Thumbnail previews
The CONNECT Player SDK can be configured to display preview thumbnails when you run your mouse pointer over the seek/progress bar. Currently, only WebVTT format thumbnails are supported.
To enable this feature, pass the URL of a WebVTT thumbnail resource to the otvtoolkit
.
playerInstance.otvtoolkit().addThumbnailPreview(thumbnailWebvttUrl);
The thumbnail preview must be added after setting the player source.
