+ +A minimal self-hostable streaming setup. + + +## Setup + +`brook` is a modular project, meaning that many different components +come together to provide a simple and relatively lightweight streaming +setup. Following is a quick overview of components. + +* `ffmpeg` - running an rtmp server, and converting video to `dash` + output format +* `nginx` - serves the `dash` directory +* `index.html` - static html file with js for a dash player and xmpp + web chat +* `brook-metrics` - the only custom server-side program to track + viewer metrics +* `prosody` - An XMPP server to back the chat room + diff
