Both (libv4l-0 version 0.5.8-1 and libv4l-dev version 0.5.8-1) have  
been installed with synaptic.
I try apt-get install libv4l-dev, but i get a confirmation that i  
have the most recent version.
I don't know if that can help you to understand but the pidip object  
[pdp_v4l2] works fine here.

No, i don't want :)
But if it is the only one solution, i will try it.
Any Idea ?
