Multichat in ios app?

Question

iOS

The task is simply this - to make an application that, by geolocation of a person, will show a regional chat.
As a result, there will be about a hundred such chats. An event is announced in a certain area (say, a chess championship), and accordingly the event chat is made. The chat should also have live streaming, possibly with a recording function. So that someone can stream this event on their phone, and "losers" who did not get to see it in real time, and if later, then view the recording.
The server itself is YET intended to be done in Python (but not a fact).
We rest on:
1 server capacity for such chats.
2 Streaming and storage.
Advise, plz, what can be used for such chats, and what for video streaming and recording / storage of these videos.
Ideally, I need something like using the telegram api, and making such chats in the application built-in. And YouTube API for live streaming and recording. It's just like a spherical idea in a vacuum, I understand that it's not solved like that, I just designate the vector in which direction I'm thinking about the solution now. Can eat something real, or offer to solve in absolutely other ways?

Answer 1

1. For chats, use JSQMessagesViewController
2. Socket.io for exchanging messages in chat
3. LFLiveKit for streaming
4. IJKPlayer for playing streams
5. Nginx RTMP module as a media server
To record video, you need to add the option in the rtmp module settingsrecord all;
