+Multimedia Framework sink/source plug-ins example</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<section><title>Description</title> <p> <filepath>MmfExSinkSource</filepath> demonstrates
+how to implement sink and source plug-ins for the Multimedia Framework. A
+sink is an object that can receive multimedia data; a source is an object
+that can supply it. This example implements a sink and a source as descriptor
+objects. </p> <p>Both the sink and source are implemented in a single class, <codeph>CMMFExDescriptor</codeph>,
+that derives from <codeph>CMMFClip</codeph>. <codeph>CMMFClip</codeph> represents
+a multimedia clip (i.e. not a stream or hardware device), which, in turn,
+derives from the ECom sink interface <codeph>MDataSink</codeph>, and the source
+interface <codeph>MDataSource</codeph>. </p> <p>Both the example source and
+sink are passed on creation a packaged <codeph>TMMFExDescriptorParams</codeph> object,
+which specifies the descriptor to read/write, and the thread to which the
+descriptor belongs. </p> <p>Note that the default audio controller only uses
+the default sink/sources, and returns "not supported" if you attempt to use
+other sink/sources with it. </p> </section>
