• Passing arguments to Powershells Call Operatore - I can't get it to work

  2 janvier 2020, par morgola22

  For some reason I cannot get even the most simple Ffmpeg case to work :

  $pathToFfmpeg = "PathToFfmpeg\ffmpeg.exe"
  
  $video = "PathToVideoFile\video.mp4"
  
  $param = "--i $video", "output.avi"
  
  $execute = &$pathToFfmpeg $param

  This should result in the most basic Ffmpeg usage according to Ffmpeg website : ffmpeg -i input.mp4 output.avi.
  However all I receive is :

  ffmpeg.exe : ffmpeg version git-2020-01-01-7b58702 Copyright (c) 2000-2020 the FFmpeg developers

  So it seems I am doing something wrong. Anybody knows how I get this to work ? I have tried different methods to create the params array and checked with EchoArgs.exe, but no avail. I am out of ideas. It looks like Ffmpeg does not recognise what Powershell is passing to it.

• %a and %%a suddenly don't work in Win 10 cmd and batch file respectively ?

  14 janvier 2017, par cobaltB12

  I was trying to batch convert a folder of .flac to .mp3 using FFMPEG, but when i ran my batch file I got the "%F is unexpected at this time" error, even though i used "%%F" in the batch file. To test what was really the problem, i proceeded to type variations of %F into cmd directly, but could not get it to work either. Did something change in windows 10 regarding the use of variable names in the for loop ?

  cmd commands I tried :

  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%F" in     (*.flac) echo %F
  
  "%F" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for %F in     (*.flac) echo %F
  
  echo was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%%F" in     (*.flac) echo %%F
  
  "%%F" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%f" in     (*.flac) echo %f
  
  "%f" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%g" in     (*.flac) echo %g
  
  "%g" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%g" in     ("*.*") echo %g
  
  "%g" was unexpected at this time.
  
  
  
  C:\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy>for "%g" in     ("*.*") do echo %g
  
  "%g" was unexpected at this time.

  original batch file for FFMPEG

  cd "\Users\yt\Music\Joe Hisaishi (Classical Guitar) - Copy"
  
  echo in directory "%cd%"
  
  pause
  
  for "%%F" in ("*.flac") do (
  
  echo converting "%%F"
  
  "C:\Users\yt\Downloads\OtherApps\FFMPEG\bin\ffmpeg.exe" -i "%%F"     -codec:a libmp3lame -qscale:a 2 "%%~nF.mp3"
  
  echo del "%%F"
  
  )
  
  cd "%~dp0"
