I just posted an update to the code I wrote almost a year ago for showing thumbnail images of a video while scrubbing (moving the play slider) in Silverlight. This is similar to the experience that you get when scrubbing on Netflix Watch Instantly with Silverlight. Here is what I’ve done:
- I updated the code for Silverlight 4.
- I updated the code for the Silverlight Media Framework 2.2 release by making the code a plug-in. This makes it very easy to integrate the code – all you have to do is add the ThumbnailScrubbing.dll assembly to your project and the SMF Framework takes care of it with the Managed Extensibility Framework (MEF).
- I added a GenerateThumbnails command line tool that uses the Expression Encoder 4 object model to generate the necessary thumbnail images.
- The Thumbnails control is now a custom control that can be styled or skinned.
