_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.

The server is then responsible of relaying the publisher streams 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).

#### Remuxing, re-encoding, compression
_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.
_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 and heavy software that can receive existing streams, re-encode them and publish them.
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:
