Would you try this (just adapt to your camera resolution). Works fine for me:

# Signal handler for stopping pipeline before destruction, so that Argus keeps ok.
def signal_handler(sig, frame):
p.set_state(Gst.State.NULL)
sys.exit(0)
# Initialize gstreamer
GObject.threads_init()
Gst.init(None)
# Define pipeline

For EOS management, you may also try this:
