gst-plugins-bad1.0: Hints to achieve a timeedgedetect

[Xavier]

Hi,

I'm pretty new at working with gstreamer. I would like to achieve a 
timeedgedetect plugin, which would detect edges based on differences 
between successive time frames.
I  thought starting from edgedetect plugin, but for now, I'm not able to 
load several time frames so that I can perform the processing. Any idea ?

Thank you for helping
Cheers,
Xavier
