# WebRTC C++ sample
|
||||||
|
Sample program for using WebRTC(DataChannel) on C++.
|
||||||
|
|
||||||
|
# Requirement
|
||||||
|
|
||||||
|
* Mac OSX
|
||||||
|
* Please download libwebrtc(It is precompiled chrome's WebRTC) and unarchive it.(https://github.com/llamerada-jp/libwebrtc)
|
||||||
|
|
||||||
|
# Compile
|
||||||
|
|
||||||
|
```sh
|
||||||
|
$ cd <path to work>
|
||||||
|
$ git clone --depth 1 https://github.com/llamerada-jp/webrtc-cpp-sample.git
|
||||||
|
$ cd webrtc-cpp-sample
|
||||||
|
$ git submodule init
|
||||||
|
$ git submodule update
|
||||||
|
$ cmake -DLIBWEBRTC_PATH=<path to unarchived webrtc> .
|
||||||
|
$ make
|
||||||
|
```
|
||||||
|
|
||||||
|
# Run
|
||||||
|
|
||||||
|
This sample use two consoles to try interprocess communication by WebRTC.
|
||||||
|
It maybe cannot communicate over NAT each other, because it does not use ICE server.
|
||||||
|
|
||||||
|
## Connection
|
||||||
|
|
||||||
|
memo : On this sample, Some commands requireing parameter need line of only a semicolon after parameter.
|
||||||
|
|
||||||
|
At CONSOLE-1.
