To get information about each stream, call <strong><see cref="SharpDX.MediaFoundation.SourceReader.GetPresentationAttribute"/></strong> or <strong><see cref="SharpDX.MediaFoundation.SourceReader.GetNativeMediaType"/></strong>.</li> <li>If you will not need data from one of the streams, it is a good idea to deselect that stream. If the stream is selected, the media source might hold onto a queue of unread data, and the queue might grow indefinitely, consuming memory. </li> </ul><p>For an example of deselecting a stream, see Tutorial: Decoding Audio.</p><p>If a stream is deselected, the <strong><see cref="SharpDX.MediaFoundation.SourceReader.ReadSample"/></strong> method returns <strong>MF_E_INVALIDREQUEST</strong> for that stream. Other <strong><see cref="SharpDX.MediaFoundation.SourceReader"/></strong> methods are valid for deselected streams.</p><p>Stream selection does not affect how the source reader loads or unloads decoders in memory. In particular, deselecting a stream does not force the source reader to unload the decoder for that stream.</p><p>This interface is available on Windows?Vista if Platform Update Supplement for Windows?Vista is installed.</p>
