DXVAHD_STREAM_STATE_OUTPUT_RATE_DATA structure (dxvahd.h)
Specifies the output frame rate for an input stream when using Microsoft DirectX Video Acceleration High Definition (DXVA-HD).
Syntax
typedef struct _DXVAHD_STREAM_STATE_OUTPUT_RATE_DATA {
BOOL RepeatFrame;
DXVAHD_OUTPUT_RATE OutputRate;
DXVAHD_RATIONAL CustomRate;
} DXVAHD_STREAM_STATE_OUTPUT_RATE_DATA;
Members
RepeatFrame
Specifies how the device performs frame-rate conversion, if required. The default state value is FALSE (interpolation).
| Value | Meaning |
|---|---|
|
The device repeats frames. |
|
The device interpolates frames. |
OutputRate
Specifies the output rate, as a member of the DXVAHD_OUTPUT_RATE enumeration.
CustomRate
Specifies a custom output rate, as a DXVAHD_RATIONAL structure. This member is ignored unless OutputRate equals DXVAHD_OUTPUT_RATE_CUSTOM. The default state value is 1/1.
To get the list of custom rates supported by the video processor, call IDXVAHD_Device::GetVideoProcessorCustomRates. If a custom rate is used, it must be taken from this list.
Remarks
The output rate might require the device to convert the frame rate of the input stream. If so, the value of RepeatFrame controls whether the device creates interpolated frames or simply repeats input frames.
