Audio Files and MIME Types

To play all audio formats supported by Audio Player, it can be necessary to add unknown formats to ownCloud/Nextcloud. The formats .m4a and .m4b were added in ownCloud/Nextcloud 9.1.0.

Add Custom MIME Types

By default ownCloud/Nextcloud is distributed with resources/config/mimetypemapping.dist.json. Do not modify this file, as it will be replaced when ownCloud/Nextcloud is updated. Instead, create your own config/mimetypemapping.json file and add your own MIME types.

After that you have to update the table *PREFIX*mimetypes with the newly added MIME types and correct the file mappings in the table *PREFIX*filecache with occ command ./occ maintenance:mimetype:update-db --repair-filecache as well as the core/js/mimetypelist.js with command ./occ maintenance:mimetype:update-js.
