gstreamer-tools binary package in Ubuntu Trusty amd64

 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 unversioned command-line tools for GStreamer
 that work with different major/minor versions of GStreamer.
