When multiplane overlays are used, these requirements apply to allocations that are created within Microsoft DirectX apps.
DirectX 11 resource creation
When the CreateResource(D3D11) function is called:
- The D3D10_DDI_BIND_PRESENT and D3D10_DDI_RESOURCE_MISC_SHARED constant values are set in the BindFlags member of the D3D11DDIARG_CREATERESOURCE structure, indicating that the allocation can be scanned out.
- It's possible that other bit-field flags in Flags will also be set, such as:
- D3D10_DDI_BIND_SHADER_RESOURCE
- D3D10_DDI_BIND_RENDER_TARGET
- D3D11_DDI_BIND_UNORDERED_ACCESS
- D3D11_DDI_BIND_DECODER
- D3D11_1DDI_RESOURCE_MISC_RESTRICTED_CONTENT
- D3D11_1DDI_RESOURCE_MISC_RESTRICT_SHARED_RESOURCE_DRIVER
- When the DXGI_DDI_PRIMARY_DESC structure is passed in the CreateResource(D3D11) call:
- DXGI_DDI_PRIMARY_DESC has an appropriate value for the VidPnSourceId member.
- DXGI_DDI_PRIMARY_DESC.ModeDesc matches the current mode.
- For multiplane overlay resources, the driver must not set the DXGI_DDI_PRIMARY_DRIVER_FLAG_NO_SCANOUT flag value in the DriverFlags member of DXGI_DDI_PRIMARY_DESC.
DirectX 9 resource creation
When the CreateResource2 function is called:
- The Primary and SharedResource bit-field flags in the Flags member of the D3DDDIARG_CREATERESOURCE2 structure are set.
- It's possible that other bit-field flags in Flags will also be set, such as:
- RenderTarget
- Texture
- DecodeRenderTarget
- RestrictedContent
- RestrictSharedAccess
- The VidPnSourceId member of the D3DDDIARG_CREATERESOURCE2 structure is properly initialized.
- The RefreshRate member of the D3DDDIARG_CREATERESOURCE2 structure contains zero.
