====vutils====
A collection of tools to maintain meta-info of video files.
It currently uses mplayer for gathering meta-info.

=====Dependencies=====
  * [[http://golang.org/doc/install.html|A healty Go environment]]
  * [[wp>SQLite]] 3
  * [[http://github.com/salviati/gosqlite3|Go interface for SQLite3]]

=====Database Format=====
vutils uses [[wp>SQLite]] v3 database to store the entries (via [[http://github.com/kuroneko/gosqlite3|gosqlite3]]). The benefits of using a light-weight and fast database outweighed the benefits of having a textual, custom DB. And SQLite, due to it's simplicity and popularity, seemed to be the best choice. So yes, you can't simply cat your video database file. But you can use [[http://www.manpagez.com/man/1/sqlite3/|sqlite3(1)]] to list the contents of the DB file, or [[http://sqlitebrowser.sourceforge.net|SQLite Browser]] under X.
=====Alternatives=====
[[wp>Beagle (software)|Beagle]] + [[http://www.kernel.org/pub/linux/kernel/people/rml/fuse/beaglefs/|BeagleFS]] offer a somewhat close and more generic solution. But it's kind of useless for my purposes, because it collects little none information about videos (except for the filename). If you have Beagle installed, you can run `beagle-query --keywords` for a list. I got this, for instance (using Beagle 0.3.9):

  Supported query keywords are:                                                                                                                                    
  inarchive            for Use 'inarchive:true' for files inside an archive.
