opensubtitles-api

OpenSubtitles.org API wrapper for downloading and uploading subtitles, helping to communicate with the OpenSubtitles XML-RPC API using Node.js

In addition of allowing to use all available methodCalls asynchronously, it also allows you to directly use powerfull custom calls, like:

• search: Chained function returning the best matching subtitles based on the information you can feed it.
• upload: Chained function requiring only the path to the video and to the subtitle files to send new subtitles to OpenSubtitles.org (flow: LogIn > TryUploadSubtitles > UploadSubtitles)
• hash: Function returning Hash and Byte size for a given video
• md5: Function returning Hash for a given subtitle
• identify: Chained function returning metadata based on video file hash

Read index.js for more info on the custom calls.

More complete docs are available.

This module requires a valid UserAgent.

Quick start

npm install opensubtitles-api

Then:

const OS = require('opensubtitles-api');
const OpenSubtitles = new OS({
    useragent:'UserAgent',
    username: 'Username',
    password: 'Password',
    ssl: true
});

You can omit username and password to use OpenSubtitles.org anonymously (not all methods are available)

You can omit the endpoint to use HTTP default OpenSubtitles API endpoint: http://api.opensubtitles.org:80/xml-rpc

SSL: default value is 'false', set to true to use https. This parameter gets overwritten by any custom endpoint

NOTE: 'Password' can be a MD5 encrypted string, OpenSubtitles accept these. It is recommended to use it. You can get the MD5 of a PASSWORD string by doing: require('crypto').createHash('md5').update(PASSWORD).digest('hex');

Examples:

A simple login:

OpenSubtitles.login()
    .then(res => {
        console.log(res.token);
        console.log(res.userinfo);
    })
    .catch(err => {
        console.log(err);
    });

NOTE: The login() call is useful to verify "Username" and "Password" (if you get a token, you're authentified, as simple as that), but is never needed for the custom calls (search, upload), they're made by the module itself. If you use raw xml-rpc call (OpenSubtitles.api.methodCall), prefer to login with the raw OpenSubtitles.api.LogIn

Get in touch with OpenSubtitles.org API directly:

Example :

const OS = require('opensubtitles-api');
const OpenSubtitles = new OS('UserAgent');

OpenSubtitles.api.LogIn('username', 'password', 'en', 'UserAgent').then...

Search the best subtitles in all languages for a given movie/episode:

OpenSubtitles.search({
    sublanguageid: 'fre',       // Can be an array.join, 'all', or be omitted.
    hash: '8e245d9679d31e12',   // Size + 64bit checksum of the first and last 64k
    filesize: '129994823',      // Total size, in bytes.
    path: 'foo/bar.mp4',        // Complete path to the video file, it allows
                                //   to automatically calculate 'hash'.
    filename: 'bar.mp4',        // The video file name. Better if extension
                                //   is included.
    season: '2',
    episode: '3',
    extensions: ['srt', 'vtt'], // Accepted extensions, defaults to 'srt'.
    limit: '3',                 // Can be 'best', 'all' or an
                                // arbitrary nb. Defaults to 'best'
    imdbid: '528809',           // 'tt528809' is fine too.
    fps: '23.96',               // Number of frames per sec in the video.
    query: 'Charlie Chaplin',   // Text-based query, this is not recommended.
    gzip: true                  // returns url to gzipped subtitles, defaults to false
}).then(subtitles => {
    // an array of objects, no duplicates (ordered by
    // matching + uploader, with total downloads as fallback)

    subtitles = Object {
        en: {
            downloads: "432",
            encoding: "ASCII",
            id: "192883746",
            lang: "en",
            langName: "English",
            score: 9,
            url: "http://dl.opensubtitles.org/download/subtitle_file_id",
            filename: "some_movie.tag.srt"
        }
        fr: {
            download: "221",
            encoding: "UTF-8",
            id: "1992536558",
            lang: "fr",
            langName: "French",
            score: 6,
            url: "http://dl.opensubtitles.org/download/subtitle_file_id",
            filename: "some_movie.tag.srt"
        }
    }
});

NOTE: No parameter is mandatory, but at least one is required. The more possibilities you add, the best is your chance to get the best matching subtitles in a large variation of languages. I don't recommend ever using "query", as it is highly error-prone. *sublangageid is a 3 letters langcode (ISO 639-2 based)

