Chapter Marker, JW Player 6 Cloud and Streaming Engine not working

Hi all,

I pay for the Premium JW Player to support Cupertino streaming. I’ve got a long video that I wanted to add chapter markers to. I’ve got the chapter markers to appears but the time codes in the VTT aren’t matching up correctly in the video stream.

My VTT file (UTF-8) looks like the below. It’s saved as chapters.vtt and is in the same directory as the HTM file that hosts the player embed code.

Chapter 1
00:00:00.000 --> 00:31:27.190
Opening & Overview
Chapter 2
00:31:27.190 --> 00:40:07.230
Memory & Aging Project Satellite
Chapter 3
00:40:07.230 --> 00:56:07.190
DUO Program
Chapter 4
00:56:07.190 --> 01:05:57.160
Sleep and Alzheimer Disease
Chapter 5
01:05:57.160 --> 01:15:25.160
Advances in Imaging
Chapter 6
01:15:25.160 --> 01:36:01.160
Clinical Trials
Chapter 7
01:36:01.160 --> 01:42:47.230
Disclosure Study
Chapter 8
01:42:47.230 --> 02:15:47.040

The video is located here:

Any suggestions?

Problem resolved. I had a typo in my VTT jacking my numbers up. I blame lack of sleep :slight_smile:

Thanks for the update.

Welcome @Muhammad_Ahmad2, I’m not sure, you might have to scan the JW player docs for this.

Saw this though if it’s helpful: Go to #3 add chapters in JW Player
