MFP_FRAME_STEP_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 It has been superseded by MediaPlayer and IMFMediaEngine.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_FRAME_STEP event. This event is sent when the IMFPMediaPlayer::FrameStep method completes.
Syntax
typedef struct MFP_FRAME_STEP_EVENT {
MFP_EVENT_HEADER header;
IMFPMediaItem *pMediaItem;
} MFP_FRAME_STEP_EVENT;
Members
header
MFP_EVENT_HEADER structure that contains data common to all IMFPMediaPlayer events.
pMediaItem
Pointer to the IMFPMediaItem interface of the current media item.
Remarks
To get a pointer to this structure, cast the pEventHeader parameter of the IMFPMediaPlayerCallback::OnMediaPlayerEvent method. You can use the MFP_GET_FRAME_STEP_EVENT macro for this purpose.
