Public class is using for creation of onevpl::GSource instances.
Class members available through methods CfgParam::get_name() and CfgParam::get_value() are used by onevpl::GSource inner logic to create or find oneVPL particular implementation (software/hardware, specific API version and etc.).

parameters. This kind of CfgParams are created using is_major = false
argument in CfgParam::create method and are not used by creating oneVPL particular implementations. Instead they fill out a "score table" to select preferable implementation from available list. Implementation are satisfying with most of these optional params would be chosen. If no one optional CfgParam params were present then first of available oneVPL implementation would be applied. Please get on https://spec.oneapi.io/versions/latest/elements/oneVPL/source/API_ref/VPL_disp_api_func.html?highlight=mfxcreateconfig#mfxsetconfigfilterproperty for using OneVPL configuration.

Special configuration parameter names for onevp::GSource:
If not set then MFX implementation will use default acceleration behavior: all decoding operation uses default GPU resources but MediaFrame produces data allocated by using host RAM
