When I use this command:

gst-launch ximagesrc ! video/x-raw-rgb,framerate=5/1 ! ffmpegcolorspace ! theoraenc !        oggmux ! filesink location=desktop.ogg

ximagesrc usage

It shows me only desktop screenshot and video length is 0:00 or sometimes it just shows pictures without mouse motion.

More information: Ubuntu 10.04.3 this is a text

You can try something like this:

gst-launch ximagesrc use-damage=0 ! video/x-raw-rgb,framerate=15/1 ! ffmpegcolorspace ! x264enc ! matroskamux ! filesink location="test.mkv"

Perhaps just the use-damage=0 parameter to ximagesrc will help.
