# unicorn_screams
|
||
|
|
|
||
|
|
It is what it says on the tin. Make [scream](https://github.com/duncanthrax/scream) work
|
||
|
|
|
||
|
|
## THE CONTEXT
|
||
|
|
|
||
|
|
I have a windows machine (cursed), it is inside a NAT with my main personal
|
||
|
|
machine outside of it due to reasons (double cursed).
|
||
|
|
I want to have transparent control from my
|
||
|
|
linux personal machine into that windows machine (triple cursed).
|
||
|
|
|
||
|
|
I have configured [Tailscale](https://tailscale.com) between them so they have
|
||
|
|
a nice NAT-punched connection to talk through.
|
||
|
|
|
||
|
|
The transparent control part of it is successfully handled by
|
||
|
|
[barrier](https://github.com/debauchee/barrier/).
|
||
|
|
|
||
|
|
However, *audio streaming is not a feature of Barrier*.
|
||
|
|
|
||
|
|
I have attempted to use ffmpeg to capture audio via DirectShow from a VBCable
|
||
|
|
(because somehow my audio driver doesn't give me the Stereo Mix device), sending
|
||
|
|
it as RTP over tailscale, and it *works*, *kind of*.
|
||
|
|
|
||
|
|
The latency is **TERRIBLE** after a while, I don't fully know why. A certain
|
||
|
|
sentient machine suggested scream to me. It is an interesting, simple tool.
|
||
|
|
|
||
|
|
Problem is: *Tailscale does not support UDP Multicast*. How the fuck do I
|
||
|
|
connect the machines then????
|
||
|
|
|
||
|
|
This is where this program steps in.
|
||
|
|
|
||
|
|
It will take the inputs from scream's UDP address (you have to configure it
|
||
|
|
as unicast instead of multicast), and it'll simply relay them to another UDP
|
||
|
|
address (in my case, my Tailscale address)
|
||
|
|
|
||
|
|
Why not set the Tailscale address on scream's unicast settings?
|
||
|
|
|
||
|
|
It didn't work.
|
||
|
|
|
||
|
|
Fuck if I know why!!!
|
||
|
|
|
||
|
|
## Pre-setup
|
||
|
|
|
||
|
|
- Install the scream driver
|
||
|
|
- Configure unicast: https://github.com/duncanthrax/scream#using-unicast-instead-of-multicast-optional
|
||
|
|
- In my setup, address is `127.0.0.1` and port is `6970`
|
||
|
|
|
||
|
|
## Setup
|
||
|
|
|
||
|
|
### Build
|
||
|
|
|
||
|
|
This can be done on a linux machine.
|
||
|
|
|
||
|
|
- Install [zig master branch](https://ziglang.org/download/).
|
||
|
|
- `zig build -Dtarget=x86_64-windows-gnu`
|
||
|
|
- If you're me: `sudo tailscale file cp ./zig-out/bin/unicorn_screams.exe your-machine:`
|
||
|
|
|
||
|
|
### Run
|
||
|
|
|
||
|
|
- Syntax: `.\unicorn_screams.exe from_address from_port to_address to_port`
|
||
|
|
- In my setup: `.\unicorn_screams.exe 127.0.0.1 6970 100.123.69.69 6970`
|
||
|
|
- Load your scream receiver of choice
|
||
|
|
- In my setup, with the default unix receiver, `./scream -u -i 100.123.69.69 -p 6970`
