Bonsoir, Jean-françois:

je reviens sur gspcav2 cette fois avec la nouvelle version gspcav2-0.0.25,

  # rmmod gspca
  # cd /usr/src/modules/gspcav1-20071224/
  # make uninstall
  # copie de gspcav2-0.0.25.tar.gz dans /usr/src/modules/
  # cd /usr/src/modules/
  # tar xzvf gspcav2-0.0.25.tar.gz
  # cd gspcav2-0.0.25/
  # make -f Makefile.standalone
  # cp *.ko /lib/modules/2.6.18-6-686/kernel/drivers/usb/media/
  # depmod -ae
  # modprobe videodev

  reboot

  # modprobe gspca_zc3xx
  # modprobe gspca_main

  # luvcview -d /dev/video0
luvcview version 0.2.1
Video driver: x11
A window manager is available
video /dev/video0
----> ecran noir , xkill pour fermer luvcview
