/**
|
|
* @brief G-API streaming source based on OneVPL implementation.
|
|
*
|
|
* This class implements IStreamSource interface.
|
|
* Its constructor takes source file path (in usual way) or @ref onevpl::IDataProvider
|
|
* interface implementation (for not file-based sources). It also allows to pass-through
|
|
* oneVPL configuration parameters by using several @ref 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().
