cv::MediaFrame class represents an image/media frame obtained from an external source.

cv::MediaFrame represents image data as specified in cv::MediaFormat. cv::MediaFrame is designed to be a thin wrapper over some external memory of buffer; the class itself provides an uniform interface over such types of memory. cv::MediaFrame wraps data from a camera driver or from a media codec and provides an abstraction layer over this memory to G-API. MediaFrame defines a compact interface to access and manage the underlying data; the implementation is fully defined by the associated Adapter (which is usually user-defined).
