Constants

 
D3D12_VIDEO_PROCESS_FEATURE_FLAG_NONE
No features are supported.
D3D12_VIDEO_PROCESS_FEATURE_FLAG_ALPHA_FILL
The video processor can set alpha values on the output pixels. The alpha fill mode is used in D3D12_VIDEO_PROCESS_OUTPUT_STREAM_DESC. D3D12_VIDEO_PROCESS_ALPHA_FILL_MODE_OPAQUE must be always supported. The background, destination, and source stream modes are only supported when the driver reports D3D12_VIDEO_PROCESS_FEATURE_FLAG_ALPHA_FILL.
D3D12_VIDEO_PROCESS_FEATURE_FLAG_LUMA_KEY
The video processor can perform luma keying. Luma keying is configured via the D3D12_VIDEO_PROCESS_LUMA_KEY member of the D3D12_VIDEO_PROCESS_INPUT_STREAM_ARGUMENTS structure. For more information see <a href=ns-d3d12video-d3d12_video_process_luma_key"">D3D12_VIDEO_PROCESS_LUMA_KEY.
D3D12_VIDEO_PROCESS_FEATURE_FLAG_STEREO
The video processor can support 3D stereo video. For more information, see D3D12_VIDEO_FRAME_STEREO_FORMAT.

All drivers setting this capability must support the following stereo formats: D3D12_VIDEO_PROCESS_STEREO_FORMAT_HORIZONTAL, D3D12_VIDEO_PROCESS_STEREO_FORMAT_VERTICAL, and D3D12_VIDEO_PROCESS_STEREO_FORMAT_SEPARATE.
D3D12_VIDEO_PROCESS_FEATURE_FLAG_ROTATION
The driver can rotate the input data either 90, 180, or 270 degrees clockwise as part of the video processing operation.
D3D12_VIDEO_PROCESS_FEATURE_FLAG_FLIP
The driver can flip the input data horizontally or vertically, together or separately with a video rotation operation.
D3D12_VIDEO_PROCESS_FEATURE_FLAG_ALPHA_BLENDING
Alpha blending and a planar alpha may be set in the AlphaBlending member of the D3D12_VIDEO_PROCESS_INPUT_STREAM_ARGUMENTS structure. For more information see D3D12_VIDEO_PROCESS_ALPHA_BLENDING.
D3D12_VIDEO_PROCESS_FEATURE_FLAG_PIXEL_ASPECT_RATIO
The driver supports changing the pixel aspect ratio. If the driver does not report this capability, then the SourceAspectRatio and DestinationAspectRatio members of D3D12_VIDEO_PROCESS_INPUT_STREAM_ARGUMENTS structure must indicate a 1:1 aspect ratio.
