MmfExFormatPlugin demonstrates
how to implement format encoder and decoder plug-ins for the Multimedia Framework.
Multimedia data is usually packaged in a particular format, which specify
the properties of the data (e.g. duration, frame intervals), and how the buffers
for holding the data are organised. A format decoder plug-in is responsible
for reading a particular format; a format encoder plug-in for writing a particular
format.
The example handles the RAW audio format (PCM data with no
headers). The decoder plug-in CMMFRawFormatRead reads RAW
audio; it implements the ECom interface CMMFFormatDecode.
The encoder plug-in CMMFRawFormatWrite writes RAW audio:
it implements the ECom interface CMMFFormatEncode.
