Without the "gst-launch-1.0 " part at the beginning, yes. Why do you
use sync=false btw?

Also you can do
  udpsrc port=5001 caps="application/x-rtp..." ! rtpjitterbuffer ! ...
instead of the separate element.

Note however that your RTP caps are incomplete, more fields are
needed. Check the caps on the sinkpad template in
  gst-inspect-1.0 rtph264depay

Take a look at this example
  https://cgit.freedesktop.org/gstreamer/gst-plugins-good/tree/tests/examples/rtp/client-PCMA.c#n150

It's also noticeable more efficient :)
