Simple-RTMP-Server
==================
SRS(SIMPLE RTMP Server) over state-threads created in 2013.
SRS is a simple, RTMP/HLS, high-performance, single/multiple(plan) processes, edge(plan)/origin live server.
SRS supports [vhost](https://github.com/winlinvip/simple-rtmp-server/wiki/RtmpUrlVhost), rtmp(encoder push, client/edge pull), ingester(srs pull), [HLS](https://github.com/winlinvip/simple-rtmp-server/wiki/DeliveryHLS), [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).

### Architecture
System Architecture:
+------------------------------------------------------+
| SRS(Simple RTMP Server) |
+---------------+---------------+-----------+----------+
| API/hook | Transcoder | HLS | RTMP |
| http-parser | FFMPEG/x264 | NGINX/ts | protocol |
+---------------+---------------+-----------+----------+
| Network(state-threads) |
+------------------------------------------------------+
| All Linux(RHEL,CentOS,Ubuntu,Fedora...) |
+------------------------------------------------------+
Modularity Architecture:
+------------------------------------------------------+
| Main(srs/bandwidth/librtmp) |
+------------------------------------------------------+
| App(Server/Client application) |
+------------------------------------------------------+
| RTMP(Protocol stack) |
+------------------------------------------------------+
| Kernel(depends on Core, provides error/log) |
+------------------------------------------------------+
| Core(depends only on system apis) |
+------------------------------------------------------+
Stream Architecture:
+---------+ +----------+
+ Publish + + Deliver |
+---|-----+ +----|-----+
+------------------+-------------------------+----------------+
| Input | SRS(Simple RTMP Server) | Output |
+------------------+-------------------------+----------------+
| Encoder(1) | +-> RTMP protocol ----+-> Flash Player |
| (FMLE,FFMPEG, --+->-+-> HLS/NGINX --------+-> m3u8 player |
| Flash,XSPLIT, | +-> Fowarder ---------+-> RTMP Server |
| ......) | +-> Transcoder -------+-> RTMP Server |
| | +-> DVR --------------+-> FILE |
| | +-> BandwidthTest ----+-> Flash/StLoad |
+------------------+ | |
| MediaSource(2) | | |
| (RTSP,FILE, | | |
| HTTP,HLS, --+->-- Ingester -----------+-> SRS |
| Device, | | |
| ......) | | |
+------------------+-------------------------+----------------+
Remark:
(1) Encoder: encoder must push RTMP stream to SRS server.
(2) MediaSource: any media source, which can be ingest by ffmpeg.
(plan) RTMP cluster(origin/edge) Architecture:
Remark: cluster over forward, see [Cluster](https://github.com/winlinvip/simple-rtmp-server/wiki/Cluster)
+---------+ +-----------------+ +-----------------------+
+ Encoder +--+-->-+ SRS(RTMP Edge) +--->-+ (RTMP Origin) |
+---------+ | +-----------------+ | SRS/FMS/NGINX-RTMP |
| | Red5/HELIX/CRTMP |
+-------------------------->-+ ...... |
+-----------------------+
Schema#1: Any RTMP encoder push RTMP stream to RTMP (origin/edge)server,
where SRS RTMP Edge server will forward stream to origin.
+-------------+ +-----------------+ +--------------------+
| RTMP Origin +-->-+ SRS(RTMP Edge) +--+->-+ Client(RTMP/HLS) |
+-------------+ +-----------------+ | | Flash/IOS/Android |
| +--------------------+
|
| +-----------------+
+->-+ SRS(RTMP Edge) +
+-----------------+
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--->-----+
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.
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.
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.
