### What is SRT?

SRT stands for Secure Reliable Transport and it is a protocol for transmitting high-quality video over unreliable networks, such as the internet. It is an open-source protocol that uses encryption and error correction to ensure that video and audio streams are delivered reliably and securely, even in low-bandwidth or congested network conditions. SRT is commonly used in live video streaming applications, such as sports broadcasting, where a high-quality, low-latency video feed is critical.

### SRT and mimoLive

Thanks to FFmpeg, mimoLive can now offer SRT (Secure Reliable Transport) ingest support starting with version 6.0. Find more information on SRT at the [SRT web site](https://www.srtalliance.org/).

> **Important:** This is preliminary documentation and we do not have extensive experience with SRT. Please let us know if you find any issues.

### Setting up mimoLive as an SRT receiver

Create an [FFmpeg source](https://mimolive.com/user-manual/ffmpeg) and enter these parameters into the FFmpeg Input Parameter field:

```
-i srt://xxx.xxx.xxx.xxx:9998?pkt_size=1316&mode=listener
```

replacing the “xxx.xxx.xxx.xxx” with the **local** IP number of your Mac.

> **Important:** Your network needs to be configured so that the Mac you’re running on is reachable from the Internet via a public IP number and the port 9998.

### Sending SRT to mimoLive

In order to test the setup, you can also use ffmpeg to send a test signal to your SRT receiver. You should have a video file on your remote computer and ffmpeg installed. Then you can open the Terminal and issue this command:

```
ffmpeg -i testmovie.mp4 -acodec copy -vcodec copy -f mpegts srt://yyy.yyy.yyy.yyy:9998?pkt_size=1316
```

where you need to replace “yyy.yyy.yyy.yyy” with the **public** IP number where your mimoLive Mac is reachable. This is most likely different from the local IP number.
