MFP_EVENT_TYPE enumeration (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 It has been superseded by MediaPlayer and IMFMediaEngine.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.]

Defines event types for the IMFPMediaPlayerCallback interface.

Syntax

typedef enum MFP_EVENT_TYPE {
  MFP_EVENT_TYPE_PLAY = 0,
  MFP_EVENT_TYPE_PAUSE = 1,
  MFP_EVENT_TYPE_STOP = 2,
  MFP_EVENT_TYPE_POSITION_SET = 3,
  MFP_EVENT_TYPE_RATE_SET = 4,
  MFP_EVENT_TYPE_MEDIAITEM_CREATED = 5,
  MFP_EVENT_TYPE_MEDIAITEM_SET = 6,
  MFP_EVENT_TYPE_FRAME_STEP = 7,
  MFP_EVENT_TYPE_MEDIAITEM_CLEARED = 8,
  MFP_EVENT_TYPE_MF = 9,
  MFP_EVENT_TYPE_ERROR = 10,
  MFP_EVENT_TYPE_PLAYBACK_ENDED = 11,
  MFP_EVENT_TYPE_ACQUIRE_USER_CREDENTIAL = 12
} ;

Constants

Remarks

For each event type, the IMFPMediaPlayerCallback::OnMediaPlayerEvent callback receives a pointer to a data structure. The first part of the data structure is always an MFP_EVENT_HEADER structure. The following table lists the data structure for each event type.

In your implementation of OnMediaPlayerEvent, you must cast the pEventHeader parameter to the correct structure type. A set of macros is defined for this purpose. These macros check the value of the event type and return NULL if there is a mismatch; otherwise they return a pointer to the correct structure type.
