How to get pipeline from gstreamer plugin written in python?

[Michael Gruner]

Ultimately, you need the pipeline (or a bin) to get the element by name. Elements live in bins, which are their parents. The only element that doesn’t have a parent is the top level pipeline. Something like this should work:

parent = your_element;

do {
  old_parent = parent;
  parent = gst_object_get_parent (parent);
} while (parent);

pipeline = old_parent;

other_element = gst_bin_get_by_name (pipeline, “name”);

Hope this helps,
