How did I live stream grilling a steak from my phone yesterday? I'm glad you asked!
First, you need a live video streaming app on your phone. I used Larix Broadcaster. It's available for both Android and iOS.

Next, I visited https://zap.stream/settings/stream from Kiwi browser and signed in with my Nostr Connect browser extension. Once signed in, I configured my stream settings and paid the Lightning invoice to allow me to stream. I paid 1K sats and chose to use the best quality.
Then, I opened Larix and went into settings to add a new connection. I added a zap.stream connection with the stream URL and stream key that I obtained above.
Finally, I edited my stream name from my https://zap.stream/dashboard and tapped the camera shutter button on Larix.
Boom. Zap.stream live streaming from mobile.
The only real issue is being unable to view comments on mobile. You need a second device to do that. Though, I wonder if I could have split screened it? Probably. It would have been very small though.
Good luck!
