DXVAHD_STREAM_STATE enumeration (dxvahd.h)

  • Article

Specifies state parameters for an input stream to a Microsoft DirectX Video Acceleration High Definition (DXVA-HD) video processor.

To set a state parameter, call IDXVAHD_VideoProcessor::SetVideoProcessStreamState. This method takes a DXVAHD_STREAM_STATE value and a byte array as input. The byte array contains state data, the structure of which is defined by the DXVAHD_STREAM_STATE value.

Constants

 
DXVAHD_STREAM_STATE_D3DFORMAT
Value: 0
Specifies the video format of the input stream. The state data is a DXVAHD_STREAM_STATE_D3DFORMAT_DATA structure.
DXVAHD_STREAM_STATE_FRAME_FORMAT
Value: 1
Specifies how the input stream is interlaced. The state data is a DXVAHD_STREAM_STATE_FRAME_FORMAT_DATA structure.
DXVAHD_STREAM_STATE_INPUT_COLOR_SPACE
Value: 2
Specifies the color space for the input stream. The state data is a DXVAHD_STREAM_STATE_INPUT_COLOR_SPACE_DATA structure.
DXVAHD_STREAM_STATE_OUTPUT_RATE
Value: 3
Specifies the output frame rate. The state data is a DXVAHD_STREAM_STATE_OUTPUT_RATE_DATA structure.
DXVAHD_STREAM_STATE_SOURCE_RECT
Value: 4
Specifies the source rectangle. The source rectangle defines which portion of the input sample is blitted to the destination surface. The state data is a DXVAHD_STREAM_STATE_SOURCE_RECT_DATA structure.
DXVAHD_STREAM_STATE_DESTINATION_RECT
Value: 5
Specifies the destination rectangle. The destination rectangle defines which portion of the destination rectangle receives the blit. The state data is a DXVAHD_STREAM_STATE_DESTINATION_RECT_DATA structure.
DXVAHD_STREAM_STATE_ALPHA
Value: 6
Specifies the planar alpha value for this input stream. The state data is a DXVAHD_STREAM_STATE_ALPHA_DATA structure.
DXVAHD_STREAM_STATE_PALETTE
Value: 7
Specifies the color-palette entries. The state data is a DXVAHD_STREAM_STATE_PALETTE_DATA structure.

This setting is used for palettized input formats, such as AI44 and IA44.
DXVAHD_STREAM_STATE_LUMA_KEY
Value: 8
Specifies the luma key. The state data is a DXVAHD_STREAM_STATE_LUMA_KEY_DATA structure.

This state is applicable only if the device supports luma keying. To find out if the device supports luma keying, check for the DXVAHD_FEATURE_CAPS_LUMA_KEY flag in the FeatureCaps member of the DXVAHD_VPDEVCAPS capabilities structure.
DXVAHD_STREAM_STATE_ASPECT_RATIO
Value: 9
Specifies the pixel aspect ratio of the source and destination surfaces. The state data is a DXVAHD_STREAM_STATE_ASPECT_RATIO_DATA structure.
DXVAHD_STREAM_STATE_FILTER_BRIGHTNESS
Value: 100
Specifies the brightness filter. The state data is a DXVAHD_STREAM_STATE_FILTER_DATA structure.
DXVAHD_STREAM_STATE_FILTER_CONTRAST
Value: 101
Specifies the contrast filter. The state data is a DXVAHD_STREAM_STATE_FILTER_DATA structure.
DXVAHD_STREAM_STATE_FILTER_HUE
Value: 102
Specifies the hue filter. The state data is a DXVAHD_STREAM_STATE_FILTER_DATA structure.
DXVAHD_STREAM_STATE_FILTER_SATURATION
Value: 103
Specifies the saturation filter. The state data is a DXVAHD_STREAM_STATE_FILTER_DATA structure.
DXVAHD_STREAM_STATE_FILTER_NOISE_REDUCTION
Value: 104
Specifies the noise-reduction filter. The state data is a DXVAHD_STREAM_STATE_FILTER_DATA structure.
DXVAHD_STREAM_STATE_FILTER_EDGE_ENHANCEMENT
Value: 105
Specifies the edge-enhancement filter. The state data is a DXVAHD_STREAM_STATE_FILTER_DATA structure.
DXVAHD_STREAM_STATE_FILTER_ANAMORPHIC_SCALING
Value: 106
Specifies the anamorphic-scaling value. The state data is a DXVAHD_STREAM_STATE_FILTER_DATA structure.
DXVAHD_STREAM_STATE_PRIVATE
Value: 1000
Specifies that the state data contains a private DXVA-HD stream state. The state data is a DXVAHD_STREAM_STATE_PRIVATE_DATA structure.

Use this state for proprietary or device-specific parameters.
