How to Set Up SRTLA with Moblin and IRLHost
IRLHost stabilises your mobile connection using SRT/SRTLA. OBS receives the clean stream and sends it to your platform. Your stream key goes in OBS — not in IRLHost.
What You Need
- iPhone with Moblin installed
- A computer at home running OBS (almost any modern PC or Mac works)
- An IRLHost relay server
- A data connection (mobile or WiFi)
Step 1: Create Your Relay Server on IRLHost
Log in to your IRLHost dashboard at irlhost.gg. Create a new relay server and note down your SRT ingest URL and stream key.
Step 2: Set Up OBS on Your Home PC
Open OBS on your home computer. Go to Settings → Stream and configure your Twitch or Kick stream key there as normal.
In your OBS scene, add a Media Source pointing to your IRLHost relay SRT ingest URL. This is how OBS receives the stabilised stream from your phone.
Step 3: Configure Moblin on Your iPhone
Open Moblin. Tap the settings icon and navigate to Stream. Select SRT or SRTLA as your streaming protocol. Enter your IRLHost details:
- URL: Your IRLHost relay SRT ingest URL
- Stream ID: Your IRLHost stream key
- Latency: 2000ms is a good starting point
Step 4: Enable SRTLA Bonding (Recommended)
Moblin supports SRTLA natively. In stream settings, enable bonding and add your available connections — WiFi and cellular. SRTLA combines both for maximum stability. IRLHost handles the bonding on the server side, so your stream keeps going even if one connection drops.
Step 5: Go Live
Start streaming in Moblin, verify OBS is receiving the feed, then go live in OBS. Check your IRLHost dashboard to monitor bitrate and connection health.
Troubleshooting
OBS not receiving stream: Double-check your IRLHost SRT ingest URL in the OBS Media Source settings. Make sure your IRLHost server status shows "RUNNING" in the dashboard.
Low bitrate / drops in Moblin: Try increasing latency to 3000-4000ms in poor signal areas. Enable SRTLA bonding if you have both WiFi and mobile data available.
High latency: Choose the IRLHost server region closest to your physical location.
