Dear Ángel, I've tried gstreamer jp4 - it worked on Kubuntu 9.10. And at the beginning I was having an error "gst ERROR: pipeline could not be constructed: no element "rtspsrc" ".
1. The error gone after I installed "gnome-media". 2. Then I had to install some gstreamer dev libraries and gst-plugins-elphel: http://code.google.com/p/gst-plugins-elphel/wiki/HowToInstall. What's your output of "*gst-inspect bayer2rgb2 * gst-inspect jp462bayer"?
