# Live Streaming Server Setup
|
||||||
|
|
||||||
|
I have set up my own [RTMP][rtmp] server that allows me to live stream to [my own
|
||||||
|
infrastructure][streampage]. This allows me to own my own setup and not need to
|
||||||
|
rely on other services such as Twitch or YouTube. As a side effect of doing
|
||||||
|
this, I can enable people who use my streaming server to use picture-in-picture
|
||||||
|
mode in iPadOS without having to hack the streaming app, among other things.
|
||||||
|
|
||||||
|
This is part of my 2020 goal to reduce my dependencies on corporate social
|
||||||
|
platforms as much as possible.

|
||||||
|
[streampage]: https://home.cetacean.club/stream
|
||||||
|
|
||||||
|
I chose to do my setup with a few key parts:
|
||||||
|
|
||||||
|
- [docker-nginx-rtmp][docker-rtmp]
|
||||||
|
- [hls.js][hlsjs]
|
||||||
|
- [stream.html][streamhtml]
|
||||||
|
- [Caddy][caddy]
|
||||||
|
|
||||||
|

|
||||||
|
[hlsjs]: https://hls-js.netlify.com/demo/
|
||||||
|
[streamhtml]: https://gist.github.com/Xe/fadf1100a8152a3f328fc07522cf8176

||||||

|
||||||
|
|
||||||
|
## RTMP Server
|
||||||
|
|
||||||
|
I chose to use [docker-nginx-rtmp][docker-rtmp] as a pre-packaged solution for
|
||||||
|
my RTMP server. This means I could set it up to ingest via my [WireGuard
|
||||||
|
VPN][sts-wireguard] with very little work. Here is the docker command I run on
|
||||||
|
my VPN host:
|
||||||
|
|
||||||
|
[sts-wireguard]: https://christine.website/blog/series/site-to-site-wireguard
|
||||||
|
|
||||||
|
```console
|
||||||
|
$ docker run \
|
||||||
|
--restart always \
|
||||||
|
-dit \
|
||||||
|
-p 10.77.0.1:1935:1935 \
|
||||||
|
-p 127.0.0.1:8080:80 \
|
||||||
|
--name rtmp-server \
|
||||||
|
alfg/nginx-rtmp
|
||||||
|
```
|
||||||
|
|
||||||
|
This starts my RTMP server in a container named `rtmp-server` and automatically
|
||||||
|
restarts it when it goes down. The IP address in the first `--port` (`-p`) flag
|
||||||
|
is the VPN IP address of my main VPN server. This makes me have to be behind my
|
||||||
|
VPN in order to stream to my server, given the total lack of authentication
|
||||||
|
that's involved in RTMP.
|
||||||
|
|
||||||
|
## stream.html
|
||||||
|
|
||||||
|
I have a custom stream page set up [on my server][streampage] that has a
|
||||||
|
friendly little wrapper to the video player. [Here][streamhtml] is the source
|
||||||
|
code for it. It's very short and easy to follow. I have these files at
|
||||||
|
`/srv/http/home.cetacean.club` on my VPN server.
|
||||||
|
|
||||||
|
This wraps [hls.js][hlsjs] so that users on every browser I care to support can
|
||||||
|
watch the stream as it happens.
|
||||||
|
|
||||||
|
## Caddy
|
||||||
|
|
||||||
|
In order to expose the stream data to the world, I use [Caddy][caddy] as a
|
||||||
|
reverse proxy. Here is the configuration that I use for Caddy:
|
||||||
|
|
||||||
|
```
|
||||||
|
home.cetacean.club {
|
||||||
|
# Set up automagic Let's Encrypt
|
||||||
|
tls me@christine.website
|
||||||
|
|
||||||
|
# Proxy the playlist, stream data
|
||||||
|
# and statistics to the rtmp server
|
||||||
|
proxy /hls http://127.0.0.1:8080
|
||||||
|
proxy /live http://127.0.0.1:8080
|
||||||
|
proxy /stat http://127.0.0.1:8080
|
||||||
|
|
||||||
|
# make /stream.html show up as /stream
|
||||||
|
ext .html
|
||||||
|
|
||||||
|
# serve data out of /srv/http/home.cetacan.club
|
||||||
|
# you can put your HTTP document root
|
||||||
|
# anywhere you want, but I like it being
|
||||||
|
# here.
|
||||||
|
root /srv/http/home.cetacean.club
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|

||||||

## Caveats
|
||||||
|
|
||||||
|
Live streaming like this uses _ABSURD_ amounts of bandwidth. Do not set this up
|
||||||
|
on a server that has limited bandwidth. If you need a server that has unlimited
|
||||||
|
bandwidth, check out [SoYouStart][sys]. It's what I use.
|
||||||
|
|
||||||
|
[sys]: https://www.soyoustart.com/ca/en/
|
||||||
|
|
||||||
|
There isn't a good story for recording or announcing streams to this server
|
||||||
|
automatically. I don't consider this a problem, as links can always be sent out
|
||||||
|
manually on social media platforms.
|
||||||
|
|
||||||
|
I hope this little overview of my setup was informative. I'll be
|
||||||
|
streaming [there][streampage] very irregularly, mostly as time permits/the
|
||||||
|
spirit moves me. I plan to stream art, gaming and code.
