Hi Ghislain,

thanks for your help. I am currently trying to set up a build environment. Once 
I succeed, I will report.

Thanks again,

Moritz

Betreff: Re: [Linphone-users] Python Wrapper on Raspberry Pi 2: Critical 
errorwith display video enabled

Hi Moritz,

Indeed, as the log is saying no display filter is available. This is because 
the linphone for raspberry packages we provide are built without video support 
so that it can run on raspberry PI with no x11 stack installed (that is 
probably the most common case).
If you wish to have video display you will need to build it yourself following 
the instructions on the wiki. Just make sure the x11 and xv libraries and 
headers are available in your rootfs before building linphone.

Cheers,
Ghislain

Hi, 
 
I found this error has been reported already twice 
(https://lists.gnu.org/archive/html/linphone-developers/2015-06/msg00093.html 
and https://lists.gnu.org/archive/html/linphone-users/2015-04/msg00015.html) 
but unfortunately, no solution has been provided yet.
 
I started with the example code provided here: 
https://wiki.linphone.org/wiki/index.php/Raspberrypi:start
 
I just changed the line 
self.core.video_display_enabled = False
to
self.core.video_display_enabled = True
 
The code crashes with the following line after the caller tries to start a 
video connection.
 
INFO:root:Using WebM Project VP8 Decoder v1.4.0
ERROR:root:no such method on filter MSVp8Dec, fid=16389 method index=7
CRITICAL:root:No video display filter could be instantiated. Please check 
build-time configuration
 
I am running on clean raspbian installation on a Raspberry Pi 2 model B.
 
Any help would be appreciated.
 
Kind regards,
 
Moritz
