Re: [Linphone-developers] how can i add other codecs to linphone windows version 3.10.2 ?

[Sandrine]

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:

error: 2016-09-07 11:14:22:770 QOSAddSocketToFlow failed to add a flow with error 87 appears several times.
What does that mean ? Is it severe ?


Is the following interesting ?

What is "frozen list" ?

appears often. Video d (downstream ?) is mostly between 60 - 70 (Kbit/s ?).
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.
