IMFPMediaItem::GetObject method (mfplay.h)

Article
12/05/2018

[The feature associated with this page, MFPlay, is a legacy feature. It has been superseded by MediaPlayer and IMFMediaEngine. Those features have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use MediaPlayer and IMFMediaEngine instead of DirectShow, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]

Gets the object that was used to create the media item.

Syntax

HRESULT GetObject(
  [out] IUnknown **ppIUnknown
);

Parameters

[out] ppIUnknown

Receives a pointer to the object's IUnknown interface. The caller must release the interface.

Return value

The method returns an HRESULT. Possible values include, but are not limited to, those in the following table.

Return code	Description
S_OK	The method succeeded.
MF_E_NOTFOUND	The media item was created from a URL, not from an object.
