_rtsp-simple-server_ is a simple, ready-to-use and zero-dependency RTSP server, a program that allows multiple users to read or publish live video and audio streams. RTSP a standardized protocol that defines how to perform these operations with the help of a server, that is contacted by both readers and publishers in order to negotiate a streaming protocol and read or write data. The server is then responsible of linking the publisher stream with the readers.

This software was developed with the aim of simulating a live camera feed for debugging purposes, and therefore to use files instead of real streams. Another reason for the development was the deprecation of _FFserver_, the component of the FFmpeg project that allowed to create a RTSP server with _FFmpeg_ (but this server can be used with any software that supports RTSP).

Features:
* Supports reading and publishing streams
* Supports one publisher at once, while readers can be more than one
* Supports reading via UDP and TCP
* Supports publishing via UDP and TCP

## Installation

Precompiled binaries are available in the [release](https://github.com/aler9/rtsp-simple-server/releases) page. Just download and extract the executable.


<br />

## Usage

1. Start the server:
   ```
   ./rtsp-simple-server
   ```

2. In another terminal, publish something with FFmpeg (in this example it's a video file, but it can be anything you want):
   ```
   ffmpeg -re -stream_loop -1 -i file.ts -map 0:v:0 -c:v copy -f rtsp rtsp://localhost:8554/
   ```

3. Open the stream with VLC:
   ```
   vlc rtsp://localhost:8554/
   ```

   you can alternatively use GStreamer:
   ```
   gst-launch-1.0 -v rtspsrc location=rtsp://localhost:8554/ ! rtph264depay ! decodebin ! autovideosink
   ```
