Detailed Documentation

This class represents an abstraction for GPU plugin remote tensor which is shared with VA output surface. The plugin object derived from this class can be obtained with VAContext::create_tensor() call.

User can also obtain OpenCL 2D image handle from this class.

Methods

static void type_check(const Tensor& tensor)

Checks that type defined runtime parameters are presented in remote object.

Parameters:

tensor

a tensor to check

operator VASurfaceID ()

VASurfaceID conversion operator for the VASurfaceTensor object.

Returns:

VASurfaceID handle

uint32_t plane()

Returns plane ID of underlying video decoder surface.

Returns:

Plane ID
