Doesn't correctly parse some youtube vtt subtitles #1

Open joegesualdo opened 7 years ago

Problem

Doesn't correctly parse

Why

Instead of separating words by the caption time, some youtube vtt subtitles separates by syllables.

Example

I have the same problem, the time is not working:

index.js

const vttToJson = require("vtt-to-json")
const vttString = `
00:00:40.790 --> 00:00:40.800 align:start position:0%
soms bij andere ploegen helemaal niets

00:00:40.800 --> 00:00:43.160 align:start position:0%
soms bij andere ploegen helemaal niets
iets<00:00:41.010><c> ik</c><00:00:41.399><c> kan</c><00:00:41.550><c> daar</c><00:00:41.760><c> enorm</c><00:00:42.210><c> van</c><00:00:42.390><c> genieten</c>
`;

vttToJson(vttString)
    .then((result) => {
        console.log(result.length)
        for(const component of result ) {
            console.log(component)
        }
    });

will output:

const output = 
{ start: 40790,
  end: 40800,
  part: 'soms bij andere ploegen helemaal niets',
  words:
   [ { word: 'soms', time: undefined },
     { word: 'bij', time: undefined },
     { word: 'andere', time: undefined },
     { word: 'ploegen', time: undefined },
     { word: 'helemaal', time: undefined },
     { word: 'niets', time: undefined } ] }
{ start: 40790,
  end: 40800,
  part: '',
  words: [ { word: '', time: undefined } ] }
