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 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.

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.

Properties recognized by the filename matcher

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
  container, format,
  videoCodec, audioCodec,
  audioChannels, screenSize,
  releaseGroup, website,
  cdNumber, cdNumberTotal,
  edition, other

Command-line usage

To have GuessIt try to guess some information from a filename, just run it as a command:

user@home:~$ python "Movies/Dark City (1998)/Dark.City.(1998).DC.BDRip.720p.DTS.X264-CHD.mkv"
For: Movies/Dark City (1998)/Dark.City.(1998).DC.BDRip.720p.DTS.X264-CHD.mkv
GuessIt found: {
    [1.00] "videoCodec": "h264",
    [1.00] "container": "mkv",
    [1.00] "format": "BluRay",
    [0.60] "title": "Dark City",
    [1.00] "releaseGroup": "CHD",
    [1.00] "screenSize": "720p",
    [1.00] "year": 1998,
    [1.00] "type": "movie",
    [1.00] "audioCodec": "DTS"

The numbers between square brackets indicate the confidence in the value, so for instance in the previous example, GuessIt is sure that the videoCodec is h264, but only 60% confident that the title is ‘Dark City’.

You can use the ‘-v’ or ‘–verbose’ flag to have it display debug information.

You can also run a ‘–demo’ mode which will run a few tests and display the results.

Guessit also allows you to specify the type of information you want using the -i or –info flag:

user@home:~$  python -i hash_md5,hash_sha1,hash_ed2k test/
For: test/
GuessIt found: {
    [1.00] "hash_ed2k": "ed2k://|file||44|1CA0B9DED3473B926AA93A0A546138BB|/",
    [1.00] "hash_md5": "e781de9b94ba2753a8e2945b2c0a123d",
    [1.00] "hash_sha1": "bfd18e2f4e5d59775c2bc14d80f56971891ed620"

Python module usage

The main entry points to the python module are the guess_video_info, guess_movie_info and guess_episode_info.

The guess_video_info function will try to autodetect the type of the file, either movie, moviesubtitle, episode or episodesubtitle.

Pass them the filename and the desired information type:

>>> import guessit
>>> guess = guessit.guess_movie_info('Movies/Dark City (1998)/Dark.City.(1998).DC.BDRip.720p.DTS.X264-CHD.mkv', info = ['filename'])
>>> print type(guess)
<class 'guessit.guess.Guess'>
>>> print guess
{'videoCodec': 'h264', 'container': 'mkv', 'format': 'BluRay', 'title': 'Dark City', 'releaseGroup': 'CHD', 'screenSize': '720p', 'year': 1998, 'type': 'movie', 'audioCodec': 'DTS'}
>>> print guess.nice_string()
    [1.00] "videoCodec": "h264",
    [1.00] "container": "mkv",
    [1.00] "format": "BluRay",
    [0.60] "title": "Dark City",
    [1.00] "releaseGroup": "CHD",
    [1.00] "screenSize": "720p",
    [1.00] "year": 1998,
    [1.00] "type": "movie",
    [1.00] "audioCodec": "DTS"

A Guess instance is a dictionary which has an associated confidence for each of the properties it has.

A Guess instance is also a python dict instance, so you can use it wherever you would use a normal python dict
