I want to build video/audio chat application for my one of the social apps.I开发者_开发知识库s there any library are available in java or ruby or node.js that can help us to build audio/video chat application.

Or any suggestion/technical article that help us to build video chat application.

The xmpp protocol is a good start. There are a lot of implementations for servers where some support video conferencing. There is a lot of support for various languages including ruby, java and even a basic implementation for node(http://github.com/astro/node-xmpp) if thats your thing.
