there should be an example on how to do motiontracking somewhere in the 
examples-directory (examples/04.video/03)

caveats:
the [pix_movement] is an under-optimal movement-detector (only takes 2 
frames into account), i have an improved version lingering on one of my 
machines...

[pix_blob] does not take into account, that some image-sources flip the 
image, so the Y-axis might be reversed


anyhow, it works quite well (for a blob-detector i mean)
