Sure, the most common methods of app -> element communication are:

1. g_object_{set|get}

2. g_signal_emit_by_name() (ie. action properties)

3. make the element implement an interface (see e.g. GstUriHandler or
GstXOverlay)

4. you can gst_element_send_event (element/pipeline, ...) a custom
event.

5. if the element/plugin is a static plugin and not an installed .so you
can just add API for it and use that.
