The IWMReaderAccelerator interface is implemented on the reader object only when it is in decoding mode. It is called by a player or a player source filter to obtain interfaces from the decoder DMO.
The IWMReaderAccelerator interface has these methods.
|IWMReaderAccelerator::GetCodecInterface||The GetCodecInterface method is used to retrieve a pointer to the IWMCodecAMVideoAccelerator interface exposed on the decoder DMO.|
|IWMReaderAccelerator::Notify||The Notify method is called by the source filter to pass in the negotiated media type.|
