Package: gst-plugins-bad1.0 Version: 1.6.1-1 http://gstreamer.freedesktop.org/data/doc/gstreamer/head/pwg/html/section-boiler-project-stamp.html states that "for creating elements the tool gst-element-maker from gst-plugins-bad is recommended these days".
Today it seems it only appears in the source package, it would look like a good idea to ship it as part of the -dev package.
