Do you really need all that? What about:

    pipeline = gst.parse_launch(
        "rtspsrc name=src location=rtsp://some.server/url ! "
        "decodebin ! "
        "xvimagesink")

Then if you need to manipulate any of the elements:

    pipeline.get_by_name("src")

etc.

(This is with the 0.10 python bindings; I don't know the python api for
1.0).
