INTRODUCTION

Embedded media players video/audio represent the cornerstone components of modern rich internet applications RIA, extending the web page interactivity, responsiveness, aesthetic appeal and overall user experience. Adobe Flash implemented, for

example, in YouTube has tremendous installation base worldwide and currently dominates this sector of technology. At the same time, relatively new but rather promising technologies are actively penetrating the market of rich internet applications,

most notably: Microsoft Silverlight and HTML 5.0.

Silverlight provides extremely powerful RIA development platform, helping to bridge the gap between web applications and their desktop counterpart in terms of user experience and dynamic content streaming. As an example, the latest highly sophisticated

web-based HD video player, developed by Netflix, is built on the Silverlight technology set and is compatible with all major web browsers, including the most popular Internet Explorer and Firefox. Silverlight is backed by a full power

of Microsoft. NET technological framework and its sophisticated integrated development environment Visual Studio 2008/2010.

Silverlight Media Player, described in this article, implements application program interface API, written in C. It provides plenty of customization features, such as setting the auto-play options, adding chapters, dynamically changing

the visual styles so-called skins, etc.

PROJECT CONTAINS:

1. Default Web page Default.aspx with corresponding code behind: both to be placed in Application root directory ASP.NET 2.0

2. Silverlight Library file to be placed in Bin application directory

3. Ajax Library file AjaxControlToolkit.dll to be placed in Bin application directory

4. Player Styles Skin files xaml collection, placed in MediaPlayerSkins folder

5. Player Initial setting stored in XML document file SilverlightMediaPlayer.xml

6. Media Item data stored in XML document file SilverlightMediaItems.xml

7. Custom Silverlight Player XML reader/parser class library SilverlightPlayerLib.dll stored in Bin application directory

Available Styles include:

AudioGray Basic Classic Console Expression Futuristic Professional Simple

NEW. Also, check the new version of embedded YouTube Video player ASP.NET SDK written in C implementing the latest HTML5/CSS3 features click on the image below

Listing 1. Following Demo page contains all necessary components in order to run a Silverlight Media Player:

Listing 2. Following code snippets demonstrates the Media Player initial settings programming technique:

region Media Player initial settings

MediaPlayer1.AutoPlay true;

MediaPlayer1.ScaleMode System.Web.UI.SilverlightControls.ScaleMode.Zoom;

MediaPlayer1.MediaSource _source;

MediaPlayer1.PlaceholderSource _domain VIDEO/Demo/ImgMain.JPG ;

MediaPlayer1.Width 600;

MediaPlayer1.Height 440;

endregion

Listing 3. Chapters are added by the following coding pattern:

System.Web.UI.SilverlightControls.MediaChapter mc

new System.Web.UI.SilverlightControls.MediaChapter ;

mc.Position 18;

mc.ThumbnailSource ;

mc.Title Chapter1 ;

MediaPlayer1.Chapters.Add mc ;

mc null;

and the entire code behind page is looking as follows:

BETTER SOLUTION

Media Player initial settings and Media Item data could be stored in a separate XML documents files, namely: SilverlightMediaPlayer.xml and SilverlightMediaItems.xml. Corresponding custom XML reader/parser class library SilverlightPlayerLib.dll has been

added to the project placed in Bin application folder. The sample structure of the XML files are shown below:
