VUI(Video Usability Information) parameters should be set according to the specification. However, some of the existing hardware decoders refuse to decode in certain combinations of the resolution and VUI parameters. To support the legacy decoders, this patch provides 'insert-vui' to skip the settings. https://bugzilla.gnome.org/show_bug.cgi?id=791331
