Constants

 
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_NONE
No flags are set (indicates no support).
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_GENERAL_SUPPORT_OK
Indicates whether the given configuration is generally supported by the encoder, in combination with the remaining flags to convey certain limitations or no general support. The D3D12 Debug layer can provide further information.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_RATE_CONTROL_RECONFIGURATION_AVAILABLE
Indicates support for changing the rate control in the middle of the encoding session.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_RESOLUTION_RECONFIGURATION_AVAILABLE
Indicates support for changing the resolution in the middle of the encoding session.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_RATE_CONTROL_VBV_SIZE_CONFIG_AVAILABLE
When set, enables configuring the video buffering verifier (VBV) initial fullness and capacity for rate control algorithms.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_RATE_CONTROL_FRAME_ANALYSIS_AVAILABLE
Indicates support for rate control modes that involve frame analysis to optimize the bitrate usage at the cost of slower performance.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_RECONSTRUCTED_FRAMES_REQUIRE_CONTIGUOUS_TEXTURE_ARRAYS
When set, textures that refer reconstructed pictures can only be referenced as a texture array, as opposed to an array of separate texture 2D resources with each resource having array size of 1.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_RATE_CONTROL_DELTA_QP_AVAILABLE
Indicates support for delta quantization parameter (QP) usage in rate control.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_SUBREGION_LAYOUT_RECONFIGURATION_AVAILABLE
Indicates support for dynamic subregion layout changes during an encoding session.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_RATE_CONTROL_ADJUSTABLE_QP_RANGE_AVAILABLE
Indicates support for adjustable QP range in rate control.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_RATE_CONTROL_INITIAL_QP_AVAILABLE
Indicates support for adjustable initial QP in rate control.
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_RATE_CONTROL_MAX_FRAME_SIZE_AVAILABLE
Indicates support for setting a maximum cap in the bitrate algorithm per each encoded frame.

Remarks

Use D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAGS_0083_0 for full video encoding feature support for Windows 11 (WDDM 3.0).
