I like Jitsi because it doesn't require any signups and it's simple to create a channel/room. But the quality of video and audio seems a bit lacking. Does anyone have suggestions on how to improve Jitsi Meet's video and audio quality when working with the official smartphone apps and platform (not self-hosted)? Sometimes (on a broadband connection), for some participants, the video from a broadcaster freezes once in…

Are any of the participants using Firefox by chance? There are known issues being worked out ¹, some in collaboration with Firefox itself ², to improve performance and compatibility.

For now, it seems the best audio/video quality can be achieved by all participants using a Chromium-based browser such as Chrome and Edge.

We did our daily standup call with it yesterday (mostly audio). 12 people, on a $3 Scaleway Debian instance (2GB RAM). Worked perfectly. Obviously as we stopped using Zoom we have to manually upload all our personal data to Facebook now.

We tried to but with most of our team on Firefox it simply doesn't work unfortunately. Zoom has been the only thing reliable for us. It's a bit ironic that somewhere, someone is switching from Firefox to Chrome because of data concerns with Zoom.

That's odd. My experience with Firefox on Windows is that I can't get audio to work with Zoom. Jitsi, on the other hand, works perfectly though there is a small yellow box that warns me that I should use a "fully supported browser"

Have you tried BigBlueButton?

Something that isn't mentioned in the docs is room (and server) capacity, or at least rough estimates. The Jitsi team gave some specific numbers on room capacity in the forums. Each room should reliably handle 20-35 Chrome users (Firefox uses roughly double the resources), and has a cap at 75. Apparently if you're only using audio, then rooms of 70+ people will work fine. They're working on upping this number to 500…

Unfortunately from my experience, Jitsi does not reliably handle 20-35 users

Any Firefox users among those?

in Zooms webclient for audio to work with Firefox you'll need current Nightly, staged to be released as version 76 in May. Edit: another poster linked the bugzilla issue for AudioWorklets

Thanks. I know about the Firefox issue, but all participants are on mobile — mostly Android and some iOS — using the official Jitsi Meet app.

You can override configuration options by appending `#config.optionname=value` to the meeting url in a fresh new browser tab

Which configurations can ensure video and audio at a good enough quality with audio being clear and video not dropping frames (even if the video is a bit blurry, that’s fine)?

I am on ubuntu 18.04 lts using firefox and jitsi hard locked my machine, it was still sending packets, but all UI was frozen, I had to power cycle the machine.

On osx using chrome, it was flawless.

What about the cost in terms of per person per hour?

Depends on the bandwidth charges of the SFU host, mostly that means computing the volume (5.5Mb/s * participants * duration) though some hosts aren't volume billed in which case it might then be a matter of whether sufficient data rate available (drop the duration) or paying for the peak consumed. That's just the A/V conferencing not file sharing or other incidentals one often finds useful.
