## Usage

Build SRS from source or **docker([CN](https://github.com/ossrs/srs/wiki/v4_CN_Home#docker) / [EN](https://github.com/ossrs/srs/wiki/v4_EN_Home#docker))**, please read **Wiki: Gettting Started([CN](https://github.com/ossrs/srs/wiki/v4_CN_Home#getting-started) / [EN](https://github.com/ossrs/srs/wiki/v4_EN_Home#getting-started))**:

```
git clone -b develop https://gitee.com/ossrs/srs.git &&
cd srs/trunk && ./configure && make && ./objs/srs -c conf/srs.conf
```

Open [http://localhost:8080/](http://localhost:8080/) to check it, then publish
by [FFmpeg](https://ffmpeg.org/download.html) or [OBS](https://obsproject.com/download) as:

```bash
ffmpeg -re -i ./doc/source.flv -c copy -f flv -y rtmp://localhost/live/livestream
```

> Note: It's also able to [publish by H5](http://localhost:8080/players/rtc_publisher.html?autostart=true) if WebRTC is enabled.

Play the following streams by [players](https://ossrs.net):

* RTMP (by [VLC](https://www.videolan.org/)): 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)
