[Linphone-users] empty video output

Hi,

I hope someone can help me to get "moving pictures"!

I have successfully compiled Linphone 2.1.1 on open Suse 10.2 (at least
I think I have).

Now I try to make linphone work mit my genius "look 316" webcam.

With the v4l-driver, I can use this webcam either with
> gqcam
or with
> xawtv -nodga -noxv -device /dev/video
It works fine with ekiga too.

But if if i start linphone, the log first looks promising, but then I
only get a plain, green screen - I'd say: no signal arrives from the
camera. (But the led of the cam swiches on, and off again when linphone
is finished, so there is some communication.)

All this happenes before making any call - i suspect normally I should
see the output of my own webcam when I am not connected with someone else.

Calling an echo-service, after the connection is built, the log gives
lines like:
"ortp-message-bandwidth usage:audio=[d=85.3,u=85.3]video=[d=0.0,u=0.0]
kbit/sec"
and the video-screen stays blank. I give the log later in this mail.

I tried some permutations of the list of video-codecs (H263-1998,
MP4V-ES, theora, x-snos) - they all seem to be available (written in
blue, not red), this didn't help.

Might it be a problem with the Nvidea-driver (the option -nodga in the
above xawtv-command is due to this)?

Maybe its something very, very simple, but I have no Idea at the moment.
I have not testet, wether incomming video-signals are shown, I lack on
working test-numbers. Most of the numbers of
"http://wiki.ekiga.org/index.php/Fun_Numbers"; dont work - maybe because
I dont enter them the right way, but that is a different issue, I guess,
the video-problem isn't "out there".

Greetings,
  Detelf

Here is the log of this session: I start linphone, call
sip:address@hidden, make a short noise, hang up again and leave
linphone.
