Remarks
Use the IMFAttributes pointer retrieved by this method to get or set attributes that apply to the entire MFT. To get the attribute store for an input stream, call IMFTransform::GetInputStreamAttributes. To get the attribute store for an output stream, call IMFTransform::GetOutputStreamAttributes.
Implementation of this method is optional unless the MFT needs to support a particular set of attributes. Exception: Hardware-based MFTs must implement this method. See Hardware MFTs.
