Description medin 2021-06-09 20:11:11 UTC

If you scroll mouse over media player icon widget, the result differs from an app to another :
- With Elisa, no audio OSD is displayed but the action is relayed to the player and its sound level is changed.
- With VLC and Firefox, audio OSD is displayed with each increment/decrement action and the event is relayed to the player and its sound level is changed.
- With Clementine, audio OSD is displayed only when sound level reach 100% but the action is relayed to the player and its sound level is changed.
- With SMPlayer it shows weird behavior and get stuck between random values.
- With MPV and QtAVPlayer the scroll has no effect on the player.

The scroll action simply sends standard MPRIS commands to the app currently being controlled by the applet; it's up to apps to interpret those actions as they see fit. You would need to file bugs on the individual apps to correct any behavior that you find objectionable.

I would rather remove/disable media player widget than do it :) because even if reported it's impossible to fix it with that many players.

What I want to know is which one is the correct response that should be given ? the one from Elisa ?

I have no idea. :) I don't know if there is a canonical standard for what is right and what is wrong here.
