If you have watched any of my videos, then being able to speed them up is a great idea, now if there was only a way to get rid of the ummmmmmmmms.

How do you do that?

Silverlight.NET

  • Normally you would go to http://silverlight.net and expect to type in “TrickPlay” or MediaElement to get a search result with a cool video, but not in this case, for TrickPlay, you can skip it for the MediaElement.  The videos appear to discuss, and there is a Spanish video on the use of MediaElement in Silverlight 4

MSDN does have a two solid articles:

Discussion

You can do TrickPlay with no code behind, I downloaded an MP4 video from Channel 9, change the line under the MediaElement Source=”demo.mp4” to the name of the video you want to use in your example.

Naturally you can use code behind, but I wanted to make this a simple and easy blog for you to enjoy! image
