List specific files from a directory

I can't list a specific files of a directory passed as argument to a batch file.

The problem I am facing is that the pipe "|" character is not recognized, I used it to circumvent the dir command limitations that it can

dir /b *.avi *.mp4 *.mkv

within a directory, but as I am creating this batch file to execute after uTorrent, I need to pass the directory as argument.

Globally, what I am trying to do is to automatically convert files downloaded by uTorrent to AAC audio.

Here's the batch files content:

FOR /F "tokens=*" %%i IN ('dir %1 /b /A-D | findstr /I (avi mp4 mkv)') DO ffmpeg -i "%%~fi" -c:v copy -c:a aac -ac 2 "%%~di%%~pi%%~ni_aac%%~xi"

The pipe `|` character is not recognized

You would need to escape it as follows:

^|

There are some additional errors in your code:

Piping to findstr /I (avi mp4 mkv) doesn't work as findstr doesn't work that way. You don't need findstr or piping anyway.

If it did work you would have to also escape ( and ).

"%%~di%%~pi%%~ni_aac%%~xi" doesn't give the output file the extension .acc

Try the following:

pushd %1

FOR /F "usebackq tokens=*" %%i IN (`dir /b *.avi *.mp4 *.mkv`) DO (

  echo ffmpeg -i "%%~fi" -c:v copy -c:a aac -ac 2 "%%~di%%~pi%%~ni.aac" 

  )

PAUSE

popd

Remove the echo if you are happy with the modified ffmpeg command.

^ Escape character.

Adding the escape character before a command symbol allows it to be
treated as ordinary text.

When piping or redirecting any of these characters you should prefix
with the escape character: & < > ^ |

eg ^ ^& ^| ^> ^< ^^
