Detailed Description

An interface class for MediaFrame data adapters.

Implement this interface to wrap media data in the MediaFrame. It makes sense to implement this class if there is a custom cv::gapi::wip::IStreamSource defined – in this case, a stream source can produce MediaFrame objects with this adapter and the media data may be passed to graph without any copy. For example, a GStreamer-based stream source can implement an adapter over GstBuffer and G-API will transparently use it in the graph.
