When doing a video conference, there was a problem that a black screen often appeared.
Then the existing developer could not solve this problem and left the company.
Then suddenly the jitsi project was assigned to me. But i don’t know what jitsi is.
My company told me this.
‘Look at the vm and specs now and prepare for expansion’
I don’t know what this means. So I posted this question.
Perhaps the my company thinks the cause of the black screen is high load.
This may be another issue related with the client-side. First you need to be sure about the cause. If it is not related with the server resources, you cannot solve it by increasing the resources on the server-side.
First of all you should start to monitor your jitsi infrastructure components: CPU load, network usage and jitsi connected participants.
Then you should determine in which cases you see your video issues : on all conferences, only when the number of participants increase…
There is a lot mechanism in the jitsi infrastructure that can reduce the number of video displayed in a conference to reduce the load.
The capacity of your jitsi infrastructure really depends on your mean conference size and the number of video stream that are displayed by clients.
The black screen doesn’t happen all the time, it happens irregularly.
Strangely, when I rebooted the bridge server, the black screen didn’t occur for a while.
So, we are rebooting the bridge server every week.
Currently, each of our bridge VM has (16Core of CPU and 16G of Memory) * 4,
and it is said that it can handle 100 * 4 concurrent users.
(I heard that it can handle a total of 400 concurrent users)
I’m trying to figure out various causes through this site.
