Adds AV01 FOURCC to the list of allowed media files, in order to allow parsing the IVF Container holding AV1 content. At a later point dynamic resolution change can be supported - therefore the sequence header OBU and frame header OBU of AV1 file must be parsed, which can be done in future with the help of gst-lib gstav1parse. https://bugzilla.gnome.org/show_bug.cgi?id=796677
