youtube and other steaming platforms use a lot of servers to handle the load, so no jitsi can't be youtube itself unless you have a beast of a connection and even then you'd cap your connection after a hundred users. CDNs like cloudflare does the same but for websites.
I already have a lot of servers. I was asking if jitsi is server side software that can handle the encoding / delivery to users. The answer is no. Jitsi is apparently completely unscalable.
