## Usage

### Server
* Pull docker image and run:
```
docker pull alfg/nginx-rtmp
docker run -it -p 1935:1935 -p 8080:80 --rm alfg/nginx-rtmp
```
or 

* Build and run container from source:
```
docker build -t nginx-rtmp .
docker run -it -p 1935:1935 -p 8080:80 --rm nginx-rtmp
```

* Stream live content to:
```
rtmp://<server ip>:1935/stream/$STREAM_NAME
```

### SSL 
To enable SSL, see [nginx.conf](nginx.conf) and uncomment the lines:
```
listen 443 ssl;
ssl_certificate     /opt/certs/example.com.crt;
ssl_certificate_key /opt/certs/example.com.key;
```

This will enable HTTPS using a self-signed certificate supplied in [/certs](/certs). If you wish to use HTTPS, it is **highly recommended** to obtain your own certificates and update the `ssl_certificate` and `ssl_certificate_key` paths.

I recommend using [Certbot](https://certbot.eff.org/docs/install.html) from [Let's Encrypt](https://letsencrypt.org).

### OBS Configuration
* Stream Type: `Custom Streaming Server`
* URL: `rtmp://localhost:1935/stream`
* Stream Key: `hello`

### Watch Stream
* In Safari, VLC or any HLS player, open:
```
http://<server ip>:8080/live/$STREAM_NAME.m3u8
```
* Example Playlist: `http://localhost:8080/live/hello.m3u8`
* [VideoJS Player](https://video-dev.github.io/hls.js/stable/demo/?src=http%3A%2F%2Flocalhost%3A8080%2Flive%2Fhello.m3u8)
* FFplay: `ffplay -fflags nobuffer rtmp://localhost:1935/stream/hello`
