Previews for Office files using LibreOffice
-------------------------------------------

Nextcloud can generate previews for Office files using LibreOffice.

Since Nextcloud 28, you can also create previews for EMF files.

To enable it, add ``'OC\Preview\EMF'`` to ``enabledPreviewProviders``.


Until Nextcloud 28, the same LibreOffice user profile was used to generate the previews. LibreOffice can only be invoked once per user profile, so the generation of a preview for an office file would fail if another one were created right now.

Beginning with Nextcloud 28, a different LibreOffice user profile is used for each file. Downside: If you upload 100 emf files, you may end up with 100 LibreOffice
invocations. Though, you can use ``preview_concurrency_new`` and ``preview_concurrency_all`` to limit the number of previews that can be generated concurrently when php-sysvsem is available.

* The recommended :ref:`nginx configuration<nginx-config>` changed as Nextcloud Talk now serves audio files with ``.ogg`` / ``.flac`` extension, make sure to add these extensions to the list of static files.
The configuration option ``preview_office_cl_parameters`` was removed with Nextcloud 28.
We expect LibreOffice to be started with the given parameters, so it's unfavorable to have a configuration option to change the parameters.
