You can add "sync=false" to the source gst pipeline. On Ubuntu 12.04 that seems to remove the lag and error messages.

Here's the command I used on the source:

gst-launch videotestsrc ! x264enc tune=zerolatency ! rtph264pay ! udpsink host=127.0.0.1 sync=false

and here's what I used on the receiver:

gst-launch udpsrc ! application/x-rtp,payload=96 ! rtph264depay ! decodebin ! xvimagesink

Unfortunately, I have no idea why that works or even which component the "sync=false" property belongs to (on the source pipeline).
