subtitles-parser-vtt

Simple module written in javascript, which provides SubRip subtitles parsing methods

Installation:

NodeJS:

npm install subtitles-parser-vtt

Example

Let's say we have my.srt SubRip subtitles file:

1
00:00:02,000 --> 00:00:06,000
Subtitle 1.1
Subtitle 1.2

2
00:00:28,967 --> 01:30:30,958
Subtitle 2.1
Subtitle 2.2

1. Load file into data variable

var fs = require('fs');
var parser = require('subtitles-parser-vtt');

var srt = fs.readFileSync('my.srt','utf8');

var data = parser.fromVtt(srt);

data object will look like:

[{
    id: '1',
    startTime: '00:00:02,000',
    endTime: '00:00:06,000',
    text: 'Subtitle 1.1\nSubtitle 1.2'
},
{
    id: '2',
    startTime: '00:00:28,967',
    endTime: '01:30:30,958',
    text: 'Subtitle 2.1\nSubtitle 2.2'
}]

if you will pass true flag to fromVtt function:

var dataMs = parser.fromVtt(srt, true);

then it will convert startTime and endTime properties into millisecods:

[{
    id: '1',
    startTime: 2000,
    endTime: 6000,
    text: 'Subtitle 1.1\nSubtitle 1.2'
},
{
    id: '2',
    startTime: 28967,
    endTime: 5430958,
    text: 'Subtitle 2.1\nSubtitle 2.2'
}]

parser.toVtt() will convert object back to SubRip subtitles format.
