Description:
GObject introspection data for the GStreamer Plugins Base library
This package contains introspection data for the GStreamer Plugins Base library. . 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.
