# nginx rtmp multistream
2+
3+
## TL;DR
4+
Edit conf/nginx.conf
5+
Then run the following commands:
6+
```sh
7+
docker-compose build
8+
docker-compose up -d
9+
```
10+
RTMP server now available push to rtmp://server-hostname/live
11+
12+
## About
13+
This Docker image is for having a central point to stream to multiple streaming providers at once.
14+
Providers included in this config are: Twitch, Youtube, Facebook
15+
Instagram is not properly supported due to multiple reasons, one is they don't official support this..
16+
17+
This Dockerfile will let you run nginx with the compiled rtmp module from https://github.com/sergey-dryabzhinsky/nginx-rtmp-module
18+
19+
This rtmp module doesn't properly support pushing to rtmps however, so we so a little magic:
20+
with docker-compose we also spin up a [stunnel](https://www.stunnel.org/)
21+
this stunnel makes it possible to translate traffic to rtmps for the module.
22+
23+
## Prerequisites
24+
You will need to have both [docker](https://www.docker.com/) and [docker-compose](https://docs.docker.com/compose/install/) installed on your machine.
25+
Have at least 4 cores so transcoding doesn't take your entire machine, so a Raspberry pi is __not__ recommended.
26+
27+
## Config
28+
You will need to edit the nginx.conf file in the conf directory.
29+
30+
update the following things:
31+
* ALLOWED_BROADCAST_IP : The IP address from where the stream will be pushed to this instance.
32+
* TWITCH_KEY : The twitch stream key
33+
* FACEBOOK_KEY : The Facebook stream key
34+
* INSTAGRAM_KEY : The instagram stream key (optional, this is disabled by default for now in the 'live' app)
35+
* YOUTUBE_KEY : The yourube stream key
36+
37+
You can disable any of these by commenting out either their 'push' or 'exec' in the live application.
38+
39+
## Usage
40+
First we build the docker image
41+
```sh
42+
docker-compose build
43+
```
44+
Then make sure you have updated the conf/nginx.conf
45+
```sh
46+
docker-compose up -d
47+
```
48+
49+
## Notes
50+
Check to make sure the streaming push links are still up to date with what the platform gives you..
51+
it usually doesn't change, but do verify
52+
for facebook/instagram also check the conf/stunnel.conf
53+
54+
If you want to experiment with instagram, be free to figure out the right encoder settings and a way to get the rtmp key
55+
if you find a clean solution and want to share back, I'll accept it.
