## About

SRS(SIMPLE RTMP Server) over state-threads created in 2013.10.

SRS delivers rtmp/hls live on x86/x64/arm/mips linux, 
supports origin/edge/vhost and transcode/ingest and dvr/forward 
and http-api/http-callback/reload, introduces tracable 
session-oriented log, exports client srs-librtmp, 
provides EN/CN wiki and the most simple architecture.

SRS focus on small problem domain, which is the most complex for all software(see OOAD). 
Because of lack of deveoper resource, SRS only provides features which is the most popular 
for internet. SRS is simple for and only for problem domain is simplified.

SRS is a simple, RTMP(

## Architecture

SRS always use the most simple architecture to support complex transaction.
* System arch: the system structure and arch.
* Modularity arch: the main modularity of SRS.
* Stream arch: the stream dispatch arch of SRS.
* RTMP cluster arch: the RTMP origin and edge cluster arch.
* Multiple processes arch (by wenjie): the multiple process of SRS.
* CLI arch: the cli arch for SRS, api to manage SRS.
* Bandwidth specification: the bandwidth test specification of SRS.

### Modularity Architecture

+----------------------+-------------------------+----------------+

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.

    RTMP Edge server), then delivery to Client.
