Open WebRTC Toolkit Native SDK

Introduction

The Open WebRTC Toolkit client SDK for native Windows/Linux/Android/iOS applications is built upon the W3C WebRTC standard to accelerate the development of real time communication applications on these platforms. It supports peer to peer and conference mode communication working with Open Media Stream MCU server.

• Supported Windows platform: Windows 7 and above.
• Supported Linux platform: Ubuntu 16.04.
• Supported iOS platform: iOS 9.0 and above.

Documentation

To generate the API document, go to the scripts directory, and run python build-win.py --docs for Windows or ./gendoc.sh in talk/owt/docs/ios for iOS.

You need Doxygen in your path.

How to build

Prepare the development environment

Before you start, make sure you have the following prerequisites installed/built:

• WebRTC stack build dependencies.
• OpenSSL 1.1.0l or higher.

The following dependencies are for Windows only:

• Boost 1.67.0 or higher.
• Intel Media SDK for Windows, version 2018 R1 or higher.

Get the code

• Make sure you clone the source code to a directory named src.
• Create a file named .gclient in the directory above the src dir, with these contents:

solutions = [ 
  {  
     "managed": False,  
     "name": "src",  
     "url": "https://github.com/open-webrtc-toolkit/owt-client-native.git",  
     "custom_deps": {},  
     "deps_file": "DEPS",  
     "safesync_url": "",  
  },  
]  
target_os = []  

Build

Windows

• Set the environment variable BOOST_ROOT to your boost source tree.
• Run gclient sync. It may take a long time to download a large amount of data.
• Go to the src/scripts directory, and run: python build-win.py --gn_gen --sdk --tests --ssl_root /path/to/ssl --msdk_root /path/to/msdk --output_path /path/to/out. The built binary will be under output_path, the document for sdk will also be copied to this directory if docs have been generated. If output_path is not set, the built binary will be under src/out directory. Note the first time you run this it will take a long time to pull chromium/webrtc dependencies and require network access to Google's code/storage infrastructure. Set ssl_root to the directory of your OpenSSL 1.1.0 binary. Set msdk_root to the directory of your Intel Media SDK for Windows, version 2018 R1 or higher. Use --gn_gen to generate args.gn during the first build or when you change the msdk_root or ssl_root paths.

Linux

• Run gclient sync. It may take a long time to download a large amount of data.
• Go to the src/scripts directory, and run: python build_linux.py --gn_gen --sdk --tests --ssl_root /path/to/ssl --output_path /path/to/out. The built binary will be under output_path, the document for sdk will also be copied to this directory if docs have been generated. If output_path is not set, the built binary will be under the src/out directory. Note the first time you run this it will take a long time to pull chromium/webrtc dependencies and require network access to Google's code/storage infrastructure. Set ssl_root to the directory of your OpenSSL 1.1.0 binary. Use --gn_gen to generate args.gn during the first build or when you change the ssl_root path. If --msdk_root is specified to correct Intel MediaSDK path, for example, '/opt/intel/mediasdk', hardware codecs will be built besides the software implementations. If --fake_audio is specified, the internal audio devices implementation based on alsa or pulseaudio will not be built.

iOS

• Run gclient sync. It may take a long time to download a large amount of data.
• Build OWT iOS SDK with scripts\build.py.

Android

• Replace the last line of .gclient with target_os=["android"]
• Run gclient sync. It may take a long time to download large amount of data.
• Build libwebrtc for OWT Android SDK with scripts/build_android.py.
