Properties:

    • option
    • description
    • default
    • src string
    • the location to fetch the VTT formatted thumbnails from
    • https://thumbnails.bucket.example.com/video/121231.vtt

Example VTT response

the VTT files must be configured in the form of sprite-based thumbnails:

WEBVTT

00:00:00.000 --> 00:00:02.000
thumbnails.jpg#xywh=0,0,120,67

00:00:02.000 --> 00:00:04.000
thumbnails.jpg#xywh=120,0,120,67

00:00:04.000 --> 00:00:06.000
thumbnails.jpg#xywh=240,0,120,67

00:00:06.000 --> 00:00:08.000
thumbnails.jpg#xywh=360,0,120,67

00:00:08.000 --> 00:00:10.000
thumbnails.jpg#xywh=0,67,120,67

00:00:10.000 --> 00:00:12.000
thumbnails.jpg#xywh=120,67,120,67

This ensures the maximum responsiveness from the thumbnail tooltip by drastically reducing the number of HTTP requests that are required to show thumbnails.

Sample code

var api = flowplayer('#container', 
  { src        : "//edge.flowplayer.org/bauhaus.mp4"
  , title      : "Bauhaus"
  , thumbnails : {src: "https://flowplayer.com/thumbnails.vtt"}
  })
