Sylk

Sylk is a WebRTC client focused on multiparty video conferencing. Sylk is the companion client for SylkServer video conferencing application.

Sylk is built using HTML and JavaScript and uses the SylkRTC API to talk to SylkServer. It can be served as a web page using the web server of your choice, or it can be packaged as a stand alone desktop application using Electron. This repository contains the code to build the website and a companion Electron app.

Features

Audio / video calling with SIP interoperability
Multi-party video conferencing (WebRTC only)
Guest mode (no account required if invited)

Customization

The default settings of the app are found in src/app/config.js

    ./configure

For Windows build:

    brew cask install xquartz
    brew install wine

Website

Build the ready to be deployed distribution (available in dist/)

    make

Development build, starts a test webserver which auto-reloads as the code changes

    make watch

Deploy the built website to the server

    make deploy

Deploy the built website to the staging server

    make deploy-test

Electron application

The version number is set in app/package.json

Build the Electron application

    make electron

Build and run Electron application:

    make app-run

Build macOS DMG package

    make pkg-osx

Build Windows NSIS based installer (universal: 32 and 64 bits)

    make pkg-win

NOTE: If building on macOS Wine must be installed with brew install wine.

Build Linux AppImage (both 32 and 64 bit builds)

    make pkg-linux

NOTE: Requires a GNU/Linux system with the following packages installed: icnsutils, graphicsmagick

Common

Clean the distribution

    make clean

Clean all installed packages and generated files

    make distclean

Debugging

By default Sylk doesn't output a lot of information to the browser's JavaScript console. Console debug messages are namespaced by library, the two most important ones being 'sylkrtc' and 'blinkrtc'. In order to enable debugging for both open the browser's JavaScript console and type the following:

    window.blinkDebugger.enable('sylkrtc*,blinkrtc*');

Then reload the page. Debug messages will be logged to the console now.
