Detailed Description

G-API streaming source based on OneVPL implementation.

This class implements IStreamSource interface. Its constructor takes source file path (in usual way) or onevpl::IDataProvider interface implementation (for not file-based sources). It also allows to pass-through oneVPL configuration parameters by using several onevpl::CfgParam.

Note: stream sources are passed to G-API via shared pointers, so please gapi::make_onevpl_src<> to create objects and ptr() to pass a GSource to cv::gin().
