How to Go Live on Twitch with Your Phone Using SRT Relay

March 21, 2026

What Is IRL Streaming?

How IRLHost works: Your phone streams to your IRLHost relay server, which forwards the stable stream to your OBS at home. OBS then sends it to Twitch, Kick, or YouTube. IRLHost is the relay between your phone and OBS — not between OBS and your streaming platform.

IRL (In Real Life) streaming means broadcasting live from outside — on the street, at events, travelling, or anywhere that is not your desk. The challenge is that mobile networks are unstable, and a standard RTMP stream will drop, freeze, or disconnect constantly when you are moving around.

The solution is SRT — a protocol designed for unstable networks that can recover from packet loss and reconnect automatically. Pair that with a relay server and you have the foundation of a professional IRL setup.

What You Need

  • A smartphone (iPhone or Android)
  • A computer at home running OBS (almost any modern PC or Mac works)
  • A streaming app that supports SRT — Moblin (iOS) or IRL Pro (Android)
  • An SRT relay server — we will use IRLHost
  • A Twitch account

That is it. No encoder box, no backpack full of equipment required for a basic setup.

Step 1: Get Your SRT Relay

Sign up for IRLHost at irlhost.gg. Create a relay server and note your SRT ingest URL and stream key. Keep these handy — you will need them in OBS and your phone app.

Step 2: Set Up OBS on Your Home PC

Open OBS on your home PC. Go to Settings → Stream and enter your Twitch stream key — this is where OBS sends your stream out to Twitch, exactly as with any regular stream.

Then in your OBS scene, add a Media Source pointing to your IRLHost SRT ingest URL. This is how OBS receives the stabilised stream from your phone via IRLHost. Your Twitch stream key lives in OBS — not in IRLHost.

Step 3: Set Up Your Streaming App

On iPhone (Moblin): Go to Settings → Stream → select SRT or SRTLA. Enter your IRLHost relay address and stream key. Set latency to 2000ms to start.

On Android (IRL Pro): Go to Settings → Stream → select SRT or SRTLA. Enter your IRLHost server, port, and stream key. Set latency to 2000ms.

Step 4: Go Live

Start streaming from your phone app. Check your IRLHost dashboard — you should see an active inbound connection. Verify OBS is receiving the feed (the Media Source should show your camera). Then go live in OBS. Open Twitch on another device to confirm you are live.

Tips for a Better Stream

  • Use two connections: Enable SRTLA bonding in Moblin or IRL Pro to use WiFi and mobile data simultaneously — much more stable than either alone
  • Bitrate: Start at 3000-4000 kbps. Lower if you are in poor signal areas
  • Battery: Streaming drains your phone fast. Bring a power bank
  • Audio: The built-in microphone is fine to start. A clip-on Bluetooth mic makes a noticeable difference

Next Steps

Once you are comfortable with the basics, look into SRTLA bonding for better stability, and consider a dedicated streaming backpack setup if you plan to stream long sessions.
