DXVAHDDDI_STREAM_STATE_OUTPUT_RATE_DATA structure (d3dumddi.h)
The DXVAHDDDI_STREAM_STATE_OUTPUT_RATE_DATA structure describes stream-state data that specifies the output rate of the input stream.
Syntax
typedef struct _DXVAHDDDI_STREAM_STATE_OUTPUT_RATE_DATA {
[in] BOOL RepeatFrame;
[in] DXVAHDDDI_OUTPUT_RATE OutputRate;
[in] DXVAHDDDI_RATIONAL CustomRate;
} DXVAHDDDI_STREAM_STATE_OUTPUT_RATE_DATA;
Members
[in] RepeatFrame
A Boolean value that specifies whether the frame rate conversion repeats or interpolates the frames. The driver refers to RepeatFrame only when it uses the frame rate conversion. The default value is FALSE, which indicates that the frame rate conversion interpolates the frames.
[in] OutputRate
A DXVAHDDDI_OUTPUT_RATE-typed value that indicates the output rate of the input stream. The default value is DXVAHDDDI_OUTPUT_RATE_NORMAL.
[in] CustomRate
A DXVAHDDDI_RATIONAL structure that specifies a fractional value that represents a custom output rate. The driver refers to CustomRate only when the value that is specified in OutputRate is DXVAHDDDI_OUTPUT_RATE_CUSTOM. The default value is 1/1.
Remarks
The driver uses the RepeatFrame member to control the frame rate conversion. For example, when the driver converts from 60i to 60p, if the video processor is capable of both the inverse telecine (60i to 24p) and the frame rate conversion (24p to 60p), then the converted frames contains interpolated frames. Sometimes the interpolation results in artifacts, and the application might require to repeat the frames instead.
The CustomRate member must specify one of the custom rates that the driver supplied in the members of the DXVAHDDDI_CUSTOM_RATE_DATA structure when the driver's GetCaps function was called with the D3DDDICAPS_DXVAHD_GETVPCUSTOMRATES value set; otherwise, the driver's SetVideoProcessStreamState function returns an error.
