Video stream bandwidth issue

Is video stream bandwidth affected by TCP bandwidth? Or is it affected by UDP bandwidth?

If there are more than 4 or 5 participants, a black screen of Inactive status occurs. The jvb log says not enough bandwidth. I would like to measure the bandwidth, please tell me the TCP or UDP standard.

Media primarily flows through UDP, if available. TCP is a fallback.

What is the recommended bandwidth for jvb video stream? If there are more than 4 participants, it will remain in the jvb log due to inactive black screen and insufficient bandwidth when in tile view mode.

Does it change if I install it with Ubuntu without using docker-jitsi-meet ?

Network speed in tile view mode with video on all 5 browsers on the local PC is as follows.

However, inactive black screen phenomenon occurs.

The jvb log also says it’s a bandwidth problem.

What the hell is wrong with you?

Is that saying 100% of your CPU is being used? If so, that’s your problem.
