OSUBDL Fetch subs, senprobleme!
|
||||
===============================================================================
|
||||
|
||||
It's kind of annoying to visit OpenSubtitle's website.
|
||||
First off, their site's shit.
|
||||
Second off, it uses Javascript.
|
||||
|
||||
Let's get around that.
|
||||
With `osubdl`, you can download subtitles for a given file in the
|
||||
given language "automagically"~
|
||||
|
||||
|
||||
|
||||
----------------------------------------
|
||||
PRE-REQUISITES
|
||||
----------------------------------------
|
||||
You'll need:
|
||||
* To compile "oshash.h" to "oshash" and put it in your $PATH
|
||||
* a POSIX-compatible shell (tested with `pdksh` and `bash`)
|
||||
* "unzip" installed
|
||||
* "curl" installed"
|
||||
* Some videos <3
|
||||
|
||||
|
||||
|
||||
----------------------------------------
|
||||
USAGE
|
||||
----------------------------------------
|
||||
Just run "osubdl" like so:
|
||||
|
||||
osubdl file [language] [destination]
|
||||
|
||||
The file should be, obviously, some TV episode or movie's video file.
|
||||
The language defaults to "eng" (english), but you can choose any
|
||||
three-char language code.
|
||||
The destination defaults to the file's name, but with "srt" as the
|
||||
file-extension.
|
||||

||||
