Constants
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_NONENo flags are set (indicates no support). |
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_GENERAL_SUPPORT_OKIndicates 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_AVAILABLEIndicates support for changing the rate control in the middle of the encoding session. |
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_RESOLUTION_RECONFIGURATION_AVAILABLEIndicates support for changing the resolution in the middle of the encoding session. |
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_RATE_CONTROL_VBV_SIZE_CONFIG_AVAILABLEWhen 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_AVAILABLEIndicates 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_ARRAYSWhen 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_AVAILABLEIndicates support for delta quantization parameter (QP) usage in rate control. |
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_SUBREGION_LAYOUT_RECONFIGURATION_AVAILABLEIndicates support for dynamic subregion layout changes during an encoding session. |
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_RATE_CONTROL_ADJUSTABLE_QP_RANGE_AVAILABLEIndicates support for adjustable QP range in rate control. |
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_RATE_CONTROL_INITIAL_QP_AVAILABLEIndicates support for adjustable initial QP in rate control. |
D3D12DDI_VIDEO_ENCODER_SUPPORT_FLAG_0080_2_RATE_CONTROL_MAX_FRAME_SIZE_AVAILABLEIndicates 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).
