A followup: We tried the server today, with video, with seven people. There were lots of problems where different people weren’t shown some other people, just blank white boxes. (Some were close to square, others wide but not high; we suspect the latter were people who had chosen the Don’t Show Video option, but the former had opted for video—and in fact could see themselves—but some problem prevented some others from seeing them.)
One other person got errors saying the video was being used in unsafe ways.
We ended up turning video off and using audio only—which was still quite useful.
And we used zoom to screenshare the PDFs of the sheet music.
I just scheduled a Swarthmore sing for 1:30pm EST this Saturday, and plan to give the video portion a try rather than a concurrent Zoom session.
But I also use zoom’s screen-share feature to enable everyone to see the sheet music of whatever we’re singing at the moment; can you think of any way for me to duplicate that via your server?
