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.
