Specifies the pixel aspect ratio (PAR) for the source and destination rectangles.
Syntax
typedef struct _DXVAHD_STREAM_STATE_ASPECT_RATIO_DATA {
BOOL Enable;
DXVAHD_RATIONAL SourceAspectRatio;
DXVAHD_RATIONAL DestinationAspectRatio;
} DXVAHD_STREAM_STATE_ASPECT_RATIO_DATA;
Members
Enable
If TRUE, the SourceAspectRatio and DestinationAspectRatio members contain valid values. Otherwise, the pixel aspect ratios are unspecified.
SourceAspectRatio
A DXVAHD_RATIONAL structure that contains the source PAR. The default state value is 1:1 (square pixels).
DestinationAspectRatio
A DXVAHD_RATIONAL structure that contains the destination PAR. The default state value is 1:1 (square pixels).
Remarks
Pixel aspect ratios of the form 0/n and n/0 are not valid.
If the Enable member is FALSE, the device ignores the values of SourceAspectRatio and DestinationAspectRatio.
