Description mayeul.cantan 2018-04-19 19:47:37 UTC
From https://specifications.freedesktop.org/mpris-spec/latest/ :

> The Media Player Remote Interfacing Specification is a standard D-Bus interface which aims to provide a common programmatic API for controlling media players.
> It provides a mechanism for discovery, querying and basic playback control of compliant media players, as well as a tracklist interface which is used to add context to the active media item.

It is actually a nice fit for slideshows, with Gwenview adding support to it lately: https://www.kde.org/announcements/announce-applications-18.04.0.php

Most controls are not mandatory, including the ones that are not a good fit to a slideshow: play/pause/stop/seek (though I guess they could be enabled if there is a video playing? I am not sure every mpris client supports this).

A nice touch would be to add a slideshow miniature trough the mpris:artUrl metadata :)

This would allow the following:
* Control via media keys son some desktop environments (includes gestures, remote controls, hardware buttons, etc)
* Control via widgets on some desktop environments (including the ones that could be on a lock screen, for example)
* Control via any MPRIS controller (including remote ones, such as KDE Connect's)
