A-ha! There is a macros GST_ELEMENT_PARENT(). If you have a decoder element,
then, some bin will be its parent, and you can get it.
However, I'm in doubts about correctness of your approach. In my
understanding, the 'transforming' element just gets data from outside and
processes them. It should not deal with the sources of that data.
What if the data would come from a live stream, or would be
application-generated, such that the file descriptor simply doesn't exist?
