Members

NodeIndex

[in] In a multi-adapter operation, NodeIndex indicates which physical adapter of the device that the operation applies to.

Codec

[in] A D3D12DDI_VIDEO_ENCODER_CODEC_0080 value that specifies the encode codec to use.

InputFormat

[in] A DXGI_FORMAT value that specifies the input format of the input frames.

CodecConfiguration

[in] A D3D12DDI_VIDEO_ENCODER_CODEC_CONFIGURATION_0082_0 structure that specifies the requested configuration for the selected codec. The codec-specific structure within this structure should match the codec type specified by Codec.

CodecGopSequence

[in] A D3D12DDI_VIDEO_ENCODER_SEQUENCE_GOP_STRUCTURE_0082_0 structure that specifies the requested group of pictures (GOP) configuration for the selected codec. The codec-specific structure within this structure should match the codec type specified by Codec.

RateControl

[in] A D3D12DDI_VIDEO_ENCODER_RATE_CONTROL_0080_2 structure that specifies the requested rate control configuration.

IntraRefresh

[in] A D3D12DDI_VIDEO_ENCODER_INTRA_REFRESH_MODE_0080 value that specifies the requested intra refresh mode.

SubregionFrameEncoding

[in] A D3D12DDI_VIDEO_ENCODER_FRAME_SUBREGION_LAYOUT_MODE_0080 value that specifies the requested subregion partitioning mode.

ResolutionsListCount

[in] Indicates the number of resolutions in the list that pResolutionList points to.

pResolutionList

[in] Pointer to an array of D3D12DDI_VIDEO_ENCODER_PICTURE_RESOLUTION_DESC_0080 structures that specifies the list of resolutions requested to be supported.

MaxDPBCapacity

[in] The maximum number of previous reference frames to be used when calling EncodeFrame for inter-frames. This value is used to calculate the suggested level.

ValidationFlags

[out] A D3D12DDI_VIDEO_ENCODER_VALIDATION_FLAGS_0082_0 value that provides more details if the cap query returns with theD3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0083_0_GENERAL_SUPPORT_OK bit not set.

SupportFlags

[out] A D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAGS_0082_0 value that specifies the support details for the requested configuration.

SuggestedProfile

[out] A D3D12DDI_VIDEO_ENCODER_PROFILE_DESC_0080_2 structure in which the driver returns the matching profile for the requested configuration.

SuggestedLevel

[out] A D3D12DDI_VIDEO_ENCODER_LEVEL_SETTING_0080_2 structure in which the driver returns the matching level for the requested configuration for each resolution present in pResolutionList.

pResolutionDependentSupport

[out] Pointer to a list of D3D12DDI_VIDEO_ENCODER_RESOLUTION_SUPPORT_LIMITS_0080_2 structures in which the driver returns the resolution-dependent support limits.

Remarks

Use D3D12DDICAPS_VIDEO_ENCODER_SUPPORT_DATA_0083_0 for full video encoding feature support for Windows 11 (WDDM 3.0).
