-_rtsp-simple-server_ is a simple, ready-to-use and zero-dependency RTSP server, a software that allows multiple users to read or publish 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 and read or write data. The server is then responsible of linking the publisher stream with the readers.

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).

 #### 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.

-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:
