In X264_BUILD >= 78, b-pyramid became a non-boolean so passing a boolean argument to the option string value causes an error. For < 78 we pass the boolean value, for >= 78 we use the x264_b_pyramid_names[] array which will result in passing 'none' for false and 'strict' for true. Other modes can be set through the option-string property for now. https://bugzilla.gnome.org/show_bug.cgi?id=626577
