I was wondering how live streaming or chat video works? I know a bit about PHP and I've been learning ajax and jquery. I was wondering if it is possible to build such a system using PHP? Or maybe HTML5? I'm not too familiar with HTML5 but if that could be a possibility, I would definitely learn it.
Can someone help me get my feet going?
Thanks!
For HTML5, you're looking for WebRTC. See http://www.webrtc.org/. This spec enables live streaming (video/audio) from within a browser.
Still, you need a backend to process the streams and connect people together. This is not very well suited for PHP, and I'd rather use Node.js, a server that enables very lightweight 'two-way connections' to clients. See http://nodejs.org/.
