Thumbnail previews
This enables users to capture thumbnails and display them as a position preview when sliding through the seek bar. There are two separate implementations of the thumbnail previews feature:
- DASH-IF thumbnail previews
- Harmonic WebVTT thumbnail previews
DASH-IF thumbnail previews
This feature enables users to capture thumbnails from DASH VOD streams.
Thumbnails have to be advertised in the DASH manifest as per DASH-IF Interoperability Points 4.3. Please refer to chapter 6.2.6 Tiles of thumbnail images for the details.
See DASH-IF thumbnails example code.
Harmonic WebVTT thumbnail previews
The Harmonic VOS interface enables users to capture thumbnails from DASH and HLS Live and VOD streams and display them as a position preview when sliding through the seek bar. Live StartOver, CatchUp and Long CatchUp are also supported.
