libgstreamer-plugins-base1.0-0 1.16.3-0ubuntu1.2 (amd64 binary) in ubuntu focal

 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 libraries from the "base" set, an essential
 exemplary set of elements.
