GStreamer is a streaming media framework based on graphs of filters
that 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 plug-in-based architecture
means that new data types or processing capabilities can be added
simply by installing new plug-ins.

This package contains well-written plug-ins that can't be shipped in
openSUSE because of patent problems.
