are exactly the same demos available online on the project website. Just copy the file it contains in a webserver, or use a userspace webserver to serve the files in the html folder (e.g., with php or python), and open the index.html page in either Chrome or Firefox. A list of demo pages exploiting the different plugins will be available. Remember to edit the transport/port details in the demo JavaScript files if you changed any transport-related configuration from its defaults.

Help us!

Any thought, feedback or (hopefully not!) insult is welcome!
