Recently I've seen people doing nice things using Open Broadcast <br>
Platform (OBS). Apologies if this has been mentioned. For Zoom it seems <br>
you need to install some sort of virtual camera plugin for Zoom to <br>
target, but OBS is really meant to live stream (1984Tube, twitch, etc).<br>
<br>
That said I've not been able to get it to work myself on Mac (it might <br>
have something to do with graphics acceleration, not sure). The examples <br>
I've seen have been from Ubuntu and when it works, it's very nice and <br>
create quite an interactive and professional looking environment. This <br>
includes streaming videos playing on the host, etc. YMMV.<br>
<br>
Also for Zoom, like most I've been on some pretty large calls these daze <br>
and the general advice is that everyone mutes their mic and turns off <br>
their camera to be thrifty with the explosion of bandwidth.<br>
