[SECURITY] Fedora 26 Update: gstreamer1-plugins-good-1.12.0-1.fc26

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 plugins. GStreamer Good Plugins is a collection of well-supported plugins of good quality and under the LGPL license.