Here's how the function prioritize:

1. Hash + filesize (or Path, that will be used to calculate hash and filesize)
2. Filename
3. IMDBid (+ Season and Episode for TV Series)

The function internally ranks the subtitles to get the best match given the info you provided. It works like this:

matched by 'hash' and uploaded by:
    + admin|trusted     12
    + platinum|gold     11
    + user|anon         8

matched by tag and uploaded by:
    + admin|trusted     11
    + platinum|gold     10
    + user|anon         7

matched by imdb and uploaded by:
    + admin|trusted     9
    + platinum|gold     8
    + user|anon         5

matched by other and uploaded by:
    + admin|trusted     4
    + platinum|gold     3
    + user|anon         0

bonus of fps matching if:
    + nothing matches   2
    + imdb matches      0.5

Upload a subtitle:

OpenSubtitles.upload({
        path: '/home/user/video.avi',       // path to video file
        subpath: '/home/user/video.srt'     // path to subtitle
    })
    .then(status => {
        status = Object {
            status: '200 OK'
            data: 'http://www.opensubtitles.org/subtitles/123456' //absolute link to subtitles
            seconds: '1.171'
        }
    })
    .catch(console.error);

NOTE: Only subpath is mandatory. However, it is highly recommended to also provide path and imdbid to make sure you can add a subtitle even if the movie isn't already in the database.

Optionnal parameters are self-explanatory:

• sublanguageid // subtitle is in which language?
• highdefinition // is for HD versions
• hearingimpaired // subtitle contains written description of sounds
• moviereleasename // title of the release, usually the filename without extension
• movieaka // alternate title, for example in another language
• moviefps // frames par second
• movieframes // total number of frames in the video
• movietimems // total duration in milliseconds
• automatictranslation // the subtitle was translated by a machine, eg. Google Translate
• subauthorcomment // commentary from the author
• subtranslator // subtitle was translated by?
• foreignpartsonly // subtitle only contains translation for non-native language, example: only the elvish and Ork in 'The Lord of the Ring', not the english.

Use gzipped subtitles:

Using gzipped subtitles can reduce load on opensubtitles and enhance everyone's experience.

Example: download the best matching subtitle in french, unzip it and display the subtitle.

const OpenSubtitles = require('opensubtitles-api');
const OS = new OpenSubtitles('OSTestUserAgent');
OS.search({
    imdbid: 'tt0314979',
    sublanguageid: 'fre',
    gzip: true
}).then(subtitles => {
    if (subtitles.fr) {
        console.log('Subtitle found:', subtitles);
        require('request')({
            url: subtitles.fr.url,
            encoding: null
        }, (error, response, data) => {
            if (error) throw error;
            require('zlib').unzip(data, (error, buffer) => {
                if (error) throw error;
                const subtitle_content = buffer.toString(subtitles.fr.encoding);
                console.log('Subtitle content:', subtitle_content);
            });
        });
    } else {
        throw 'no subtitle found';
    }
}).catch(console.error);

Extract Hash & MovieByteSize

OpenSubtitles.hash('path/to/file.mp4')
    .then(infos => {
        infos = Object {
            moviehash: 'b6e2dab8fc092977'
            moviebytesize: '424954701'
        }
    });

Get metadata from Hash

OpenSubtitles.identify({
        path: 'C:\video\file.mp4',
        extend: true
    })
    .then(data => {
        data = Object {
            added: false
            metadata: Object {
                cast: Object {}
                country: Array[1]
                cover: "http://link-to-image/pic.jpg"
                directors: Object {}
                duration: "82 min"
                genres: Array[4]
                imdbid: "tt0997518"
                rating: "6.5"
                synopsys: "the story about a man sitting in his appartment"
                title: "Potiche"
                year: "2006"
            }
            moviebytesize: "518064188"
            moviehash: "a91cf276aaa6bf20"
            subcount: "38"
            type: "movie"
        }
    }

Notes:

If you're logging in anonymously by default and want to update the module with a username/password for the future, just throw in a new new OpenSubtitle({}) with the right object. Same thing to switch endpoint or http/https.
