GuessIt is a python library that extracts as much information as possible from a video file.

It has a very powerful filename matcher that allows to guess a lot of metadata from a video using its filename only. This matcher works with both movies and tv shows episodes.

For example, GuessIt can do the following:

$ guessit "Treme.1x03.Right.Place,.Wrong.Time.HDTV.XviD-NoTV.avi"
For: Treme.1x03.Right.Place,.Wrong.Time.HDTV.XviD-NoTV.avi
GuessIt found: {
    [1.00] "mimetype": "video/x-msvideo",
    [0.80] "episodeNumber": 3,
    [0.80] "videoCodec": "XviD",
    [1.00] "container": "avi",
    [1.00] "format": "HDTV",
    [0.70] "series": "Treme",
    [0.50] "title": "Right Place, Wrong Time",
    [0.80] "releaseGroup": "NoTV",
    [0.80] "season": 1,
    [1.00] "type": "episode"
}

Installing GuessIt is simple with pip:

$ pip install guessit

or, with easy_install:

$ easy_install guessit

But, you really shouldn't do that.

You can now launch a demo:

$ guessit -d

and guess your own filename:

$ guessit "Breaking.Bad.S05E08.720p.MP4.BDRip.[KoTuWa].mkv"
For: Breaking.Bad.S05E08.720p.MP4.BDRip.[KoTuWa].mkv
GuessIt found: {
    [1.00] "mimetype": "video/x-matroska", 
    [1.00] "episodeNumber": 8, 
    [0.30] "container": "mkv", 
    [1.00] "format": "BluRay", 
    [0.70] "series": "Breaking Bad", 
    [1.00] "releaseGroup": "KoTuWa", 
    [1.00] "screenSize": "720p", 
    [1.00] "season": 5, 
    [1.00] "type": "episode"
}

The filename matcher is based on regular expressions and tree splitting to guess values from input filename.

It is able to find many properties, like title, year, series, episodeNumber, seasonNumber, videoCodec, screenSize, language. Guessed values are cleaned up and given in a readable format which may not match the raw filename.

DVDSCR will be guessed as format = DVD + other = Screener.

1920x1080 will be guessed as screenSize = 1080p.

DD5.1 will be guessed as audioCodec = DolbyDigital + audioChannel = 5.1.

GuessIt also allows you to compute a whole lof of hashes from a file, namely all the ones you can find in the hashlib python module (md5, sha1, ...), but also the Media Player Classic hash that is used (amongst others) by OpenSubtitles and SMPlayer, as well as the ed2k hash.

If you have the 'guess-language' python package installed, GuessIt can also analyze a subtitle file's contents and detect which language it is written in.

If you have the 'enzyme' python package installed, GuessIt can also detect the properties from the actual video file metadata.
