Stream Key property

[ArtiomShapovalov]

Hey! Question about your rtmp broadcast code. I want to stream to Twitch from iOS broadcast extension and Twitch requires to send a stream key alongside with stream URL. I can't really see from a source code where I can put a stream key.

Also, I wonder, is there any difference in broadcasting a stream from Metal and broadcasting a sample buffer from the broadcast extension (it broadcasts a device screen)

Very appreciate your help)
