deviceName	A name of to create a remote context for
device	A pointer to ID3D11Device to be used to create a remote context
target_tile_id	Desired tile id within given context for multi-tile system. Default value (-1) means that root device should be used

Returns:

A shared remote context instance

static INFERENCE_ENGINE_1_0_DEPRECATED Blob::Ptrconst TensorDesc&RemoteContext::PtrID3D11Buffer \* make_shared_blob(
    ,
    ,

    )

This function is used to obtain remote blob object from ID3D11Buffer.

Parameters:

desc	A tensor description which describes blob configuration
ctx	A shared pointer to a remote context
buffer	A pointer to ID3D11Buffer instance to create remote blob based on

Returns:

A remote blob instance

static INFERENCE_ENGINE_1_0_DEPRECATED Blob::Ptrconst TensorDesc&RemoteContext::PtrID3D11Texture2D \*uint32_t make_shared_blob(
    ,
    ,
    ,

    )

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

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

Parameters:

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

static INFERENCE_ENGINE_1_0_DEPRECATED RemoteContext::PtrCore&std::stringcl_contextint make_shared_context(
    ,
    ,
    ,

    )

This function is used to obtain remote context object from user-supplied OpenCL context handle.

Parameters:

core	A reference to Inference Engine Core object
deviceName	A name of device to create a remote context for
ctx	A OpenCL context to be used to create shared remote context
target_tile_id	Desired tile id within given context for multi-tile system. Default value (-1) means that root device should be used

Returns:

A shared remote context instance

static INFERENCE_ENGINE_1_0_DEPRECATED RemoteContext::PtrCore&std::stringcl_command_queue make_shared_context(
