Testing Hachoir, an open source metadata parser

Reading linuxfr.org, I found a new software, written in Python (it can then run on all -almost- platforms), that can extract very precious data from your files : metadata.
For example, running hachoir on an avi movie will tell you which container, video codec, audio codec, etc.. were used; the length, the framerate, etc… of the movie.
So, now that you want to test it, how can you install it on your (linux in this example) computer ?
Well, it depends on your distribution…
On Kubuntu (or Ubuntu), or Debian Sarge, I couldn’t install it, because of dependency problems, but if you want to give it a try, just add these 2 lines in your /etc/apt/sources.list :

deb http://plumbear.free.fr/debian etch main
deb-src http://plumbear.free.fr/debian etch main

, and :
#apt-get update
#apt-get upgrade
#apt-get install hachoir-parser hachoir-metadata

If it doesn’t work, don’t worry, you can install easily it using … easy_install !
#apt-get install easy_install
Almost done !
Juste type in:

#easy_install hachoir-parser
#easy_install hachoir-metadata

Easy isn’t it ?
To use it, it’s also very simple :

$ hachoir-metadata a_video_file.avi

  1. Super!
    A part que c’est « galère » pour l’installer (pas un simple apt-get), ça peut être utile (mais c’est quoi ce codec qui me manque pour lire ce film!).

    Ca me fait penser à GSpot (sous windows) qui fait la même chose (au moins pour les fichiers vidéo).
