Drag-and-drop a file to script to run ffmpeg passing the file as parameter Topic is solved

[Ross]

Hi, it's been a long while since I last had drag-and-drop work with AutoHotKey; I believe it has something to do with that option upon installation (enable drag-and-drop) which is now disabled by default. So I don't even know whether it's still possible; I install AutoHotKey via Chocolatey.

So say I have a mp3 file on my desktop, or any other audio file, and want to run the following:

Code: Select all

Run ffmpeg -i "in.mp3" -filter:a "atempo=1.7" -vn "C:\Users\Leo\Desktop\out.mp3" -y

...where the "in.mp3" is the dragged file onto the ahk script's icon. How to make it work so that the dragged file's path will take the "in.mp3" parameter in the line above?

Thanks guys, I was able to use one example in the aforementioned topic and adapted my script to:

Code: Select all

Loop, %0%  ; For each parameter:
{
	param := %A_Index%  ; Fetch the contents of the variable whose name is contained in A_Index.
	Run ffmpeg -i %param% -filter:a "atempo=1.7" -vn "C:\Users\me\Desktop\out.mp3" -y
	; MsgBox, 4,, Parameter number %A_Index% is %param%.  Continue?
}

The GUI approach pointed by Garry was also useful:

Hello.
Do not tell me, the code on a non-compiled AHK file works, but as soon as I compile it into an exe

Code: Select all

Loop, %0%

Stops working, how to fix it?

Here is what part of my code looks like:

Code: Select all

Loop, %0%
{
	if FileExist("TI.exe"){
	RunWait, TI.exe cmd.exe ;starts services
	sleep 1000
	param := %A_Index%
	RunWait, powershell.exe -Command "Get-ChildItem %param% | ForEach-Object {Add-AppxPackage -Path $_.FullName}"
}
else{
	UrlDownloadToFile, ;downloads the file if TI. exe is not nearby and the command will be executed again
	RunWait, %A_Temp%\TI.exe ;starts the service
	sleep 1000
	param := %A_Index%
	RunWait, powershell.exe -Command "Get-ChildItem %param% | ForEach-Object {Add-AppxPackage -Path $_.FullName}"
}
}

I throw in a compiled exe file to install appx and bundle files, but they stop installing as soon as AHK turns into EXE
How to fix the code?

If the loop is not executing, then you can use the script to display the value of its parameter.

If you pass no command-line parameters to your compiled script, then the number of parameters is zero.

Code: Select all

#Requires AutoHotkey v1.1.33
MsgBox Number=%0%
Loop %0%
 MsgBox 123
