Hi Bernd (that’s ok, no offense taken )
If you have wireshark installed, could you capture and then send us the .pcap logs of a videoconference with linphone and another one with Ekiga so that we have a chance to pinpoint exactly where the problem is?
We’ll see for H263 afterwards.
Best regards,
Sandrine Avakian Software Engineer
Hi Sandrine (omg, all the time i spelled your name wrong. Sorry), that didn't help. I tried all three, udp, tcp and tls. I also created an account and choosed tcp, that didn't help either. What i'd like to do is trying another codec. Like H.263. VP8 is not supported from the other side. How difficult is it to compile another one on windows ? I never did that. Just a few times on linux when installung software from the sources. Do you have a HowTo for that ?

In this case, add "; transport=tcp » at the end of the address you are calling

Hi Sabrina,
thanks for your support. You are doing a good job.
In Options->Preferences->Manage sip accounts i don't find s.th . to switch off
tcp.
See attached screenshot.
I will test the other stuff and let you know.

Hi Bernd,
We think there may be a misunderstanding between linphone and your other
equipment.
There are a few options to try solve this out.
If the other equipment supports TCP, try using TCP as the transport
(Options->Preferences->Manage sip accounts->Edit
set transport to TCP).
If not, disable all the other unused codecs (Options,Preferences->Codecs) :video
:VP8
for audio only keep the one you want to use enabled, disable the others.
We would like you to try out is to explicitly set a bandwidth limit on upload
and download of 1Mbits/s (Options->preferences->multimedia settings->bandwidth).
Get back to us to tell us if it’s better.

Hi Sabrina,
now the log attached.
What i found out:

What does that mean ? Is it severe ?
Is the following interesting ?

That's the problem, isn't it ? What's the reason ?

Hello Bernd,
Did you modify any parameter to control the bandwidth?
Options->preferences->multimedia settings ->Bandwith control
Could you check what is happening in the linphone debug logs when you start a
video call in H264? (Help->debug window)
If unclear, please send the logs to me.
Kind regards,

Hi Sabrina,
thanks for your answer. I'm not used to compiling on windows, so i will not try
it.
My problem is: we need to participate on a vc. I try to establish it with
linphone. The vc system is a Tandberg device. The video stream i get from the
tandberg is just 64Kbit/s, which is of course very rare, so quality is poor. My
video upload to the tandberg is ok.
I try to paste screenshots here: if it's not possible to send this e-Mail i can
offer the screenshots as a download.
<7431126.28>
And a screenshot from the Admin Webconsole of the MCU:
<7518382.55>
You see a rate limit from 64Kbit/s.
Using Ekiga as a client (which i don't want to use, it's not stable) i have a
rate limit of 4.1 Mbit/s. So quality is much better.
Anything i can do on that ?
Thanks.
Bernd

Hello,
Due to patents issues, H263 is indeed not included in the release.
To have H263 in linphone-desktop, a new build from source has to be made with a
few specific compilation options:
-DENABLE_FFMPEG -DENABLE_NON_FREE_CODECS -DENABLE_H263.
We believe H264 is still a better alternative though.

Hi,
i'm using linphone 3.10.2 on windows 7 64bit. As video codecs, i just get
offered h.264 and vp8. Is there a possibility to use more codecs ? Like H263
... ?
Thanks.
