Mistserver is a lightweight, open-source multistandard multimedia streaming server. It bridges the gap between lightweight webservers and the usually heavyweight mediaservers that support non-HTTP protocols.
Design Principles 
Mistservers main design concept is modularity. The server software was designed from the ground up to be modular in respect to supported protocols and encodings, so that new advances in these fields could easily and quickly be added to the server without having to redesign or rewrite any parts of it. Every connected user starts up a new process on the server. This effectively means that if somehow a viewer manages to crash the server process, only that viewers' connection will be affected. All other viewers will be able to keep using the server unimpaired. This additionally means that Connectors that are not currently in use do not require system resources, and problems with one Connector will not be able to affect the others.
Inside the server 
The Controller process is the "core" of Mistserver. It is the process that provides the API as well as spawns, monitors and communicates with Buffers and Connectors.
Connectors are a terminology used in Mistserver. They are processes that listen on their supported protocol port(s) for incoming connections, then handling that connection in their native protocol. Usually this involves figuring out the requested stream name, connecting to the relevant Buffer or Player process through a Unix Domain Socket, then sending the stream data through after conversion to the proper container format.
The suite of converter applications allows you to convert several media containers (FLV, TS) to and from DTSC format.
Analysers are tools included with Mistserver that can be useful for analyzing and/or manipulating several types of media-related files.
