DXVA2_SampleFormat enumeration (dxva2api.h)

  • Article

Describes the content of a video sample. These flags are used in the DXVA2_ExtendedFormat structure.

Syntax

typedef enum _DXVA2_SampleFormat {
  DXVA2_SampleFormatMask = 0xff,
  DXVA2_SampleUnknown = 0,
  DXVA2_SampleProgressiveFrame = 2,
  DXVA2_SampleFieldInterleavedEvenFirst = 3,
  DXVA2_SampleFieldInterleavedOddFirst = 4,
  DXVA2_SampleFieldSingleEven = 5,
  DXVA2_SampleFieldSingleOdd = 6,
  DXVA2_SampleSubStream = 7
} DXVA2_SampleFormat;

Constants

 
DXVA2_SampleFormatMask
Value: 0xff
Bitmask to validate flag values. This value is not a valid flag.
DXVA2_SampleUnknown
Value: 0
Unknown format. Default to DXVA2_SampleProgressiveFrame.
DXVA2_SampleProgressiveFrame
Value: 2
The sample contains a progressive (non-interlaced) frame.
DXVA2_SampleFieldInterleavedEvenFirst
Value: 3
The sample contains two interleaved fields. The even field should be displayed first.
DXVA2_SampleFieldInterleavedOddFirst
Value: 4
The sample contains two interleaved fields. The odd field should be displayed first.
DXVA2_SampleFieldSingleEven
Value: 5
The sample contains a single even field.
DXVA2_SampleFieldSingleOdd
Value: 6
The sample contains a single odd field.
DXVA2_SampleSubStream
Value: 7
The sample contains a video substream frame. Use this value for substream mixing.

Remarks

This enumeration is equivalent to the DXVA_SampleFormat enumeration used in DXVA 1.0.

The following table shows the mapping from MFVideoInterlaceMode enumeration values, which are used in Media Foundation media types, to DXVA2_SampleFormat values.

MFVideoInterlaceMode Value DXVA2_SampleFormat Value
MFVideoInterlace_Unknown DXVA2_SampleUnknown.
MFVideoInterlace_Progressive DXVA2_SampleProgressiveFrame.
MFVideoInterlace_FieldInterleavedUpperFirst DXVA2_SampleFieldInterleavedEvenFirst
MFVideoInterlace_FieldInterleavedLowerFirst DXVA2_SampleFieldInterleavedOddFirst.
MFVideoInterlace_FieldSingleUpper DXVA2_SampleFieldSingleEven.
MFVideoInterlace_FieldSingleLower DXVA2_SampleFieldSingleOdd.
MFVideoInterlace_MixedInterlaceOrProgressive No exact match. Use DXVA2_SampleFieldInterleavedEvenFirst as an initial value, then use the interlace flags from the media samples. For more information, see Video Interlacing.
 

With the exception of MFVideoInterlace_MixedInterlaceOrProgressive, each pair of corresponding enumeration values has the same numeric value.

The value DXVA2_SampleSubStream has no equivalent in the MFVideoInterlaceMode enumeration.
