Last-n configuration

Hi all,

could you suggest me the best configuration of the last-n parameter for the following scenario:
only one moderator who shares the screen & 20/25 guests (no need to share your screen)

Thanks

one moderator can share screen/video (and should see all guests video … or no video?)

lastN is more about dominat speaker, auto-switching video and so on
channelLastN parameter/configuration is maybe what could usefull for you
otherwise work/develope with the external_api … cut down functionality/user-interface like you need it…

Is correct, one moderator can share screen and should see all guest video.

I try with channelLastN configuration

My goal is to minimize bandwidth and CPU usage

in “/etc/jitsi/meet/YourDomain-config.js” look at
constraint … lower the video-resolution min/max values … saves bandwidth
disableAudioLevels … reduces CPU usage on client-side (read here more about)

and of course think about supported browser for your jitsi …
jitsi doesn’t really support firefox simulcast yet and thats causes some CPU spikes and other problems, like higher traffic and so on (see)
