+<concept id="GUID-8D8202BB-1070-5EE2-85C0-E37AABA67340" xml:lang="en"><title>MmfExCodec:
+Multimedia Framework codec plug-in example</title><prolog><metadata><keywords/></metadata></prolog><conbody>
+<section><title>Description</title> <p> <filepath>MmfExCodec</filepath> demonstrates
+how to implement a codec plug-in for the Multimedia Framework. A codec converts
+media data in one encoding into another encoding. The example converts audio
+data encoded with PCM8 into PCM16. </p> <p>The program is an ECom plug-in
+that implements the codec interface <codeph>CMMFCodec</codeph> by the class <codeph>CMMFExPcm8Pcm16Codec</codeph>.
+When a client or media format requires a PCM8 to PCM16 codec, the Multimedia
+Framework will instantiate a <codeph>CMMFExPcm8Pcm16Codec</codeph> object,
+and call its <codeph>ProcessL()</codeph> member function to convert data supplied
+a source buffer. As converting PCM8 into PCM16 only requires expanding each
+byte in the source buffer into two bytes in the destination buffer, <codeph>CMMFExPcm8Pcm16Codec::ProcessL()</codeph> is
+not very complex. </p> </section>
