This enables users to capture thumbnails and display them as a position preview when sliding through the seek bar. There are three separate implementations of the thumbnail previews feature:
-
DASH-IF thumbnail previews
-
Harmonic WebVTT thumbnail previews
-
HLS I-Frame thumbnail previews
DASH-IF thumbnail previews
This feature enables users to capture thumbnails from DASH VOD and LIVE streams. See (5.33.x) DASH-IF thumbnails.
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.
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. See (5.33.x) Harmonic WebVTT thumbnails example code.
HLS I-Frame thumbnail previews
Some HLS streams provide accompanying I-Frame tracks; the CONNECT Player can make use of these additional tracks for displaying thumbnails. See (5.33.x) HLS I-frame thumbnails.
