Tl;dr: I tried running galene for a book club last night and ran out of bandwidth.
I’m in a virtual bookclub and the normal (zoom) host wasn’t available, so I offered to host on galene.
I span up Galene on a octocore ARM64 ubuntu device - on my home VDSL - with a limited uplink of 17 Mbit/s.
(70/17)
It worked well then fell over when 8 people showed up and I ran out of uplink.
So I’m wondering - would it be possible to tell Galene what the total uplink available is and have it throttle back the senders to stay within that? Or is this such an edge case that no-one else would be as foolish as me?
Thanks.
Tim.

This should happen automatically : congestion control should kick in, and
Galene should either peel SVC layers or throttle the sender (depending on
your codec) until the traffic fits within the link's limitations.
Obviously, that didn't work in your case. What codec were you using, and
what web browser was the sender using? Were the receivers connecting
directly to Galene, or were they going over TURN ?

I was thinking the fact that the limitation is shared across all 7 remote users
(I was local on the same lan as the Galene server)
may have confused the situation - along with the fact that it is a massively asymmetric link.

VP9 and no TURN - I’m old/lucky enough to have a /24 routed to my house :-)
I think I was using chrome, but it may have been safari on Mac - at least 2 of the others were safari on iPad.
I’d guess the rest were chrome on windows.

No, that should still work.

Ah. I'm seeing issues with VP9, which is why I've reverted the switch to
VP9 and have come back to VP8 as the default codec. I believe it's
a browser issue, but haven't had the time to do any serious debugging.
I would be grateful if you could try to reproduce the issue with VP8 and
let me know how it goes.
