                            As a reference to compare the SVT-AV1

                            librav1e<br>
                            with simple or none (default) parameters.
                            Other, optimal tuned parameters may possibly
                            change the unsuccesful results here.<br>
                            Seemingly something have to be wrong here,

                            The CPU (i7 quad-cores 8 threads)
