Low-level API for external libraries / plugins#

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.
