Michael S. Scherotter explains how to implement the thumbnail preview while scrubbing in a Silverlight video player.
One of the developers from one of my media customers asked me how
they would implement the thumbnail preview while scrubbing in a
Silverlight video player. He was turned onto the idea from seeing that
feature in the Netflix Watch Instantly Silverlight player.
I thought that would be something that others could use, so I decided to use Silverlight Media Framework
player to demonstrate it. It turns out that Expression Encoder has the
capability to create thumbnail images from a video during encoding.
You can use this capability to just create images of a video at regular
intervals.
