If you have direct access to the media stream, you can use this overload of SetSource() to achieve the same effect as setting MediaElementSource property This recipe uses the second overload of the MediaElementSetSource() method, which accepts an instance of type SystemWindowsMediaMediaStreamSource The MediaStreamSource type is the extensibility mechanism that lets you build your own managed decoder and plug it into the Silverlight media pipeline We look at the MediaStreamSource API in more details in the next section It is important to note that authoring parsers for media file containers or decompression logic for various compression schemes is a specialized task; a lot of care and very skillful engineering are required to produce something that meets the bar for performance and quality Not doing it properly can result in low-performing and, in some cases, faulty processing of media.

When the user clicks a row in the grid, this popup component will open, and the onOpen event listener will be triggered to invoke the win.whenPopup(event) method, as shown in Listing 6-31. After that, evt.getReference() retrieves the component ( label component) that invoked the onOpen event and gets information about the pet from a item attribute defined in its parent component (row component). Then, an item variable is stored in an arg HashMap. The last step is to invoke Executions.createComponents() to create the components defined

Our goal in this recipe is not to make you an expert in doing either task, but rather to familiarize you with the API for the related extensibility mechanism in Silverlight If you take advantage of this facility to integrate a natively unsupported media format into your Silverlight code, we advise you to research the compression and container structure specifications for that format rigorously and apply best-of-breed engineering resources to building the parsing and the decompression logic..

System.Windows.Media.MediaStreamSource is an abstract class that expresses the interaction between the MediaElement and a managed decoder in an abstract API. It lets you create your own concrete type by inheriting from MediaStreamSource and providing implementations for the abstract API to inject custom media decoding logic into the Silverlight media pipeline. When you call MediaElement.SetSource() and pass in an instance of your concrete MediaStreamSource implementation, MediaElement interacts with your code to consume the media. The MediaStreamSource API is designed to be asynchronous so as to not block the UI thread on calls coming in through the MediaElement. As a result, every abstract method that you implement in your inherited class has a Report<methodname>Completed() method defined in the MediaStreamSource base class.

The goal is to return from the implementation of your method as quickly as possible to stop holding up the UI, and then, when you are ready with the results of the requested operation, to call the Report<methodname>Completed() method to signal the completion of the operation to the MediaElement This allows you to spin up asynchronous operations on separate threads from within your MediaStreamSource-derived class and process long-running operations in a nonblocking fashion As an example, consider the MediaStreamSourceOpenMediaAsync() method The following snippet shows a possible skeletal implementation: protected override void OpenMediaAsync() { //spin up a thread to process Thread thdOpen = new Thread(new ThreadStart(() => { //process the request - may take some time //when done ReportOpenMediaCompleted(.,.); })); thdOpenStart(); //return to MediaElement right away - no blocking return; } You create a thread and start it, and then return from the call right away.

But in the thread s processing logic, after you are ready with the results of the operation, you call ReportOpenMediaCompleted() to signal back to the MediaElement that you are finished This is an important point to keep in mind No hard-and-fast rule dictates what has to be done asynchronously and what does not In the previous snippet, you might have done all the processing in the call in a blocking fashion and then signaled completion before you returned, broken up the processing between the blocking call and the separate thread in some fashion, or done it entirely in an asynchronous fashion as the snippet shows in this case You make that decision based on the scenario for which you are implementing the MediaStreamSource.
