The "GStreamer SDK" tutorials, at least, seem to recommend using
"gst_parse_launch"[1]:

    Please note that gst-launch is primarily a debugging tool for
    developers. You should not build applications on top of it. Instead,
    use the gst_parse_launch() function of the GStreamer API as an easy
    way to construct pipelines from pipeline descriptions.

...although they introduce it rather late (in the 10th tutorial, after
using gst_element_factory_make etc in all the previous tutorials).
Subsequent tutorials ([2], [3]) do use "gst_parse_launch".
