MF_MT_AM_FORMAT_TYPE attribute
Contains a DirectShow format GUID for a media type.
Data type
GUID
Remarks
This attribute might be set when a DirectShow media type is converted into a Media Foundation media type. The attribute indicates the original DirectShow format type. The value corresponds to the formattype member of the AM_MEDIA_TYPE structure.
For an audio format, the MF_MT_USER_DATA attribute might contain the original format block, if the DirectShow format type was not recognized.
Do not set this attribute on a media type unless you are converting a DirectShow format structure.
The GUID constant for this attribute is exported from mfuuid.lib.
