Windows Driver Kit DDI reference (ns-d3d12umddi-d3d12ddicaps_video_encoder_output_resolution_ratios_count_data_0080_2)

Description

The D3D12DDICAPS_VIDEO_ENCODER_OUTPUT_RESOLUTION_RATIOS_COUNT_DATA_0080_2 structure is used to retrieve the number of supported resolution ratios based on the specified codec, profile, and level.

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 codec to check support for.

`ResolutionRatiosCount`

[out] The number of resolution ratios supported for this configuration.

Remarks

The D3D runtime calls PFND3D12DDI_VIDEO_GETCAPS with D3D12DDICAPS_TYPE_VIDEO_0080_ENCODER_OUTPUT_RESOLUTION_RATIOS_COUNT specified as the capability type.

See D3D12 video encoding for general information.
