Lee,
Your idea is a superb one which I fully support. As I see it, live coverage of Lancaster Town Council sessions in 2021 would be the local equivalent of the 1979 advent of C-SPAN coverage of Congressional proceedings.
As I understand things from what I consider to be a credible source, YouTube live coverage/archiving is done this way:
There are two separate streams, live and YouTube.
When live streaming is linked to YouTube, the coverage is simultaneous and live. By linking to YouTube, the live stream is then recorded and preserved on YouTube.
Also, unlike live streaming on FB, YouTube provides closed-captioning and subtitles.
The number of cameras used depends on to what extent the organization wants to "pan" the entire setting.
I think I got that right.
