Question 1

How to set up an Nginx RTMP server for iOS live streaming?

Accepted Answer

Follow the README's guidance using the nginx-rtmp-module; install Nginx with RTMP support on a server like Ubuntu, then configure it to handle RTMP push and pull streams for broadcasting.

Question 2

What's the difference between RTMP and HLS for live streaming on iOS?

Accepted Answer

RTMP uses TCP for low-latency streaming but is proprietary, while HLS uses HTTP with segmented files (.ts) for better compatibility but higher latency. This project uses RTMP for simplicity, but HLS is often preferred for iOS playback.

Question 3

Compare LFLiveKit vs other iOS streaming libraries like HaishinKit.

Accepted Answer

LFLiveKit, used here, is focused on RTMP pushing with a straightforward API, but HaishinKit offers more features like RTMP/HLSPublishing and is actively maintained. LFLiveKit may be simpler for basic needs.

Question 4

How to add real-time comments to a live streaming app in Swift?

Accepted Answer

This project uses Socket.io to emit and listen for comment events; implement similar WebSocket logic in Swift to send and receive data, updating the UI dynamically as shown in the client-side code.

Question 5

Best practices for reducing latency in iOS live streaming apps?

Accepted Answer

Use RTMP for lower latency, optimize encoder settings in LFLiveKit, and ensure a stable media server setup. This project demonstrates the basics but doesn't cover advanced optimizations like adaptive bitrate streaming.

Question 6

How to scale a Socket.io server for live streaming events?

Accepted Answer

The provided server is basic; for scaling, consider using Redis for room state management, load balancing, and horizontal scaling, which this project doesn't address.
