gstreamer1.0-plugins-ugly binary package in Ubuntu Focal s390x

 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 plugins from the "ugly" set, a set of
 good-quality plug-ins that might pose distribution problems.
