Low-level API for external libraries / plugins

Classes
struct	OpenCV_API_Header

Enumerations
enum	CvResult {   CV_ERROR_FAIL = -1 ,   CV_ERROR_OK = 0 }

Detailed Description

API for OpenCV external plugins:

• HAL accelerators
• VideoIO camera backends / decoders / encoders
• Imgcodecs encoders / decoders

Plugins are usually built separately or before OpenCV (OpenCV can depend on them - like HAL libraries).

Using this approach OpenCV provides some basic low level functionality for external plugins.
