Motion detection

[luke]

Hi all,

I would like to use gstreamer through the CLI to store a video when motion is detected but I don't know how to configure the sink to store the images only if a motion is detected. Something like:

gst-launch-1.0 v4l2src ! videoconvert ! motioncells ! ??? 

I don't care about the cells themselves. Actually, I would rather not have them rendered on the stored file.

Any idea how to do this?
