If you want to start streaming NOW at zap.stream,this is what you need to do:

HLS stands for HTTP Live Streaming. You stream using a streaming software like OBS and connecting it to a HLS service provider like Cloudflare or Owncast (this is a little more technical) via RTMP under streaming section in OBS.

Cloudflare is 5$ a month but it’s very easy to use. Just create an account and then go under streaming section, then click on “live” and create a “live input” it will give you the RTMP address and a key. Paste that into your OBS; Hit start streaming and then you get the HLS address at cloudflare. That address then you can paste it at zap.stream and you’re good to go.
