#11663: lv2 omitted values printed as NaN in help -------------------------------------+------------------------------------- Reporter: Dave Flater | Type: defect Status: new | Priority: normal Component: avfilter | Version: git- | master Keywords: LV2 | Blocked By: Blocking: | Reproduced by developer: 0 Analyzed by developer: 0 | -------------------------------------+------------------------------------- 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. -- Ticket URL: <https://trac.ffmpeg.org/ticket/11663> FFmpeg <https://ffmpeg.org> FFmpeg issue tracker
