[jitsi-users] A few questions about Jitsi


#1

I have a few questions about Jitsi and webinar software for Linux. I would appreciate if someone could answer them for me.

1.) How many people can do video chat in Jitsi at the same time?
2.) how many people can do text chat in Jitsi at the same time?
3.) How does jitsi meet compare to citrix gotomeeting and gotowebinar?
4.) I noticed a lot of video confrence software even in the open source space
uses flash, including the apache project openmeetings, does jitsi use flash? Does jitsi need flash?
Could we use gnash instead?
5.) Where can I find others (preferably english speaking) as interested in testing jitsi as I am?
6.) If one person does video chat does that limit the total number of participants?
7.) When will I be able to get commercial support for a 100% free software webinar solution?

I have a few questions about Jitsi and webinar software for Linux. I

My company provides commercial support for Jitsi Meet, which is what I
guess you are referring to, it is the closest thing to a webinar
platform among the Jitsi products.

1.) How many people can do video chat in Jitsi at the same time?

That depends on several things, but according to a recent stress
test[0] you can have ~1000 video streams running through a lower
spec dedicated server while using a bandwidth of ~500Mbps. It's the
bandwidth that can be the bottleneck if you target lots of
participants.

On the client side you don't need much, especially if you have Last-N
enabled[1] and your peers get and see only several of all the streams.

2.) how many people can do text chat in Jitsi at the same time?

That would be a limitation of the XMPP server, we didn't have such
tests and I guess this is not a real-world limitation -- the video
streams server bandwidth is more important.

3.) How does jitsi meet compare to citrix gotomeeting and
gotowebinar?

First of all Jitsi Meet is free software, with all the benefits you
get from this -- you know what's inside, you can have it changed and
you can host it in a secure location of your choice.

You don't depend on some other company that is hosting it for you by
overselling it and overprovisioning it.

You can have it branded with your logos and customized to your needs.
You can have SIP integration and add telephone users to the call. You
can have recordings of the web conferences, share presentations, edit
collaboratively text documents, share screens.

Also everything is encrypted.

4.) I noticed a lot of video confrence software even in
the open source space uses flash, including the apache project
openmeetings, does jitsi use flash? Does jitsi need flash? Could we
use gnash instead?

No flash/gnash needed. You don't need anything else than a modern web
browser. No plugins. You'll need a chrome extension if you want to
share your screen, but you need nothing additional if you are just
watching.

5.) Where can I find others (preferably english speaking) as
interested in testing jitsi as I am?

This ML is such a place :slight_smile:

6.) If one person does video chat does that limit the total number of
participants?

You mean if the platform is used for something like a webcast? It's
not meant to be a webcast solution, it is used for webconferences,
where all the participants can have their videos streamed (they could
turn them off, of course).

So if you are looking for a solution for webinars that are more
like webcasts, with one person speaking and hundreds or thousands of
others just listening, then Jitsi Meet may not be the best tool.

7.) When will I be able to get commercial support for a 100% free
software webinar solution?

Please feel free to contact me personally if you have more specific
questions.
