Hello,
how do I get the duration in a shell script? The following code does not always compute the correct value:
sumlen=0 for i in "$recdir"/0*.vdr ; do # length in sec. in ID_LENGTH ergebnis=$(/usr/local/bin/midentify "$i") eval $ergebnis sumlen=$(echo "scale=3 ; $sumlen + $ID_LENGTH" | bc) done echo $sumlen
(midentify is mplayer -vo null -ao null -frames 0 -identify "$@")
Can you tell me a correct way?
Thank you,
Dirk
