Videoconferencing is the method of choice for contact to the world at present. A lot of project-groups with including me, use it. The only tool with data protections, as far as I know, jitsi-meet. The connection to the server and the connection from server are https-protected. The audio- and video-data on the server are open. The server operator must be trustable. The idea is obvious, to operate the server itself. The best is trustable himself.
I beginning with download jitsi and installed on my x86-computer with ubuntu 18.04. Therefore are a lot of instructions on the internet. The installation was possible with less problems. I created in the router forwardings for port 80, 443 and 10000/udp. After this it was possible to communicate with extern participants with audio and with video together. The utilization of my 4 cores was at 30 percent. Thanks to the developer of jitsi.
The installation on my working-computer has are negative side, I must open the forwardings to my intimate internal of my network and I must switch on my computer permanently - not a permanent solution.
Afterwardst I installed ubuntu 18.04 on my raspberry pi version 4 and then jitsi with the instructions above.
I was surprised. The connection was immadiatly established between my tablet and my computer with audio und video. But, by additional inspection make it clear, this function is only possible with two participants and only possible in my own network. If the instance calles from outside, then you will see the windows for the particpants, but those are black - no video and no audio. Only chat is possible.
My java version:
openjdk version “1.8.0_252”
OpenJDK Runtime Environment (build 1.8.0_252-8u252-b09-1~18.04-b09)
OpenJDK 64-Bit Server VM (build 25.252-b09, mixed mode)
In the log-file /var/log/jitsi/jvb.log are writing permanently:
