[Freeswitch-users] Webrtc no video

Wed Jan 7 03:23:23 MSK 2015

Hi folks,

I have just installed freeswitch with a basic configuration. Actually,  
i trying to get to work a call with video. I'm using sipjs to set up  
my client. Each call has audio but no video.

After some days checking the docs and some test, i don't really know  
where could come from this problem.
Maybe the codec.

Here, from fs_cli, the codecs list i have installed:

===
codec,ADPCM (IMA),mod_spandsp
codec,AMR,mod_amr
codec,G.711 alaw,CORE_PCM_MODULE
codec,G.711 ulaw,CORE_PCM_MODULE
codec,G.722,mod_spandsp
codec,G.723.1 6.3k,mod_g723_1
codec,G.726 16k,mod_spandsp
codec,G.726 16k (AAL2),mod_spandsp
codec,G.726 24k,mod_spandsp
codec,G.726 24k (AAL2),mod_spandsp
codec,G.726 32k,mod_spandsp
codec,G.726 32k (AAL2),mod_spandsp
codec,G.726 40k,mod_spandsp
