## Why SRS?
1. We completely rewrote HLS following m3u8/ts spec, and HLS support h.264+aac/mp3.
1. Highly efficient RTMP streaming, supporting 7k+ clients concurrency, vhost based, both origin and edge.
1. Embedded simplified media HTTP server for HLS, api and HTTP flv/ts/mp3/aac streaming.
1. Variety input: RTMP, pull by ingest file or stream(HTTP/RTMP/RTSP), push by stream caster
RTSP/MPEGTS-over-UDP.
1. Popular internet delivery: RTMP/HDS for flash, HLS for mobile(IOS/IPad/MAC/Android), HTTP
flv/ts/mp3/aac streaming for user prefered.
1. Enhanced DVR and hstrs: segment/session/append plan, customer path and HTTP callback.
the hstrs(http stream trigger rtmp source) enable the http-flv stream standby util encoder
start publish, similar to rtmp, which will trigger edge to fetch from origin.
1. Multiple feature: transcode, forward, ingest, http hooks, dvr, hls, rtsp, http streaming,
http api, refer, log, bandwith test and srs-librtmp.
1. Best maintainess: simple arch over state-threads(coroutine), single thread, single process
and for linux/osx platform, common server x86-64/i386/arm/mips cpus, rich comments, strictly
follows RTMP/HLS/RTSP spec.
1. Easy to use: both English and Chinese wiki, typically config files in trunk/conf, traceable
and session based log, linux service script and install script.
1. MIT license, open source with product management and evolution.
Enjoy it!
## About
SRS(Simple RTMP Server) over state-threads created on 2013.10.
SRS delivers rtmp/hls/http/hds live on x86/x64/arm/mips linux/osx,
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,
with stream caster to push MPEGTS-over-UDP/RTSP to SRS,
provides EN/CN wiki and the most simple architecture.

We use FMLE as encoder for benchmark. The latency of server is 0.1s+,
and the bottleneck is the encoder. For more information, read
[bug #257][bug #257-c0].
### HLS overhead
About the HLS overhead of SRS, we compare the overhead to FLV by remux the HLS to FLV by ffmpeg.
| Bitrate | Duration | FLV(KB) | HLS(KB) | Overhead |
| ------- | -------- | ------- | -------- | --------- |
| 275kbps | 600s | 11144 | 12756 | 14.46% |
| 260kbps | 1860s | 59344 | 68004 | 14.59% |
| 697kbps | 60s | 5116 | 5476 | 7.03% |
| 565kbps | 453s | 31316 | 33544 | 7.11% |
| 565kbps | 1813s | 125224 | 134140 | 7.12% |
| 861kbps | 497s | 52316 | 54924 | 4.98% |
| 857kbps | 1862s | 195008 | 204768 | 5.00% |
| 1301kbps | 505s | 80320 | 83676 | 4.17% |
| 1312kbps | 1915s | 306920 | 319680 | 4.15% |
| 2707kbps | 600s | 198356 | 204560 | 3.12% |
| 2814kbps | 1800s | 618456 | 637660 | 3.10% |
| 2828kbps | 60s | 20716 | 21356 | 3.08% |
| 2599kbps | 307s | 97580 | 100672 | 3.16% |
| 2640kbps | 1283s | 413880 | 426912 | 3.14% |
| 5254kbps | 71s | 45832 | 47056 | 2.67% |
| 5147kbps | 370s | 195040 | 200280 | 2.68% |
| 5158kbps | 1327s | 835664 | 858092 | 2.68% |
The HLS overhead is calc by: (HLS - FLV) / FLV * 100%.
The overhead is larger than this benchmark(48kbps audio is best overhead), for we fix the [#512][bug #512].
## 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.
### System Architecture
+------------------------------------------------------+
| SRS(Simple RTMP Server) |
+---------------+---------------+-----------+----------+
| API/hook | Transcoder | HLS/HDS | RTMP/FLV |
| http-parser | FFMPEG/x264 | NGINX/ts | protocol |
+---------------+---------------+-----------+----------+
| Network(state-threads) |
+------------------------------------------------------+
| All Linux/Unix(RHEL,CentOS,Ubuntu,Fedora...) |
+------------------------------------------------------+
### Modularity Architecture
+------------------------------------------------------+
| Main(srs/ingest-hls/librtmp) |
+------------------------------------------------------+
| App(Server/Client application) |
+------------------------------------------------------+
| RTMP/HTTP/RawStream(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/HDS --------+-> Flash player |
| (FMLE,FFMPEG, -rtmp-+->-+-> HLS/HTTP ---------+-> M3u8 player |
| Flash,XSPLIT, | +-> FLV/MP3/Aac/Ts ---+-> HTTP player |
| ......) | +-> Fowarder ---------+-> RTMP server |
| | +-> Transcoder -------+-> RTMP server |
| | +-> DVR --------------+-> Flv file |
| | +-> BandwidthTest ----+-> flash |
+----------------------+ | |
| MediaSource(2) | | |
| (RTSP,FILE, | | |
| HTTP,HLS, --pull-+->-- Ingester(3) -(rtmp)-+-> SRS |
| Device, | | |
| ......) | | |
+----------------------+ | |
| MediaSource(2) | | |
| (RTSP,FILE, | | |
| HTTP,HLS, --push-+->-- Streamer(4) -(rtmp)-+-> SRS |
| Device, | | |
| ......) | | |
+----------------------+-------------------------+----------------+
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. Read Ingest.
(4) Streamer: SRS will listen for some protocol and accept stream push
over some protocol and remux to rtmp to SRS. Read Streamer.
