Hangouts runs on a Google proprietary protocol. They are depreciating their foss Jingle library for xmpp video and audio conferencing for Hangouts, to force people to use their entire stack to use Hangouts. I'm hoping Daala + Opus conferencing and streaming can enter Jingle in the next few years, see it mainlined in jabber, and that could be a good alternative. Self-host your own xmpp server if you want, or use a web service that provides it (like Talk did).
