Hi,
Thanks
The video is a very good idea.
Unfortunately i obtain this error message :
--------------
controls
VIDIOC_QUERYCTRL (9963776)
break
--------------
With gspca on 2.6.27 kernel
and without gspca on 2.6.24 kernel
(Ubuntu Hardy 32 bits)
An idea ?
With vlc 9.0 my webcam works fine (with and without gspca), there is
v4l2control panel where i can set exposure, gain, red balance and blue
balance
Regards
Laurent
