The aim of this project is develop a WebRTC screenshare designed for streaming video games and
accepting remote inputs.
There will be ansible instructions which can be executed inside into any virtual environment. This will
be a plugin which complements the project P2PRC

Testing with X-Plane 11
Laplace
Based on the fork: https://github.com/Akilan1999/laplace/tree/keyboard_mouse
Installation
Installation required to share keyboard and mouse
Currently, you can either use x2x or Barrier KVM
We need to ensure that the client has SSH client installed or Barrierc.
What is x2x?
x2x allows the keyboard, mouse on one X display to be used to control another X display. It also shares X clipboards between the displays.
Note: x2x runs on top of SSH.
What is Barrier KVM?
Barrier is software that mimics the functionality of a KVM switch, which historically would allow you to use a single keyboard and mouse to control multiple computers by physically turning a dial on the box to switch the machine you're controlling at any given moment. Barrier does this in software, allowing you to tell it which machine to control by moving your mouse to the edge of the screen, or by using a keypress to switch focus to a different system.

Program Execution
Executing this project basically serves an HTTP server that will host the frontend and the WebSocket implementation.
Note that you sometimes need to run HTTPs in order for browser to connect to websocket.
$ ./laplace --help
-BinaryToExecute string
Providing path (i.e Absolute path) of binary to execute
-addr string
Listen address (default "0.0.0.0:443")
-certFile string
TLS cert file (default "files/server.crt")
-headless
Creating screenshare using headless mode
-keyFile string
TLS key file (default "files/server.key")
-killChromium
Kills all chromuim
-killServer
Kills the laplace
-roomInfo
Getting room id of headless server
-setconfig
Generates a config file
-tls
Use TLS
By default, you can run the executable without any argument to listen to TLS port 443.
A self-signed certificate files are provided to ease up development. If you want to run
with barrier KVM. Run as non-root.
Starting game when screen-share is triggered
This requires creating a bash script to trigger when the screenshare begins.
Ex: Start X-Plane 11
Let's call this script xplane11.sh
# Navigating to the directory where X-Plane11 is present
cd /path/.local/share/Steam/steamapps/common/X-Plane\ 11/
# Execute X-Plane 11 binary
./X-Plane-x86_64
Open config file
{
"barrierhostname": "<barrier host name>",
"ipaddress": "0.0.0.0",
"rooms": "<path to room.json file>",
"scripttoexecute": "<path to script to execute (In case the Xplane 11 script)>",
"sshpassword": "<SSH password for x2x>",
"systemusername": "<system username>"
}
Call from built script which starts the server , creates room and outputs the ID
sh run.sh <IPV6 or Public IPV4 address of server>
Note: This script starts the server using the port 8888 by default
The 2 steps below are if you want to start them command by command
Starting server
$ ./laplace -tls -addr 0.0.0.0:8888
2020/03/25 01:01:10 Listening on TLS: 0.0.0.0:8888
Starting screenshare
./laplace -headless -addr <public ip address of server>
You can then open https://localhost:8888/ to view Laplace page.
You may need to add certificate exceptions. In Chrome, you can type thisisunsafe.
