MFP_MEDIAITEM_CREATED_EVENT structure (mfplay.h)
[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 It has been superseded by MediaPlayer and IMFMediaEngine.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.]
Event structure for the MFP_EVENT_TYPE_MEDIAITEM_CREATED event. This event is sent when the IMFPMediaPlayer::CreateMediaItemFromURL or IMFPMediaPlayer::CreateMediaItemFromObject method completes.
Syntax
typedef struct MFP_MEDIAITEM_CREATED_EVENT {
MFP_EVENT_HEADER header;
IMFPMediaItem *pMediaItem;
DWORD_PTR dwUserData;
} MFP_MEDIAITEM_CREATED_EVENT;
Members
header
MFP_EVENT_HEADER structure that contains data common to all IMFPMediaPlayer events.
pMediaItem
Pointer to the IMFPMediaItem interface of the new media item. If creating the media item failed, this member is NULL.
dwUserData
Application-defined user data for the media item. This value is specified when the application calls CreateMediaItemFromURL or CreateMediaItemFromObject.
Remarks
To get a pointer to this structure, cast the pEventHeader parameter of the IMFPMediaPlayerCallback::OnMediaPlayerEvent method. You can use the MFP_GET_MEDIAITEM_CREATED_EVENT macro for this purpose.
Media items are created asynchronously. If multiple items are created, the operations can complete in any order, not necessarily in the same order as the method calls. You can use the dwUserData member to identify the items, if you have simultaneous requests pending.
