GuessIt - a library for guessing information from video files.

Project description


GuessIt is a python library that tries to extract 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 only its filename. This matcher works with both movies and tv shows episodes.

For example, GuessIt can do the following:

$ python -m 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"


At the moment, the filename matcher is able to recognize the following property types:

[ title,                             # for movies and episodes
  series, season, episodeNumber,     # for episodes only
  date, year,                        # 'date' instance of
  language, subtitleLanguage,        # instances of guessit.Language
  country,                           # instances of guessit.Country
  container, format,
  videoCodec, audioCodec,
  videoProfile, audioProfile,
  audioChannels, screenSize,
  releaseGroup, website,
  cdNumber, cdNumberTotal,
  filmNumber, filmSeries,
  bonusNumber, edition,
  idNumber,                          # tries to identify a hash or a serial number

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 module installed, GuessIt can also analyze a subtitle file’s contents and detect which language it is written in.


Installing GuessIt is simple with pip:

$ pip install guessit

or, with easy_install:

$ easy_install guessit

But, you really shouldn’t do that.


The project website for GuessIt is hosted at ReadTheDocs. There you will also find the User guide and Developer documentation.

Please report issues via the bug tracker.


GuessIt is under active development, and contributions are more than welcome!

  1. Check for open issues or open a fresh issue to start a discussion around a feature idea or a bug. There is a Contributor Friendly tag for issues that should be ideal for people who are not very familiar with the codebase yet.
  2. Fork the repository on Github to start making your changes to the master branch (or branch off of it).
  3. Write a test which shows that the bug was fixed or that the feature works as expected.
  4. Send a pull request and bug the maintainer until it gets merged and published. :)
