Description Antonio Rojas 2016-07-09 09:02:24 UTC
The MPRIS controls in taskbar tooltips are not appearing in Plasma 5.7. This worked fine in the beta, and downgrading plasma-desktop to 5.6.95 fixes it, so it's a recent regression. The media control applet works fine.

Reproducible: Always
Comment 1 Antonio Rojas 2016-07-09 09:26:19 UTC
After some more testing, this seems to affect only Amarok.
I've bisected it to commit 0d6442d in plasma-desktop
Comment 2 Eike Hein 2016-07-10 06:25:25 UTC
Please attach the following information:

1) The name and location of Amarok's .desktop file on your system

2) xprop output for the Amarok window

Kai, thoughts? Going by the above the heuristic should produce a usable launcher URL from window metadata.
Comment 5 Kai Uwe Broulik 2016-07-10 09:01:45 UTC
Probably Amarok's desktop file not matching what it announces on MPRIS. Can you check the DesktopEntry Amarok announces in its MPRIS interface? The commit that changed it is [1] but since the new approach is how it should have been from the beginning, this is a bug in Amarok fwiw.

Comment 6 Eike Hein 2016-07-10 09:08:49 UTC
I just installed Amarok, here's the DesktopEntry:

kde4-amarok

Reassigning to Amarok.

Since there is not much activity in Amarok-land nowadays, would be great if someone could review and commit it.
Comment 8 Antonio Rojas 2016-07-10 10:24:48 UTC
And the same fix for juk

Fix MPRIS2 DesktopEntry value

According to the MPRIS2 spec, the DesktopEntry value should be
"the basename of the .desktop file" [1], not the desktop-file-id. So
for amarok it should be "amarok" and not "kde4-amarok", regardless of
where the desktop file is installed. This fixes displaying MPRIS
controls in the Amarok taskbar tooltip in Plasma 5.7

[1] https://specifications.freedesktop.org/mpris-spec/latest/Media_Player.html#Property:DesktopEntry

Testing done by Antonio:

Player controls are displayed again in the Amarok taskbar tooltip in Plasma 5.7.
