• %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"

• Extracting Subtitles using FFMPEG (Unsupported subtitles codec : eia_608)

  The info for the input file is :

  And shows that stream #0:2 contains subtitles in eia_608 format. Using the following command to extract those subtitles into the output.srt file :

  ffmpeg -i cpcdemo.mov -map 0:2 -c:s copy output.srt

  We get the following output :

  It states that eis_608 is an unsupported codec, except I see that it’s listed as a supported codec under :

  ffmpeg -codecs

  Any possible reasons why this may be failing ?
