The desired output is the desktop image. What we see instead is a black screen 
and the mouse pointer.

What version of the product are you using? On what operating system?

Ardesia is a screen sketcher that helps when you want to stream your desktop, 
then you want to draw on top of it.

Sorry i am using Ubuntu 11.04 X86 and compiz as composite manager.

It seems like gstreamer can not see behind ardesia transparency channel. I have 
tested capturing with vlc and it works fine. Maybe the whole issue is how 
gstreamer handles the capture.

CU guys, you really make life good.

I remember those issue with GStreamer and composite.  I'm currently moving away 
from GStreamer to FFMPEG...

Until the new 0.60, you can use a pipeline to create your own screen capture 
source to avoid this issue with composite
