[Freeswitch-users] Freeswitch basic VP8 passthrough

[Adam Ben-Ayoun]

Hi guys,

I am trying to setup a simple WebRTC video conference using VP8 with
mod_conference, while audio conferencing works fine, I am not able to setup
a video conference using clients like SIPjs, basically, I am opening 2
clients and expect to see video streaming to each side.

I did the following:
1. Added the following config to my conference profile in
conference.conf.xml:
<param name="conference-flags" value="video-bridge"/>
<param name="member-flags" value="video-bridge"/>

2. Added VP8 to vars.xml:
<X-PRE-PROCESS cmd="set" data="global_codec_prefs=iSAC at 16000h
,VP8,OPUS,G722,PCMU,PCMA,GSM"/>

Any idea?

P.S The client seem to pass the video params correctly in the SDP, but
Freeswitch still responses with the following SDP:
   v=0
   o=FreeSWITCH 1428032845 1428032846 IN IP4 X.X.X.X
