## Usage

**>>> 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 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
```

**>>> Whatever**, you can also directly run SRS in [docker][docker-srs3]:

```
docker run -p 1935:1935 -p 1985:1985 -p 8080:8080 \
    registry.cn-hangzhou.aliyuncs.com/ossrs/srs:3
```

> Note: Again, we use [ACR](https://cr.console.aliyun.com/) here, you can directly run in docker hub by `docker run -p 1935:1935 -p 1985:1985 -p 8080:8080 ossrs/srs:3`

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.

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.
