It depends what you want to do exactly, if you want to sub-class GstBin
and register your own element with the GStreamer registry, or if you
just want to create a convenience bin as an abstraction layer in your
application.

For the former you could look at the autodetect plugin in -good.

For the latter, gst_bin_parse_from_description() is the easiest way,
otherwise just create a new bin with gst_bin_new(), add elements to it,
link them, and then add ghostpad(s).
