Sometime you may need to know to time duration of your multiple audio or video files. Here I am showing you to get the total length of all video/audio in the current directory in H:m:s. Change the file extension according to your need. This script will help you to get audio/video file length.
To Get Video File Length:
1 2 3 | $ find -type f -name "*.avi" -print0 | xargs -0 mplayer -vo dummy -ao dummy -identify 2>/dev/null | perl -nle '/ID_LENGTH=([0-9\.]+)/ && ($t +=$1) && printf "%02d:%02d:%02d\n",$t/3600,$t/60%60,$t%60' | tail -n 1 |
OR (Using mplayer):
1 2 3 | $ mplayer -vo dummy -ao dummy -identify * 2>&1 | grep ID_LENGTH | sed 's/.*=\([0-9]*\)/\1/' | xargs echo | sed 's/ /+/g' | bc | awk 'S=$1; {printf "%dh:%dm:%ds\n",S/(60*60),S%(60*60)/60,S%60}' |
To Get Audio File Length:
1 2 3 | $ find -type f -name "train/wav/*.wav" -print0 | xargs -0 mplayer -vo dummy -ao dummy -identify 2>/dev/null | perl -nle '/ID_LENGTH=([0-9\.]+)/ && ($t +=$1) && printf "%02d:%02d:%02d\n",$t/3600,$t/60%60,$t%60' | tail -n 1 |
