Library selection for using WebRTC for the project.
Selecting a good and resilient library with frequent updates is imperative, these are the libraries available:
Google's official library that we have to compile to use in our project: http://webrtc.github.io/webrtc-org/native-code/android/
Ant Server's library: https://github.com/ant-media/Ant-Media-Server/wiki/WebRTC-Android-SDK-Documentation - Here they used "Ant Media Server" as signaling server we can change that.
Ant Media Server uses WebRTC library on top of that they added their own functionality to make it work with Ant Media Server. Which is not very useful for our project.
