```

Arguments of '-H' are forwarded to option
[`listening_ports`](https://github.com/civetweb/civetweb/blob/master/docs/UserManual.md#listening_ports-8080)
of civetweb, allowing use of the civetweb syntax like `-H8000,9000` or
`-H8080r,8443s`.

Using `-o` allows storing compressed frame data from the backend stream using
`webrtc::VideoFrameBuffer::Type::kNative`. This hacks the stucture
`webrtc::VideoFrameBuffer` storing data in a override of the i420 buffer. This
allows forwarding H264 frames from V4L2 device or RTSP stream to WebRTC stream.
It uses less CPU, but has less features (resize, codec, and bandwidth are
disabled).

Options for the WebRTC stream name:

- an alias defined using `-n` argument then the corresponding `-u` argument will
  be used to create the capturer
- an "rtsp://" url that will be opened using an RTSP capturer based on live555
- an "file://" url that will be opened using an MKV capturer based on live555
- an "rmtp://" url that will be opened using an RMTP capturer based on librmtp
- an "screen://" url that will be opened by
  `webrtc::DesktopCapturer::CreateScreenCapturer`
- an "window://" url that will be opened by
  `webrtc::DesktopCapturer::CreateWindowCapturer`
- an "v4l2://" url that will capture
  [H264](https://en.wikipedia.org/wiki/Advanced_Video_Coding) frames and store
  it using webrtc::VideoFrameBuffer::Type::kNative type (not supported on
  Windows)
- an "videocap://" url video capture device name
- an "audiocap://" url audio capture device name

#### Examples

```sh
./webrtc-streamer -C config.json
```

[Live Demo](https://webrtc-streamer-mpromonet.cloud.okteto.net/)

We can access to the WebRTC stream using
[webrtcstreamer.html](https://github.com/mpromonet/webrtc-streamer-html/blob/master/webrtcstreamer.html).
For instance:

- [webrtcstreamer.html?rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov](https://webrtc-streamer-mpromonet.cloud.okteto.net/webrtcstreamer.html?rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov)
- [webrtcstreamer.html?Bunny](https://webrtc-streamer-mpromonet.cloud.okteto.net/webrtcstreamer.html?Bunny)

An example displaying grid of WebRTC Streams is available using option
`layout=<lines>x<columns>`
[![Screenshot](images/layout2x4.png)](https://webrtc-streamer-mpromonet.cloud.okteto.net/?layout=2x4)

[Live Demo](https://webrtc-streamer-mpromonet.cloud.okteto.net/?layout=2x4)

## Using docker image

You can start the application using the docker image:

```sh
docker run -p 8000:8000 -it mpromonet/webrtc-streamer
```

You can expose V4L2 devices from your host using:

```sh
docker run --device=/dev/video0 -p 8000:8000 -it mpromonet/webrtc-streamer
```

The container entry point is the webrtc-streamer application, then you can:

- view all commands
  ```sh
  docker run -p 8000:8000 -it mpromonet/webrtc-streamer --help
  ```
- run the container registering a RTSP url:

  ```sh
  docker run -p 8000:8000 -it mpromonet/webrtc-streamer -n raspicam -u rtsp://pi2.local:8554/unicast
  ```
- run the container giving config.json file:

  ```sh
  docker run -p 8000:8000 -v $PWD/config.json:/app/config.json mpromonet/webrtc-streamer
  ```

## Using embedded STUN/TURN server behind a NAT

It is possible to start an embeded [STUN](https://en.wikipedia.org/wiki/STUN)
and [TURN](https://en.wikipedia.org/wiki/Traversal_Using_Relays_around_NAT)
server and publish its URL:

```sh
./webrtc-streamer -S0.0.0.0:3478 -s$(curl -s ifconfig.me):3478
./webrtc-streamer -s- -T0.0.0.0:3478 -tturn:turn@$(curl -s ifconfig.me):3478
./webrtc-streamer -S0.0.0.0:3478 -s$(curl -s ifconfig.me):3478 -T0.0.0.0:3479 -tturn:turn@$(curl -s ifconfig.me):3479
```

The command `curl -s ifconfig.me` is getting the public IP, it could also given
as a static parameter.

In order to configure the NAT rules using the upnp feature of the router, it is
possible to use
[upnpc](https://manpages.debian.org/unstable/miniupnpc/upnpc.1.en.html) like
this:

```sh
upnpc -r 8000 tcp 3478 tcp 3478 udp
```

Adapting with the HTTP port, STUN port, TURN port.

## HTML Embedding

Instead of using the internal HTTP server, it is easy to display a WebRTC stream
in a HTML page served by another HTTP server. The URL of the WebRTC-streamer to
use should be given creating the
[WebRtcStreamer](http://htmlpreview.github.io/?https://github.com/mpromonet/webrtc-streamer-html/blob/master/jsdoc/WebRtcStreamer.html)
instance:

```js
var webRtcServer = new WebRtcStreamer(<video tag>, <webrtc-streamer url>);
```

A short sample HTML page using webrtc-streamer running locally on port 8000:

