gst_element_get_request_pad() is being replaced by gst_element_request_simple()
since 1.19.1, throwing a warning in case of use until its definitive
replacement on 1.20.
Hence, prefer using gst_element_request_simple() in case gstreamer
version is >= 1.19.1 to avoid the compilation error below (tested on f35):
