## Description

BaconVideoWidget is a widget to play audio or video streams, with support for visualisations for audio-only streams. It has a GStreamer backend, and abstracts away the differences to provide a simple interface to the functionality required by Totem. It handles all the low-level audio and video work for Totem (or passes the work off to the backend).
