Hi Daiane

The plugins were been used with linux-boundary. As I said to Lauren we 
did a repo sync and now the sink is included in the dylan branch. Next 
week we see how it works.

Oh! I am shocked .. . again :) I thought linux-fslc was the kernel used 
by Freescale TLIB people. I cand find many posts where they are working 
with gstreamer.  As you can see, I am very lost in this labyrinthic 
forest full of roots, trees and branches :)

Thank you again
