Hi,thanks indeed for all the assistance and  link,  after many days of work i manage put all together.

For for further information, Debian packages in master branch (installed as it is) or the compiled code, all present same problems.
I  need to change many part of code in avcodec.c (in open_encoder function of mod_av for h263) in mod_openh264.cpp (FillSpecificParameters for openH264) and still h263+ not work, specifically the bandwidth and other parameter set in mod_conference.c are ignored here (actually i start to inspect switch_core_media.c for some strange behaviour).

My only remaining problem is about cpu usage, a 1080p (full hd) conference with 3 person in trascoding (mux  video mode) make my dual core dual socket virtual machine with 4gb of ram (vm whare)  seem a slow snail. (100% cpu usage and packet loss everywhere).
I'll look forward for any commit and someone that tries the freeswitch in similar behaviour of mine.

Emiliano,
You need to take it much much easier.
It took many years/man to define the building process and dependencies of FreeSWITCH.
Take your time to understand and digest and experiment with it.
If you need immediate results for a custom build, and your company has no time to wait for you to develop it, write to consulting@freeswitch.org for paid professional consulting that will solve any and all problems. Is a trade off between time and money, your company must evaluate what is best for her strategy.

thanks you for all
rebuilded all but i have encountered 2 problem
The source of freeswitch are checked in util.sh and if i do any changes in sources (i have changed few rows in mod_conference) the procedure stop.
After rebuild all packadge trying to install it with dpkg -i (all deb files) takes many error.
and seems that inside the packadget there isn't all the required dependences..
i am a bit desperate working 12 hours every day for H263 and libav :(
thank you for any info provided.

done in a fly

following your guide and Installing from Debian packages in master branch (not recompile) seems all ok and work in h263..
so..i am more unluky..
i want to compile it, i don't find the difference between compiling and downloading the packadge..the problem seem relatet to libav..

read the docs, Luke: https://freeswitch.org/confluence/display/FREESWITCH/Debian+8+Jessie
