AMOVERLAYFX enumeration (strmif.h)

  • Article

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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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

Specifies effects on a DirectDraw hardware overlay surface.

Syntax

typedef enum AMOVERLAYFX {
  AMOVERFX_NOFX = 0,
  AMOVERFX_MIRRORLEFTRIGHT = 0x2,
  AMOVERFX_MIRRORUPDOWN = 0x4,
  AMOVERFX_DEINTERLACE = 0x8
} ;

Constants

 
AMOVERFX_NOFX

AMOVERFX_MIRRORUPDOWN

When used in IAMOverlayFX::QueryOverlayFXCaps, this flag specifies whether the hardware can support the DirectDraw 7 DDOVERFX_DEINTERLACE hint. When used with the IAMOverlayFX::GetOverlayFX or IAMOverlayFX::SetOverlayFX methods, this flag indicates that the overlay should be deinterlaced if possible.
