Description
lilv.h says about the function lilv_plugin_get_port_ranges_float, "If a port doesn't have a minimum, maximum or default value... the corresponding array element will be set to NaN."
When the help option is used to print available controls and their valid ranges, libavfilter/af_lv2.c should omit the fields that contain NaNs, like lv2info does, rather than outputting the NaNs. When a minimum or maximum is shown as NaN, it misleadingly suggests that a cursed numerical comparison with NaN might happen in a range check.
