Build Status

This is a Golang client for Open Subtitles.

This project allows you to search and download subtitles from Open Subtitles. If you are only interested in searching or downloading then you should find what you need from the latest releases, otherwise the TODO section highlights what remains to be done regarding API coverage.

Installation

If you need (yet another) CLI interface for Open Subtitles, then install the latest Go release, and run:

go get github.com/oz/osdb && go install github.com/oz/osdb/cmd/osdb

Provided that you setup your Go environment correctly, you now have a basic osdb command to interact with OpenSubtitles' API.

$ osdb --help
Usage:
    osdb get [--lang=<lang>] <file>
    osdb (put|upload) <movie_file> <sub_file>
    osdb imdb <query>...
    osdb imdb show <movie id>
    osdb -h | --help
    osdb --version

Hence, to download French or English subtitles for a sample file:

$ osdb get --lang fra,eng sample.avi
- Getting fra subtitles for file: sample.avi
- No subtitles found!
- Getting eng subtitles for file: sample.avi
- Downloading to: sample.srt

Hack...

The generated documentation for this package is available at: http://godoc.org/github.com/oz/osdb

To get started...

  • Install with go get -d github.com/oz/osdb,
  • and import "github.com/oz/osdb" in your Go code,
  • or try some of the examples in the README.

To access the OpenSubtitles' XML-RPC server you first need to allocate a client, and then use it to login (even anonymously) in order to receive a session token. With that, you are finally be allowed to talk. Here is a short example:

package main

import "github.com/oz/osdb"

func main() {
	c, err := osdb.NewClient()
	if err != nil {
		// ...
	}

	// Anonymous login will set c.Token when successful
	if err = c.LogIn("", "", ""); err != nil {
		// ...
	}

	// etc.
}

Basic examples

Getting a user session token

Although this library tries to be simple, to use OpenSubtitles' API you need to login first so as to receive a session token: without it you will not be able to call any API method.

c, err := osdb.NewClient()
if err != nil {
	// ...
}

if err = c.LogIn("user", "password", "language"); err != nil {
	// ...
}
// c.Token is now set, and subsequent API calls will not be refused.

However, you do not need to register a user. To login anonymously, just leave the user and password parameters blank:

c.LogIn("", "", "")

Searching subtitles

Subtitle search can be done in a number of ways: using special file-hashes, IMDB movie IDs, or even using full-text queries. Hash-based search will generally yield the best results, so this is what is demoed next. However, in order to search with this method, you must have a movie file to hash.

path := "/path/to/movie.avi"
languages := []string{"eng"}

// Hash movie file, and search...
res, err := client.FileSearch(path, languages)
if err != nil {
	// ...
}

for _, sub := range res {
	fmt.Printf("Found %s subtitles file \"%s\" at %s\n",
		sub.LanguageName, sub.SubFileName, sub.ZipDownloadLink)
}

Downloading subtitles

Let's say you have just made a search, for example using FileSearch(), and as the API provided a few results, you decide to pick one for download:

subs, err := c.FileSearch(...)

// Download subtitle file, and write to disk using subs[0].SubFileName
if err := c.Download(&subs[0]); err != nil {
	// ...
}

// Alternatively, use the filename of your choice:
if err := c.DownloadTo(&subs[0], "safer-name.srt"); err != nil {
	// ...
}

Checking if a subtitle exists

Before trying to upload an allegedly "new" subtitles file to OSDB, you should always check whether they already have it.

As some movies fit on more than one "CD" (remember those?), you will need to use the Subtitles type (note the s?), one per subtitle file:

subs := osdb.Subtitles{
		{
			SubHash:       subHash,       // md5 hash of subtitle file
			SubFileName:   subFileName,
			MovieHash:     movieHash,     // see osdb.Hash()
			MovieByteSize: movieByteSize, // careful, it's a string...
			MovieFileName: movieFileName,
		},
}

Then simply feed that to HasSubtitles, and you will be done.

found, err := c.HasSubtitles(subs)
if err != nil {
	// ...
}

Hashing a file

OSDB uses a custom checksum-hash to identify movie files. If you ever need these:

hash, err := osdb.Hash("somefile.avi")
if err != nil {
	// ...
}
fmt.Println("hash: %x\n", hash)

On user agents...

If you have read OSDB's developer documentation, you should notice that you need to register an "official" user agent in order to use their API.

By default this library will present itself with the "osdb-go" agent, which is fine for me. However, if you need to change this, simply set the client's UserAgent with:

c, err := osdb.NewClient()
if err != nil {
	// ...
}
c.UserAgent = "My custom user agent"

A Subtitle with its many OSDB attributes...

func NewSubtitleWithFile 

func NewSubtitleWithFile(movieFile string, subFile string) (s Subtitle, err error)

	ID       string `xmlrpc:"idsubtitlefile"`
	Data     string `xmlrpc:"data"`

SubtitleFile contains file data as returned by OSDB's API, that is to say: gzip-ped and base64-encoded text.

func (*SubtitleFile) Reader 

func (sf *SubtitleFile) Reader() (r io.ReadCloser, err error)

Reader interface for SubtitleFile. Subtitle's contents are decompressed, and usually encoded to UTF-8: if encoding info is missing, no re-encoding is done.

type Subtitles 

type Subtitles []Subtitle

Subtitles is a collection of subtitles.

func (Subtitles) Best 

func (subs Subtitles) Best() *Subtitle

Best finds the best subsitle in a Subtitles collection. Of course "best" is hardly an absolute concept: here, we just take the most downloaded file.
