How to integrate with VTT files

[MiladFaridnia]

I have vtt file that contains info about preview images:

`
01:43:40,000 --> 01:43:50,000
out02.jpg#xywh=292,120,146,60

01:43:50,000 --> 01:44:00,000
out07.jpg#xywh=438,120,146,60

01:44:00,000 --> 01:44:10,000
out03.jpg#xywh=584,120,146,60

01:44:10,000 --> 01:44:20,000
out03.jpg#xywh=730,120,146,60

01:44:20,000 --> 01:44:30,000
out07.jpg#xywh=876,120,146,60
`
ass you see each part of that contains info about preview image and its position.

How can I integrate this vtt file with PreviewSeekBar.
I saw your samples. It seems PreviewSeekBar takes one thumbnail URL to work with, But as you see I have a list of thumbnails in my vtt file.
