Answer 2

You have written the correct answer based on what you asked. Answering your question in the comment:
The cheapest way if you have a smartphone is to broadcast from the smartphone's camera. We are looking for some software (for iOS / Android): Teradek
There is another software that broadcasts directly to youtube with chat, but I don’t know which one.
Search keywords: RTMP Stream, Broadcaster, Broadcast
If we are talking about a device that broadcasts a better picture, for example, from a gopro or a camera, RTMP Encoders are needed. The cost starts from $1k. Try to write @alexpirey on Instagram. He is a director and thoroughly understood what and how it works, how to broadcast. He sometimes broadcasts to the periscope and YouTube simultaneously from the camera of the car in motion.
Actually, everything cost us $1700, only a piece of iron for broadcasting + a camera for rent, on the advice of this person. Everything is good - everyone is happy.
