That's an awesome offer, yeah let's do it.
Nostr streaming events need a video playback URL so that whatever client (Zapstream Amethyst etc) can play the video.
If you host your own (e.g. SRS, OME) or use a video infra platform (API Video, CloudFlare, Mux, etc) they will give you that URL as standard so you can embed it wherever you like
Unfortunately most of the consumer brand platforms (Twitch, YT, FB, Tiktok, etc) intentionally try to hide that b/C they want to keep viewers locked to their platform. There are ways to get it anyway (e.g. streamlink) but not trivial and always against TOS.
If you'd like to quickly set one up I recommend API.video it's like one or two clicks and you're done. Or if you'd like to host your own SRS is a single docker compose and done.
You can even run your own Zap-Stream too if you like! I am not an expert at it but I did run an instance so I could test the build and it works well after a little setup.
