Configuration Issues

Hi,
Here Jitsi Server URL https://jitsi-meet-galaxy.galaxysofttech.co.in

We are following the quick-install document and successfully installed Jitsi-meet with Jibri of following system configuration.

  • 100 GB HDD
  • 8GB RAM
  • c4.xlarge
  • Server bandwidth: 10gbps

After that we have to get the following issues:
1]There is a delay during video streaming.
2]Jumping in/out videos.
3]Video is getting stuck so many times with more than 5 users.

So please do needfull your suggestion on this.


Thanks & Regards,

I just did a quick test locally and it seems to work fine. Video started quickly and ramp up quickly…

What browsers are you using? Are you sure some of the issues you see are not because of the clients network?

We are using Google Chrome with the latest.

Hi, thanks for giving replied.
https://meet.jit.si/ is working fine at my network but we were installed https://jitsi-meet-galaxy.galaxysofttech.co.in in a server, so here we are facing issues as I mentioned above/below.

1]There is a delay during video streaming.
2]Jumping in/out videos.
3]Video is getting stuck so many times with more than 5 users.

Here are the installed configuration file, so please see if change needed let me know.

I tested it and video came up very quickly.

I do not understand this.

You say you got freezes of the videos, right? Have you checked during those freezes do you see any spikes of network or cpu usage on the server?
What is the OS and version on the server? Can you check whether the sysconf are set and taken into account on your box: https://github.com/jitsi/jitsi-videobridge/blob/master/config/20-jvb-udp-buffers.conf

OS and Version:

Here is the location of the buffer configuration file:
root@jitsi-meet-galaxy:/# cat /etc/sysctl.d/20-jvb-udp-buffers.conf

this sets the max, so that we can bump the JVB UDP single port buffer size.

net.core.rmem_max=10485760
net.core.netdev_max_backlog=100000

Check the values using the sysctl command. Are those set? Check performance of the machine while you experience the problem, as at some point we had been using c4.xlarge for jvb and we didn’t have problems. What is the RTT to that machine, is it close to the participants?
Currently it works very well for me I see something like 80ms RTT to the machine when in a call (if I’m reading the webrtc-internals correctly):

Thanks for the Quick response.
What we are facing is that, whenever we add more than 5 user in a conference even the 6th user our in house Jitsi server failed and one of our users video call has been drop. We analysis the JVB log and found the following log. Kindly refer the log below:-
