Hello to everybody on this list,
my system is Debian etch i686, the camera is a Philips SPC620NC. I built
the uvcvideo.ko module from the Linux UVC SVN trunk. luvcview works
without problems with the camera and video quality is good.
I tried with these Debian packages from etch-backports: Ekiga 2.0.11,
Opal 2.2.11, PTlib 1.10.10. The problem also exists with Ekiga 2.0.12
built from the source tar archive.
The video is not usable, because it has a green colouring and horizontal
and vertical stripes. Apart from the green colouring and stripes,
apparently the video is alright and Ekiga runs stably. In the video
settings i can adjust brightness, whiteness, color, and contrast, which
each has effect on the video.
The video test in the configuration druid gives this error message:
Failed to open the device
Could not open the chosen channel with the chosen video format.
I tried to build Ekiga from the SVN trunk, but ./autogen.sh led to an
error, GTK 2.10.0 is required, but 2.8.20 is in etch.
Before continuing my efforts, I would like to ask if there is a chance
that building Ekiga, Opal and PTlib from the SVN trunks will solve this
issue.
A green video problem is also reported in this message, it is a
different camera but it uses the Linux UVC driver too:

Thank you and best regards,
