Hi Geeks,

I am trying to implement a conference in mux mode and FreeSWITCH send canvas properly but never show video on but a pic "Video Muted (but audio not affected)" pic in place of every member's video on canvas. I tried a lot with no success :(

OS : Ubuntu 14.04.5 LTS trusty

FreeSWITCH Version 1.9.0+git~20181120T210412Z~968c76b29c~64bit (git 968c76b 2018-11-20 21:04:12Z 64bit)
