+# mpvSockets
+create one sockets per mpv instance (with the instance's process **ID** (PID), (**unique**)), instead of one socket for the last started instance
+
+dangling sockets for crashed or killed instances is an issue, 
+not sure if this script should handle/remove them or the clients/users, or both.
+
+# Installation
+Download the single script file to your mpv-scripts-directory
+## Linux / unixes:
+``` bash
+curl "https://raw.githubusercontent.com/wis/mpvSockets/master/mpvSockets.lua" --create-dirs -o "$Your_Mpv_Scripts_Directory_Location/mpvSockets.lua"
+```
+if you're on Linux, most likely the location is `~/.config/mpv/scripts`, so run this before:
+``` bash
+$Your_Mpv_Scripts_Directory_Location=$HOME/config/mpv/scripts
+```
+## Windows (untested)
+powershell:
+``` powershell
+Invoke-WebRequest -OutFile "$env:LOCALAPPDATA\mpv\scripts\mpvSockets.lua" "https://raw.githubusercontent.com/wis/mpvSockets/master/mpvSockets.lua"
+```
+
+# Usage, with Mpv's [JSON IPC](https://github.com/mpv-player/mpv/blob/master/DOCS/man/ipc.rst)
+## Linux / unixes (unix sockets):
+a script that pauses all running mpv instances:
+bash:
+``` bash
+#!/bin/bash
+for i in $(ls /tmp/mpvSockets/*); do
+	echo '{ "command": ["set_property", "pause", true] }' | socat - "$i";
+done
+# Socat  is  a  command  line based utility that establishes two bidirec-tional byte streams  and	 transfers  data  between  them.
+# available on Linux and FreeBSD, propably most unixes. you can also use 
+```
+
+## Windows (named pipes):
+quote from https://mpv.io/manual/stable/#command-prompt-example
+> Unfortunately, it's not as easy to test the IPC protocol on Windows, since Windows ports of socat (in Cygwin and MSYS2) don't understand named pipes. In the absence of a simple tool to send and receive from bidirectional pipes, the echo command can be used to send commands, but not receive replies from the command prompt.
+>
+> Assuming mpv was started with:
+>
+> `mpv file.mkv --input-ipc-server=\\.\pipe\mpvsocket`
+> You can send commands from a command prompt:
+>
+> `echo show-text ${playback-time} >\\.\pipe\mpvsocket`
+To be able to simultaneously read and write from the IPC pipe, like on Linux, it's necessary to write an external program that uses overlapped file I/O (or some wrapper like .NET's NamedPipeClientStream.)
+
+powershell client writer and reader (untested):
+``` powershell
+# socat.ps1
+# usage: socat.ps1 <Pipe-name> <Message>
+$sockedName = args[0]
+$message = args[1]
+
+$npipeClient = new-object System.IO.Pipes.NamedPipeClientStream('.', $socketName, [System.IO.Pipes.PipeDirection]::InOut, [System.IO.Pipes.PipeOptions]::None, [System.Security.Principal.TokenImpersonationLevel]::Impersonation)
+
+$pipeReader = $pipeWriter = $null
+try {
+    $npipeClient.Connect()
+    $pipeReader = new-object System.IO.StreamReader($npipeClient)
+    $pipeWriter = new-object System.IO.StreamWriter($npipeClient)
+    $pipeWriter.AutoFlush = $true
+
+    $pipeWriter.WriteLine($message)
+
+    while (($data = $pipeReader.ReadLine()) -ne $null) {
+      $data
+    }
+}
+catch {
+    "An error occurred that could not be resolved."
+}
+finally {
+    $npipeClient.Dispose()
+}
+```
