ECHO Transcoding %1
REM Here’s where the actual transcoding/conversion happens. The next line
REM fires off a command to VLC.exe with the relevant arguments:
CALL “C:\Program Files\VideoLAN\VLC\vlc” -I dummy -v %1 :sout=#transcode{vcodec=none,acodec=mp3,ab=128,channels=2,samplerate=44100}:standard{access=”file”,mux=dummy,dst=”%_commanm%.mp3″} vlc://quit
REM Having no SLEEP-esque command, we have to trick DOS/Windows into pausing
REM for a bit between encode ops – To give the host OS a chance to do what it
REM needs to – Via clever use of the PING utility:
REM (Thanks to http://www.computing.net/answers/programming/dos-command-for-wait-5-seconds/11192.html for the tip! :-)

REM My own little addition to prevent the batch window from “vanishing” without
REM trace at the end of execution, as if a critical error had occurred.
