B4J Code Snippet If you're looking to hide the Command Prompt (CMD) window when running a script or program

If you're looking to hide the Command Prompt (CMD) window when running a script or program,
there are several approaches depending on your needs.

I wanted to hide the Command Prompt (CMD) window and the FFmpeg.exe program window at the same time.
Here is my solution that was implemented in Windows 11 version, using a script (Script_converting.cmd) & (Script_converting.vbs):

Dim media  As String = "0000.media" 'input file
Dim mp4    As String = "0000.mp4"     'output file
Dim script As String = File.Combine(File.DirApp, "\e-Scripts\Script_converting.vbs")

If Not(File.Exists(File.DirApp, "\e-Scripts\Script_converting.cmd")) Or Not(File.Exists(File.DirApp, "\e-Scripts\Script_converting.vbs")) Then
    If Not(File.Exists(File.DirApp, "e-Scripts")) Then File.MakeDir(File.DirApp, "e-Scripts")
    If Not(File.Exists(File.DirApp, "\e-Scripts\Script_converting.cmd")) Then
        Wait For (File.CopyAsync(File.DirAssets, "Script_converting.cmd", File.DirApp, "\e-Scripts\Script_converting.cmd")) Complete (Success As Boolean)
    End If
    If Not(File.Exists(File.DirApp, "\e-Scripts\Script_converting.vbs")) Then
        Wait For (File.CopyAsync(File.DirAssets, "Script_converting.vbs", File.DirApp, "\e-Scripts\Script_converting.vbs")) Complete (Success As Boolean)
    End If
End If

start_cmd(script & " " & File.Combine(File.DirApp, "\e-Scripts") & " 3 " & media & " " & mp4) 'Windows command script (with command interpreter 'cmd.exe')

Private Sub start_cmd(fScript As String)
    shl.Initialize("shl", "cmd.exe", Array As String("/c", fScript)) '(use a vbscript called ".vbs" only to run the batch file with hidden dos screen)
    shl.WorkingDirectory = "D:\TMP\SessionData" 'Target file conversion directory
    shl.RunSynchronous(-1)
End Sub

Private Sub shl_ProcessCompleted (Success As Boolean, ExitCode As Int, StdOut As String, StdErr As String)
    If Success = True And ExitCode = 0 Then
        #If Debug
        Log("SHL Process, Success") 'The Windows command script has completed.
        #End If
    End If
End Sub

Overview of details:
In the file attached here (Script_converting.cmd):
1. I used the flag /B
2. I used the parameter /affinity 3 - this means that it will use CPU0 i CPU1
3. I used six (threads fffmpeg): -threads 6
4. I used the parameter -nostats -nostdin - I missed creating statistics

In the file attached here (Script_converting.vbs):
1. WScript.Arguments(0) - The parameter used determines the directory for the file Script_converting.cmd
2. WScript.Arguments(1) - The parameter used determines the jump to the label IF "%1"=="3" GOTO cnverting_med (see: Script_converting.cmd)
3. WScript.Arguments(2) - The parameter used determines the directory for the file 0000.media
4. WScript.Arguments(3) - The parameter used determines the directory for the file 0000.mp4
5. I used the parameter to hide the FFmpeg.exe, window as well "0, False"

> See file: Script_converting.cmd

:cnverting_med
C:\Windows\System32\cmd.exe /c start /low /B /affinity 3 D:\ffmpeg\bin\ffmpeg.exe -i %2 -s 960x540 -c:v libx264 -b:v 1260k -r 24 -x264opts keyint=48:min-keyint=48:no-scenecut -profile:v main -preset medium -movflags +faststart -nostats -nostdin -threads 6 %3

> See file: Script_converting.vbs

CreateObject("Wscript.Shell").Run WScript.Arguments(0) & "\Script_converting.cmd " & WScript.Arguments(1) & " " & WScript.Arguments(2) & " " & WScript.Arguments(3), 0, False

RecDesk is Using ffmpeg... I am sure will be useful with your knowledge at ffmpeg...

by the way: I am searching somehow using video chunks of ffmpeg... or pipepline.. in other words I want to split it and send via web or mqtt and stream it... do you know any way ?
