Can you try the following two commands:
1. gst-launch videotestsrc ! ximagesink

It shows several coloured vertical lines.  The output is:
snoopy:~$ gst-launch-1.0 videotestsrc ! ximagesink
Setting pipeline to PAUSED ...
Pipeline is PREROLLING ...

So it doesn't look at all like the first window shot in this page: http://wiki.oz9aec.net/index.php/Gstreamer_cheat_sheet
? Only the lower right corner should move.

2. gst-launch videotestsrc ! agingtv ! ximagesink

The same erroneous window, with the same output.

It should be only slightly the same, with an aging special effect so the streams can be discerned apart (as I write "apart" I wonder if it shouldn't have been "one another" or something like this...).

Could you explain what is the ekiga architecture for video?  We have
clutter thing, v4l2 plugin thing, X code thing in ekiga, now you propose
gstreamer thing... how are they related?  What precisely will gstreamer
code replace?

Gstreamer should replace mostly everything... connecting on one hand to
opal for the network part and to Damien's clutter code for the video

So will it replace all ptlib plugins?  Currently there is:

Yes. And the same code should work regardless of the platform.
