SRT Mini Server V2.6.6 (Reliable 16-Line Server)

Overview of SRT Mini Server

The SRT Mini Server is a lightweight, high-performance server application designed for secure, low-latency video and audio streaming across unreliable networks. Developed to meet the demands of modern media workflows, it is purpose-built to optimize streaming over the public internet using the SRT (Secure Reliable Transport) protocol.

What is the SRT Protocol?

SRT is an open-source video transport protocol. It handles packet loss and jitter better than traditional RTMP, ensuring a stable stream even on challenging connections. This is crucial for live broadcasts, remote contributions, and real-time data transfer.

Key Functionality of the 16 Lines Edition

The 16 Lines Edition denotes the server’s concurrency capacity, specifically its ability to handle up to 16 simultaneous connections or “lines.” This makes it the ideal choice for small to medium-sized production teams, educational environments, and single-channel broadcasters.

SRT Mini Server Installation Guide

This guide covers the standard installation for the SRT Mini Server V2.6.6 (Build 234).

Step 1: Download
Download the official installer package from the authorized vendor. Ensure you are downloading the correct version for your operating system.

Step 2: Run the Installer

• Windows: Double-click the .exe file. If prompted by User Account Control (UAC), click “Yes.”

• Linux: Extract the .tar.gz archive and run the binary file from the terminal.

Step 3: Installation Wizard

1. Read and accept the End-User License Agreement (EULA).

2. Choose the installation directory (default is usually C:\Program Files\SRT Mini Server).

3. Select the components to install. For a default setup, leave all options checked.

Step 4: Configure the “16 Lines” License
Once the installation is complete, the server will run in a trial mode or require a license key.

• Paid Version: Enter your provided license key in the server configuration panel to unlock the full 16-lines capacity.

• Free Version: A free edition is available but is typically limited to 2-4 lines, ideal for testing.

Step 5: Initial Start
Launch the application. The server will automatically start in the background. Access the web management UI at http://localhost:8080 (or the specified port) to begin configuration.

How to Use the SRT Mini Server

Once the server is running, the next step is to configure it to ingest a stream and send it to a destination.

Streaming Setup

1. Access the Administration Panel: Open a web browser and navigate to the server’s IP address (or localhost) on the assigned port (e.g., http://192.168.1.100:8080).

2. Add a Source (Input): Navigate to the “Sources” tab.

   • Select SRT Protocol.

   • Choose Connection Type: Listener, Caller, or Rendezvous.

   • Enter the IP Address and Port for the connection.

3. Configure Latency: Set the latency parameter in milliseconds. A setting of 1000ms is good for internet use, while 200ms is for high-quality LAN environments.

4. Add a Target (Output): Navigate to the “Targets” tab.

   • Enter the destination IP and Port for the receiving server or decoder (e.g., a cloud service or an OBS Studio instance).

5. Start Streaming: Once the source and target are configured, click the “Enable” or “Start” button. The server will begin routing the stream.

Best Use Cases for the 16 Lines Edition

The SRT Mini Server V2.6.6 (Build 234) is incredibly versatile. Here are the top scenarios where this server excels:

Comparison Table

Frequently Asked Questions (FAQ)

Q1: What is the difference between SRT and RTMP?
A: SRT (Secure Reliable Transport) is more resilient to packet loss and jitter compared to RTMP (Real-Time Messaging Protocol). SRT is preferred for streaming over the public internet, while RTMP is common for sending streams to content delivery networks.

Q2: Do I need a static IP address to use the SRT Mini Server?
A: It depends on the connection mode. In “Listener” mode, the server requires a publicly accessible static IP. In “Caller” mode, only the destination needs a static IP. “Rendezvous” mode can work behind NAT if configured correctly.

Q3: Can the SRT Mini Server run on a Raspberry Pi?
A: While possible for light loads, the Linux version of the SRT Mini Server is primarily designed for x86 architecture. Performance on an ARM-based Raspberry Pi may be limited.

Q4: Is the 16 Lines Edition good for a 24/7 broadcast channel?
A: Yes. The 16 Lines Edition supports up to 16 simultaneous connections, making it ideal for a single 24/7 channel that requires a backup source or multiple targets.

Q5: How do I fix “Connection Refused” errors?
A: This usually indicates a firewall block. Ensure the port used by the SRT Mini Server (default: 8080 or 5000 for SRT) is open on your router and Windows/Linux firewall.

Q6: What audio codecs are supported?
A: The server supports AAC (Advanced Audio Coding) and MPEG audio formats.

Q7: Is there a free version of the SRT Mini Server?
A: Yes. The vendor provides a free version, but it usually has restrictions on the number of connections or features compared to the 16 Lines Edition.

Q8: How much bandwidth do I need for an SRT stream?
A: Rule of thumb: your upload bandwidth should be at least double your output stream bitrate (e.g., a 5 Mbps stream requires at least 10 Mbps of stable internet).
