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)


EXTENSION api:
    oxff = OxFF() //is site is not allowed, ask if user wants to allow domaing to use oxff

    oxff.update() //check for new files, would be nicer if that would be somehow automatic and not needed

    oxff.archives() //return list of archive names

    //new archive
    archive = oxff.archive('name')
    archive.setLocation() //opens file dialog to set location of archive

    //get files
    archive.files()
    archive.files(since) //unixtimestamp, get new/deleted/... since

    //get info
    oxff.get(oshash) //retuns info
    //get media
    oxff.get(oshash, 'stills')   //retuns stills dict or None if not extracted
    oxff.get(oshash, '96p.webm') //returns video location or none if not extracted

    //extract media
    oxff.extract(oshash, 'stills')
    oxff.extract(oshash, '96p.webm')

    //questions
        - how to upload media to site? somehow make use of  Firefogg
        - could some of those requests take to long and require callbacks?

TODO:
    use api like approach as done in pand.do/ra backend code

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