IRL streaming, explained clearly
irl4you.de collects practical information on mobile livestreams: from SRT and SRTLA through RTMP, RIST and LRT™ to Moblin, OBS Studio, relay servers, cameras, routers and cellular networks.
For stable outdoor streams, the camera is only part of the picture. Transport protocol, encoder, the internet connections you have and the path from the mobile device through a relay server to the target platform matter just as much.
New on IRL4YOU
The latest guides and additions at a glance.
Two auto-installers for SRTLA and RTMP
Set up on Debian and Ubuntu and tested with a real video stream. The new blog post shows both routes, their limits and the shared practice video.
Network overlay right in the video
Show active connections, custom names and colors, plus total bandwidth and RTT, right in the BELABOX stream. It comes with a local configurator and a tested install package.
Practice, planning and quick help
These guides take you from the last tech check before the stream to troubleshooting on the road.
Interactive IRL Setup Finder
Match smartphone, hardware encoder, protocol, relay, OBS, network paths and extra features to a signal path that fits.
Audio Set up your audio properly
Connect microphone, Bluetooth speaker, headphones, alerts and OBS without echo or doubled output.
Checklist Check before you start
Tick off gear, cellular, OBS, alerts, GPS, moderation and emergency scenes interactively.
Calculator Data and runtime
Calculate data usage, recording size and rough power bank runtime right in your browser.
Help Find stream errors
Work through no picture, blocky video, dropouts or missing audio step by step along the signal chain.
BELABOX Complete setup
Plan camera, audio, modems, bonding, target server, power supply, cooling and Remote UI.
Alerts Compare solutions
Classic alerts, sounds, TTS, channel points and mobile output, each pointing you to the matching guide.
Community Chat and moderation
Organize moderators, TTS, filters, channel points, an emergency contact and the protection of private information.
Security Protected on the road
Take location, home, license plates, people, keys, tokens and emergency scenes into account.
Glossary Understand the terms
Bitrate, bonding, codec, latency, relay, RTMP, SRTLA, RIST, VPS and WebSocket explained simply.
Creator practice Imprint service
Learn the key checkpoints for an imprint and get a factual take on the RAHFT imprint service for creators.
Streaming hardware
Hardware IRL backpack & cameras
Camera, encoder, power supply and network together make up a portable IRL setup.
Hardware Routers & modems
Mobile routers, modems and several independent internet connections make you more resilient to outages on the road.
Streaming software & infrastructure
Open Beta IRLwhatever
IRLwhatever is a new Android app that captures camera and audio, encodes the livestream and sends it over SRTLA, RIST, SRT or RTMP to a destination you've set up.
Software Moblin
Moblin suits mobile IRL workflows straight from your smartphone and can combine camera, audio and streaming functions in one compact setup.
Android IRL Pro
Set up IRL Pro for mobile Android streams with RTMP, SRT, SRTLA bonding, adaptive bitrate, chat, web overlays and a relay server.
Android pocketSRT & pocketBond
pocketSRT takes RTMP from an action cam or OBS and forwards the stream over SRT or SRTLA. pocketBond adds more Android phones as mobile data paths.
Stream companion pocketChat
pocketChat brings chat, moderation, TTS, alerts, OBS control and BELABOX status together on Android, iOS and in the browser.
Software OBS Studio
OBS Studio can receive the mobile stream in one place, combine scenes, overlays and audio, and send the finished signal to the target platform.
Overlay GPS map in your stream
Compare StreamerHub without an RTIRL key and RealtimeIRL, and show the map, speed, route, altitude and other location data in OBS.
Automation NOALBS
NOALBS watches the bitrate at the RTMP, SRT or SRTLA relay and automatically switches OBS to a prepared fallback scene when the signal is poor or missing.
Alerts Stream alerts on the go
Show follows, subs, gift subs, bits, raids and donations in OBS and play them back to the IRL streamer over a Bluetooth speaker or headphones.
Automation Streamer.bot
Automation hub for alerts and OBS. With the web-based Streamer.bot Deck, you can trigger prepared functions from your smartphone or tablet on the road, normally without open router ports.
Server Redefined relay server
A professional Redefined relay server is the stable middle station for high-quality SRT and SRTLA streams and helps reduce visible transmission errors.
Streaming protocols
Protocol SRTLA (SRT + bonding)
SRTLA combines an SRT-based transport with the use of several network paths and is especially interesting for mobile IRL setups.
- Advantage: several connections for a sturdier uplink
- Networks: LTE, 5G, Wi-Fi and other IP connections
- Use: IRL backpacks, mobile encoders and bonding servers
Protocol LRT™ (LiveU Reliable Transport)
LRT™ is LiveU's transport protocol for reliable live video transmission and mobile multi-link workflows.
- Advantage: built for difficult network conditions
- Bonding: several IP connections in LiveU workflows
- Use: LiveU encoders, mobile streaming and broadcast
Protocol SRT (Secure Reliable Transport)
SRT is designed for reliable video transmission over fluctuating or lossy connections.
- Advantage: stays stable despite packet loss and a fluctuating connection
- Features: retransmission requests and configurable latency
- Use: encoders, relay servers and mobile video transport
Protocol RTMP / RTMPS
RTMP is still widely used to send a finished livestream to platforms or streaming servers. RTMPS protects the connection with TLS.
- Advantage: broad compatibility
- Software: OBS and many encoders
- Use: output from the production system to the target platform
Protocol RIST
RIST is an open approach to reliable professional video transport over IP networks and aims at interoperability between systems.
- Advantage: professional, interoperable IP transport
- Use: broadcast and video transport infrastructure
Protocol NDI™ (Network Device Interface)
NDI™ carries video, audio and metadata with low delay inside a local production network.
- Advantage: fast transfer between compatible devices
- Network: controlled LAN or powerful Wi-Fi
- Use: local camera sources, production computers and OBS
NDI™ is a trademark of Vizrt NDI AB.
