GStreamer is a streaming media framework, based on graphs of filters which operate on media data. Applications using this library can do anything from real-time sound processing to playing videos, and just about anything else media-related. Its plugin-based architecture means that new data types or processing capabilities can be added simply by installing new plug-ins.

This package contains the GStreamer plugins for X11 video output, both for standard Xlib support and for the Xv extension, as well as the plugin for Pango-based text rendering and overlay.
