Cheese doesn't work also :-(
Comment 4 Jean-Francois Moine 2008-10-26 12:28:06 UTC 
The driver gspca v2 does not work without the v4l library.

Please, have a look at my page:
   http://moinejf.free.fr
and read carefully the gspca README (gspca_README.txt).
Comment 5 Pacho Ramos 2008-10-26 12:38:03 UTC 
You are true, sorry for the inconvenience, now it works ok with:
LD_PRELOAD=/usr/lib64/libv4l/v4l2convert.so cheese

Thanks a lot
