You can subclass GstRtspMediaFactory and implement the
::create_element() virtual method, but I'm not sure if that's needed to
use decodebin here. parse_launch should handle decodebin's dynamic pads
automatically already, just like in gst-launch-1.0, so if that doesn't
work for you then maybe something is missing to make it link decodebin
to x264enc, perhaps a videoconvert element or such?
