Thank you very much Sebastian.

Thanks to Flavio, fix the problem. The problem was with the resolution,
(witdth = (int) 1920, height = (int) 1088, or divided by 2 or 4).

I work with the binary http://code.google.com/p/gst-plugins-elphel/ and
with which I compiled (debian wheezy (arch:x86_86) & gstreamer v.0.10.36).

It's amazing the flow on JP4.
