Barōk (barok, from baroque) is a media player daemon, it plays your music or video as a background process. It can be controlled by compatible (graphical or not) front-ends but doesn't constantly need one, thus saving resources. Plus, Barok aims to be lightweight and also easy to use.
It can be compared to MPD (Music Player Daemon) but it supports audio, video and live streams, it uses Gstreamer for playback and d-bus for communications. It doesn't aim to support remote control over a network like MPD (so it is more secure), but instead, it can be controlled easily through SSH, telnet, or sockets, or related transports using console clients and d-bus.
