# nginx-rtmp
|
|
||||||
|
|
||||||
[**Docker**](https://www.docker.com/) image with [**Nginx**](http://nginx.org/en/) using the [**nginx-rtmp-module**](https://github.com/arut/nginx-rtmp-module) module for live multimedia (video) streaming.
|
|
||||||
|
|
||||||
## Description
|
|
||||||
|
|
||||||
This [**Docker**](https://www.docker.com/) image can be used to create an RTMP server for multimedia / video streaming using [**Nginx**](http://nginx.org/en/) and [**nginx-rtmp-module**](https://github.com/arut/nginx-rtmp-module), built from the current latest sources (Nginx 1.15.0 and nginx-rtmp-module 1.2.1).
|
|
||||||
|
|
||||||
This was inspired by other similar previous images from [dvdgiessen](https://hub.docker.com/r/dvdgiessen/nginx-rtmp-docker/), [jasonrivers](https://hub.docker.com/r/jasonrivers/nginx-rtmp/), [aevumdecessus](https://hub.docker.com/r/aevumdecessus/docker-nginx-rtmp/) and by an [OBS Studio post](https://obsproject.com/forum/resources/how-to-set-up-your-own-private-rtmp-server-using-nginx.50/).
|
|
||||||
|
|
||||||
The main purpose (and test case) to build it was to allow streaming from [**OBS Studio**](https://obsproject.com/) to different clients at the same time.

## Details
|
|
||||||
|
|
||||||
## How to use
|
|
||||||
|
|
||||||
* For the simplest case, just run a container with this image:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
docker run -d -p 1935:1935 --name nginx-rtmp tiangolo/nginx-rtmp
|
|
||||||
```
|
|
||||||
|
|
||||||
## How to test with OBS Studio and VLC
|
|
||||||
|
|
||||||
* Run a container with the command above
|
|
||||||
|
|
||||||
|
|
||||||
* Open [OBS Studio](https://obsproject.com/)
|
|
||||||
* Click the "Settings" button
|
|
||||||
* Go to the "Stream" section
|
|
||||||
* In "Stream Type" select "Custom Streaming Server"
|
|
||||||
* In the "URL" enter the `rtmp://<ip_of_host>/live` replacing `<ip_of_host>` with the IP of the host in which the container is running. For example: `rtmp://192.168.0.30/live`
|
|
||||||
* In the "Stream key" use a "key" that will be used later in the client URL to display that specific stream. For example: `test`
|
|
||||||
* Click the "OK" button
|
|
||||||
* In the section "Sources" click de "Add" button (`+`) and select a source (for example "Screen Capture") and configure it as you need
|
|
||||||
* Click the "Start Streaming" button
|
|
||||||
|
|
||||||
|
|
||||||
* Open a [VLC](http://www.videolan.org/vlc/index.html) player (it also works in Raspberry Pi using `omxplayer`)
|
|
||||||
* Click in the "Media" menu
|
|
||||||
* Click in "Open Network Stream"
|
|
||||||
* Enter the URL from above as `rtmp://<ip_of_host>/live/<key>` replacing `<ip_of_host>` with the IP of the host in which the container is running and `<key>` with the key you created in OBS Studio. For example: `rtmp://192.168.0.30/live/test`
|
|
||||||
* Click "Play"
|
|
||||||
* Now VLC should start playing whatever you are transmitting from OBS Studio
|
|
||||||
|
|
||||||
## Debugging
|
|
||||||
|
|
||||||
If something is not working you can check the logs of the container with:
|
|
||||||
|
|
||||||
```bash
|
|
||||||
docker logs nginx-rtmp
|
|
||||||
```
|
|
||||||
|
|
||||||
## Extending
|
|
||||||
|
|
||||||
If you need to modify the configurations you can create a file `nginx.conf` and replace the one in this image using a `Dockerfile` that is based on the image, for example:
|
|
||||||
|
|
||||||
```Dockerfile
|
|
||||||
FROM tiangolo/nginx-rtmp
|
|
||||||
|
|
||||||
COPY nginx.conf /etc/nginx/nginx.conf
|
|
||||||
```
|
|
||||||
|
|
||||||
The current `nginx.conf` contains:
|
|
||||||
|
|
||||||
```Nginx
|
|
||||||
worker_processes auto;
|
|
||||||
rtmp_auto_push on;
|
|
||||||
events {}
|
|
||||||
rtmp {
|
|
||||||
server {
|
|
||||||
listen 1935;
|
|
||||||
listen [::]:1935 ipv6only=on;
|
|
||||||
|
|
||||||
application live {
|
|
||||||
live on;
|
|
||||||
record off;
|
|
||||||
}
|
|
||||||
}
|
|
||||||
}
|
|
||||||
```
|
|
||||||
|
|
||||||
You can start from it and modify it as you need. Here's the [documentation related to `nginx-rtmp-module`](https://github.com/arut/nginx-rtmp-module/wiki/Directives).

|
||||||
|
|
||||||
## Technical details
|
|
||||||
|
|
||||||
* This image is built from the same base official images that most of the other official images, as Python, Node, Postgres, Nginx itself, etc. Specifically, [buildpack-deps](https://hub.docker.com/_/buildpack-deps/) which is in turn based on [debian](https://hub.docker.com/_/debian/). So, if you have any other image locally you probably have the base image layers already downloaded.
|
|
||||||
|
|
||||||
* It is built from the official sources of **Nginx** and **nginx-rtmp-module** without adding anything else. (Surprisingly, most of the available images that include **nginx-rtmp-module** are made from different sources, old versions or add several other components).
|
|
||||||
|
|
||||||
* It has a simple default configuration that should allow you to send one or more streams to it and have several clients receiving multiple copies of those streams simultaneously. (It includes `rtmp_auto_push` and an automatic number of worker processes).
