Windows 7 MediaElement

As you learn about the MediaElement in my past article Silverlight is able to do so using an embedded media player so that the client system does not need to have a player installed. This is a different approach from other media technologies. Adding media to a page is as simple as adding a MediaElement to your markup and providing a Uniform Resource Identifier (URI) to the media to play. You can interactively control media playback by using the Play, Pause, Stop and Volume controling methods of a MediaElement object.

Silverlight media support on Windows Phone is based on the native media stack used on Windows Phone 7 Series. Supported frame rates are typically lower than those available on desktop computers. MediaElement renders video at the original encoded resolution of the video, but you can override that by explicitly setting the Height,Width, and Stretch properties. Full screen mode is not supported on Windows Phone, but you can use the full screen to display video by setting the height and width of the MediaElement to the size of the application.

Example:

<phone:PhoneApplicationPage
