This method should only be called if the MediaStreamSource is below the desired buffering level. This method can be called multiple times between GetSampleAsync and ReportGetSampleCompleted; doing so updates the BufferingProgress property on the MediaElement. When buffering is completed, developers must call ReportGetSampleCompleted with the next sample.
For more information, see the “Buffering Management” section in Implementing MediaStream Sources.
StateTransitions: Calling this method allows the MediaElement to transition to the Buffering state, if it is in the Playing state, and will pause rendering. The behavior of the MediaElement is not defined if there are no outstanding GetSampleAsync requests when this method is called.
Silverlight for the desktopSilverlight desktop may transition to Buffering from the Paused state as well. Developers should also report 100% progress prior to exiting buffering.
Silverlight for Windows PhoneOn Windows Phone, the transition to Buffering may not occur immediately if the media pipeline has a sufficient quantity of samples still available to it. Developers do not need to report 100% progress prior to exiting buffering, as completing a sample does this automatically.
For a list of the operating systems and browsers that are supported by Silverlight, see Supported Operating Systems and Browsers.
