IWMMediaProps::SetMediaType method (wmsdkidl.h)
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The SetMediaType method specifies the media type.
Syntax
HRESULT SetMediaType(
[in] WM_MEDIA_TYPE *pType
);
Parameters
[in] pType
Pointer to the WM_MEDIA_TYPE structure describing the input, stream, or output.
Return value
The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.
| Return code | Description |
|---|---|
|
The method succeeded. |
|
The pType parameter is NULL, cbFormat is 0 or too large, or pbFormat is NULL. |
|

Remarks
It is possible to successfully set a media type in this method that will ultimately be rejected as invalid when the profile is set on the writer. For a list of tests that the writer performs on the profile, see IWMWriter::SetProfile.
