-_rtsp-simple-server_ is a simple, ready-to-use and zero-dependency RTSP server, a software that allows multiple users to publish and read live video and audio streams. RTSP is 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. The server is then responsible of relaying the publisher stream to 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 (but this server is not bounded to _FFmpeg_ and can be used with any software that supports publishing to RTSP).

-_rtsp-simple-server_ is an RTSP server: it publishes existing streams and does not touch them. It is not a media server, that is a far more complex software that can receive existing streams, re-encode them and publish them. Therefore, _rtsp-simple-server_ alone cannot change the format, codec or compression of a stream.

-Nothing forbids from using _FFmpeg_ or _Gstreamer_ together with _rtsp-simple-server_, obtaining the same features of a media server. For instance, if we want to re-encode an existing stream, that is available in the `/original` path, and make the modified stream available in the `/compressed` path, it is enough to launch _FFmpeg_ in parallel with _rtsp-simple-server_, with the following syntax:
