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
