[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

To clarify: to make the playback control buttons show up all you need to do is open any Youtube video, for example. Now it doesn't work (seems to be controlled by media.hardwaremediakeys.enabled property, right?)

[Alastor Wu [:alwu]]

Hello, if I understand your situation correctly, you still have media.hardwaremediakeys.enabled=true but now no Firefox control would show when playing the video? If so, would you mind to follow this instruction, but add ,MediaControl:5 in the end of log modules, after selecting Media Playback preset? Thank you so much!

It doesn't work, I opened a random YouTube video and didn't see any media control widget in xfce.

I wonder that Firefox is present in the list of players, but for some reason media buttons are not displayed, although with audacious, for example, everything works.

    <property name="plugin-4" type="string" value="pulseaudio">
      <property name="items" type="empty"/>
      <property name="enable-keyboard-shortcuts" type="bool" value="false"/>
      <property name="mpris-players" type="string" value="audacious;firefox.instance_1_82"/>
      <property name="enable-multimedia-keys" type="bool" value="false"/>
    </property>

From your first log file in the comment4, what I see is the Dbus connection was established too late and we tried to emit signal to dbus before the connection (No D-Bus Connection. Cannot emit properties changed signal .

However, in your new profile in the comment12, I collect those failed tasks as a pending task, and emit the change again after the connection is built (Emit pending signal!), and no error appeared when dispatching those tasks and all emit tasks (g_dbus_connection_emit_signal) seem succeeded after that.

Hello Martin, are you familiar with Dbus? Do you know any reasons why even dbus emit signal succeeds, but there is still no media control displayed? I wonder if it's related with the different desktop environments. Thanks!

What I noticed when I compared the output in dbus-montor between FF and audacious is that the PropertiesChanges signal is missing the PlaybackStatus property in Firefox.

See: PlaybackStatus

Yes, D-BUS/MPRIS is implemented in Widget/Gtk so it's Linux specific. Will look at it.

Do you still see the issue? I'm unable to reproduce with Fedora 42 and XFCE 4.20 with Firefox 144.0.2:
