_DVRESOLUTION 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 It has been superseded by MediaPlayer, IMFMediaEngine, and Audio/Video Capture in Media Foundation.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.]

Indicates the digital video (DV) decoding resolution.

Syntax

typedef enum _DVRESOLUTION {
  DVRESOLUTION_FULL = 1000,
  DVRESOLUTION_HALF = 1001,
  DVRESOLUTION_QUARTER = 1002,
  DVRESOLUTION_DC = 1003
} ;

Constants

 
DVRESOLUTION_FULL
Value: 1000
Decode at full size.
DVRESOLUTION_HALF
Value: 1001
Decode at half size.
DVRESOLUTION_QUARTER
Value: 1002
Decode at quarter size.
DVRESOLUTION_DC
Value: 1003
Decode at one-eighth size.

Remarks

The decoding resolution depends on whether the current format is NTSC or PAL:

Enumeration NTSC PAL
DVRESOLUTION_FULL 720 x 480 720 x 576
DVRESOLUTION_HALF 360 x 240 360 x 288
DVRESOLUTION_QUARTER 180 x 120 180 x 144
DVRESOLUTION_DC 88 x 60 88 x 72
 

The following enumeration defined in strmif.h is equivalent to the _DVRESOLUTION enumeration. It is included for compatibility with existing applications.

enum _DVDECODERRESOLUTION {
    DVDECODERRESOLUTION_720x480     =   1000,
    DVDECODERRESOLUTION_360x240     =   1001,
    DVDECODERRESOLUTION_180x120     =   1002,
    DVDECODERRESOLUTION_88x60       =   1003
};
