• Force a vbscript to open command prompt in 64bit instead of 32bit

  26 juin 2015, par Arvo Bowen

  I have been trying to get this script to work all day !

  Here are some facts about my situation...

  • I have a program named "ffmpeg.exe" in my "C :\Windows\System32\" folder.
  • I DO NOT have that program in my "C :\Windows\SysWOW64\" folder.

  Currently this is the script I have...

  Option Explicit
  
  
  
  Dim oFSO, oShell, sCommand
  
  Dim sFilePath, sTempFilePath
  
  
  
  Set oFSO = CreateObject("Scripting.FileSystemObject")
  
  
  
  sFilePath = "C:\test\in_video.mkv"
  
  sTempFilePath = "C:\test\out_video.mp4"
  
  
  
  sCommand = "%comspec% /k ffmpeg -n -i """ + sFilePath + """ -c:v copy -c:a copy """ + sTempFilePath + """"
  
  WScript.Echo sCommand
  
  Set oShell = WScript.CreateObject("WScript.Shell")
  
  oShell.Run sCommand, 1, True
  
  Set oShell = Nothing
  
  
  
  Set oFSO = Nothing

  If I run this script manually at a command prompt then it seems to work just fine. But if I let another app run it (for example in this case uTorrent), it runs the script as expected but when it tries to process the oShell.Run command it runs that in a 32bit environment ! Then I get this...
  

  If I try to open up a new command prompt (nothing special) i seems to default to a 64bit environment and then I can type "ffmpeg" and it shows me the help content as expected.

  So for some reason I can’t get the script to run applications (specifically CMD) in the 64bit environment. Anyone know how I can achieve this ?

  ---

  Update

  Seems that my script is in fact being ran in 32bit mode ! Even though the script title bar says "C :\Windows\System32\cscript.exe", which is a 64bit environment !!

  I used the following script to determine that it was running in a 32bit environment...

  Dim WshShell
  
  Dim WshProcEnv
  
  Dim system_architecture
  
  Dim process_architecture
  
  
  
  Set WshShell =  CreateObject("WScript.Shell")
  
  Set WshProcEnv = WshShell.Environment("Process")
  
  
  
  process_architecture= WshProcEnv("PROCESSOR_ARCHITECTURE") 
  
  
  
  If process_architecture = "x86" Then    
  
      system_architecture= WshProcEnv("PROCESSOR_ARCHITEW6432")
  
  
  
      If system_architecture = ""  Then    
  
          system_architecture = "x86"
  
      End if    
  
  Else    
  
      system_architecture = process_architecture    
  
  End If
  
  
  
  WScript.Echo "Running as a " & process_architecture & " process on a " _ 
  
      & system_architecture & " system."

• file : Move win32 utf8->wchar open wrapper to libavutil

  8 août 2013, par Martin Storsjö

  file : Move win32 utf8->wchar open wrapper to libavutil
  When libavformat was changed to use the new avpriv_open function
  
  in 51eb213d001, this silently bypassed the existing wrapper for
  
  win32. Move the win32 wrapper into libavutil/file.c to make sure
  
  it gets called everywhere (not just in the libavformat case).
  This makes sure that non-ascii file names gets opened properly
  
  (where file names internally are stored as utf8, but they get
  
  converted to wchar_t and opened with _wsopen).
