• batch store %%f as variable

  22 juin 2017, par RyanMe321

  I’ve been trying to use %%f to operate a script on each file in a directory however however when referencing it through the script the %%f and %% nf don’t seem to be working. I’ve limited programming experience I’m trying to make a more useful version of this video formatting tutorial.

  So I’d like to store %%f and %% nf as variables to reference for the rest of the script though I can’t work out how.

  @echo off
  
  set /p FORMAT="Enter File Format: "
  
  FOR %%f IN (*.%FORMAT%) DO  echo %%f
  
  set TEST=%%f
  
  echo %TEST%
  
  cmd/k

  If I could store these it would resolve my issue, however this is the longer form of what I’m trying to do, this script works if I have the user enter the file manually into a variable (%VIDEO%=%%f and % nf). Though this is far from ideal.

  @echo off
  
  set /p FORMAT="Enter File Format: "
  
  
  
  FOR %%f IN (*.%FORMAT%) DO (
  
  ::IDFILE
  
  for /F "delims=" %%I in ('C:\ffmpeg\bin\ffprobe.exe -v error -show_entries format^=filename -of default^=noprint_wrappers^=1:nokey^=1 "%%f"') do set "FILENAME=%%I"
  
  
  
  for /F "delims=" %%I in ('C:\ffmpeg\bin\ffprobe.exe -v error -select_streams v:0 -show_entries stream^=codec_name -of default^=noprint_wrappers^=1:nokey^=1 "%%f"') do set "Vcodec=%%I"
  
  
  
  for /F "delims=" %%I in ('C:\ffmpeg\bin\ffprobe.exe -v error -select_streams a:0 -show_entries stream^=codec_name -of default^=noprint_wrappers^=1:nokey^=1 "%%f"') do set "Acodec=%%I"
  
  
  
  echo %FILENAME% is using %Vcodec% and %Acodec% codecs
  
  
  
  if %Vcodec% == h264 (echo DO NOT CONVERT VIDEO) else (echo CONVERT VIDEO) 
  
  if %Acodec% == ac3 (echo DO NOT CONVERT AUDIO) else (echo CONVERT AUDIO)
  
  timeout /t 5
  
  
  
  :: COPY V FIX A
  
  if %Vcodec% == h264 if not %Acodec% == ac3 (echo Copying Video, Converting Audio
  
  timeout /t 5
  
  C:\ffmpeg\bin\ffmpeg.exe -i "%%f" -map 0 -vcodec copy -scodec copy -acodec ac3 -b:a 640K "%%~nf"-AC3.mkv)

  avformat/mpegtsenc : Don't use heap allocated array to store pids
  A temporary heap array currently stores pids from all streams.  It is
  
  used to make sure there are no duplicated pids. However, this array is
  
  not needed because the pids from past streams are stored in the
  
  MpegTSWriteStream structs.
