Silverlight: How to Display the Video from Webcams

Last Updated on Sunday, 2 September 2012 02:33 Written by Andrew Ivanov Thursday, 13 September 2012 12:00

In Silverlight, you can access the video and audio feeds from media devices such as webcams and TV tuners. This enables a number of scenarios, such as capturing and displaying images, uploading profile pictures to social networking applications, video diaries, audio diaries, audio note taking, augmented reality, and body gestures.

To set up a webcam in your Silverlight application, the first thing you need to do is get the available AudioCaptureDevices and VideoCaptureDevices on the system. CaptureDeviceConfiguration exposes a number of static members for getting all the available devices as well as getting the default devices. Once you have the device, you can associate it with a CaptureSource.

Silverlight: Server-Side Playlists with Arvixe Hosting

For Silverlight, a server-side playlist (SSPL) is a sequence of media assets (either audio or video) that allows server administrators to control the sequence of media viewed by users. This playlist can be created statically or dynamically. A server-side playlist used to serve media to Silverlight can be used only for streaming (either on-demand or broadcast); it cannot be used to serve downloaded media. Silverlight uses .wsx configuration files to specify an SSPL that can be served to the client via the MediaElement object. Some advantages of using an SSPL include the following:

1. Because the server seamlessly switches between the media files in a playlist, you can customize the viewer experience by combining multiple digital media files into what will appear to the end user to be a single content stream. This minimizes bandwidth spikes by decreasing the number of times that clients must connect to retrieve content.
2. When users connect to a site before a live broadcast has started, you can provide media that plays in a loop while users wait for the live broadcast to begin.

Silverlight: How to Use VideoBrush

Last Updated on Sunday, 2 September 2012 02:16 Written by Andrew Ivanov Friday, 7 September 2012 12:00

A VideoBrush paints an area with video. This topic describes how to use the Silverlight VideoBrush to paint shapes and text with video. It also provides examples that show how to interactively control a VideoBrush.

A VideoBrush is a type of Brush object similar to a LinearGradientBrush or an ImageBrush. However, instead of painting an area with a gradient or an image, it paints an area with video content. This video content is provided by a MediaElement. As with other brush types, you can use a VideoBrush to paint the Fill of a Rectangle, the Background of a Canvas, or the Foreground of a TextBlock. For more information about VideoBrush, see msdn.

To paint an area with video, you create a MediaElement and a VideoBrush and apply that VideoBrush to the object that you want to paint (see the following example).

Silverlight: How to Drag and Drop Objects in UI Layout

Last Updated on Sunday, 2 September 2012 02:06 Written by Andrew Ivanov Tuesday, 4 September 2012 12:00

The following example below shows how to drag and drop objects in a Silverlight-based application. For security reasons, you cannot drag and drop objects between applications. Therefore, it is more accurate to say that you “slide” objects within the Silverlight plug-in area. However, the term “drag and drop” is better known and therefore used here.
