How to configure SRT connection for a 1-to-2 setup (one listener, two simultaneous players)?

Question

Hi,

I would like to ask whether it is possible to configure an SRT connection to support a 1-to-2 setup — specifically, one listener receiving the stream and two caller devices playing it concurrently.

In my use case, I need to distribute the same live video feed to two playback devices on the same network.

Background / Tried Steps

Listener:
srt://192.168.2.39:9991?mode=listener

Caller 1:
srt://192.168.2.39:9991?mode=caller&streamID=123

Caller 2:
srt://192.168.2.39:9991?mode=caller&streamID=456

Could you please advise whether this scenario is supported, or if there is a recommended approach for allowing multiple players to receive the same stream from a single listener?

Environment

• iPad mini 7
• iPhone 16 Pro
• iPhone 11
• Haishinkit master branch

Thank you very much for your guidance.

No way. SRTConneciton supports a one-to-one connection. Multiple connections cannot be established.

HaishinKit.swift/SRTHaishinKit/Sources/SRT/SRTConnection.swift

Lines 6 to 9 in 1c65a96

	/// An actor that provides the interface to control a SRT connection.
	///
	/// Supports a one-to-one connection. Multiple connections cannot be established.
	public actor SRTConnection: NetworkConnection {

I think it should work if you set up two listeners. You’ll need to use separate ports.

srt://192.168.2.39:9991?mode=listener
srt://192.168.2.39:9992?mode=listener
