A post_configure virtual method is added to allow codec subclasses to adjust the initialized parameters after MFXVideoDECODE_DecodeHeader is called from the gstmsdkdec::gst_msdkdec_handle_frame function. This is useful if codecs want to adjust the output parameters based on the codec-specific decoding options that are present in the mfxInfoMFX structure after MFXVideoDECODE_DecodeHeader initializes them.
