Hello!

By default, as described above, Jitsi Meet server allows only to create video conferences using defined Jitsi Meet server (you can change server in Messenger settings, by default it is free meet.jit.si server). If you like to have ability to stream and record videos you should install Jibri and connect it to your Jitsi Meet server, after that you will have in Messenger's Jitsi video popup two new options to record and stream videos like on image below. 

So, both these functions depends on your Jitsi Meet server but not on the Messenger, we don't need to add anything specially for it to the Messenger.

About streaming: By default Jitsi can stream only to YouTube rtmp server, but we can modify it and make it to stream to any other rtmp server. If you have rtmp server which supports comments and views of thousands people we can do it, but in this case we should configure your Jitsi Meet and Jibri servers, but not Messenger module.
