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 codec,G.726 40k (AAL2),mod_spandsp codec,G.729,mod_g729 codec,GSM,mod_spandsp codec,H.261 Video (passthru),mod_h26x codec,H.263 Video (passthru),mod_h26x
