Data Structures
class	InferenceEngine::gpu::D3DContext
	This class represents an abstraction for GPU plugin remote context which is shared with Direct3D 11 device. The plugin object derived from this class can be obtained either with GetContext() method of Executable network or using CreateContext() Core call. More...

class	InferenceEngine::gpu::D3DBufferBlob
	This class represents an abstraction for GPU plugin remote blob which is shared with Direct3D 11 buffer. The plugin object derived from this class can be obtained with CreateBlob() call. More...

class	InferenceEngine::gpu::D3DSurface2DBlob
	This class represents an abstraction for GPU plugin remote blob which is shared with Direct3D 11 2D texture. The plugin object derived from this class can be obtained with CreateBlob() call. More...

Functions
static Blob::Ptr	InferenceEngine::gpu::make_shared_blob_nv12 (size_t height, size_t width, RemoteContext::Ptr ctx, ID3D11Texture2D *nv12_surf)
	This function is used to obtain a NV12 compound blob object from NV12 DXGI video decoder output. The resulting compound contains two remote blobs for Y and UV planes of the surface.

static D3DContext::Ptr	InferenceEngine::gpu::make_shared_context (Core &core, std::string deviceName, ID3D11Device *device)
	This function is used to obtain remote context object from ID3D11Device.

static Blob::Ptr	InferenceEngine::gpu::make_shared_blob (const TensorDesc &desc, RemoteContext::Ptr ctx, ID3D11Buffer *buffer)
	This function is used to obtain remote blob object from ID3D11Buffer.

static Blob::Ptr	InferenceEngine::gpu::make_shared_blob (const TensorDesc &desc, RemoteContext::Ptr ctx, ID3D11Texture2D *surface, uint32_t plane=0)
	This function is used to obtain remote blob object from ID3D11Texture2D. More...

§ make_shared_blob()

static Blob::Ptr InferenceEngine::gpu::make_shared_blob	(	const TensorDesc &	desc,
		RemoteContext::Ptr	ctx,
		ID3D11Texture2D *	surface,
		uint32_t	plane = `0`
	)

inlinestatic

This function is used to obtain remote blob object from ID3D11Texture2D.

Parameters

desc	Tensor description
ctx	the RemoteContext object whuch owns context for the blob to be created
surface	Pointer to ID3D11Texture2D interface of the objects that owns NV12 texture
plane	ID of the plane to be shared (0 or 1)

Returns: Smart pointer to created RemoteBlob object cast to base class

Note: The underlying ID3D11Texture2D can also be a plane of output surface of DXGI video decoder
