mpv not opening file in same process

[nmoorthy524]

I am on the latest windows 64 bit build available here: https://mpv.srsfckn.biz/ (10/20 as of today). I already have mpv as the default filetype. When I have mpv already open and I click on a video to play in my file explorer, instead of playing in the already open mpv process, it creates a new one so now there's 2 mpvs playing. Is this as intended and if so, how do I make it stick to using only 1 process?

It's a feature. On Linux there's a script (umpv) to get one-process behavior, but not on Windows. (Though you could attempt to write such a script for Windows.)

I need this feature，It could open many file at the same time？
how could I switch on this function？

As a possible workaround, there's rossy's mpv-open-file-dialog Lua script.

I found 2 things, but I'm not sure how to use them. Notify me if you know.
This uses a program and registry entry.
zenden2k/context-menu-launcher
and the other is
Powershell Code

$process = "mspaint"
$ret = Get-Process -Name $process -ErrorAction SilentlyContinue 
if ($ret) {
	Write-Host "INFO: $process already running, skipping start of another instance of the same process"
} else {
	Write-Host "VERBOSE: Starting $process now"
	Invoke-Item "$process.exe"	
}

Another script
It runs properly from powershell.

if (-Not (Get-Process "mpv" -ErrorAction SilentlyContinue | Where-Object {-not $_.HasExited }))
{
  & "C:\mpv\mpv.exe"
}

With all due respect, using PowerShell to do just that is stupid damn, it's like wanting to kill flies to cannon shots. Not to mention that PowerShell is just another "permanent security hole" in the operating system.

This batch do exact the same:

@echo off
tasklist | find /i "mpv.exe"
if errorlevel 1 start "" mpv.exe %*

A more hostile variant:

@echo off
taskkill /im "mpv.exe" /f
start "" mpv.exe %*

Less hostile...:

@echo off
taskkill /im "mpv.exe"
ping 127.0.0.1 -n 2 >nul
start "" mpv.exe %*

cya

ping 127.0.0.1 -n 2 >nul

Just to avoid any possible confusion: This is just the old wait trick..
