Psst. Open beta.

Wow, didn't really expect you to read this far down. The latest iteration of the site is in open beta. It's a gentle open beta-- not in prime-time just yet. It's being hosted over at UpGuard (link) and you are more than welcome to give it a shot. Couple things:

  • » The open beta is running a copy of the database that will not carry over to the final version. Don't post anything you don't mind losing.
  • » If you wish to use your user account, you will probably need to reset your password.
Your feedback is appreciated via the form on the beta page. Thanks! -Jon & CLFU Team

Get the total length of all video / audio in the current dir (and below) in H:m:s

change the *.avi to whatever you want to match, you can remove it altogether if you want to check all files.

Alternatives

There is 1 alternative - vote for the best!

Terminal - Alternatives
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}'

You're behind on your TV catch-up, but how far behind? This command tries to open mplayer against all files in the current dir. If it's a video file it will contain ID_LENGTH, which is summed and output in hours, minutes and seconds.

Someone better at awk could probably reduce this down a lot.

mplayer -endpos 0.1 -vo null -ao null -identify *.avi 2>&1 |grep ID_LENGTH |cut -d = -f 2|awk '{SUM += $1} END { printf "%d:%d:%d\n",SUM/3600,SUM%3600/60,SUM%60}'

Better awk example, using only mplayer, grep, cut, and awk.

find -type f -iregex '.*\.\(mkv\|mp4\|wmv\|flv\|webm\|mov\|dat\|flv\)' -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

Use case insensitive regex to match files ending in popular video format extensions and calculate their total time. (traverses all files recursively starting from the current directory)

Know a better way?

If you can do better, submit your command here.

What others think

Is there a good way to do this with audio? Gonna be working on that myself...

same command will work with anything mplayer will read, video or audio (just change the find options):

find -type f -name "*.mp3" -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

Comment by syssyphus 360 weeks and 6 days ago

you can remove the last part "|tail -n 1" and it will kinda give you an indication of progress.
