NDN WebRTC Conferencing Project

For license information see LICENSE.

http:https://named-data.net/

Early stages of an NDN-based videoconferencing tool based on the WebRTC implementation in Firefox.

App code is divided into to main parts - C++ code of add-on and Javascript code of web app. C++ code provides all basic operations for establishing NDN-connections to other peers and transmitting/receiving encoded media. It also exposes it's interface to the web-page Javascript through Javascript wrapper object attached to DOM's window object of a page.

Javascript code of web app provides all th UI and peer discovery/authentication logic of the NDN-RTC application.

The directory structure is as follows:

• /root
  • ccp/ -- c++ code
    • addon/ -- Firefox-specific files for add-on installation
      • components/ -- Javascript wrapper code
    • bin/ -- compiled files, dynamic library of c++ add-on, .xpt component interface file for Firefox
      • ndnrtc/ -- upacked add-on
      • ndnrtc.xpi -- compiled add-on package
    • content/ -- add-on resources and helper Javascript files
    • idl/ -- add-on's idl interface files
    • src/ -- .h and .cpp files of c++ component
  • html/ -- web app directory
    • js/ -- Javascript for web app
    • index.html -- main page for web app
  • LICENSE
  • README.md

1. XULRunner SDK (or Gecko SDK). Check the latest version here. Current code was compiled with SDK version 25.0a1 (Nightly).
2. WebRTC libraries (check http:https://www.webrtc.org/reference/getting-started).
3. Gtests framework (check https://code.google.com/p/googletest/source/checkout).
4. NDN-CPP library (check the latest commit from https://github.com/named-data/ndn-cpp.git).

1. Setup XULSDK environment path:

    $ export XULSDK=~/mozilla/xulrunner/dist

2. Setup PYTHONPATH environment path:

    $ export PYTHONPATH=$(PYTHONPATH):$(XULSDK)/sdk/bin

3. Checkout latest commit of WebRTC into thirdparty directory under ndn-webrtc name and build it for x64 architecture.

4. In order to run tests, checkout Gtests library into thirdparty/ndn-gtest.

5. Initialize git submodules (for NDN-CPP):

    $ git submodule init
    & git submodue update

3. Perform make:

    $ cd cpp
    $ make addon

1. Check bin directory for ndnrtc.xpi file, open it in Firefox and restart.
2. Open html/index.html file.
