gir1.2-gstreamer-0.10-dbgsym binary package in Ubuntu Xenial i386

 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.
