SRS is a simple, [RTMP](https://github.com/winlinvip/simple-rtmp-server/wiki/DeliveryRTMP)/[HLS](https://github.com/winlinvip/simple-rtmp-server/wiki/DeliveryHLS), [high-performance](https://github.com/winlinvip/simple-rtmp-server/wiki/Performance), single/multiple(plan) processes, edge/origin live server, [x86/x64/arm](https://github.com/winlinvip/simple-rtmp-server/wiki/SrsLinuxArm), compile depends on [st](http://sourceforge.net/projects/state-threads)(required), [ssl](http://www.openssl.org/) and [http-parser](https://github.com/joyent/http-parser), use [nginx](http://nginx.org/), [ffmpeg](http://ffmpeg.org/) and [cherrypy](http://www.cherrypy.org/) as external tools. that is, only need st to run srs for minimum run. see [Build](https://github.com/winlinvip/simple-rtmp-server/wiki/Build). SRS supports [vhost](https://github.com/winlinvip/simple-rtmp-server/wiki/RtmpUrlVhost), rtmp([encoder push](https://github.com/winlinvip/simple-rtmp-server/wiki/DeliveryRTMP), client/[edge](https://github.com/winlinvip/simple-rtmp-server/wiki/Edge) pull), [ingester(srs pull)](https://github.com/winlinvip/simple-rtmp-server/wiki/Ingest), [HLS](https://github.com/winlinvip/simple-rtmp-server/wiki/DeliveryHLS), [HLS audio only](https://github.com/winlinvip/simple-rtmp-server/wiki/DeliveryHLS#hlsaudioonly), [transcoding](https://github.com/winlinvip/simple-rtmp-server/wiki/FFMPEG), [forward](https://github.com/winlinvip/simple-rtmp-server/wiki/FFMPEG), [http hooks](https://github.com/winlinvip/simple-rtmp-server/wiki/HTTPCallback), [http api](https://github.com/winlinvip/simple-rtmp-server/wiki/HTTPApi), [http server](https://github.com/winlinvip/simple-rtmp-server/wiki/HTTPServer), [dvr](https://github.com/winlinvip/simple-rtmp-server/wiki/DVR), [FlashP2P](https://github.com/winlinvip/simple-rtmp-server/wiki/FlashP2P). 注意：FlashP2P系统为[chnvideo.com](http://www.chnvideo.com)商业方案，SRS只是支持对接。 Release: [http://winlinvip.github.io/simple-rtmp-server](http://winlinvip.github.io/simple-rtmp-server)

Remark:
(1) Encoder: encoder must push RTMP stream to SRS server.
(2) MediaSource: any media source, which can be ingest by ffmpeg.
(3) Ingester: SRS will fork a process to run ffmpeg(or your application) 
to ingest any input to rtmp, push to SRS.

                                          +-----------------------+ 
Schema#1: Any RTMP encoder push RTMP stream to RTMP (origin/edge)server,
    where SRS RTMP Edge server will forward stream to origin.

                                            +-----------------+
Schema#2: SRS RTMP Edge server pull stream from origin (or upstream SRS 
    RTMP Edge server), then delivery to Client.
### (plan) SRS Multiple processes Architecture(design by wenjie) 
                 +---------------+              +--------+
                 | upnode server |              + client +

            -------------+------------network-------+---------
                         |                          |
 +--------+         +----+-----------+         +----+----------+
 | master +--fork->-+ back source(1) +-->-pull-+ stream 1-N(2) +
 +---+----+         +----------------+         +-------+-------+
     |                                                 |
     +-------------------------------------fork--->-----+
     |                           +-------------+
     +-------------------fork-->-+ http/vod(3) |
                                 +-------------+
Remark:
(1) back source process: create by master process, get stream from 
    upnode server if edge, create stream if origin, serve the stream 
    process.
(2) stream process: create by master process, get stream from back
    source process, serve the client.
(3) the embeded mininum http server, also provides vod service. for
    http server, it provides http api, hls(live/vod) delivery. for
    vod server, it slice the file to hls(m3u8/ts).
Remark:
(a) This multiple processes architecture is design by wenjie, it's a
    very simple and powerful multiple process architecture, for the
    master no need to pass between stream process.
(b) The CLI architecture is similar to this, instead, cli process
    will collect informations from all stream process, master process
    only send signals to child processes.
### (plan) CLI Architecture 
                       +---------+
                    +--+ stream1 +---------+
                    |  +---------+         |

 | master +--fork->-+--+ streamN +---amf0--+>--+  cli  +
 +--------+         |  +---------+         |   +-------+
                    |  +-------------+     |
                    +--+ back source +-----+
                       +-------------+
Remark:
(1) master listen the global api port, for example, 33330
(2) back source and stream processes listen at private api port, 
    for example, 33331, 33332, 33333
(3) work processes(stream and back-source), report private api
    port to master global api port.
(4) cli connect to master global api port, get all other private
    api ports
(5) cli connect to each stream/back-source process to get api data,
    cli analysis and summary the data, return to user.
