Hi

I made some test with both master and 1.4.1,
In these two version, I can see a thin green bar, 1 or 2px height, at the top
of the picture with the following shortened pipeline:
gst-launch-1.0 filesrc location=<file> ! qtdemux ! h264parse ! avdec_h264 !
videoconvert ! xvimagesink

I notice this top bar disappears when I maximise the window, instead I have a
bar at the right side.

Encoding the resulting pictures in png instead of rendering them, I notice that
the dump doesn't have green bar.

I also run some test on my working board which have gst 1.4.3 version.
I tested with both a v4l2sink and a fbdevsink and I see no green bar. However
video is downscaled to 800 pixel height, so the green bar might not be really
visible.

So I think xvimagesink may be a good start point.
