Use Debian 8, and use our packages for the dependencies, there is a page on the wiki for how to install like this

hank you,

i have downloaded linphone, the latest version support only VP8 (probably i need manually download codec and recompile it for h264)

I have tried a previous version, 3.7.0 that support h263 and H263plus, the softphone work correcly but the freeswitch dont seem to inizialize this codec:

a=rtpmap:34 H263/90000
2015-11-02 10:22:40.128555 [INFO] avcodec.c:1040 initializing encoder 704x576
2015-11-02 10:22:40.128555 [ERR] avcodec.c:909 Could not open codec

i have donwloaded the dependences from
https://freeswitch.org/stash/scm/sd/libav.git

reconfigure recompile and install it, recompile the mod_av, bt always got this error..

In this debian fresh install seems h263 and H263P are not correcly inizialized.

Any clue about this?

is a very strange issue      Da: Giovanni Maruzzelli <gmaruzz at gmail.com>

Ciao Emiliano,

for testing high resolution video on SIP you can use linphone, is opensource and available on all platforms.

http://www.linphone.org/downloads-for-desktop.html

Let us know how you progress, and your findings.

thanks you, many manythanks you saved my life, recompiled all and all do what i expect it does.
One problem not relater to freeswtich was the softphone i use for testing, in the decode part of OpenH264 or mod_av (c code) i have printed the resolution of frame sent by softphone.
X-lite (only h263), Jitsi (max frame sended in h264 was 1280x720), Lifesize (H264 352x288) i don't have found a solid sofphone for testing my freeswitch whiout web rtc in HD (1980x1080) do you know anyone?thanks you for all you have done a great job and productEmiliano OlivierItaly, Rome

You are choosing to work on a platform we have not tested.You should try to build on debian 8 jessie with our repo for depends with detailed instructions we have put out there after spending a year on this project.The libraries used in video are all over the place in various distros so you can either painstakingly try to check all the versions of each one we use or reproduce your problem according to our specifications at https://freeswitch.org/confluence/display/FREESWITCH/FreeSWITCH+1.6+Video Otherwise the possibility that your problem is system related will always loom.

I saw a video bandwidth cap config in vars.xml somewhere. Maybe that's set a bit too low? Just a random guess.
