Batch script convert to MP3 with troublesome filenames: apostrophe, comma, ampersand etc.
Posted: 31 Aug 2021 20:12
Batch script processing with VLC runs into trouble converting files which contain commas, apostrophes, ampersands, and other symbols in their filenames:
I finally said enough is enough, and decided to figure this out once and for all. The best method I've found is to use a temporary filename and rename it after VLC is done converting. So here's the batch script I use to convert FLAC to MP3, which will also copy the FLAC tags to the MP3's ID3 tags if ffmpeg is installed:
Save it as a batch file (ie. "Convert-to-MP3.bat") and read the *** remarks. Then you can drag and drop one or more FLAC files on it to convert them to MP3s. This script is pretty easy to understand so that it can be revised to work with other conversions. I apologize that I didn't keep track of where I got some of these ideas and so I can't credit the proper people.
I hope this will be helpful!

PS If you have ffmpeg installed, you could just leave VLC out entirely, and no need to worry about those pesky symbols:
Cross-posted to Reddit/vlc
- The resulting filename might be truncated at the troublesome character:
"Having My Cake & Yeeting It Too.flac" becomes
"Having My Cake "
Or in some circumstances extra characters from the batch script appear after the file extension:
"Troublesome Filename.mp3}"

Code: Select all
REM ---- Loop for each file ----
FOR %%A IN (%*) DO (CALL :SUB_VLC %%A)
REM *** In the event of errors, remove below REM to keep the console window open after processing:
REM PAUSE
GOTO :eof
:SUB_VLC
REM Note: _TEMP_A.mp3 will be overwritten by VLC if it exists
REM ---- Convert file to MP3 with VLC at 192kbps ----
REM *** Update path to VLC.exe if needed, and change 192 to 320 if desired
"C:\Program Files (x86)\VideoLAN\VLC\vlc.exe" -I dummy %1 --sout=#transcode{acodec=mp3,ab=192,vcodec=dummy}:standard{access=file,mux=raw,dst="_TEMP_A.mp3"} vlc://quit
REM ---- Copy FLAC tags to MP3 ID3 tags ----
REM *** ffmpeg must be installed. If it doesn't run from this script, it probably isn't "on the PATH". Either you will need to replace "ffmpeg" with the path to ffmpeg.exe (use quotes around the path if it contains spaces) *OR* add ffmpeg to the PATH System Variable.
ffmpeg -y -i %1 -map_metadata 0 -id3v2_version 3 "%~dp1_TEMP_A.mp3"
REM ---- Rename file ----
SET _outfile="%~n1.mp3"
REN "%~dp1_TEMP_A.mp3" %_outfile%
GOTO :eof
