Description-en: GObject introspection data for the GStreamer library
This package contains introspection data for the GStreamer streaming media
framework.
.
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.
.
It can be used by packages using the GIRepository format to generate
dynamic bindings.
