SRT Streaming

Use SRT ingest for more resilient streaming on unreliable networks.

Overview

SRT is a UDP-based protocol with built-in recovery, ideal for mobile or long-haul networks. Meshcast accepts SRT ingest on registered accounts and routes it to WHEP or HLS playback.

Requirements

• Registered (free) Meshcast account or higher tier.
• SRT-capable encoder (OBS, Larix, Haivision Play, FFmpeg).
• UDP access to port 8890 on the assigned server.

Set up your SRT encoder

1. Copy your stream key Find your stream key and assigned server in the Meshcast dashboard or studio.
2. Build the SRT URL Use the publish stream ID format below (the publish: prefix is required).
   srt://[server-ip]:8890?streamid=publish:[stream-key]
3. Configure your encoder Set SRT mode to Caller, paste the URL above, and use a stable bitrate for the network.
4. Start streaming Publish and confirm the stream appears in your Meshcast dashboard or viewer link.

Playback options

• WHEP provides low-latency WebRTC playback for browsers.
• HLS is available for registered and paid tiers; free tier embeds are limited to meshcast.io and vdo.ninja domains.
• For VDO.Ninja playback, see IRL SRT to VDO.Ninja.
