Specifies state parameters for blit operations when using Microsoft DirectX Video Acceleration High Definition (DXVA-HD).
To set a state parameter, call the IDXVAHD_VideoProcessor::SetVideoProcessBltState method. This method takes a DXVAHD_BLT_STATE value and a byte array as input. The byte array contains state data, the structure of which is defined by the DXVAHD_BLT_STATE value.
Syntax
typedef enum _DXVAHD_BLT_STATE {
DXVAHD_BLT_STATE_TARGET_RECT = 0,
DXVAHD_BLT_STATE_BACKGROUND_COLOR = 1,
DXVAHD_BLT_STATE_OUTPUT_COLOR_SPACE = 2,
DXVAHD_BLT_STATE_ALPHA_FILL = 3,
DXVAHD_BLT_STATE_CONSTRICTION = 4,
DXVAHD_BLT_STATE_PRIVATE = 1000
} DXVAHD_BLT_STATE;
Constants
DXVAHD_BLT_STATE_TARGET_RECTValue: 0 Specifies the target rectangle, which is the area within the destination surface where the output will be drawn. The state data is a DXVAHD_BLT_STATE_TARGET_RECT_DATA structure. |
DXVAHD_BLT_STATE_BACKGROUND_COLORValue: 1 Specifies the background color. The state data is a DXVAHD_BLT_STATE_BACKGROUND_COLOR_DATA structure. |
DXVAHD_BLT_STATE_OUTPUT_COLOR_SPACEValue: 2 Specifies the output color space. The state data is a DXVAHD_BLT_STATE_OUTPUT_COLOR_SPACE_DATA structure. |
DXVAHD_BLT_STATE_ALPHA_FILLValue: 3 Specifies how DXVA-HD device calculates output alpha values. The state data is a DXVAHD_BLT_STATE_ALPHA_FILL_DATA structure. |
DXVAHD_BLT_STATE_CONSTRICTIONValue: 4 Specifies the amount of downsampling to perform on the output. The state data is a DXVAHD_BLT_STATE_CONSTRICTION_DATA structure. |
DXVAHD_BLT_STATE_PRIVATEValue: 1000 Specifies that the state data contains a private DXVA-HD blit state. Use this state for proprietary or device-specific parameters. The state data is a DXVAHD_BLT_STATE_PRIVATE_DATA structure. |