```html
<html>
<head>
<script src="libs/adapter.min.js" ></script>
<script src="webrtcstreamer.js" ></script>
<script>        
	var webRtcServer      = null;
	window.onload         = function() { 
		webRtcServer      = new WebRtcStreamer("video",location.protocol+"//"+location.hostname+":8000");
		webRtcServer.connect("rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov");
	}
	window.onbeforeunload = function() { webRtcServer.disconnect(); }
</script>
</head>
<body> 
	<video id="video" />
</body>
</html>
```

## Using WebComponents

WebRTC-streamer provides its own
[Web Components](https://www.webcomponents.org/) as an alternative way to
display a WebRTC stream in an HTML page. For example:

```html
<html>
<head>
	<script type="module" src="webrtc-streamer-element.js"></script>
</head>
<body>
	<webrtc-streamer url="rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov"></webrtc-streamer>
</body>
</html>
```

[Live Demo](https://webrtc-streamer-mpromonet.cloud.okteto.net/map.html)

## Using WHEP

It allow to stream using draft standard [WHEP](https://www.ietf.org/archive/id/draft-murillo-whep-02.txt)

[WebRTC player](https://github.com/Eyevinn/webrtc-player) can display WebRTC stream from webrtc-streamer.

## Connect to Janus Gateway Video Room

A simple way to publish WebRTC stream to a
[Janus Gateway](https://janus.conf.meetecho.com) Video Room is to use the
[JanusVideoRoom](http://htmlpreview.github.io/?https://github.com/mpromonet/webrtc-streamer-html/blob/master/jsdoc/JanusVideoRoom.html)
interface

```js
var janus = new JanusVideoRoom(<janus url>, <webrtc-streamer url>)
```

A short sample to publish WebRTC streams to Janus Video Room could be:

```html
<html>
<head>
<script src="janusvideoroom.js" ></script>
<script>        
	var janus = new JanusVideoRoom("https://janus.conf.meetecho.com/janus", null);
	janus.join(1234, "rtsp://pi2.local:8554/unicast","pi2");
	janus.join(1234, "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov","media");	    
</script>
</head>
</html>
```

[![Screenshot](images/janusvideoroom.png)](https://webrtc-streamer-mpromonet.cloud.okteto.net/janusvideoroom.html)

[Live Demo](https://webrtc-streamer-mpromonet.cloud.okteto.net/janusvideoroom.html)

This way the communication between
[Janus API](https://janus.conf.meetecho.com/docs/JS.html) and
[WebRTC Streamer API](https://webrtc-streamer-mpromonet.cloud.okteto.net/help)
is implemented in Javascript running in browser.

The same logic could be implemented in NodeJS using the same JS API:

```js
global.request = require("then-request");
var JanusVideoRoom = require("./html/janusvideoroom.js");
var janus = new JanusVideoRoom(
  "http://192.168.0.15:8088/janus",
  "http://192.168.0.15:8000",
);
janus.join(1234, "videocap://0", "video");
```

## Connect to Jitsi

A simple way to publish WebRTC stream to a [Jitsi](https://meet.jit.si) Video
Room is to use the
[XMPPVideoRoom](http://htmlpreview.github.io/?https://github.com/mpromonet/webrtc-streamer-html/blob/master/jsdoc/XMPPVideoRoom.html)
interface

```js
var xmpp = new XMPPVideoRoom(<xmpp server url>, <webrtc-streamer url>)
```

A short sample to publish WebRTC streams to a Jitsi Video Room could be:

```html
<html>
<head>
<script src="libs/strophe.min.js" ></script>
<script src="libs/strophe.muc.min.js" ></script>
<script src="libs/strophe.disco.min.js" ></script>
<script src="libs/strophe.jingle.sdp.js"></script>
<script src="libs/jquery-3.5.1.min.js"></script>
<script src="xmppvideoroom.js" ></script>
<script>        
	var xmpp = new XMPPVideoRoom("meet.jit.si", null);
	xmpp.join("testroom", "rtsp://wowzaec2demo.streamlock.net/vod/mp4:BigBuckBunny_115k.mov","Bunny");	    
</script>
</head>
</html>
```

[Live Demo](https://webrtc-streamer-mpromonet.cloud.okteto.net/xmppvideoroom.html)

## Build

### Dependencies

This package depends on the following packages:

- [WebRTC Native Code Package](http://www.webrtc.org) for WebRTC
- [civetweb HTTP server](https://github.com/civetweb/civetweb) for HTTP server
- [live555](http://www.live555.com/liveMedia) for RTSP/MKV source

The following steps are required to build the project, and will install the
dependencies above:

1. Install the Chromium depot tools

   ```sh
   pushd ..
   git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
   export PATH=$PATH:`realpath depot_tools`
   popd
   ```
2. Download WebRTC

   ```sh
   mkdir ../webrtc
   pushd ../webrtc
   fetch --no-history webrtc 
   popd
   ```

3. Build WebRTC Streamer

   ```sh
   cmake . && make
   ```

It is possible to specify cmake parameters `WEBRTCROOT` &
`WEBRTCDESKTOPCAPTURE`:

- `$WEBRTCROOT/src` should contains source (default is $(pwd)/../webrtc)
- `WEBRTCDESKTOPCAPTURE` enabling desktop capture if available (default is ON)
