[Freeswitch-users] Enable H264 Video

[Jürgen Wendler]

Hello everyone,

i've found some amazaing articles about FS and so i thought i can give it a try.
So I followed instructions in confluenca and got a simple running fs server with mod_verto which is capable of some basic webrtc. Really nice.

Now I want to join this room (which is the basic 3500 room with the default video-mcu-profile) with some external h323 device. So I compiled ptlib and opalvoip and finally mod_opal and created a h323 listener.
When I call the ip + room number with an external device (polycom, sony) via h323 I get voice only connections, log says the following:

2016-09-12 12:26:17.140849 [WARNING] mod_opal.cpp:750 {Opal Answer:12170,0000000000001} mod_opal        Could not match FS codec H263-2000 at 90000 (pt=121) to an OPAL media format.

So I thought I should have a look about the compiled codecs. I activated mod_opal and mod_h26x in modules.conf but no succes. Log always says:

2016-09-12 12:26:17.160836 [INFO] h323.cxx:3996 {Opal Answer:12170,0000000000001} H323          SetLocalCapabilities: GSM-AMR,G.723.1,G.729,GSM-06.10,G.711-uLaw-64k,G.711-ALaw-64k,T.38,UserInput/hookflash,UserInput/basicString,UserInput/dtmf

I've tried to change profile or the conference / dialplan, event set "absolute_codec_string" in dialplan/default.xml but I think I am missing something.
Could anyone point me in the right direction where I can "enable" h263++ or h264 video capabilitys for an external h323 device / call via mod_opal?
System is debian 8, FS and ptlib / mod_opal are checked out from git / cvs.

Best regards,
Juergen
