Hi Franz,
You should be able to use any plugin from gstreamermm. Please have a look
at the examples in the gstreamermm repository, for example the oggplayer
[1]. As you can see there, we create filesrc element using ElementFactory
class, which returns an object of type Gst::Element:
Glib::RefPtr<Gst::Element> source = Gst::ElementFactory::create_element(
"filesrc");
This object has bunch of methods, and the one you might be interested in is
set_property which is equivalent to g_object_set and allows you setting
property values, e.g.
source->set_property("location", "/my/file.mp4");
Please let me know if you have any questions
