I have used MediaInfo before to extract information in a shell script in CygWin.
#!/bin/bash
IFS=$'\n'; for file in $(ls *.mp3 /.mp3 ); do count="C:/Program Files/MediaInfo/MediaInfo.exe" $file | grep "Bit rate mode" | grep "Variable" | wc -l
; if [ $count -gt 0 ]; then echo $file VBR; fi done
For some reason, it no longer outputs to stdout. It displays the data in a window. Is there some command line flag tp force stdout?
