## Usage
Recommend to run SRS by [docker][docker-srs4]:
```bash
docker run --rm -p 1935:1935 -p 1985:1985 -p 8080:8080 \
ossrs/srs:v4.0.76
# Or, for developers in China to speedup.
docker run --rm -p 1935:1935 -p 1985:1985 -p 8080:8080 \
registry.cn-hangzhou.aliyuncs.com/ossrs/srs:v4.0.76
# For macOS to enable WebRTC, other OS please see #307.
docker run --rm -p 1935:1935 -p 1985:1985 -p 8080:8080 \
--env CANDIDATE=$(ifconfig en0 inet| grep 'inet '|awk '{print $2}') -p 8000:8000/udp \
registry.cn-hangzhou.aliyuncs.com/ossrs/srs:v4.0.76
```
> Note: All [tags](https://github.com/ossrs/srs/tags) are available, such as
> `ossrs/srs:v3.0-r3` for tag [v3.0-r3](https://github.com/ossrs/srs/releases/tag/v3.0-r3),
> please check at [here](https://cr.console.aliyun.com/repository/cn-hangzhou/ossrs/srs/images)
> or [there](https://hub.docker.com/r/ossrs/srs/tags).
> To enable WebRTC, user MUST set the env `CANDIDATE`, see [#307](https://github.com/ossrs/srs/issues/307#issue-76908382).
If it works, open [http://localhost:8080/](http://localhost:8080/) to check it, then publish
[stream](https://github.com/ossrs/srs/blob/3.0release/trunk/doc/source.200kbps.768x320.flv) by:
```bash
ffmpeg -re -i doc/source.200kbps.768x320.flv -c copy \
-f flv rtmp://localhost/live/livestream
# Or by FFmpeg docker
docker run --rm --network=host registry.cn-hangzhou.aliyuncs.com/ossrs/srs:encoder \
ffmpeg -re -i ./doc/source.200kbps.768x320.flv -c copy \
-f flv -y rtmp://localhost/live/livestream
```
> Note: If WebRTC enabled, you can publish by [H5](http://localhost:8080/players/rtc_publisher.html?autostart=true).
Play the following streams by players:
* VLC(RTMP): rtmp://localhost/live/livestream
* H5(HTTP-FLV): [http://localhost:8080/live/livestream.flv](http://localhost:8080/players/srs_player.html?autostart=true&stream=livestream.flv&port=8080&schema=http)
* H5(HLS): [http://localhost:8080/live/livestream.m3u8](http://localhost:8080/players/srs_player.html?autostart=true&stream=livestream.m3u8&port=8080&schema=http)
* H5(WebRTC): [webrtc://localhost/live/livestream](http://localhost:8080/players/rtc_player.html?autostart=true)
> The online demos and players are available on [ossrs.net](https://ossrs.net).

It's also very easy to build from source:
**>>> Step 1:** Get SRS.
```
git clone https://gitee.com/winlinvip/srs.oschina.git srs &&
cd srs/trunk && git remote set-url origin https://github.com/ossrs/srs.git &&
git checkout 4.0release && git pull
```
> Note: We use [mirrors(gitee)](#mirrors) here, but it's also ok to directly clone by `git clone https://github.com/ossrs/srs.git && cd srs/trunk`
**>>> Step 2:** Build SRS.
```
./configure && make
```
> Remark: Recommend to use Centos7 64bits, please read wiki([CN][v3_CN_Build],[EN][v3_EN_Build]).
> Note: You can also build SRS in docker, please read [docker][docker-dev].
**>>> Step 3:** Run SRS
```
./objs/srs -c conf/srs.conf
```

Remark:
1. Concurrency: We only benchmark the concurrency of single process.
1. MultipleProcess: SRS supports multiple processes by [go-oryx][oryx].
1. HLS aonly: HLS supports audio only mode without video stream.
1. BW check: The bandwidth check feature is used to detect the bandwidth between server and client.
1. Security: The security includes access control, token authentication and referer check.
1. Reload: SRS and Nginx supports reload, but nginx-rtmp doesn't.

We used FMLE as encoder for benchmark. The latency of server was 0.1s+,
and the bottleneck was the encoder. For more information, read

**HLS overhead**
About the overhead of HLS overhead, we compared FFMPEG and SRS.
| 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 should be larger than this benchmark(48kbps audio is best overhead), for we fix the [#512][bug #512].
## Architecture
SRS always use the simplest architecture to solve complex domain problems.
* System arch: the system structure and arch.
* Modularity arch: the main modularity of SRS.
* Stream arch: the stream dispatch arch of SRS.

Remark:
1. Encoder: Encoder pushs RTMP stream to SRS.
1. MediaSource: Supports any media source, ingesting by ffmpeg.
1. Ingester: Forks a ffmpeg(or other tools) to ingest as rtmp to SRS, please read [Ingest][v1_CN_Ingest].
1. Streamer: Remuxs other protocols to RTMP, please read [Streamer][v2_CN_Streamer].
1. EXEC: Like NGINX-RTMP, EXEC forks external tools for events, please read [ng-exec][v3_CN_NgExec].
1. SRTModule: A isolate module which run in [hybrid](https://github.com/ossrs/srs/issues/1147#issuecomment-577574883) model.
