SACD ISO playback
I would like VLC to be able to play back ISO files of Super Audio CD format. https://en.wikipedia.org/wiki/Super_Audio_CD
Right now, people need to use sacd_extract https://github.com/setmind/sacd-ripper with its optional GUI https://github.com/setmind/SACDExtractGUI and then a converter such as this one https://www.dbpoweramp.com/codec-central-dsd-dff-dsf-sacd.htm to convert SACDs to FLAC to play them in VLC.
However, it would be nice to be able to skip all those steps and just play SACDs and their ISOs directly: particularly on Android. Kodi has an add-on for it https://kodi.wiki/view/Add-on:SACD_ISO_support but enabling that tends to mess up how Kodi handles DVD ISOs. So it's also important that this doesn't mess up VLC's existing functionality to play back DVD ISOs.
