Is this a problem of the internal camera or ... what is this ?
Code:
gst-launch-0.10 v4l2src device=/dev/video1 ! video/x-raw-yuv,width=640,height=480,framerate=30/1 ! ffmpegcolorspace ! videoflip method=4 ! autovideosink

Same problem as always, daperl:
...could not negotiate formate.... check your filtered caps, if any....
As soon as you try to tidy up the output of the camera, it gorks.
EDIT: Setting it to ... ! video/x-raw-yuv,width=640 ! ... works, but it looks exactly the same.

Ok this isn't stretched anymore, but it still has the dark band:
gst-launch-0.10 v4l2src device=/dev/video1 ! "video/x-raw-yuv,pixel-aspect-ratio=(fraction)1/1" ! ffmpegcolorspace ! videoflip method=4 ! xvimagesink force-aspect-ratio=true
gst-launch-0.10 v4l2src device=/dev/video1 ! "video/x-raw-yuv,pixel-aspect-ratio=(fraction)1/1" ! ffmpegcolorspace ! videoflip method=4 ! xvimagesink force-aspect-ratio=true

The dark band problem is deeper, either electronics or kernel driver level. It's there even I don't use gstreamer at all (=direct v4l2)

But if you have a small mirror with you, you can position it so that you can see the N900 screen.

just an observation.
you want to use a small mirror in your possession to hack together an app supposed to work as a mirror?
isn't that a little redundant ?

In case some devs wants to track progress or make their own packages, I opened a garage project for this 'app' (talk about waste of resources 
). The address is https://garage.maemo.org/projects/mirrorapp/

The solution is simple though, use TWO N900s and display the main cam image on the OTHER unit. Now THAT is a PUSH project right there

Ok, so here's how to get rid of the dark band. Use "videocrop" to crop it away!
The new pipeline to produce a properly sized image with no dark band:
gst-launch-0.10 v4l2src device=/dev/video1 ! "video/x-raw-yuv,pixel-aspect-ratio=(fraction)1/1" ! ffmpegcolorspace ! videoflip method=4 ! videocrop right=122 ! xvimagesink force-aspect-ratio=true
