## Usage

Please read guide [Getting Started](https://ossrs.io/lts/en-us/docs/v4/doc/getting-started) or [中文文档：起步](https://ossrs.net/lts/zh-cn/docs/v4/doc/getting-started).

To build SRS from source:

```
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
```

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)

Note that if convert RTMP to WebRTC, please use [`rtmp2rtc.conf`](https://github.com/ossrs/srs/issues/2728#issuecomment-964686152):

* H5(WebRTC): [webrtc://localhost/live/livestream](http://localhost:8080/players/rtc_player.html?autostart=true)

> Note: Besides of FFmpeg or OBS, it's also able to [publish by H5](http://localhost:8080/players/rtc_publisher.html?autostart=true) 
> if **WebRTC([CN](https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#rtc-to-rtmp), [EN](https://ossrs.io/lts/en-us/docs/v4/doc/webrtc#rtc-to-rtmp))** is enabled,
> please remember to set the **CANDIDATE([CN](https://ossrs.net/lts/zh-cn/docs/v4/doc/webrtc#config-candidate) or [EN](https://ossrs.io/lts/en-us/docs/v4/doc/webrtc#config-candidate))** for WebRTC.

> Highly recommend that directly run SRS by
> **docker([CN](https://ossrs.net/lts/zh-cn/docs/v4/doc/getting-started) / [EN](https://ossrs.io/lts/en-us/docs/v4/doc/getting-started))**,
> **Cloud Virtual Machine([CN](https://ossrs.net/lts/zh-cn/docs/v4/doc/getting-started-cloud) / [EN](https://ossrs.io/lts/en-us/docs/v4/doc/getting-started-cloud))**,
> or **K8s([CN](https://ossrs.net/lts/zh-cn/docs/v4/doc/getting-started-k8s) / [EN](https://ossrs.io/lts/en-us/docs/v4/doc/getting-started-k8s))**,
> however it's also easy to build SRS from source code, for detail please see
> **Getting Started([CN](https://ossrs.net/lts/zh-cn/docs/v4/doc/getting-started) / [EN](https://ossrs.io/lts/en-us/docs/v4/doc/getting-started))**.

> Note: If need HTTPS, by which WebRTC and modern browsers require, please read
> **HTTPS API([CN](https://ossrs.net/lts/zh-cn/docs/v4/doc/http-api#https-api) / [EN](https://ossrs.io/lts/en-us/docs/v4/doc/http-api#https-api))**
> and **HTTPS Callback([CN](https://ossrs.net/lts/zh-cn/docs/v4/doc/http-callback#https-callback) / [EN](https://ossrs.io/lts/en-us/docs/v4/doc/http-callback#https-callback))**
> and **HTTPS Live Streaming([CN](https://ossrs.io/lts/en-us/docs/v4/doc/delivery-http-flv#https-flv-live-stream) / [EN](https://ossrs.io/lts/en-us/docs/v4/doc/delivery-http-flv#https-flv-live-stream))**,
> however HTTPS proxy also works perfect with SRS such as Nginx.
