Performance optimization / Jitsi with separate videobridges, rather poor quality

Hi,
well the changes to sysctl don’t seem to have improved the situation very much.
So now i would like to upgrade to jvb2.
As we experienced a bit of trouble doing so in the past, is there any “easy walkthrough of upgrading jvb1 to jvb2” including the separate videobridges, we could follow?
thanks
Sascha

ok folks.
got jvb2 running on all three nodes.
But unfortunately we still have serious connection issues.
Actually it even looks like perfomance is worse than with jvb1.
Allthough attendees have a very fast and stable connection, Jitsi gives them a red or yellow connection icon, from time to time. Video / audio are far from in sync most of the time.

Would really appreciate some hints if you have any.
Tell me which config files you would like to see, and i will be very keen to provide them.

thanks
Sascha

Hey bridge team @bbaldino @Boris_Grozev @Jonathan_Lennox any ideas?

Ok, here are the configuration files as they are currently activated on the main jitsi vm.

/etc/prosody/prosody.cfg.lua
/etc/prosody/conf.avail/vc.foo.bar.cfg.lua
/etc/jitsi/meet/vc.foo.bar-config.js
/etc/jitsi/jicofo/config
/etc/jitsi/jicofo/sip-communicator.properties
/etc/jitsi/videobridge/config
/etc/jitsi/videobridge/sip-communicator.properties
/etc/sysctl.conf

looking forward to hear your remarks and ideas,
thanks a ton
Sascha

Unfortunately it is getting even worse here now.

We now have the problem of participants not seeing all attendees when logging into a meeting room.
The new attendee only sees one other user, but without video / audio, while two other users do see and hear each other in that room.
After a couple of login retires (up to 15 times) the connection with 3 users will be established and works.
So basically meetings with more than 2 users are not really possible atm.
We have strange Jigasi errors in our jicofo log, allthough jigasi is not even installed, don’t know if that is relevant:

org.jitsi.jicofo.jigasi.TranscriberManager.log() Error finding room for null

also some of these warnings:

org.jitsi.protocol.xmpp.AbstractOperationSetJingle.processJingleIQ().368 unsupported action session-terminate

please help me…i don’t really know what to do right now.
thanks

My users are helped a-lot by disable measuring audio levels and rendering of the blue “i am talking dots”
disableAudioLevels: true,

This setting along reduces CPU load on slower client computers 70% and will improve audio performance.
A lot of the errors you see in the server log originate from overloaded client computers.

hi xranby,
thanks, will try that instantly!
but can this setting really trigger the “more than 2 users have difficulties to meet in one room” problem?
Any additional hints highly appreciated!

thanks
Sascha

edited the file as xranby said.

And i can see two users on my mobile, and only one user on my notebook…
I just don’t get it.

ok, i can confirm, that video / sound / performance seem to be much better now, after disabling audiolevels.
However, we seem to have a split brain scenario here, where, startiing with 3 users, everybody has a different view.
For example:
first user sees / hears everyone
second user sees / hears himself and one other
third user sees 3 users but only hears one

What can that be?
Obviously this is a show stopper at the moment…

thanks again
Sascha

Can you post the jicofo log , and the logs from all three video bridges?

sounds like a bug in the OCTO bridge synchronization.
without OCTO all users in one room should use one videobridge.
with OCTO users should be split up using all videobridges.

Do the “split brain scenario” appear if only ONE bridge is active?

yes, we stopped the other two, and we still had these problems

can you try disable p2p mode so that all communication uses the bridge?
p2p: {
enabled: false,
}

here’s the log files.

Sorry…wasn’t able to upload it in any other way…

thanks
Sascha

i suppose you would like to read the logfiles before i edit p2p to false?

I looked at the jicofo log WARNUNG’s and odd information.

  1. Not merging A/V streams from A to B
    Jicofo 2020-04-15 09:59:40.625 INFORMATION: [48] org.jitsi.jicofo.LipSyncHack.log() Not merging A/V streams from rmsrabel@conference.vc.foo.bar/144f655e to rmsrabel@conference.vc.foo.bar/b05eea8b

  2. it looks that all three videobridges uses the same login i think this is an error *

  3. missing pub-sub configuration, i think this is a requirement when using external videobridges *
    Jicofo 2020-04-15 09:48:50.448 WARNUNG: [30] org.jitsi.jicofo.bridge.BridgeSelector.log() No pub-sub node mapped for jvbbrewery@internal.auth.vc.foo.bar/7a882c9b-b169-49ac-bc0c-c3df680efdd4

I do not know if 0. is an issue.

I base my two remarks 1. and 2. on how to setup more than one videobridge and configure pubsub using this video tutorial:

I think muc is now replacing pubsub (when using jvb2), and we consider it correct to use the same login for all videobridges.

Are we wrong?

thanks

Good morning,

no ideas anymore?
We’re still suffering from really odd performance issues we can’t explain.
More examples:

  • yesterday at 10 pm out of 2 external partners only one came into the chat. Thousands of restarts, different device … everything tried. Nothing.
  • yesterday at 8 pm 1:1 session
    The latency was around one second, video and sound quality were good.
    However, the sound changed after a short time, my counterpart suddenly heard me distorted, although my line was good, the mic definitely ok.
    In direct comparison with Skype this problem did not exist.
    Back in jitsi the same problem after a short time!

P2P is disabled at the moment
disableAudioLevels set to true

i am getting desperate here…
thanks
Sascha

Are your VM’s setup to make use of hardware encryption?

Also try using 480 resolution.

Above two changes together with enough CPU (10 cores) and enough memory helped us a lot. We were suddenly able to do conferences with 20 people. Had similar problems like you before. We’re running on unstable branch.
