I figured out that during the screen sharing session, the simulcast is still enabled. It should be disabled, right?
How did I realize?
I have a Ubuntu (18) server on EC2 AWS that is installed Jitsi follow the guide here
When presenter is showing screen, on another participant I try to descrease the quality from HD to SD/LD. I can see the presenter’s screen is going bad quality. I never see the same behavior when using jitsi offical meeting system (meet.jit.si)
Further checking, I see on the presenter’s browser, there are 3 streams are sent out. (using chrome://webrtc-internals). Compare to the meet.jit.si, only 1 HD stream is sent out.
I doubt that I missed some configuration, but I don’t know what it is. (My configuration config.js is default)
Could you guys advise me for this case?
