Detailed Documentation¶

Represents a blob that contains two planes (Y and UV) in NV12 color format.

Typedefs¶

typedef std::shared_ptr<NV12Blob> Ptr

A smart pointer to the NV12Blob object.

typedef std::shared_ptr<const NV12Blob> CPtr

A smart pointer to the const NV12Blob object.

Construction¶

NV12Blob(const Blob::Ptr& y, const Blob::Ptr& uv)

Constructs NV12 blob from two planes Y and UV.

Parameters:

y	Blob object that represents Y plane in NV12 color format
uv	Blob object that represents UV plane in NV12 color format

NV12Blob(Blob::Ptr&& y, Blob::Ptr&& uv)

Constructs NV12 blob from two planes Y and UV.

Parameters:

y	Blob object that represents Y plane in NV12 color format
uv	Blob object that represents UV plane in NV12 color format

Methods¶

virtual Blob::Ptr& y()

Returns a shared pointer to Y plane.

Returns:

Y plane

virtual const Blob::Ptr& y() const

Returns a shared pointer to Y plane.

Returns:

Y plane

virtual Blob::Ptr& uv()

Returns a shared pointer to UV plane.

Returns:

UV plane

virtual const Blob::Ptr& uv() const

Returns a shared pointer to UV plane.

Returns:

UV plane

virtual Blob::Ptr createROI(const ROI& roi) const

Creates a blob describing given ROI object based on the current blob with memory sharing.

Note: default implementation throws “not implemented” exception.

Parameters:

roi	A ROI object inside of the current blob.

Returns:

A shared pointer to the newly created ROI blob.
