We needed something similar, and I ended
up using Lego NXT sensors, and wrote a gstlego element.
The idea is that you emit a light at time0
into a camera, and then you use another sensor to sense the light at time1 on
the screen. The accuracy was about +/- 2ms, so if you can live with that, I recommend
this approach, since it is both cheap and fun! J

Subject: [gst-devel] How to
measure the delay with GStreamer?
I
was working on a video conferencing project, and want to get the exact delay
form when it was grabbed through the 1394 firewire to being displayed on the
screen of another PC in LAN.
Any
clue about how to implement this?
