What do I need to start IRL streaming?

A phone with an encoder app (Moblin, IRLPro or Larix), an EU relay endpoint for RTMP, SRT or SRTLA to reach OBS from anywhere, OBS Studio on your PC, and one reasonably stable internet connection.

Do I need SRTLA bonding for IRL streaming?

Only if you're moving through spots where no single connection holds up, a driving vehicle, tunnels, or dead zones. On solid city 5G, Wi-Fi, drone or encoder feeds, a plain single-connection SRT endpoint is simpler and enough. StreamRelay supports both: use SRT for a simple single-connection setup, or SRTLA to bond multiple connections (e.g. two or three SIMs) into one resilient stream.

Is SRT or RTMP better for IRL streaming?

RTMP is the paste-and-go default and works almost everywhere. SRT has lower latency and recovers better on shaky cellular, so most IRL streamers prefer it outdoors.

Why use an EU relay for IRL streaming?

Routing through DE-CIX Frankfurt keeps EU latency low versus bouncing through the US first, it's GDPR-compliant and EU-hosted, your stream keys stay yours, and there's no port forwarding or Linux server to run.

IRL Streaming: The Complete Beginner's Guide (2026)

Q: What is IRL streaming?

IRL (in real life) streaming is broadcasting live from a moving camera, usually a phone or an encoder camera, over mobile data or Wi-Fi, instead of from a fixed studio PC. For the OBS setup in this guide, the feed travels phone/encoder → relay → OBS → Twitch, YouTube or Kick. Streaming straight from a platform app does not require a relay.

IRL (“in real life”) streaming means broadcasting the real world live, walking around a city, at an event, from a drone, instead of from a desk. This guide explains how it works in plain terms, what you need, and how a StreamRelay EU relay gets your camera into OBS reliably. A relay is just a server in the middle that catches your video and hands it on, we’ll explain it as we go.

What is IRL streaming?

IRL streaming is live broadcasting from a camera that moves with you, usually your phone, or a camera plugged into an encoder. An encoder is the app or device that turns the camera picture into a stream the internet can carry (popular ones are Moblin, IRLPro and Larix). Instead of broadcasting from a fixed studio PC, you go live over mobile data (cellular) or Wi-Fi.

For the OBS setup in this guide, your device sends to a relay, OBS pulls the live feed in and broadcasts your finished scenes to Twitch, YouTube or Kick. You can also stream straight from a platform app without a relay if you do not need OBS.

IRL vs studio streaming

A studio stream usually starts in OBS on a computer with a fixed internet connection. An IRL feed starts on a mobile device. To use your OBS scenes on the go, send the feed to a relay that OBS can reach. Your phone and OBS both make outgoing connections, so this setup does not need an inbound port forward at home.

What you need for IRL streaming with OBS

A camera or phone, a modern phone is enough to start.
An encoder app, the app that packages your camera into a stream: Moblin (iOS), IRLPro (Android), or Larix (both).
A relay endpoint between you and the platform, this is your StreamRelay ingest URL (RTMP, SRT or SRTLA), the “address” your phone sends video to.
OBS on a PC at home to compose your scenes (overlays, alerts, layout) and push the finished result to the platform.

How an IRL stream actually flows

Your phone/encoder sends one stream up to the relay, using RTMP, SRT or SRTLA, the common ways to carry live video.
The relay receives it in the EU, currently at DE-CIX Frankfurt (a major internet hub, more on that below).
OBS pulls the feed back down from the relay as a Media Source, basically OBS treats the relay like a camera it can read from.
OBS outputs your composed scene to Twitch/YouTube/Kick.

Choosing your protocol: SRT or RTMP

Think of RTMP and SRT as two different “delivery methods” for your video. RTMP is paste-and-go and works almost everywhere, the safe default. SRT has lower latency (less delay between real life and what viewers see) and recovers better when a cellular signal gets shaky, because it’s built to cope with patchy connections. Most IRL streamers prefer SRT outdoors. When a single connection is not enough, SRTLA (built on SRT) bonds several connections into one. Full breakdown: SRT vs RTMP.

SRT vs SRTLA bonding: do you actually need bonding?

SRTLA bonding combines several internet connections at once, such as multiple SIM cards or Wi-Fi plus cellular, into one tougher pipe. If one drops, the others carry on. Use it when streaming from a moving vehicle, through tunnels, or across dead zones where no single connection holds up.

StreamRelay supports both single-connection SRT and SRTLA bonding. So which one is right for you?

Streaming on solid 5G in a city, on Wi-Fi, or anywhere one connection stays stable? A plain SRT endpoint is simpler and enough, the same goes for drone feeds, encoder cameras, or a second OBS running over one good link. Moving through dead zones, tunnels, or a driving vehicle instead, where you need multiple connections to back each other up? That’s when SRTLA earns its keep. Either way you get a simple, GDPR-compliant EU relay without running your own server.

If a single solid connection covers what you do, SRT is simpler and saves you extra SIM cards and hardware. If your signal drops out mid-stream, SRTLA bonding keeps you live.

Why a German/EU relay matters

DE-CIX Frankfurt and low EU latency

Your endpoint is currently provisioned at DE-CIX Frankfurt, one of Europe’s largest internet exchanges, basically a giant junction where networks meet and hand off traffic. Other locations on request. Because it’s so well connected, EU streams take a short, direct route, which means lower latency (less delay) than bouncing your video through a server in the US first.

GDPR/DSGVO and your stream keys stay yours

The service is GDPR-compliant (GDPR/DSGVO is the EU’s strict data-protection law) and hosted in the EU. Your stream keys, the secret passwords that let you broadcast to your channel, never leave your control.

No port forwarding, no Linux server

You don’t have to open up your home network or rent and run your own server (a VPS). Both your phone and OBS simply reach out to the relay, the same way your browser reaches out to a website, so there’s nothing to expose or maintain on your end.

Common IRL streaming mistakes

Setting bitrate (how much data per second your video uses, higher means sharper but needs more signal) to match your best moment instead of your worst, that causes stutters the second your signal dips. Leave headroom.
Using RTMP on a flaky connection where SRT would have recovered better.
Forgetting an automatic “BRB” scene: set up NOALBS so OBS switches to a “be right back” screen on its own the moment your signal drops.
