Identifies a subtitle type by its text and converts it to a JavaScript object.
Try Playground.
- vtt
- srt
- ass
- audacity (labels)
{
identifier: "1",
start: 0.498,
end: 2.827,
body: [ {text: "Hi, how are you?"} ]
}npm i frazy-parser
import { parseSubs } from 'frazy-parser'
const phrases = parseSubs(subsText)In any subs type you can use <v> tag. It is native only for vtt, but we support it for any format.
0.15 4.38 <v.loud.kindly John Doe> Hi everyone! How are you doing!?
will be converted to:
{
start: 0.15,
end: 4.38,
body: [
{
voice: {
name: 'John Doe',
classes: ['loud', 'kindly']
},
text: 'Hi everyone! How are you doing!?'
}
]
}As in a vtt format, a cue (phrase) can have several <v> tags. In that case you should use it with closing tag </v>.
You can see more examples in /tests/subtitles folder. For run tests:
npm test

Only two simplest schemes are supported:
-
Dialogue: 0,0:00:00.80,0:00:02.38,Default,,0,0,0,,text of cue -
0:00:00.80,0:00:02.38 text of cue
0:00:23.90,0:00:26.60 line one
0:00:27.83,0:00:32.03 line two
0:00:32.43,0:00:41.89 line three
0:01:01.15,0:01:04.45 line four
0:01:05.75,0:01:09.85 line five
The VTT format allows you to place, in addition to the main cues/phrases, additional information such as signature, chapters, comments. We provide parsing of that texts in a YAML-like way.

]In that way, you can use a valid VTT file as a data source for your app. And a comprehensive data structure will be extracted from the plain text, that is still a valid VTT file, and you can use it also as an ordinary caption/subtitle file.
