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

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

nice !

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 ?

I want to understand well, do you want to divide, for example, one video file into selected fragments using FFMPEG? If so, I think I still have such a source of code, but I have to look well, it will take a while.

..
I want to record from a source... and the same time... send some "ms" / chuncks / frames (i don't know what exactly) to other ip (may be using mqtt) and from the other side playing those somehow... until the source stop sending

Stream with my way..

(ps: the communication way is not a problem... the problem is how to get chunks ... and how to play them)
