gstreamer1.0-plugins-base-dbg binary package in Ubuntu Xenial i386

Xenial (16.04)
i386
gstreamer1.0-plugins-base-dbg

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 unstripped shared libraries. It is provided primarily
to provide a backtrace with names in a debugger, this makes it somewhat
easier to interpret core dumps. The libraries are installed in
/usr/lib/debug and are automatically used by gdb.
