MFP_ERROR_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 It has been superseded by MediaPlayer and IMFMediaEngine.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_ERROR event. This event is sent if an error occurs during playback.

Syntax

typedef struct MFP_ERROR_EVENT {
  MFP_EVENT_HEADER header;
} MFP_ERROR_EVENT;

Members

header

MFP_EVENT_HEADER structure that contains data common to all IMFPMediaPlayer events. The hrEvent member of the structure contains the error code.

Remarks

To get a pointer to this structure, cast the pEventHeader parameter of the IMFPMediaPlayerCallback::OnMediaPlayerEvent method. You can use the MFP_GET_ERROR_EVENT macro for this purpose.

This event is not used to signal the failure of an asynchronous IMFPMediaPlayer method. If an asynchronous method fails, the error is reported in the standard event listed for that method. The MFP_EVENT_TYPE_ERROR event is used for errors that happen outside the context of an asynchronous method call.
