VIDEO PROFILES:
    sync profiles with Firefogg, there should be base profiles for
        96p, 360p, 480p, 720p, 1080p for ogv and webm

FRAME extraction:
    - vlc hangs on some files, mpg but also some avis
    - ffmpeg decodes full video, so it takes to long extracting frames at the end
    - oxframe only support ogv and webm (adding av* as option might work)
    - mplayer seams to work. might be an issue installing/bundling it

FIREFOX integration:
   possible ways:
     - launch oxbackend on localhost and connect to it
     - way to add/configure backends + launch one localy
       adding folders in remote backends is a bit complicated
       beeing able to manage a backend remotely would be nice(security questions though)
       also makes it a bit more complicated, than again ideal for situations with
       media servers hosting the actuall videos and clients to access them
     - rewrite large parts in javascript + sqlite bundled with firefox (requires js subprocess to work)

TODO:
    add fields:
        make archive / file link via id?
        
        is extracted field enough or requires frames/video thingy

    cache location, should cache be inside of archive, home folder or whats a good default.
    must be a config option in
