[Ekiga-list] Philips SPC620NC, Video garbled

[Nikolaus Rath <Nikolaus rath org>]

Hello,

I am using a Philips SPC620NC webcam using the v4l2 driver. Ekiga
version is 2.0.12 (from Ubuntu Hardy). Ekiga's configuration druid
successfully performs all the tests. I can also access the webcam
sucessfully using e.g. mplayer and luvcview (example screenshot:

In ekiga however, the video display is mangled. It is solely in green
and has horizontal stripes all over. I have uploaded a screenshot to
http://launchpadlibrarian.net/15698333/Screenshot-Ekiga.png

I have also enquired on the linux-uvc driver list about this issue. I
was told that such a phenomenon might happen if ekiga receives yuv
data but interprets it as png.

Interestingly enough, luvcview tells me that my camera only sends in
yuv:

# luvcview -f jpg
luvcview version 0.2.1 
Video driver: x11
A window manager is available
video /dev/video0 
Unable to set format: 22.
 Init v4L2 failed !! exit fatal 

and directly terminates.

nokile:~/projekte/s3fs$ luvcview -f yuv
luvcview version 0.2.1 
Video driver: x11
A window manager is available
video /dev/video0

shows the picture nicely.


However, I also heard that other people with webcams who deliver only
yuv are running ekiga nicely, so I suppose it is not a principal
problem.


Does someone have an idea how I can fix this problem? Is there an
option to force ekiga to use the yuv format or something like that?


Thanks in advance!


Best,

 
   -Nikolaus
