subtitle.js


Parse and manipulate SRT (SubRip) format.

Installation

npm install subtitle --save

Usage

``javascript
var Subtitle = require('subtitle');

var captions = new Subtitle();

captions.parse('your srt here');

console.log(captions.getSubtitles());

`

It's gonna return an array like this:

`javascript
[
{
index: 1,
start: '00:00:20,000',
end: '00:00:24,400',
text: 'Bla Bla Bla Bla'
},
{
index: 2,
start: '00:00:24,600',
end: '00:00:27,800',
text: 'Bla Bla Bla Bla'
}
]
`

You can also pass options to the getSubtitles() method.

`javascript
captions.getSubtitles({
duration: true, // Include the duration property
timeFormat: 'ms' // Set time format to milliseconds
});
`

Here's the result:

`javascript
[
{
index: 1,
start: 20000,
end: 24400,
duration: 4400,
text: 'Bla Bla Bla Bla'
},
{
index: 2,
start: 24600,
end: 27800,
duration: 3200,
text: 'Bla Bla Bla Bla'
}
]
`

You can also add new captions.

`javascript
var captions = new Subtitle();

captions.add({
start: '00:00:20,000',
end: '00:00:21,900',
text: 'Text here'
});

// You can use time in MS if you prefer
captions.add({
start: 22000,
end: 22580,
text: 'Another text here...'
});
`

And what about resync your captions?

`javascript
// Advance 1s
captions.resync(1000);

// Delay 500ms
captions.resync(-500);
`

Then, you can stringfy your changes:

`javascript
captions.stringfy(); // Returns a valid SRT
`

Tests
