Yes, I used your suggestion before, but now using a pipeline-like
description is mandatory. I need to connect a described bin to one
custom element (experimental, wroten in Python elements)

On that way I need to have access to the last element of the bin. My
problem with that (and then, for use gst_bin_get_by_name) is I don't
know the element name (maybe pre-processing the bin description
string?).

My target is to get a program that reads a description of a Bin from
the command-line argument and then link, at the end of the bin, another
element.

Regards and thanks for your answer, it was very helpful!
