I have a lot of audio files in ‘.ogg’ and ‘.oga’ containers. When I browse the audio files through the ‘Files’ module (not through the database), KODI shows the filename and duration of the MP3 files. However, OGG files are ignored by KODI and for OGA files, it shows the file size instead of the duration (as it does for MP3 files).
I’m using KODI 18.7
